Support services that implement IAsyncDisposable

[jmaillet]

Can TestContext and/or TestServiceProvider be made to implement IAsyncDisposable?

Is your feature request related to a problem? Please describe.
I'm getting an exception on my test TearDown method, where I'm calling _context?.Dispose()
System.InvalidOperationException : 'MyService' type only implements IAsyncDisposable. Use DisposeAsync to dispose the container.

I believe this related to #233. The MyService type uses an IJSObjectReference internally and so it implements IAsyncDisposable

Yes, that should not be a problem. Thanks for bringing this to my attention.

Can you help with a test and component that causes this error?

[jmaillet]

Sorry for the delayed response. Yes, I can do that. Happy to help.

Can I assume the component would go under Bunit.TestAssets.SampleComponents?
Where would you like the actual test to go, Bunit.Web.Tests or Bunit.Core.Tests?

Just post them here as code snippets or attach a small runnable project here that I can try locally. Then I will add the needed test cases to bUnit 🙂

No problem, here you go:
Service:

public class AsyncDisposableService : IAsyncDisposable
{
  public ValueTask DisposeAsync() => ValueTask.CompletedTask;
}

Component:

<h3>ComponentWithAsyncDisposableService</h3>
@inject AsyncDisposableService Service

@code { }

Failing Test:

var context = new TestContext();
context.Services.AddScoped<AsyncDisposableService>();
var component = context.RenderComponent<ComponentWithAsyncDisposableService>();

// throwsSystem.InvalidOperationException : 'AsyncDisposableService' type only implements IAsyncDisposable. Use DisposeAsync to dispose the container.
context.Dispose();
