bUnit is a testing library for Blazor components that make tests look, feel, and runs like regular unit tests. bUnit makes it easy to render and control a component under test’s life-cycle, pass parameter and inject services into it, trigger event handlers, and verify the rendered markup from the component using a built-in semantic HTML comparer.

Bunit should run tests with component which do constructor injection #1578

Closed beauchama closed 2 weeks ago

beauchama commented 2 weeks ago

Is the feature request related to a problem? Please elaborate.

Hello! I encounter a problem with Bunit which can't run tests because the component inject services from the constructor. The constructor injection is a new feature for Blazor from .NET 9.0. I consider is not a bug because Bunit doesn't use this new approach and it is normal!

I understand that at this moment .NET 9.0 is not ready (release canditate 2) but it will be ready in november. I just wanted to put a trace. It will be nice that Bunit can run tests with this new feature :D

It is not a big problem because I can use the [Inject] attribute.

Additional context Here how it is used the constructor injection. It is same thing if we use the Inject attribute image

The error from the test image

Yeah, we need to ensure we have support for this. Should be a straightforward fix, but something we need to prioritize. Thanks for putting this on our radar.

@linkdotnet lets put this on the todo list for next fridays "bUnit dev sesions" stream.

Sure - hopefully it is straightforward and you can finally tackle the TS->C# stuff :D

I fiddled around and the fix is indeed straightforward.
