I've just added Meziantou.Xunit.ParallelTestFramework to several of my unit test projects (.NET Core 3.1), and am running them with dotnet test. Before the Meziantou.Xunit.ParallelTestFramework add, no odd messages from dotnet test; after add, I get a significant number of:

[xUnit.net 00:03:00.26] CoreApi.Tests: Result reported for unknown test case: CoreApi.Tests.ManualOpsControllerTests.FilterStationsForDiagnosticsTest(addressInt: 372230, suspended: null, channel: 2, terminal: 0, includeSatellite: False, filterSuspended: False, filterNotConnected: True)

-like messages, each for a different test instance. The tests are passing but the extra text in the build/test log is confusing/concerning. I haven't checked them exhaustively but they all seem to be xUnit tests using [Theory] and [MemberData(nameof(FilterDataGenerationMethod))].

Should I be worried? What can I do to help resolve this?

Update #1:

Yes, here are some of the details I can share:

• Declaration of the test:

    [Theory]
    // We have 7 parameters that we want to test in combination:
    // Address - basically valid and invalid (0)
    // Suspended - three values: true, false, null (should be treated as false)
    // Channel - four value types: < 0, = 0, > 0, and null (treated as 0)
    // Terminal - three value types: < 0, = 0, > 0
    // IncludeSatellite - whether the Station.Satellite value is set to the satellite when call is made - true/false
    // FilterSuspended - whether to filter suspended stations from the incoming list (true), or not (false)
    // FilterNotConnected - whether to filter not-connected stations from the incoming list (true), or not (false).
    // We generate this data using the xUnit MemberData attribute.
    [MemberData(nameof(GenerateFilterData))]
    public async Task FilterStationsForDiagnosticsTest(int addressInt, bool? suspended, int channel, short terminal,
        bool includeSatellite, bool filterSuspended, bool filterNotConnected)

• Method generating test data:

    /// <summary>
    /// Generate the test data, as an enumerable of object arrays, to match the desired filter tests:
    /// We have 7 parameters that we want to test in combination:
    /// Address - basically valid and invalid (0)
    /// Suspended - three values: true, false, null (should be treated as false)
    /// Channel - four value types: < 0, = 0, > 0, and null (treated as 0)
    /// Terminal - three value types: < 0, = 0, > 0
    /// IncludeSatellite - whether the Station.Satellite value is set to the satellite when call is made - true/false
    /// FilterSuspended - whether to filter suspended stations from the incoming list (true), or not (false)
    /// FilterNotConnected - whether to filter not-connected stations from the incoming list (true), or not (false).
    /// </summary>
    /// <returns></returns>
    public static IEnumerable<object[]> GenerateFilterData()
    {
        List<object[]> testObjects = new List<object[]>();

        // Generate an AddressInt value.
        foreach(int addressInt in new int[] { 0, 0x5ae06 })
        {
            foreach(bool? suspended in new bool?[] { null, false, true })
            {
                foreach(int? channel in new int?[] { null, -2, 0, 2 })
                {
                    foreach(int terminal in new int[] { -3, 0, 3 })
                    {
                        foreach(bool includeSatellite in new bool[] { false, true })
                        {
                            foreach(bool filterSuspended in new bool[] { false, true })
                            {
                                foreach(bool filterNotConnected in new bool[] { false, true })
                                {
                                    testObjects.Add(new object[]
                                    {
                                        addressInt, suspended, channel, terminal, includeSatellite, filterSuspended, filterNotConnected,
                                    });
                                }
                            }
                        }
                    }
                }
            }
        }
        return testObjects;
    }

Update #2

Thanks for the type tip. Reviewing the generated data found that I was passing an int rather than a short for "terminal". Correcting that corrected the issued. Much appreciated!
