[BUG] Test Classes With Injected Dependencies Cause Matrix Expansion To Fail

[Xen0byte]

Description

After creating a matrix test in a class with injected dependencies, it was observed that matrix expansion fails.

Expected Behavior

Matrix expansion should work regardless of the test class constructor signature.

Actual Behavior

The permutations are not discovered, and running the test results in a failure.

Steps to Reproduce

1. create a test class with injected dependencies
2. create a matrix test
3. compile and observe that the permutations are not discovered
4. run and observe the failure

TUnit Version

1.13.51

.NET Version

.NET 10

Operating System

Windows

IDE / Test Runner

dotnet CLI (dotnet test / dotnet run)

Additional Context

Not sure if it matters, but dependency injection is managed via [ClassConstructorAttribute<T>].

IDE-Specific Issue?

• I've confirmed this issue occurs when running via dotnet test or dotnet run, not just in my IDE

Can you try 1.15.7?

Can you try 1.15.7?

Yes, will do! I'll report back with the findings shortly. Writing this, I realise that I've added the wrong TUnit version, I'll update that too.

I've updated to 1.15.11 and that works fine so far. Thank you!
