Documentation: Create a timeline showing the cycle of a TUnit test

[TheRumle]

One of the things I really have a hard time remembering is the exact lifecycle of a TUnit test... for instance what happens first, test discovery or test registration?

One could create a simple mermaid diagram (or drawio or whatever) that can show such a timeline or maybe just a table with phases and descriptions of what happens in those phases.

@TheRumle How's this? https://tunit.dev/docs/test-lifecycle/lifecycle-overview

Interesting. As far as I can tell, it is not possible to receive the test class instance at this point in execution? I do not see it present on the Context provided when implementing ITestStartEventReceiver.

I want to add dynamic tests after initialization of the class' resources using reflection (to get it working maybe something smarter can be done later) but without an instance of the class, I cannot get access to its resources. Any ideas on how to do it?

public class DynamicTestCreator<T> : Attribute, ITestStartEventReceiver
{
    public async ValueTask OnTestStart(TestContext context)
    {
        //Use reflection here to find relevant methods and create dynamic tests for them

    }
}

class TestResource : IAsyncInitializer
{
    public Task InitializeAsync() => Task.CompletedTask;
}

class Test
{
    [ClassDataSource<TestResource>] public required TestResource Resource { get; init; }

    public async Task RelavantMethod()
    {
        await Assert.That(new Random().Next()).IsEven();
    }
}
``

@thomhurst Good suggestion. However, I need to be able to use the Resource exposed by my test. Is there a way to get access to the instance of the test class currently executing?

[thomhurst]

On my phone right now but I believe it's TestContext.Current.Metadata.TestDetails.ClassInstance

@thomhurst You really have thought of everything 🚀
