WpfTheory with MemberData parameters deserialization failure about xunit.stafact HOT 7 CLOSED

I am not an owner but let me try to understand the issue.
I believe this line throws an exception. The line is inside DeserializeSerializable method which is most probably called from here. It means WpfTheoryTestCase and other test cases should contain parameterless constructor. Also there is some helpful comment inside the base XunitTheoryTestCase class. Its parameterless constructor is marked by ObsoleteAttribute:

[Obsolete("Called by the de-serializer; should only be called by deriving classes for de-serialization purposes")]
public XunitTheoryTestCase();

Of course, we can just add parameterless constructor for all test cases but it would be better to understand your case. Could you describe it and help to reproduce?

Adding the default constructor to this type is fine. But can you please give me the repro steps so I can verify the problem and the fix?

from xunit.stafact.

In my case, it was a test case that contains an STA thread and we are doing the test case as follows:

    [WpfTheory]
    [MemberData(nameof(TestData))]
    public void Test(DateTime outDate, DateTime nowDate, bool 
       expectedResult)
    {
       //Test case logic
    }


    public static IEnumerable<object[]> TestData
    {
        get
        {
            yield return new object[] { DateTime.Now, DateTime.Now.AddMinutes(2), true };
            yield return new object[] { DateTime.Now, DateTime.Now.AddMinutes(-3), false };
            yield return new object[] { DateTime.Now, DateTime.Now, false };
        }
    }

And how do you run this test where it fails? I just tried VS 2019 Test Explorer and xunit.console and the 3 test cases all ran for me.

Since it has been like 6 months after i faced the issue, we have moved away from using StaFact library. And we fixed the tests using another approach. So I am trying to reproduce it but i am unable to do so.

OK, thanks for following up. I'll close this since we have no repro then.
