[ValuesAttribute] / all enum values / dynamic data

[Lexy2]

In NUnit it is possible to run tests against all possible values - passing enum or boolean as a parameter, and this would generate test cases against every value defined in the type.

Is there such a way in TUnit?

E.g.

public enum MyEnum
{
   Value1,
   Value2,
   Value3
}

public class MyTest()
{
    [Test]
    public async Task Test_MyEnum([Values] MyEnum value)
    //                              ^^^ NUnit concept
    {
        await Assert.That(CallSomething(value)).IsTrue();
    }
}

which would run the test against Value1, Value2 and Value3.

Yes in TUnit this is just a bit more explicit.

Mark your test with MatrixDataSource

And mark your parameter with a Matrix parameter, but without any arguments. If its an enum or Boolean, it should automatically expand all known values

This technique is worth mentioning in documentation, IMHO.
