Hi Remco,

I'd like to use Memberdata and see them in Test Window. Resharper displays the two scenarios just fine, but NCrunch Shows only "Kata" and from test output, it seems like it only runs BaseCasePostgres (last of the two).

Can I do anything to see the scenarios in test window?

BR, Anders

I managed to solve my problem. To me the solution was to add IXunitSerializable to my Scenario -- even if it seems to make no difference whether the interface methods contain any code.

So: This works for me, displaying two test cases in Test Window.

Fun & games:
- Remove the IXunitSerializable and it doesn't work. No test cases under test.
- Remove ToString() override -- you get a very nice serialized-to-string version of Scenario, but only for first instance.

Good enough for me -- nothing you need to do on NCrunch side.

public Class1Tests(ITestOutputHelper output)

}

[Theory]
[MemberData(nameof(All))]
public void T1(KataScenario s2)
{
_output.WriteLine(JsonConvert.SerializeObject(s2, Formatting.Indented));
}

public static IEnumerable<object[]> All()
{
yield return new object[]
{
new KataScenario("BaseCase", new DateTime(2025, 9, 1))
};

yield return new object[]
{
new KataScenario("EdgeCase", new DateTime(2025, 10, 1))
};
}
}

public class KataScenario : BaseScenario
{
public KataScenario() : base("No name")
{
}

public KataScenario(string name, DateTime dateTime) : base(name)
{
Name = name;
DateTime = dateTime;
}

public DateTime DateTime { get; }
}

public class BaseScenario : IXunitSerializable
{
public BaseScenario(string name) : this()
{
Name = name;
}

public BaseScenario()
{
}

public string Name { get; set; } = null!;

public void Deserialize(IXunitSerializationInfo info)
{
}

public void Serialize(IXunitSerializationInfo info)
{
}

public override string ToString()
{
return Name;
}
