Playwright, a free automation library crafted by Microsoft and unveiled on January 31, 2020, has rapidly gained traction among coders and web enthusiasts. It addresses the requirements of end-to-end testing, backing all contemporary rendering engines like Chromium, WebKit, and Firefox. Developers can execute tests on diverse operating systems such as Windows, Linux, and macOS, whether locally or on CI systems, and select between headless or headed modes with native mobile emulation capabilities.
In Playwright, developers possess the freedom to employ NUnit base classes or MSTest base classes provided by the library for composing end-to-end tests. These classes simplify the process by supporting multiple browser engines, running tests in parallel, and providing options to adjust launch and context configurations. Furthermore, developers retain the choice to manually devise the testing infrastructure using the library.
To install Playwright with NUnit or MSTest, you can use NuGet, the package manager for .NET.
- For NUnit, you can install the Playwright package along with the NUnit adapter package using the following command in your project directory:
dotnet add package Microsoft.Playwright.NUnit - For MSTest, you can similarly install the Playwright package along with the MSTest adapter package using:
dotnet add package Microsoft.Playwright.MSTest - the project so that playwright.ps1 becomes accessible within the bin directory:
dotnet build - Install the necessary browsers. This example utilizes net8.0; if you are working with a different version of .NET, you will need to modify the command accordingly and replace net8.0 with your version.
pwsh bin/Debug/net8.0/playwright.ps1 install
