- Understanding the mechanics and types of prompt injection attacks is crucial for identifying and preventing them.
- Exploring techniques and real-world examples of prompt jailbreaks highlights the severity of these security breaches.
- Mitigation strategies and future security innovations are essential for safeguarding systems against prompt injection and jailbreaks.
Understanding Prompt Injection
Prompt injection happens when someone puts harmful content into the system’s prompt. This can lead to unauthorized access or data theft. These attacks use language models to change user input. This tricks the system into doing actions that were not meant to happen.
There are two types of prompt injection attacks. The first is direct prompt injection, where harmful prompts are added directly. The second is indirect prompt injection, which changes the system’s response based on the user’s input. Knowing about these methods is important for putting in strong security measures.
The Definition and Mechanics of Prompt Injection
Prompt injection is when someone changes a system prompt without permission to get certain responses or actions. Bad users take advantage of weaknesses to change user input by injecting malicious instructions. This can lead to actions we did not expect or even stealing data. Language models like GPT-3 can fall victim to these kinds of attacks. There are common methods, like direct and indirect prompt injections. By adding harmful prompts, attackers can trick the system into sharing confidential information or running malicious code. This is a serious security issue. To fight against such attacks, it is important to know how prompt injection works and to put in security measures.
Differentiating Between Various Types of Prompt Injection Attacks
Prompt injection attacks can happen in different ways. Each type has its own special traits. Direct prompt injection attacks mean putting harmful prompts directly into the system. Indirect prompt injection is more sneaky and changes the user input without detection. These attacks may cause unauthorized access or steal data. It is important to understand the differences to set up good security measures. By knowing the details of direct and indirect prompt injection attacks, we can better protect our systems from these vulnerabilities. Keep a watchful eye on these harmful inputs to protect sensitive data and avoid security problems.
Exploring Prompt Jailbreak
Prompt Jailbreak means breaking rules in NLP systems. Here, bad actors find weak points to make the models share sensitive data or do things they shouldn’t do. They use tricks like careful questioning or hidden prompts that can cause unexpected actions. For example, some people may try to get virtual assistants to share confidential information. These problems highlight how important it is to have good security measures. Strong protection is needed to stop unauthorized access and data theft from these types of attacks. Looking into Prompt Jailbreak shows us how essential it is to keep NLP systems safe and secure.
What Constitutes a Prompt Jailbreak?
Prompt Jailbreak means getting around the limits of a prompt to perform commands or actions that are not allowed. This can cause data leaks and weaken system safety. Knowing the ways people can do prompt jailbreaks is important for improving security measures.
Techniques and Examples of Prompt Jailbreaks
Prompt jailbreaks use complicated methods to get past rules on prompts. For example, hackers can take advantage of Do Anything Now (DAN) system weaknesses to break in or run harmful code. One way they do this is by using advanced AI models to trick systems into giving bad answers. In real life, hackers might use these tricks to get sensitive information or do things they should not. An example is injecting prompts to gather private data from a virtual assistant. This shows how dangerous prompt jailbreaks can be.
The Risks and Consequences of Prompt Injection and Jailbreak
Prompt injections and jailbreaks can be very dangerous as they can lead to unauthorized access, data theft, and running harmful code. Attackers take advantage of weaknesses in systems by combining trusted and untrusted input. They inject malicious prompts, which can put sensitive information at risk. This can cause security breaches and let bad actors access private data. To stop these attacks, we need important prevention steps. Input sanitization and system hardening are key to reducing these security issues. We must understand prompt injections and jailbreaks to better protect our systems from these risks.
Security Implications for Systems and Networks
Prompt injection attacks are a big security concern for systems and networks. Bad users can take advantage of weak spots in language models and LLM applications. They can change system prompts and get sensitive data. There are different types of prompt injections, from indirect ones to direct attacks. This means there is a serious risk of unauthorized access and data theft. To protect against such attacks, it is important to use strong security measures. This includes input sanitization and finding malicious content. We must strengthen our defenses to keep sensitive information safe from harmful actors. Protecting against prompt injections is very important as cyber threats continue to change.
Case Studies of Real-World Attacks
In a recent cyber attack, a hacker used a prompt injection attack to trick a virtual assistant powered by OpenAI. They put in harmful prompts to make the system share sensitive data. This led to unauthorized access to confidential information. This incident shows how important it is to have strong security measures to stop such attacks. In another case, a popular AI model faced a malware attack through prompt injection. This resulted in unintended actions and data theft. These situations show the serious risks of having prompt injection vulnerabilities.
Prevention and Mitigation Strategies
Effective prevention and reduction of prompt injection attacks need strong security measures that also protect emails. It is very important to use careful input validation. This filters out harmful inputs. Regular updates to systems and software help reduce weaknesses. Using advanced tools can detect and stop unauthorized access. This is key to protecting sensitive data. It’s also important to teach users about the dangers of harmful prompts. Giving clear rules on safe behavior is a vital step. Having strict controls on who can access information and keeping up with new threats can improve prompt security.
Best Practices for Safeguarding Against Prompt Injection attacks
- Update your security measures regularly to fight against injection attacks.
- Update your security measures regularly to fight against injection attacks.
- Use strong input sanitization techniques to remove harmful inputs.
- Apply strict access control to keep unauthorized access away from sensitive data.
- Teach users about the dangers of working with machine learning models.
- Use strong authentication methods to protect against malicious actors.
- Check your security often to find and fix any weaknesses quickly.
- Keep up with the latest trends in injection prevention to make your system stronger.
Tools and Technologies for Detecting and Preventing Jailbreaks
LLMs like ChatGPT have features to find and stop malicious inputs or attacks. They use tools like sanitization plugins and algorithms to spot unauthorized access attempts. Chatbot security frameworks, such as Nvidia’s BARD, provide strong protection against jailbreak attempts. Adding URL templates and malware scanners to virtual assistants can help detect and manage malicious content. These tools boost prompt security by finding and fixing vulnerabilities before they become a problem.
The Future of Prompt Security
AI models will keep improving. This will offer better experiences for users but also bring more security risks. With many large language models, like GPT-3, the chance of prompt injection attacks is greater. We need to create better security measures to fight against these new threats. As AI becomes a part of our daily tasks, security rules should focus on strong defenses. These will help prevent unauthorized access and data theft due to malicious inputs. The future of prompt security depends on using the latest technologies for proactive defenses against these vulnerabilities.
Emerging Threats in the Landscape of Prompt Injection and Jailbreak
The quick growth of AI models and ML models brings new threats like injection attacks and jailbreaks. Bad actors use weaknesses in systems through these attacks. They can endanger sensitive data and the safety of system prompts. As large language models become more common, the risk of unintended actions from malicious prompts grows. Technologies such as AI and NLP also create security problems, like data theft and unauthorized access. We need to stay alert against these threats. This will help keep confidential information safe and prevent system breaches.
Innovations in Defense Mechanisms
Innovations in defense systems are changing all the time to fight against advanced injection attacks. Companies are using new machine learning models and natural language processing algorithms to build strong security measures. They use techniques like advanced sanitization plugins and anomaly detection systems. These tools help find and stop malicious inputs effectively. Also, watching user interactions with virtual assistants and chatbots in real-time helps protect against unauthorized access. These modern solutions aim to strengthen systems and networks, enhancing their resilience against the growing risks of injection vulnerabilities.
Conclusion
Prompt Injection and Jailbreak attacks are big risks to system security. They can lead to unauthorized access and data theft. Malicious actors can use NLP techniques to trick systems into doing unintended actions. To help stop these threats, it’s important to use input sanitization and run regular security audits. As language models get better, the fight between defenders and attackers in prompt security will keep changing. This means we need to stay alert and come up with smart ways to defend against these attacks.

Over the years, Selenium test automation has become an integral part of quality assurance. Despite its immense popularity, many might have faced various difficulties in the form of flaky and unstable tests. But does that imply that the issue is with Selenium? Being a leading test automation services provider, we have no second thoughts in its capacity and can firmly say that everybody can get the best out of it if they follow the best practices. Though there are no specific rules for creating your Selenium test automation scripts, these Selenium best practices will definitely act as effective guidelines. So in this blog, we have listed the Selenium best practices that one can follow to enhance the efficiency of their Selenium Test Automation.
Know Which Tests Should Be Automated
It is a well-known fact that 100% automation isn’t possible. So trying to automate every single scenario or automating every scenario that can be automated is not the best approach. So before you kickstart your automated browser testing, make sure you are clear of what tests have to be automated. When it comes to automation, always keep in mind that just because you can do something doesn’t mean that you should do it.
So start off by designing effective test cases before you start working on automation. Apart from that, analyzing if automating a scenario will result in the reduction of repetitive and tedious tasks is also crucial. So if you automate a test case that doesn’t have much frequency of occurrence, then spending that much time and effort on automating the test case is not validated. So as a first step, look for static test cases that have predictable outputs.
Choose the Best Locators
Since Selenium has a wide range of web locators available, choosing the best locators can impact the quality of your Selenium test automation. Some of the most often used web locators in Selenium WebDriver are
- ID
- Class
- tagName
- Name
- Link text
- XPath
- CSS Selector
- DOM Locator, and so on.
It’s important to pick the proper one as it will reduce the impact of user interface changes during testing. For example, if there is a dynamic scenario, link text will generally be preferable. But if you are looking for web locators that are less brittle, ID, Class, or Name would be the way to go even though it isn’t that user-friendly.
To learn more about the many ways to locate web elements and to know which locators are most suited for specific scenarios, read our blog about the different XPath methods in Selenium.
Utilize time-efficient approaches
It is not always about getting the script to work as your test scripts should also be efficient when executed. What might feel like just a few seconds will definitely have huge impacts when you have to execute the tests numerous times in different combinations. That is why we have incorporated the following Selenium best practices that will help you save loads of time.
Use Selenium Wait Commands Instead of Thread.sleep()
Various factors like network slowness or server issues can cause your web application to take additional time to load. So your automation scripts should be able to wait for all the elements to load before starting the test execution.
The Thread.sleep() method can be used for this purpose as it can pause your script for a specific amount of time.
Sleep
Sleep() waits for the number of seconds supplied in the brackets, regardless of whether the working page is ready.
There is a major flaw with this function as the script will wait for a fixed time for every scenario irrespective of the need. For example, let’s assume that you have set the sleep time to be 6 seconds. But what if the webpage that has to be tested loads in just 3 seconds? Or what if the webpage took 7 seconds to load? You will either be wasting time or getting inaccurate results because of this approach. But you can prevent such issues by utilizing implicit or explicit waits.
Wait
Explicit: The code execution is halted until a certain condition is satisfied.
Packages to import to use the Explicit wait
import org.openqa.selenium.support.ui.ExpectedConditions
import org.openqa.selenium.support.ui.WebDriverWait
Code to initialize a Wait Object using WebDriverWait Class
WebDriverWait wait = new WebDriverWait(driver,10);
Here WebDriverWait is the class, and new is the reference variable. It will either for the defined amount or for the expected condition to be fulfilled. This is just a sample and you can use the same concept with the other available expected conditions. Though there are various options, we have listed a few below,
- visibilityOf()
- alertIsPresent()
- titleContains()
- textToBePresentInElement()
- invisibilityOfTheElementLocated()
- elementSelectionStateToBe()
- elementToBeClickable()
- presenceOfAllElementsLocatedBy()
- frameToBeAvaliableAndSwitchToIt()
Example:
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[contains(text(),CODOID)]")));
By now you would have understood why we have included the usage of the wait commands in our list of Selenium best practices. Beyond the explicit wait, there are also implicit and fluent wait commands that give you more options. So let’s explore them now.
Implicit: The WebDriver is advised to keep polling the DOM until the element search is complete. By default, the time is set to 0.
Syntax
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
Fluent: It waits for a specified maximum amount of time for a specific condition. What makes it different is that it will validate the element at regular intervals before throwing “ElementNotVisibleException”.
Syntax
Wait wait = new FluentWait(Webdriver_Reference)
.withTimout(timeOut, SECONDS)
.pollingEvery(timeOut, SECONDS)
.Ignoring(Exception class)
Sample Snippet
We have mentioned a sampe snippet that will wait for 30 seconds and check the condition every 5 seconds.
FluentWait wait = new FluentWait(driver);
.withTimeout(30, TimeUnit.SECONDS)
.pollingEvery(5, TimeUnit.SECONDS)
.ignoring(NoSuchElementException.class);
WebElement element = wait.until(new Function<WebDriver, WebElement) {
public WebElement apply(WebDriver driver) {
return driver.findElement(By.id("element"));
}
});
Implicit: The WebDriver is advised to keep polling the DOM until the element search is complete. By default, the time is set to 0.
Use Assert and Verify-in Appropriate Scenarios
Let’s assume that there is a task to transport 100 boxes of apples to the market. But what if all the boxes of apples are rotten already? Will there be any use in putting all the effort and time to get the apple to the market only for it to go unsold? Likewise, there will be various scenarios where there are hard fails that will compromise the rest of the execution. Please keep in mind that Asserts should only be used if you want to stop the test execution when a hard failure occurs. If the assert condition is false, the execution will come to a halt, and no more tests will be run. So it is important to identify such bottlenecks and ensure that you use Asserts to save time.
If we take an e-commerce site as an example, such scenarios might come at the very beginning where a user is unable to login, or even in between where the user isn’t able to add any product to their cart. If these functionalities fail, there will be no point in testing the search functionality or payment process as it would all fail due to their dependency.
If the errors are not that critical, then you will be able to run the tests irrespective of the verify’s condition.
Increase Test Coverage
There is just no easy workaround when it comes to testing a website or an application across a variety of devices and browsers. The devices are further split based on the operating system they use as well. So let’s take a look at a few Selenium Best Practices that will help you increase the test coverage.
Browser Compatibility Matrix
Just like knowing what to automate, it is important to figure out the high-priority combinations that are used by your target audience. So create a Browser Compatibility Matrix by performing a product analysis to obtain detailed insights. Trying to perform automation testing with Selenium without narrowing down your target will not only be a cumbersome task, but it will also be a waste of time and resources.
Make use of Parallel Testing in Selenium
Though you are able to narrow down the device combinations, you will not always have the time to test everything one by one. Since Selenium’s parallel testing option is a major reason for its popularity, you can employ it not just to save time, but to also improve your test coverage in an efficient way. Almost all major test frameworks, such as PyTest, PyUnit, TestNG, Cucumber, and so on support simultaneous testing on a Selenium Grid. If you are not familiar with the concept of creating a Selenium Grid for distributed execution, make sure to read our conclusive blog.
Being the innovators we are, we even developed an open-source tool called VisGrid that will provide you with a UI to easily start a Selenium Grid, create & attach nodes, and so on.
Use many driver implementations instead of a single one
Since Selenium’s WebDrivers are not interchangeable, executing automated cross-browser tests on a local computer is not the same as running them on a continuous build server. It would be a mistake to assume that the following test will utilize Firefox WebDriver in that situation (or Chrome WebDriver or any other WebDriver).
When running integration tests in a continuous build environment, the test will only get a RemoteDriver object (i.e., WebDriver for any target browser). Using parameter notes to manage multiple browser types and prepare the code ready for simultaneous execution is one of the Selenium best practices (or parallel testing). LabelledParameterized (@Parameters in TestNG and @RunWith in JUnit) may be used to build small frameworks in Selenium.
Ease Code Maintenance
When working on automation tests with Selenium, it’s critical to pay attention to the test code’s maintainability and reusability. As one of the best test automation companies, we always make sure our scripts are easy to maintain by implementing the following Selenium best practices.
Use design principles and patterns, such as the Page Object Model
With the ever-increasing client expectations, a website’s user interface (UI) will inevitably change as new updates get introduced at regular intervals. So the locators for certain UI components will vary as well. This implies that QAs have to once again create new test cases for the same page or make numerous changes at various places of the script, which can be time-consuming.
So you can employ the Page Object Model design pattern to create test scripts and overcome this issue. In this approach, each web page is considered a class file in the design pattern, and each class file contains related web components.
This method greatly increases the reusability of the code while also making test maintenance easier. Read our complete guide to page object model in Selenium before you implement it.
Quarantine flaky tests
If a test keeps failing at random even if the code hasn’t gone through any changes, then it is called a flaky test. Since the testers can never be sure of the results, they will lose trust in the code and end up re-running the scripts, or debugging the scripts even though there might not be an actual defect. So make sure to quarantine such tests from your other tests. Once they are separated, make sure to analyze them and fix them before you bring them back to your test suite as flaky tests can disrupt your entire automation test suite with false positives and negatives.
Wrap Selenium Calls
You might be using various web locators such as XPath and ID to locate different web elements on the page. So the code that is regularly used in the implementation should be separated into its own API to reduce code duplication. By following this approach, you will be able to reduce the code size and enhance maintainability.
Use a standardized directory structure
Page Objects, Helper functions, and file(s) that include web locator information needed in test scenarios may all be found in the Src folder. The actual test implementation can be stored in the test folder.
When it comes to a directory structure for Selenium test automation, we don’t have a common guideline. Selenium best practices, on the other hand, proposes that we have a directory structure that isolates the test implementation from the test automation framework. This improves the test code’s structure.
Implement Data-Driven Testing for Parameterization
Hard coding test values in test automation scripts are extremely troublesome and not scalable in any way. But you can avoid the various disadvantages like code duplication by implementing data-driven testing by using Parameterization. It aids in the execution of test cases that have a variety of inputs (or data sets).
Naming Convention
Improper naming of your web elements in your automation script could lead to a lot of unnecessary confusion. You may not face any issues as long as you are the only person using the script, but you have to ensure that your script can be used by anybody. Effective naming eases code maintenance by also making it easier to find the web element you are looking for in your code. Now let’s see a few tips that can help you.
1. Add prefixes to the name of your web elements as shown in the below table as it describes the type of web elements being used. In addition to that, you can name the web element based on how it appears in the UI.
| S. No |
Web Element Type |
Prefix |
Example |
| 1 |
Text Box |
Txt |
TxtUsername,TxtPassword |
| 2 |
Button |
Btn |
BtnSignUp , BtnLogin |
| 3 |
Drop Down |
Dd |
DdCountry , DdYear |
| 4 |
Select Drop Down |
Sdd |
SddMonth , SddYear |
| 5 |
Check Box |
Chk |
ChkGender, ChkLanguage |
| 6 |
Header |
Hdr |
HdrName, HdrUser |
| 7 |
Table |
Tbl |
TblBooks, TblProducts |
| 8 |
Label |
Lbl |
LblUserName, LblPassword |
| 9 |
Image |
Img |
ImgProfile, ImgCart |
2. You can even add prefixes that denote the action to be performed on the web element.
Example:
| S. No |
Action |
Prefix |
Example |
| 1 |
Click |
Clk |
ClkLogin, ClkIcon |
| 2 |
Type |
Set |
SetMobileNo, SetPassword |
| 3 |
Verify |
Verify |
VerifyLogo |
| 4 |
Check A Check Box |
Chk |
ChkLanguage |
| 5 |
Select Value From Drop Down |
Select |
SelectCountry, SelectZone |
3. Likewise, you can make use of suffixes when creating action pages.
Example:
SignUpPage
LoginPage
4. To make it even clear, you can use a camel case to name the web elements.
Camel case is nothing but a typing convention like lower case and upper case in which the first letter of every word is capitalized.
Example:
If a text box has the label as “Email address”, name it as “txtEmailAddress”
Proper Documentation
Creating proper documentation for your automation tests in Selenium is as important as any of the other Selenium best practices we have discussed thus far.
Use Automated Screenshots to Analyse Failures
Automation Test Script running into failures is an eventuality. But we will not be sure if the failure is due to a defect in the Application Under Test (AUT) or if there is a problem with our code. So analyzing the cause of a test failure will be very crucial, and so taking screenshots is a best practice that can save a lot of time. Screenshots are not just great for failures as you can make use of screenshots as evidence for success.
To capture a screenshot, use the getScreenshotAs function in the following code sample.
File source = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(source, new File("Test Screenshot.png"));
Log and Report
Finding that one failed test case in a large test suite is like finding a needle in a haystack. So using console logs at suitable points in the test code helps us understand the issues better and zero in on the core problem.
Debug, info, warning, error, and critical are some of the common log levels that are available in most programming languages. Since adding unnecessary logs to the test implementation might cause test execution to be delayed, it is better to add logs with level errors in scenarios that enable easier tracking.
Like logging, reporting is also an important aspect of Selenium test automation as it helps determine if the test has passed or failed. You can also keep track of the progress of test suites (or test cases). This in turn helps improve the readability of the output and helps you reduce the amount of time spent maintaining test data as you can easily analyze the features and test coverage.
Set Zoom Level to 100% and Maximize the Window
Make sure to set the zoom level in your browser to 100% during your automation as it is one of the basics that should be followed regardless of which browser you opt to use. It will both provide a native mouse experience and ensure that the native mouse events are assigned to the proper coordinates.
Ensure to maximize the window as soon as the test URL is loaded as Selenium doesn’t launch the browser in the maximized mode by default.
Snippet
driver.manage().window().maximize();
Conclusion
We have seen great results by implementing these Selenium best practices in our automation testing projects and hope you will them useful in the future as well. We had listed various Selenium best practices under particular categories to enable a crystal clear understanding of how each of them impacts the testing process on the whole. So we hope you have enjoyed reading our blog and found the content to be informative as well.
by admin | Jan 31, 2022 | Exploratory Testing, Blog, Latest Post |
There are many well-known definitions for exploratory testing (ET). Out of those, the most common one was coined by James Bach and Cem Kaner. That is, “Exploratory testing is simultaneous learning, test design, and test execution”. This definition has changed over the years to become “Exploratory testing is an approach to testing that emphasizes the freedom and responsibility of each tester to continually optimize the value of their work. As a leading QA company, we achieve this by treating learning, test design, and test execution as mutually supportive activities that run in parallel throughout the project”. Since exploratory testing can be defined in many different ways from different perspectives, it is very common for many to create a few misconceptions. So in this blog, we will be myth-busting the most common Exploratory Testing misconceptions.
Exploratory Testing is not Adhoc Testing
We are starting off with this point as viewing exploratory testing as ad hoc testing is pretty much the most famous exploratory testing misconception. If you look at both these approaches on a surface level, they might seem the same. For example, both these approaches do benefit from having an experienced tester perform the tests. But if you dig deeper, you will be able to see the differences. For starters, Adhoc testing doesn’t have any structure or proper documentation. But exploratory testing does in fact have both structure and documentation and that is our next point of discussion.
Exploratory Testing needs Planning
The most common Exploratory Testing misconception is that it can be done in any random way we desire without any plan. But in reality, exploratory testers use test charters that will prevent them from going overboard by maintaining a certain boundary. If test charters provide the boundary for the scope of the tests, then time boxing creates defined timeframes for exploration.
But the point to keep in mind is that these test charters shouldn’t be too detailed. Test charters should only help you focus up and shouldn’t become like detailed test cases. In addition to that, it will also be helpful when it comes to traceability.
Exploratory Testing requires Documentation
Now we know that creating test charters will not take as much time as creating test cases as it doesn’t need to be too detailed. So mind mapping the ideas or focus points that need to be documented can help us stick to the context and make sure we are not testing beyond the documented ideas. Likewise, mind maps can also be very helpful in identifying the steps to reproduce a particular bug as we can trace the steps taken during testing. We have covered the importance of using mind maps for exploratory testing documentation in detail. Make sure to read it for additional information. Performing exploratory testing and not having even test notes will make it very difficult to keep track of the bugs that were found, and most importantly fix them as well.
Exploratory Testing requires Training
The other common exploratory testing misconception is that people believe that it doesn’t require any sort of training and can start immediately. But just as seen in the previous points, there are various techniques like mind mapping that will come in handy during exploratory testing. So make sure to train yourself with the 5 exploratory testing techniques that we have mentioned in this blog to witness the improvements.
One of the 5 exploratory techniques is Integration testing as you should be in a position to test every module that comes your way in the way you want it to be tested. You will also start seeing better results in your exploratory testing as you gain valuable experience. So make sure to keep a learning mind when you perform the tests.
Exploratory Testing is not test-case-based testing
Though you may not have had this exploratory testing misconception, the recent points might lead you to wonder if exploratory testing is almost like test-case-based testing. But in fact, exploratory testing brings the best values from ad hoc testing and test-case-based testing to achieve more robust results. For example, though we have the test charters and time boxing elements to guide us along, the limitation of staying within the test cases alone is eliminated in exploratory testing.
The tester will have the freedom to use their experience and follow their hunches to detect bugs that would usually go untraced. Plus exploratory testing can be performed even at the very initial stages of development to find and fix the bugs at the earliest. You could visit our comparison blog of Scripted Testing vs Exploratory Testing to get an even clear idea about the distinction.
We can employ both test-case-based testing and exploratory testing
We have established the fact that exploratory testing is different from the regular scripted testing in our previous point. So using both the scripted and exploratory approach when testing the same product can be an effective way to find more bugs. Having predefined scripts based on what we know alone will never be enough. So using the knowledge we gain during exploratory testing is the best course of action.
As stated earlier, you can use exploratory testing during the initial phases of development and cut off the bugs at an earlier stage. By that time, the application will be ready for us to perform scripted testing to root out the remaining bugs. Likewise, we can also use scripted tests to attain maximum coverage and use chartered exploratory tests wherever needed to bring about the best results. Speaking of test coverage, let’s move to the next exploratory testing misconception.
Exploratory Testing isn’t about Coverage
Exploratory testing is a very subjective approach that depends on the individual tester who is in control. We would have heard many say that exploratory testing expands the test coverage. The implication here is that exploratory testing will be instrumental in finding the bugs that would usually go untraced in the conventional approach. The tester will have the option to test different scenarios and target the weak spots that have been identified instead of testing everything. So though it is possible to attain maximum coverage, it wouldn’t be necessary if you couple exploratory with scripted testing.
Exploratory Testing isn’t Troubled by Complexity
By this point, you yourself know that exploratory testing can be done irrespective of the complexity of the product. Since exploratory testing is a reactive process that is influenced by what we learn during the testing process, the complexity of the product will never be a factor. Irrespective of the approach you use, you must have ample experience and skills with the different testing techniques to keep up with the complexity. In fact, you will even get better ideas for testing a complex product because of the context you can observe and understand from the hands-on experience.
Conclusion
As a leading Exploratory testing services provider, our first step towards providing better results was clearing the common misconceptions behind the approach. Just a sweet reminder that there is no conclusive evidence or definition for exploratory testing is as of now. So don’t end up with the single known definition or any not-proven conclusion of exploratory testing. Instead, charter your learning experience in exploratory testing by understanding the common Exploratory Testing misconceptions. We believe it greatly helped us out understand what exploratory testing truly is and hope this blog will be very useful for you as well.
