What is the Microsoft Playwright JS Automation?

A playwright is an open-source tool from Microsoft that enables testers to automate their web app testing process.

Designed to work with any popular JavaScript test runner, playwright.js allows for easy scripting of common tasks. This includes navigating through a web application and filling in fields.

The Benefits of Using Playwright Automation Tool

If you’ve ever been tasked with automating the testing of a web application, you know that it can be a pain. There are different tools out there, and each has its own quirks and limitations.

But if you’re looking for a powerful and easy tool, you should definitely check out Microsoft Playwright JS. Here are just a few advantages of Playwright JS for your automation needs:

  • It’s cross-platform. Playwright’s test runner works on Windows, Linux, and macOS. Definitely, you can use it regardless of your operating system.
  • It’s open source. This means that anyone can contribute, and there are no licensing fees. This makes it a cost-effective solution for automating your tests.
  • It supports multiple browsers. Currently, Playwright offers built-in support for Chromium, WebKit, and Firefox. And more browser support is planned for the future!
  • It has a rich API. Playwright’s API allows you to do much more than just automating tests. You can also take screenshots, measure performance, or even generate test reports.
  • It’s very user-friendly. Playwright JS is designed to be easy to use, even for those new to automated testing. The interface is simple, and extensive documentation is available to help you get started.
  • It integrates well with other tools. If you’re already using a tool like Selenium for your web testing, you’ll be able to integrate Playwright JS into your existing workflow easily.

Microsoft Playwright JS is worth checking out if you’re looking for a powerful and easy-to-use automation tool for your web testing.

Some Features of Playwright JS

Playwright supports all modern web browsers and provides a variety of capabilities, such as:

  • Interact with browser contexts by mouse or keyboard. 
  • Generate Har logs. 
  • Use modern CSS selectors, providing full coverage of the W3C spec. 
  • Close browser context instances programmatically. 
  • Authenticate against HTTP Basic Auth, NTLM, and Kerberos integrations out of the box. 
  • Modify network requests made by the browser before they reach the server – e.g., to mock responses without involving server code changes.
  • Take screenshots and record videos of the test session. 
  • Inject JavaScript into web pages to drive the test or verify the application state. 
  • Wait for specific events to occur on web pages, such as navigation, network activity, or DOM updates.
  • It can be used to upload or download a test file.
  • Headless execution

How To Run Playwright Tests

It’s not as complicated as it sounds. In fact, once you know the steps, it’s pretty straightforward.

Here are the steps:

  1. Install the latest version of Node.js. Remember to restart the visual studio code after.
  2. Then, install Playwright using the command line interface.
  3. Once that’s done, create a new file and name it test.js.
  4. You’ll need to import the Playwright library and define your test case in this file. 
  5. Next, open up a terminal window. Then, navigate to your test file’s directory.
  6. Then, simply run the command “node test.js.” Your test will automatically be executed, and the results will be displayed in the terminal window. 

That’s all there is to it! Now you know how to run Playwright test automation like a pro.

Tips to Automate Your Website’s Testing Process

One area where automation can be a big help is in testing. Here are some tips to get started in the automation testing process:

Define Your Testing Goals

Before you start automating anything, you must define what you want to achieve with your tests.

Do you want to test for functionality? Performance? Compatibility?

Once you know what you want, you can design and write tests accordingly.

Open your Playwright Automation Tool

There are different options out there that can help with automated testing. That’s why it’s important to choose the tool or tools that best fit your needs.

The playwright test execution tool is one of the most popular options for automating website testing. 

Set Up Continuous Integration

Continuous integration is a process where code changes are automatically built and tested every time. This helps ensure that every change is tested before it gets deployed to production, saving time and headaches.

Run Tests Regularly

It’s important to run tests regularly, especially if your website is frequently updated. By running tests, you can ensure that your website is functioning. Plus, catch any potential issues before they cause problems for your users.

Monitor Results

Even if you’ve set up automation to handle the grunt work of testing, you still need to keep an eye on things. Otherwise, you risk missing critical issues that could cause your website to crash.

So don’t be a hands-off owner – stay involved in your first Playwright test. And ensure that your website is always in tip-top shape.
