Playwright offers a lot of reasons for people to adopt it for their next projects or continue using it across teams. A few most popular of them are as follows:
Free and open-source:
Playwright is free to use and adopts the open-source software development approach. This means that we can leverage everything that the framework offers without spending any money and get access to its code as well. Once we get access, we can modify the framework according to our requirements and use it internally within our organization. Open-source also encourages collaboration within teams and frankly, there are millions of testers who work on individual projects and are short on cash. Open-source products help such individuals and small firms and therefore such projects are always encouraged for usage and expansion.
Multiple browser engine support:
Playwright provides support for all the major browser engines including Chromium, WebKit, and Firefox. Since these are browser engines, they cover a wide variety of browsers that have been developed over them.
Multiple platform support:
Playwright supports all three major operating systems viz. Windows, Linux, and macOS.
Multiple tab support:
Playwright provides support for tests that span over multiple tabs in a browser and even multiple users.
Prevents flaky tests:
Flaky tests are a major concern for testers as they often result in test failures at an unprecedented time. Playwright provides three strong features to deal with test flakiness and strengthen the test cases.
- Auto-wait – One of the primary causes of flaky tests is taking action on elements that have not become actionable yet. This is possible even with the timer events we are familiar with in testing. Playwright provides an auto-wait feature that waits for an element till it has become actionable to execute actions on it. This prevents flakiness in the system.
- Dynamic web assertions – Web elements have increasingly become dynamic in nature due to which the assertions fail as the element has not appeared yet. Playwright provides assertions that suit this behavior and keeps retrying until the conditions are met.
- Tracing – The tracing method is used in software engineering to keep logs and other data for future introspection of the process. Playwright adopts the same methods to keep logs, screenshots, and videos of flaky tests to eliminate them completely from the cycle.
Using all these three features, Playwright can successfully prevent time wastage on flaky tests for the testers.
Saves authentication state:
In a lot of the test automation tools, testers need to create multiple login scenarios for multiple tests. These take extra time and extra steps for test execution. With Playwright the authentication state can be saved and reused with subsequent tests to skip this overload completely.
Supports parallel testing:
Playwright supports parallel testing which as we know, due to the high complexities of web applications these days, is an important characteristic to have in an automation tool.
Supports CI runs:
Continuous Integration runs help make sure that the new code we have written does not impact any previous code and that the integrated code works smoothly. These runs are generally automated and with so many awesome open-source tools like Jenkins, we can find them attached to every project today. To execute tests in the CI environments for efficiency, our test automation tool should support CI runs. With just a single command of npm ci, Playwright tests can be absorbed by the CI pipeline and we can start scripting test cases according to the requirements.
Faster execution:
There are numerous accounts of testers running the tests on Selenium, DevTools, and Playwright to compare the speed between these two tools.
