Testing.Playwright
Quick project loosely based on the article End-to-End test a Blazor App with Playwright by Xavier Solau to allow testing an ASP.NET Core application with Microsoft.Playwright.
This also includes a Fixture logging system which was taken from one of my other projects, which used the same underlying Microsoft.AspNetCore.Mvc.Testing package.
The project uses xunit as the logging engine, although I'm sure it could be adapted to nunit easily enough.
This code 'hardcodes' the type in PlaywrightWebApplicationFactory to the web application Program class, although it could easily be made generic like the underlying WebApplicationFactory.
As xunit does not allow passing any parameters to a fixture, there are types which explicitly set the Environment (via UseEnvironment) to be Development, Staging, or Production.
Again you could inherit the fixture class and manually set a different environment if needed.
This implementation is 'opinionated' in that it always uses one browser per fixture. Xavier Solaus solution shows how it would be possible to allow the test to decide which browser to use. This would also potentially allow the tests to be run for all browsers using InlineData`.
However, by using derived fixture types you can override the Browser type, then you can simply inherit the tests class to run the same tests with different browsers, and/or environments.
This works from inside VS2022 and from the command line with
dotnet test --logger "console;verbosity=detailed"or just
dotnet test
