Microsoft Playwright API: A Cross-Browser Web Automation Tool
The Playwright is a cross-browser web automation tool designed to make your life as a web developer easier. With Microsoft Playwright, you can write end-to-end tests without worrying about browser compatibility.
Besides that, the Playwright library provides API for easy automation.
End-to-End Test With Playwright
Playwright's end-to-end tests run in real browsers. That said, you can test the real browser input pipeline and proprietary browser APIs like:
- Intersection Observer
Modern web apps rely a lot on these capabilities. Likewise, it is vital to test them to ensure they work as expected in your users’ browsers.
The Playwright supports users with complete control over their inputs via its Input API. It includes synthesizing all types of inputs, including:
What Can You Do With Playwright?
Are you thinking of using Playright? Here are some of Playwright’s various functions for end-to-end testing.
Configure Test Retry Strategy
Microsoft Playwright can help you tell if a particular failure was due to flaky tests. It will log information about each instance.
So, you can dig into how many times a particular failed test happened on each occasion.
The Playwright creates a new browser context for all independent tests. With browser context, you can test scenarios across many pages.
It also creates a new profile with your preferences and bookmarks. That said, it allows you the freedom to explore different topics.
The testability feature also allows developers and testers creativity in their end-to-end tests.
Designed for web applications, Playwright assertions are a new way to create and deploy dynamic web content. Checks are also automatically retried until they meet the necessary conditions.
Cut errors by configuring test retry strategy and capturing execution trace videos.
The authentication state of the context can save and reuse all tests to make them faster. This shortcut bypasses repetitive log in operations.
Each Playwright test is still in full test isolation from the other modules, so they can run without affecting one another's results.
Produce Trusted Events
You can interact with dynamic controls and produce trusted events using Playwright. The tool uses your browser's input pipeline.
With the power of selectors, Playwright can pierce through shadows and enter frames.
With the Playwright auto wait, you can explore without worrying about timeouts. The Playwright can wait for elements to be actionable before performing actions.
This tool also has a rich set of introspection events. You can collect data without navigating testing actions with flaky tests.
Get all the information you need to investigate a test failure with Playwright trace. It includes a test execution screencast, DOM screenshot, and source file.
The benefits don't stop there, though! It also lets developers view database responses without changing any code.
Inspect the page and generate selectors with Playwright Inspector.
Check the click points in your browser's console to see what happens when users click them. Also, explore execution logs to know the behavior of the different elements on the screen.
Codegen is a tool that lets you generate tests by recording your actions. It’s easy to use for any web developer. You can also save them in any language.
Multiple Tabs, Origins, and Users
The most efficient way to test your site is by creating multiple tabs, origins, and users. With this feature, you can create scenarios for your website for testing.
Likewise, it helps to pinpoint any issues with user navigation.
Final Thoughts On Microsoft Playwright
The web browser is an essential and integral part of the internet experience. Modern browsers' architecture can be complex because they run on different processes.
But Playwright solves this problem by running tests out-of-process. Now, using test runners makes Playwright free from typical limitations.
It also has modularity and extensibility, so test automation is made so much easier with Playwright.
