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.

Binge-watching is the new norm in today’s digital world and OTT platforms have to be flawless. Behind the scenes, developers and testers face many issues. These hidden challenges ranging from variable internet speeds to device compatibility issues have to be addressed to ensure seamless streaming. This article talks about the challenges in OTT platform testing and how to overcome them.
Importance of OTT Platform Testing
OTT platforms have changed the way we consume entertainment by offering seamless streaming across devices. But to achieve this it requires thorough OTT platform testing to optimize performance and seamless content delivery. Regular testing is also important for monitoring the functionality of the application across a wide range of devices. It also plays a key role in securing user data and boosting brand reputation through reliable service. Despite its importance, OTT testing is full of challenges including device compatibility and security measures.
Challenges & Solutions in OTT Testing
Device Coverage
Typically applications will be developed to work on computers and mobiles, and are rarely optimized for tablets as well. But when it comes to OTT platform testing, a new variety of devices such as Smart TVs and Streaming devices are being used. Apart from the range of devices, each of these devices will run on different versions of the software and you’ll have to cover them as well.
Even if you plan to automate the tests, conventional automation will not help you cover the vast device coverage as these Smart TVs and Streaming devices operate on different operating systems such as WebOS, TizenOS, FireOS, and so on. Additionally, there are region-specific devices and screen size variations that make it more complex.
As a company specializing in OTT testing services, we have gone beyond conventional automation to automate Smart TVs, Firesticks, Roku TVs, and so on. This is the best solution for ensuring that automated tests run on a wide range of devices.
Device Management
Apart from the effort needed to test on all these devices, there is a high cost involved in maintaining all the devices needed for testing. You would need to set up a lab, maintain it, and constantly update it with new devices. So it is not like a one-time investment as well.
The solution here would be to use cloud solutions such as BrowserStack and Suitest that have the required devices available which in and itself could be a separate challenge. A hybrid approach is recommended because it balances the need for physical devices and the cost-effectiveness of cloud solutions, ensuring comprehensive testing coverage. So prioritization plays a crucial role in finding the right balance for optimal OTT platform testing.
Network & Streaming Issues
A stable internet connection is key to seamless streaming. Bandwidth and network variations affect streaming quality and require extensive real-world testing. In this case, Smart TVs and Streaming Devices might have a strong wifi connection, but portable devices such as laptops, mobile phones, and tablets may not have the best connectivity in all circumstances. One of the major advantages of OTT platforms is that they can be accessed from anywhere and to ensure that advantage is maintained, network-based testing is crucial.
Remember we discussed maintaining a few real devices on our premises? Apart from the ones that are not available online, it is also important to keep a few extra critical portable devices that can help you validate edge cases such as performing OTT platform testing from being in a crowded place, low bandwidth area, and so on. You can also perform crowdsourced testing to get the most accurate results.
User Experience & Usability
If you want your users to binge-watch, the user experience your OTT platform provides is of paramount importance. The more the user utilizes the platform, the higher the chances of them renewing their subscription. So a one-size-fits-all approach will not work and heavy customization to appeal to the audience from different regions is required. You also cannot work based on assumptions and would require real user feedback to make the right call.
So you can make use of methods such as A/B testing and usability testing with targeted focus groups for your OTT platform testing. With the help of A/B testing, you’ll be able to assess the effectiveness of content recommendations, subscription offers, engagement time, and so on. Since you get the information directly from the users, it is highly reliable. But you’ll only have statistical data and not be aware of the entire experience a user goes through while making their decisions. That is why you should also perform usability testing with focus groups to understand and unearth real issues.
Security & Regulatory Compliance
Although security and regulatory compliance are critical aspects of OTT platform testing, they are often overshadowed by more visible issues like content distribution. However, protecting content from unauthorized access and piracy is also crucial. There will be content that is geofenced and available only for certain regions. Users should also not be able to capture or record their screen while the application is open on any screen. Thorough DRM testing safeguards intellectual property and user trust.
Metadata Accuracy
A large catalog of content is always something a subscriber will love to have and maintaining the metadata for each content will definitely be a challenge in OTT platform testing. One piece of content might have numerous language options and even more subtitle options that could have incorrect configurations such as out-of-sync audio, mismatched content, etc. Likewise, thumbnails, titles, and so on could be different across different regions.
So implementing test automation to ensure the metadata’s accuracy is important as it is impossible to test it manually. It will not be easy as maintaining a single repository against which these tests will be carried out will be challenging. You’ll also have to use advanced algorithms such as image recognition to ensure the accuracy of such aspects.
Summary
Clearly, OTT platform testing is a complex task that is not like testing every other application. We hope we were able to give you a clear picture of the numerous hidden challenges one might encounter while performing OTT platform testing. Based on our experience of testing numerous OTT platforms, we have also suggested a few solutions that you can use to overcome these challenges.

Playwright is an incredibly popular and powerful tool for end-to-end automation testing of modern web applications. It offers great advantages such as faster execution speed, great documentation, and a slew of built-in features for reporting, debugging, parallel execution, and so on. If you are thinking about building your test automation framework with Playwright or migrating from a different tool, our comprehensive Playwright Cheatsheet will help you get started with the tool quickly. As an experienced automation testing service provider, we have used Playwright in our projects for different needs and we have covered some of Playwright’s most unique and advanced methods, designed to make your testing and automation processes more efficient and effective.
Playwright Cheatsheet
We have structured our Playwright Cheatsheet in a way that it is easy for both beginners to learn and experts to quickly refer to some important snippets they might be looking for.
Basic Commands
Advanced Interactions
Browser, Context Management
First up in our Playwright Cheatsheet, we’re going to start with the basics to see how to launch a browser instance in regular mode, incognito mode, and so on.
1. Launching a Browser Instance
- chromium.launch(): Initiates a new instance of the Chromium browser.
- browser.newContext(): Establishes a fresh browser context, which represents an incognito mode profile.
- context.newPage(): Generates a new browser tab (page) within the context for interaction.
// Step 1: Initiate a new instance of the Chromium browser
const browser = await chromium.launch({ headless: false });
// Step 2: Establish a fresh browser context
const context = await browser.newContext();
// Step 3: Generate a new browser tab within the context
const page = await context.newPage();
2. Creating a Persistent Context
You can use persistent contexts to maintain session continuity and reuse authentication states across tests. It allows for testing scenarios where user sessions need to be preserved.
// Launch a persistent context using the specified user data dir
const context = await chromium.launchPersistentContext(userDataDir, {headless: false });
Selectors & Mouse Interactions
Once the browser instance has been launched, the next steps in the automation will involve keyboard and mouse interactions which we will be seeing now in our Playwright Cheatsheet.
1. Using Selectors for Element Interaction
- page.goto(): Directs the browser tab to a specified URL.
- page.click(): Locates and triggers a button with the identifier Example: ‘submit’.
- page.fill(): Finds an input field with the name ‘username’ and inputs the value.
- page.selectOption(): Identifies a dropdown menu and chooses the option.
await page.goto('https://example.com');
await page.click('button#submit');
await page.fill('input[name="username"]', 'example_user');
await page.selectOption('select[name="city"]', 'New York');
Checkboxes and Radio Buttons: Easily toggle checkboxes and radio buttons using locator.setChecked() in Playwright. This method simplifies the process of both selecting and deselecting options.
// Step 3: Locate a checkbox using its label
const checkbox = page.getByLabel('Terms and Conditions');
// Ensure the checkbox is checked
await checkbox.setChecked(true);
// Step 4: Assert that the checkbox is checked
await expect(checkbox).toBeChecked();
type() : The type method in Playwright is used to simulate keyboard input into a text input field, text area, or any other element that accepts text input.
await page.getByPlaceholder('Enter your name').type('John Doe');
press(): The press method in Playwright is used to simulate pressing a key on the keyboard. This method allows you to automate keyboard interactions with web pages.
await page.keyboard.press("Enter");
title(): The title method in Playwright is used to retrieve the title of the current web page. You can use this method to extract the title of the web page you are interacting with during your automation or testing scripts.
const pageTitle = await page.title();
console.log(`page title is : ${pageTitle});
check(): The check method in Playwright is used to interact with checkboxes and radio buttons on a web page.
await page.check('input#myCheckbox');
Or
await page.locator('input#myCheckbox').check();
unCheck(): The uncheck method in Playwright is used to uncheck (deselect) checkboxes or radio buttons on a web page.
await page.uncheck('input#myCheckbox');
Or
await page.locator('input#myCheckbox').uncheck();
focus(): This method can be particularly useful when you want to simulate user interactions like keyboard input or navigating through a web application using keyboard shortcuts.
await page.locator('input#username').focus();
hover(): The hover method in Playwright is used to simulate a mouse hover action over a web page element. When you hover over an element, it can trigger various interactions or reveal hidden content.
await page.locator('button#myButton').hover();
or
await page.hover('button#myButton');
textContent(): Although the textContent method is not a built-in method in Playwright, it is a standard JavaScript method used to retrieve the text content of a DOM element.
const element = await page.locator('div#myElement');
const textContent = await
element.textContent()console.log('Text Content:', textContent);
allTextContents(): In Playwright, the allTextContent method is used to find array of multiple elements in the DOM. which returns an array of textContent values for all matching nodes.
const element = page.locator('div#Element');
const textContents = await element.allTextContents();
console.log(`All Text Contents : ${textContents}`);
inputValue(): The inputValue method in Playwright is used to retrieve the current value of an input element, such as a text input, textarea, or password field.
// Using inputValue to retrieve the current value of the input field
const inputValue = await page.inputValue('input#username');
console.log('Current input value:', inputValue);
close(): The close method is the last selector we’re going to see in our Playwright cheatsheet and it is used to close a browser, browser context, or page. You can use this method to gracefully shut down browser instances or specific pages. Here’s how you can use the close method in Playwright.
// Close the page when done
await page.close();
// Close the browser context
await context.close();
// Close the browser instance
await browser.close();
2. Mouse Interactions
Clicks and Double Clicks: Playwright can simulate both single clicks and double clicks on elements.
// Single click
await page.click('selector');
// Double click
await page.dblclick('selector');
Hover and Tooltips: You can use Playwright to hover over elements and reveal tooltips or activate dropdown menus.
await page.hover('selector');
const tooltip = await page.waitForSelector('tooltip-selector');
const tooltipText = await tooltip.innerText(); // Get text from the tooltip
console.log(tooltipText);
Drag and Drop: Here are the Playwright techniques for simulating drag-and-drop interactions between elements on a webpage.
// Locate the source and target elements
const source = await page.$('source-selector');
const target = await page.$('target-selector');
// Perform drag-and-drop
await source.dragAndDrop(target);
move(): mouse.move(x, y) in Playwright is used to move the mouse to a specific position on the page. This can be useful for simulating mouse movements during automated testing. The x and y parameters represent the coordinates where you want the mouse to move, with (0, 0) being the top-left corner of the page.
await page.mouse.move(100, 100);
dragTo(): This method is useful for automating drag-and-drop interactions in your web application. Let’s see how to use the dragTo() method with a sample snippet in our Playwright cheatsheet.
//Locate the source and target elements you want to drag & drop
const sourceElement = await page.locator('source-element-selector')
const targetElement = await page.locator('target-element-selector')
// Perform the drag-and-drop action
await sourceElement.dragTo(targetElement)
Pressing and Releasing Mouse Buttons: In Playwright, you can simulate pressing and releasing mouse buttons using the mouse.down() and mouse.up() methods.
const myElement = page.locator('.my-element')
await myElement.mouse.down() // Press the left mouse button
await myElement.mouse.up() // Release the left mouse button
Context Menu: See how Playwright interacts with context menus by right-clicking elements and selecting options.
// Right-click on an element to open the context menu
await page.click('element-selector', { button: 'right' });
// Wait for the context menu to appear
await page.waitForSelector('context-menu-selector', { state: 'visible' });
// Click on an option within the context menu
await page.click('context-menu-option-selector');
Scrolling: Discover how to simulate scrolling actions in Playwright using mouse interactions. Demonstrate scrolling through a long webpage to ensure all content loads correctly or to capture elements that only appear when scrolled into view.
// Click on an option within the context menu
await page.click('context-menu-option-selector');
await page.evaluate((x, y) => { window.scrollBy(x, y); });
Note: Use stable selectors like IDs or data attributes to ensure robust tests; validate mouse interactions by asserting resulting UI changes.
Locators
As we all know, a locator is a tool for locating elements on a webpage and Playwright has a lot of available locators. Now in our Playwright cheatsheet, we’re going to see the several available methods for finding elements, and the chosen parameters are sent to the methods for finding elements.
1. getByRole(): getByRole is used to query and retrieve elements on a web page based on their accessibility roles, such as “button,” “link,” “textbox,” “menu,” and so on. This is particularly useful for writing tests that focus on the accessibility and user experience of a web application.
// Click on an option within the context menu
await page.getByRole('textbox', {name:'Username'}).fill(‘vijay’);
2. getByText(): Although getByText() is not a built-in method in Playwright, it is a method that is often used in testing libraries like Testing Library (e.g., React Testing Library or DOM Testing Library) to query and interact with elements based on their text content.
![getByText](https://codoid.com/wp-content/uploads/2024/08/getByText-2.png" "getByText")
await page.getByText('Forgot your password? ').click();
3. getByPlaceholder(): The getByPlaceholderText method is used to select a DOM element based on its placeholder attribute in an input element.
![getByPlaceholder](https://codoid.com/wp-content/uploads/2024/08/getByPlaceholder-2.png" "getByPlaceholder")
await page.getByPlaceholder('Username').fill('vijay');
4. getByAltText(): getByAltText() is not a method associated with Playwright; it’s actually a method commonly used in testing libraries like React Testing Library and Testing Library (for various JavaScript frameworks) to select an element by its alt attribute. If you are writing tests using one of these testing libraries, here’s how you can use getByAltText().
![getByAltText](https://codoid.com/wp-content/uploads/2024/08/getByAlttext-2.png" "getByAltText")
await page.getByAltText('client brand banner').isVisible();
5. getByTitle() :getByTitle() method in Playwright is for interacting with an HTML element that has a specific title attribute.If you are writing tests using one of the testing libraries mentioned above, here’s how you can use it
![getByTitle](https://codoid.com/wp-content/uploads/2024/08/getByTitle-2.png" "getByTitle")
await page.getByTitle('Become a Seller').click();
File and Frame Handling
As we have seen how to launch the browser instance, use selectors, and handle mouse interactions in our Playwright cheatsheet, the next step would be to see how we can handle files, frames, and windows. Let’s start with files and frames now.
1. Handling File Uploads
- Easily handle file uploads during testing to ensure the functionality works as expected in your application by referring to the below code.
// Navigate to the page with the file upload form
await page.goto('your-page-url');
// Trigger the file input dialog
const [fileChooser] = await Promise.all([page.waitForEvent('filechooser'),
page.click('button-to-trigger-file chooser')]);
// Set the files to upload
await fileChooser.setFiles('path/to/your/file.txt');
2. Interacting with Frames
- Playwright allows you to interact with frames on a web page using methods like frame(), frames(), and waitForLoadState(). Here’s how you can do it.
- Use the frame() method to access a specific frame by its name, URL, or element handle.
- Get Frame using Name FrameSelector :
const allFrames = page.frames();
- Get Frame using Name Option :
const myFrame = page.frame({name: "frame1"});
or
const myFrame = page.frame("frame1");
- Get Frame using URL option :
const
Myframe=page.frame({url:"http://autopract.com/playwright/form1/"});
- Get Frame using Selector :
const
myFrame = page.frameLocator("iframe[name='frame1']");
- Navigate within a specific frame using the goto() method.
await frame.goto('https://codoid.com');
- Go back and forward within a frame using the goBack() and goForward() methods
await frame.goBack();
await frame.goForward();
- Wait for a frame to load or reach a specific load state using the waitForLoadState() method.
await frame.waitForLoadState('domcontentloaded');
Best Practices:
Automate file uploads and downloads to streamline file-related workflows. You can switch between frames using IDs or names for seamless interaction.
Windows Handling
Windows handling is an important aspect of web automation and testing, especially when dealing with scenarios where you need to interact with multiple browser windows or tabs. And that is why we have covered it in our Playwright Cheatsheet.
Playwright provides methods for handling multiple browser windows and tabs within a single browser instance. Here’s how you can work with windows handling in Playwright.
const [newWindow] = await Promise.all([context.waitForEvent('page'),
await page.getByText('APPLE iPhone 14 (Blue, 128 GB)').first().click()]);
await newWindow.waitForLoadState();
expect(newWindow.url()).toContain('apple-iphone-14');
await secondPage.close();
Best Practices:
Manage multiple windows or tabs by tracking handles and switching context as necessary. Make sure to close windows or tabs after tests to maintain a clean testing environment.
Special Capabilities
As stated earlier in our Playwright Cheatsheet, we have also covered advanced interactions in addition to the basic commands. The first of the many advanced interactions we’re going to see special capabilities such as device emulation and record and playback capabilities.
1. Emulating Devices:
- You can emulate a device for responsive testing to ensure your app looks good on various devices. This is crucial for testing mobile responsiveness and user experience.
const { devices, chromium } = require('playwright');
// Define the device you want to emulate
const iPhone = devices['iPhone 11'];
// Launch a browser and create a new context with device emulation
const browser = await chromium.launch();
const context = await browser.newContext({...iPhone,});
2. Recording and Replaying Actions
- You can automatically generate Playwright scripts with ease by recording your actions within a browser. This speeds up the creation of test scripts by capturing real user interactions.
Network Interception and Manipulation
Testing is not just about validating the results with happy paths as users might face numerous challenges in real-world scenarios. One of the common challenges can be with the network and we can manipulate it based on our testing needs. Let’s see how in our Playwright Cheatsheet.
1. Mocking Responses
Intercept and mock network responses to evaluate your app’s handling of different API responses. This is useful for testing error scenarios and verifying API integrations.
// Intercept requests to a specific URL
await page.route('**/api/data', async (route) => {
// Respond with custom data
await route.fulfill({
contentType: 'application/json',
body: JSON.stringify({ key: 'mockedValue' }) }); });
2. Simulating Offline Mode
Test how your application behaves when offline by simulating network disconnections. This ensures that your app handles offline scenarios seamlessly.
// Set the page to offline mode
await page.setOffline(true);
// Navigate to a page and perform actions
await page.goto('https://example.com');
// Restore network connection (optional)
await page.setOffline(false);
Screenshots and Visual Comparisons
Screenshots play a vital role in terms of reporting and with Playwright, you have the provision of capturing full-page screenshots and also screenshots of a particular element if required.
1. Screenshots
Capturing a Full-Page Screenshot
- You can take a screenshot of the entire page to visually verify the UI. This is beneficial for visual regression testing to identify unexpected changes.
// Take a full-page screenshot
await page.screenshot({ path: 'fullpage-screenshot.png', fullPage: true});
- There is also a provision to capture a screenshot of a specific element to focus on individual UI components. It helps in verifying the appearance of particular elements.
// Locate the element
const element = await page.$('selector-for-element');
if (element) {
// Take a screenshot of the element
await element.screenshot({ path: 'element-screenshot.png' });
console.log('Element screenshot taken'); }
Debugging and Tracing
The next set of advanced interactions we’re going to see in our Playwright cheatsheet is the debugging and tracing features that enable easier debugging and failure analysis/
Enabling Debug Mode(SlowMo)
- Using Playwright, you can execute tests in a visible browser with slow motion enabled for easier debugging. This helps you see what’s happening in real time and diagnose the issues.
// Launch the browser with slowMo
const browser = await chromium.launch({
headless: false, // Run in headful mode to see the browser
slowMo: 1000 // Slow down actions by 1000 milliseconds (1 second)
});
Capturing Traces
- You can capture detailed traces to analyze test failures and performance issues. This offers insights into test execution for debugging purposes.
// Start tracing
await context.tracing.start({ screenshots: true, snapshots: true });
const page = await context.newPage();
await page.goto('https://example.com');
// Perform actions
await page.click('selector-for-button');
await page.fill('selector-for-input', 'some text');
// Stop tracing and save it to a file
await context.tracing.stop({ path: 'trace.zip' });
Best Practices:
You can also use console logs and debug statements within tests to troubleshoot issues and enable tracing to capture detailed logs for performance analysis.
Additional Methods
In the final section of our Playwright cheatsheet, we are going to see a few additional methods such as retrying actions, using locator assertions, and forcing colors mode.
Retrying Actions
Retrying actions addresses intermittent issues by repeatedly attempting a failed action until it either succeeds or the maximum number of retries is exhausted.
const retryDelay = 1000; const maxRetries = 3; // 1 second delay between retries
await new Promise(resolve => setTimeout(resolve, retryDelay)); // Delay before retrying
Using Locator Assertions
- You can add assertions to ensure elements are visible, improving test reliability. This verifies that critical elements are present on the page.
// Check if the element is visible
await expect(page.locator('selector-for-element')).toBeVisible();
- Enabled/Disabled State Assertions
await expect(page.locator('selector-for-element')).toBeEnabled();
await expect(page.locator('selector-for-element')).toBeDisabled();
- Text and Count Assertion
await expect(page.locator('selector-for-element')).toHaveText('Expected Text');
await expect(page.locator('selector-for-elements')).toHaveCount(expectedCount);
- Invisibility Assertion
await expect(page.locator('selector-for-element')).toBeHidden();
Forcing Colors Mode
- There is even an option to simulate the high contrast mode for accessibility testing, ensuring usability for all users. This is crucial for testing the accessibility features of your application.
// Force dark color scheme
await page.emulateMedia({ forcedColors: 'dark' });
await browser.close(); })();
