Playwright: Advanced Features and Annotations
Discover how to leverage advanced Playwright capabilities such as mobile device emulation to test responsive designs, utilize test annotations to control test execution, and use the Inspector tool for interactive debugging. This lesson equips you with methods to enhance test coverage and manage failing tests effectively.
We'll cover the following...
Let’s explore the advanced features of the Playwright framework that front-end developers and SDETs can and should use.
Note: Measuring code coverage is also considered a powerful capability within software test automation. Keep in mind that for Playwright, the code coverage with Istanbul is currently supported on Chromium-based browsers only.
Emulating mobile devices
As opposed to the Cypress framework, Playwright offers built-in mobile device emulation capabilities that can validate against the mobile device viewports and color schemes to show how a web application will look and behave. While it doesn’t replace a real mobile device test, it does extend the test coverage capabilities within Playwright. Additional mobile-specific capabilities center on specifying the geolocation, time zones, and locales of the web application under test.
