Software testers employ various types of tests to ensure that an application or software is working as expected. Though both smoke and regression testing are types of tests that testers use for this very same objective to test every new build of an application, they each solve different purposes and are employed at different stages of software testing as well. If you are looking to find out what both of these tests are, how they differ, and when you can use them to ensure maximum quality with your testing, you’re at the right place. So let’s get started by defining both of these tests and then take a deeper dive to explore the difference between smoke and regression testing with a comparison table.
What is Smoke Testing?
Since software testing is an integral part of the Software Development Life Cycle (SDLC), we cannot simply start testing the software even though it is ready enough to be tested. But how will we know if it is ready or not? That is where smoke testing comes into play. It helps testers to determine if the primary/core functionalities of the software are stable enough and working properly to be tested. But it is important to note that smoke testing is not only done at the beginning to validate the first build. Rather, It will be performed after every new build. Being a leading software testing company in USAsoftware testing company in USA, we never start our testing process for a new build without performing smoke testing.
Let’s assume that you have to perform smoke testing for an E-Commerce application, the following aspects of the application will be tested.
Installation & Launch
Adding/removing a product to the Cart
Adding/removing a product to the Wishlist
Completing a Purchase
How did Smoke Testing get its name?
The term ‘smoke testing’ initially originated in electronic hardware testing. The implication here was that the board being tested should be switched off If it starts to smoke when turned on. The smoke was regarded as a warning that further testing should not be completed.
What is Regression Testing?
A small misconception might arise if you think that Regression testing is the same as smoke testing because it is also tested after every new build. But the key difference between smoke and regression testing is that it is used to perform a more in-depth level of testing that goes beyond just the happy journey of a customer. It also helps to validate that the existing functionality or features of the application are not impacted by the recent change such as
Addition or removal of features or modules
Alteration of the code or configuration
Change in the requirement
Let’s consider the same example of testing an eCommerce application and assume the smoke test has passed. So these below-mentioned aspects or features of this application are just a few of the many checks that will happen during regression testing to ensure that the new feature works well on its own as well as with the existing features.
In addition to checking the purchasing process, we would now check if the payment can be made using all the available options.
We would check if we can change the privacy settings of the wishlist if it can be shared with others, and if the items added to the wishlist reflect in regular search results as well.
When it comes to the account functionality, we would also check by saving multiple addresses, validate the order history feature, check if the user can download the receipt for their purchase, and so on.
If any changes or new features are implemented, then every feature including what was tested earlier too will be tested with an end-to-end approach.
Difference between Smoke and Regression testing
We have developed this generic process flow to help you understand how these two types of testing differ from each other. Kindly keep in mind that this process flow might vary on a client-to-client basis.
Having seen the core difference between smoke and regression testing and an example to emphasize them, you will now be in a position to easily understand this direct comparison.
Smoke Testing Is Used To Check If A Build Of The Software Is Stable Enough For It To Be Tested.
Regression Testing Is Used To Verify If Any Recent Changes Have Impacted The Existing Functionality.
It Is Employed By Both Software Testers And Developers.
It Is Predominantly Used By Software Testers Alone.
It Is A Surface-Level Type Of Testing As It Is Focused Only On Certain Modules And Performed On Initial & Unverified Builds.
It Is A More In-Depth Type Of Testing As It Has An End-To-End Approach And Is Performed Only On Stable Builds.
Smoke Testing Is Always Done Before Regression Testing.
Regression Testing Is Performed During Various Phases Of Testing.
It Doesn’t Require Much Time Or Resources To Be Done.
It Requires A Lot Of Time, Resources, And Effort To Be Done.
It Is Purely An Acceptance Type Of Testing As It Validates The Build And Prevents Further Testing If It Doesn’t Pass.
Though Functionalities Are Tested, It Is Not A Purely Acceptance-Based Type Of Testing As Any Issues Found In This Phase Don’t Prevent The Application From Being Further Tested.
Smoke Testing Definitely Requires Documentation
Regression Testing May Or May Not Require Documentation Based On The Need.
We hope you now have a clear understanding of the difference between Smoke and Regression Testing. Though there are a few similarities, both are crucial tests that have their own purpose. But performing regression testing for a growing product can be a challenge to many as it requires the right personnel and a lot of effort. Being an experienced regression testing company, we have been able to perform regression testing in the most efficient way to ensure not just quicker time to market, but also to ensure quality on arrival. So we will be publishing more such informative content in the coming weeks and highly recommend you to subscribe to our newsletter.
Technology and its ever-evolving nature can be quite challenging to comprehend, especially if one isn’t technologically adept. Not to mention that with every innovation, new terminology comes up.
Today, we’ll be discussing the differences between web services and APIs, two terms that many tend to interchange mistakenly.
What Are Web Services?
Web services are software components that allow applications to communicate over the internet. They are like APIs that don’t require written code, but they do need additional web programming to work.
There are two types of web services: SOAP and REST. SOAP forms the base for web services that use structured data, such as XML and JSON. In this type of web service, a client accesses an endpoint, which it uses to get the data it needs. This data gets sent back to the client, using it for whatever purpose.
On the other hand, REST follows a more straightforward approach to web services. It doesn’t require any structured data and mainly functions when you only need a small and specific set of data.
What Are APIs?
Application Programming Interface (API) is a piece of code that allows new and existing software applications to interact with other applications. In addition, APIs make it possible to transfer data and content between different applications, allowing them to function the way you want them to.
You can think of an API as a way for third-party developers to access your product and build on it. If a company wants to create a new feature, it can use the API to access your company’s data.
You have likely come across this feature before. An excellent example would be the function that allows you to use your Facebook account to log in to other applications, like Spotify. Booking a flight through travel sites is also one example of using APIs in real life.
Which One Does Your Business Need?
APIs and web services sometimes overlap in that all web services are APIs, but not all APIs are web services. Furthermore, APIs can function online and offline while web services cannot.
Aside from these key distinctions, APIs and web services also differ in terms of functionality. The question now is, which one does your business need? If you’re searching for something that can perform one of the following, then you’re looking to have APIs for your business.
Provide information about a subject matter
Offer the ability to request information
What Happens Next?
The first step is to find a software developer if you don’t have one in-house. They can take your business’s idea and create an application based on it. Your team should also finalize ideas for your web service during your search.
Having a solid idea to present makes it easier to collaborate with the software developer, who will likely offer their input on improving the final product. After extensive meetings, the software developer will work on your web service, and then you will need a quality assurance (QA) company to test it out.
QA companies have the programmers and resources to test your web service for flaws during the development phase. They can also try the application before its official release, providing feedback to the software developer. Working with a QA company is a must since you don’t want your web service going live only to find out later on that it has numerous bugs and security flaws.
Web services are programmatic interfaces for software components utilized to connect apps, sites, and various other services over the internet. They are designed to support the exchange of data between applications, and they send, receive, and process data over the web.
If you aren’t sure if you need web services, we recommend reviewing what a web service can do to see if it fits your business requirements. Additionally, you must keep in mind that working with developers during this endeavor can also make the process easier to understand.
Should you push forth with web service development, you need to keep in mind that a QA company can ensure the successful launch of your web services. Codoid is a leading quality assurance company that strives to implement the best possible strategies to check if your web service is ready for launch. Contact us today to get started!
Today, hardly anyone doubts the need for rigorous software testing. In fact, the experts agree: in 2015, a military airplane crashed into the ground, killing those on board. The evidence later showed that an error in the programming caused the crash. Without extensive tests to check every line of code, could this tragedy have been prevented? The experts seem to think so.
Most bugs are not tragic. However, when a company tries to save money on testing, maintenance costs usually skyrocket later on. In many countries, more and more software development companies realize this because the demand for both manual and automation QA testers is growing steadily.
Unfortunately, there is one problem with being a tester, and it is a big one: there just aren’t enough of them. With all the successful game franchises and new, exciting products constantly in development, more and more people are considering QA as a career choice, which means that the competition for jobs is getting fiercer. At the same time, more and more companies are offering premium wages for testers with proper skills; this creates an even greater incentive to learn how to test. And yet, before you quit your current job to become a full-time tester, you have to ask yourself, “what do I need to be a successful tester?”
Codoid, one of the best automation testing companies, answers this question:
Excellent Communication Skills
Although it may seem strange for a tester, communication is one of the essential skills for any software tester. After all, what would be the point of testing a product if no one told you whether it passed? If a tester cannot properly communicate what they have found to their team, that tester is of no use to the company. They will be of even less use if they cannot communicate what needs to be done. A tester who cannot write professional bug reports and clearly explain how to fix the bugs will cause endless frustration on the programmer’s part and messy, confusing code on the programmer’s output.
Programmers are too familiar with their code and too eager to move on to the next thing to look for bugs. Testers, however, have a more objective methodology: they know that even the tiniest slip-up can have disastrous consequences. This is why it is invaluable for testers to be curious. They need to be able to ask “what if?” and test every possible outcome, no matter how unlikely it might be.
A tester needs to find errors in that sequence and infer how the test should be carried out to meet the desired results. A tester needs to see the big picture, not just the individual lines.
Attention to Detail
Testers are finders of small, seemingly trivial errors. To them, every detail matters. They will notice if a word is misspelled, a button is positioned in the wrong place, or a graphic is out of place. Although it is not very glamorous, it is an essential part of the job.
To effectively test a program, a tester needs to have an end-user perspective. What is the feature supposed to do? How does it work? And, more importantly, how is it supposed to make the users feel? A tester needs to imagine himself as a regular user and think like one. The whole point of testing is to ensure that the end-user is getting what he wants and needs.
It is not easy to become a tester, but it is hardly impossible. The only thing you need to do is ask yourself this: do I meet all the requirements? If yes, you’re on your way to a successful career. If not, maybe it’s time to start. Whether you decide to learn how to test on your own or at a school, numerous free resources are available online. You can begin with the basics: go over testing terms and definitions, perfect your test planning skills and learn how to use test scripts. As you get more comfortable with the material, start testing yourself: play a game and think about how to test it, and when you’re ready, you can start looking for work in QA companies.
HTML, expanded as HyperText Markup Language is used to define the structure of the content in a webpage. HTML has its origins dating back to 1980 and its first version was officially launched in 1993. Since HTML5 is the most recent version, we will be discussing the key differences and upgrades that were introduced in HTML5. We will be able to understand the advantages that HTML5 has to offer when we pit HTML vs HTML5. We will also be exploring the history of HTML to see how it has transformed over the years.
As stated earlier, the beginning of HTML traces all the way back to 1980. Physicist Tim Berners-Lee, a specialist at CERN (European Organization for Nuclear Research) proposed a new “hypertext” framework that can be used for sharing reports and documents. Ultimately, Tim Berners-Lee got together with renowned frameworks engineer Robert Cailliau to introduce the triumphant proposition called the World Wide Web (W3).
The main proper report of HTML was distributed in 1991 under the name ‘HTML Tags’. It is considered a PC relic in today’s world. Though this move was made in 1991, the initial authority proposition to change HTML into a standard was made in 1993 by the IETF (Internet Engineering Task Force). The first version of HTML is regarded as HTML 1.0 and it had 18 elements.
HTML did not boom immediately and it also lacked a lot of basic features such as changing the font, including images & tables, and so on. So in 1995, IETF arranged for a gathering to create the HTML 2.0 norm that retained all the elements from HTML 1.0 and added a few features as well. This is the last set of HTML guidelines that were distributed by IETF.
The HTML guidelines started getting distributed by another standard association called W3C (World Wide Web Consortium) instead of IETF from 1996. So on January 14, 1997, the HTML 3.2 variant was distributed by the W3C. It introduced a lot of great features like Java applets, text streams around pictures, and so on.
HTML 4.0 (A revised variant of the first distribution of December 18, 1997) was distributed on April 24, 1998. It came with significant additions like CSS templates, the ability to remember little projects or scripts for the sites, working on the openness of the planned pages, complex tables, and upgrades in the structure. A rather update came in the form of HTML 4.0.1 on December 24, 1999. It was a modification and update of the HTML 4.0 form, so it didn’t address a lot of critical aspects.
With the distribution of HTML 4.0.1, the normalization movement of HTML halted as the W3C zeroed in on the improvement of the XHTML standard. So in 2004, organizations like Apple, Mozilla, and Opera expressed their anxiety about the absence of W3C’s interest in HTML and decided to arrange another affiliation called the WHATWG (Web Hypertext Application Technology Working Group). Owing to the strength of the organization that made up WHATWG, W3C came back to the normalizing movement of HTML and distributed the initial HTML 5.0 drafts in March 2007 and the first authority draft on January 22, 2008. Corresponding to its movement with HTML, W3C also proceeded with the normalization of XHTML, a high-level adaptation of HTML.
HTML vs HTML5
Audio and Video Tags
With the introduction of
Games & Interactive Media
Browsers can display interactive 3D graphics using the computer’s own graphic processor. The need for any extra software or plugin to run games or any interactive media in web browsers also has been eliminated.
HTML employed cookies to store temporary data. Whereas, HTML5 utilizes web SQL databases, web storage, and application cache for storing the data offline. Since it became possible to store the data on the user’s device, certain app functionalities will work properly even without having an active internet connection.
We were only able to add vector graphics in HTML by VML, Flash, Silverlight, and other such technologies. But HTML5 introduced the ‘svg’ tag that enables us to include vector graphics directly.
The ability of HTML5 to generate better forms, the elimination of the flash player dependency, and general improvements like the introduction of the header, footer, and nav that adds the much-needed structure to the website make HTML5 a more mobile-friendly option in this HTML vs HTML5 comparison.
Since HTML5 can be used for deployment across various platforms, it acts as a huge time and money saver during the development phase.
Drag and Drop
HTML5 made it possible for the objects on the page to move according to the user’s cursor movement. So HTML5 was also able to enable drag and drop effects that HTML lacked.
The look of the webpages also greatly improved with HTML5 supporting more fonts that can be displayed in a wide array of colors and with different effects as well.
The introduction of the charset attribute meant that the character encoding process which was long and complicated in HTML got simplified in HTML5.
In addition to that, the ping attribute that came in HTML5 makes it possible for a list of URLs to be notified if and when a user clicks on a particular hyperlink. So the geolocation tracking and such features make HTML5 more resourceful when it comes to tracking and monitoring usage.
Disadvantages of HTML5:
Now that we have seen the HTML vs HTML5 comparison, let’s explore the few downsides that need improvement.
Since HTML5 requires modern browsers to access it, users utilizing old versions of the browser will face issues while accessing a website. There are also browser compatibility issues. So users might get unnecessarily frustrated with the website though there are no issues.
The language is always a work in progress and so you would have to be constantly following for any changes that might cause issues to your site. Though we can benefit from improvements, practically it might work as a threat.
Since media licensing is an issue in HTML5, it cannot produce dynamic outputs. Though we can embed audio files, graphics, interactivities, and videos, we will not be able to use HD videos and rich visuals that will make us miss Adobe Flash.
The security elements offered are also very limited.
Despite the few advantages, there is no denying the fact that HTML5 is very easy to use in comparison to HTML all thanks to the simple syntaxes. A few HTML tags were even removed completely in the update and a few tags were changed to a different syntax. For example, ‘dir’ was changed to ‘ul’. We hope you had a good time reading our HTML vs HTML5 comparison and learned the key differences between the two as well. As one of the top QA companies, we will be constantly updating a lot of useful information through our blogs. So make sure to stay tuned to this space for more.
Not many know that there is a lot of difference between Quality Assurance and Software Testing. Though they both contribute towards better software quality, they differ in terms of goal, approach, and so on. To put it in simple terms, software testing is the process of finding bugs that already exist in the software. Whereas, Quality Assurance is the process of preventing the creation of such bugs and future problems. So we would first perform software testing to find all the bugs, then with the available data, we will be able to perform quality control to achieve quality assurance. As a leading QA company, we have been able to successfully test products and provide quality assurance to many of our clients. So in this blog, we will be focusing on the core differences between QA and Software testing and explore why Quality Assurance is important.
The Differences between QA and Software Testing
Quality Assurance is much broader in scope as covers every process, policy, tool, guideline, training, workflow, etc. that a team will need to meet with their quality objectives. So software testing is basically a sub-branch of the quality assurance process. Now let’s take a look at the tabulated version of the key differences between QA and Software Testing.
The Primary Objective Is To Make The Application Bug-Free.
The Primary Objective Is To Make The Application Meet The Stakeholder’s Expectations.
Performed Once The Code Has Been Written.
Involved In Every Step Of The Development Process.
Checks Or Validates The Behavior Of The Application.
Improves The Application’s Quality Using Various Methods, Tools, Policies, Etc.
It Is Reactive In Nature As It Is A Corrective Action.
It Is Proactive In Nature As It Is A Preventive Action.
Focused On The Product.
Focused On The Process.
Developers Or Testers Perform The Tests.
Quality Assurance Activities Are Followed By All. (Stakeholders, Business Analysts, Developers, And Testers)
The Importance of Quality Assurance
We know for a fact that lack of bugs alone doesn’t make a quality product. If we were to go by an analogy, we can consider a dish that has been cooked in accordance with the given recipe & procedure. But what if there was something wrong with the recipe or the cooking process itself? The consumer still may not like the food though everything went according to plan. Likewise, an end-user might not feel satisfied with your product though it is bug-free.
Moreover, believing that the software being developed will have zero errors is a fallacy. Since we are aware of the obvious result, is it not wiser to follow quality assurance methods to minimize the effects of any quality issues later down the pipeline? It is impossible for the software tester who receives the code with the bugs to have any control over the development process. So the more attention and effort you put into quality assurance, the easier it gets while testing a product.
So it is evident that creating a successful product without either of these two is not possible. Though companies might have an internal team for executing basic tests, it will not be enough. A dedicated QA team will be mandatory as we all know that quality cannot be tested into a product. If there are any doubts regarding the team’s expansion, one can always outsource their QA needs to one of the best outsourcing companies such as us to get the job done without breaking a sweat while still staying on budget. We hope you are now clear of the various differences between QA and software testing
Making a career choice is no easy task, you should know if you’re on the right path by exploring various options, you should then clear any and all misconceptions you might have in the role by taking a deep dive. Following this, you’ll have to check the various skills you’ll need, the certifications to work for and so much more. As a leading software testing company, we know what makes great software testers. So assuming you have checked other options and have made a job in software testing a viable option, we will be exploring all the avenues you’ll need to focus on to become a successful software tester. We will start by introducing you to the role of a software tester so that you will not have any fallacies about the job.
Who are Software Testers?
Software Testers, also known as QA Professionals play an integral part in ensuring the quality of the software in various parts of the software development cycle. The process of ensuring quality involves creating defined expectations that the software is expected to meet and then testing it to see if the said expectations are met. It can either be done manually or by using automation. Software testing doesn’t just require people with an eye for the details as quality goes beyond what meets the eye. Quality should be ingrained in the software tester’s mindset that doesn’t just stop issues but also prevents them from occurring by encouraging the team to follow the best practices.
Quality is such a huge deal as no user would be interested to use buggy software though it has the best features. The software will fail if the team fails to nail to user experience. So software testing isn’t just about detecting bugs, it is about ensuring smooth performance and a great user experience. So let’s take a look at the various skills you will be needing to accomplish this objective.
Skills of a Software Tester
Be it any job, you will need both technical and non-technical skills to excel at it. We will not be compartmentalizing skills based on specific methods of testing as we always believe it is important for a tester to have comprehensive knowledge across all the methods and approaches. If you find this list overwhelming, please keep in mind that these are the skills you will be needing not to just get started. So you can get better at it in the due course time.
Technical Skills Required for Software Tester
Remember how we mentioned there will be defined expectations for the application to meet with? So technically you would have to understand such expectations of the stakeholders and the end-users to create test cases that will define what has to be tested and how it has to be tested. You can’t use one type of test in all scenarios, right? So you would have to learn the different types of testing like performance testing, smoke testing, regression testing, etc., and know when to use what type of testing. Once all this is ready, you must also be in a position to execute these test cases, determine the result of the tests and create test reports. Our Software Testing Tutorial for Beginners is a great blog you can ready to learn such skills. In addition to that, you must familiarize yourself with software development approaches like agile.
Since software testers would have to understand what the code means when testing an application, it goes without saying that programming is a must-have skill for testers. In addition to that, it is important to improve your coding skills to implement automation to perform repetitive tasks as the need for automation is on the rise to keep up with the demand for quality software. Apart from being able to read and comprehend the code, you must have a high level of understanding of the widely used programming languages. You must also have a stronghold in the basics such as the fundamentals of object-oriented programming, architectures, algorithms, and so on.
Though Windows and macOS are the most commonly used operating systems for regular use, you should have a basic understanding of Linux commands as the deployment of applications like databases, web services, Docker, Kubernetes, and application servers are deployed on machines running on Linux.
Databases and SQL
Nowadays applications tend to have large chunks of data in their back-end using databases. Since software testing is about ensuring overall quality, it is vital for software testers to have ample knowledge about databases like MYSQL or Oracle. So if you have the task of validating the data in the databases, you should be able to create SQL queries to verify if the data is stored properly or not.
Just like how to test execution requires effort, test management also requires a lot of effort. Using the appropriate tools can reduce the required effort in storing test cases, bug tracking, and so on. So make sure you have awareness and as many hands-on experiences with the tools that can be helpful. As a pioneer in the industry, we have curated lists of the best test management tools and the top 10 automation testing tools every tester must know about. Make sure to visit that blog to find what tools will be best suited for the various requirements.
There is a lot a candidate can claim in their resume, and certifications can add a lot of value to your application and help you stand apart from the crowd. Developing all the above-mentioned skills should be the primary objective as there will be no use for you if you decide to get certified just for the sake of getting certified. There are various free certifications that can help you get started and a lot of paid certifications that will help you gain more recognition. So make sure to visit our blog to learn more about the best QA testing certifications that we have mentioned below.
ISTQB – Foundation Level
CAST – Certified Associate In Software Testing
CSTE — Certified Software Test Engineer
CTM — Certified Test Manager
CSSBB — Six Sigma Black Belt Certification
ISTQB – Advanced & Expert Level
It is a comprehensive list of the certifications you should focus on for your career growth and not a starter kit. You could also use platforms like Coursera and Udemy to get a lot of useful certifications.
Non-Technical Skills Needed by a Software Tester
Passion is the very first non-technical aspect that you should be strong in and we have already covered that in the earlier part of this blog. So now let’s take a look at the other non-technical skills you would have to work on.
Attention to Detail
Oversight is never an acceptable option when it comes to software testing as one small oversight issue can create a ripple effect of serious issues down the lane. Stopping assumptions is the first step towards avoiding oversight. You can even improve such skills on a daily basis with the help of memory games, puzzles, and brain teasers.
The moment you make assumptions out of the equation, there will be a natural spur of curiosity in your brain. This curiosity will play a major role in helping you find bugs that could go undetected when following conventional methods. For example, if we take a look at exploratory testing, it definitely relies heavily on the tester’s intuition, creativity, and willingness to test new waters.
Once you find a bug, you should never analyze it on a surface level, you should be able to identify the root cause of the issues. Such an approach will help you test better. Having an analytical and problem-solving mindset will also help you compartmentalize the software into smaller units and make the entire process more effective.
Organizational & Communication skills
Being well organized is definitely a must-have skill for all jobs. Even with regards to software testing, having all the data in a well-organized manner will definitely aid and boost your analytical skills. Plus, if the tester fails to use clear and comprehensible statements while creating test artifacts like test cases, test plans, test strategies, bug reports, and so on. The entire development process will see setbacks. Plus, as a software tester, you must be able to retrieve all such documents in a snap as you will never know when you will need them.
Flexibility and Team working skills
The communication skills should extend towards making yourself a team player as well. If you work in an agile environment, you would have to work in tandem with other teams as well. So make sure you show flexibility in internal aspects like willingness to perform any kind of testing. One should never stay within the comfort zone if one wants to improve and grow. Likewise, have a unified vision when working with other teams. There will be no point in playing the blame game with the developers once something bad happens.
Yes, concentrating on something deeply is definitely a good sign to get effective results. But at the same time, you shouldn’t focus on just one or two aspects completely and lose track of the other parts of the application. If that happens, you might even miss the most straightforward bugs. So make sure your work is holistic in terms of coverage.
We hope you found all of this information to be useful. As stated earlier, don’t feel overwhelmed with the many skills you would need to become successful in your journey. As a leading QA company, we always make sure to implement a boot camp training session for all our new recruits by using the discussed skills as the base. We have found it to be very beneficial and hopefully, you will too.
