Hi,

I'm getting the following error for a blazor project using MSTest2 using JustMock flite.

Message: 
    Test method vx.test.TestsWeb.TestSystemSetup.All_12_Cards_are_found threw exception: 
    System.TypeInitializationException: The type initializer for 'Telerik.JustMock.Core.Context.MockingContext' threw an exception. ---> System.InvalidOperationException: Some attribute type among Xunit.FactAttribute, xunit.core,Xunit.TheoryAttribute, xunit.core not found.
  Stack Trace: 
    HierarchicalTestFrameworkContextResolver.CreateAttributeMatcher(String[] attributeTypeNames)
    HierarchicalTestFrameworkContextResolver.AddRepositoryOperations(String[] attributeTypeNames, Func`2 getKey, Func`3 isInheritingContext, Boolean isLeaf, Boolean isUsedOnAllThreads)
    HierarchicalTestFrameworkContextResolver.SetupStandardHierarchicalTestStructure(String[] testMethodAttrs, String[] testSetupAttrs, String[] fixtureSetupAttrs, String[] assemblySetupAttrs, FixtureConstuctorSemantics fixtureConstructorSemantics)
    XUnit2xMockingContextResolver.ctor()
    MockingContext.cctor()

    ProfilerInterceptor.GuardInternal[T](Func`1 guardedAction)
    Mock.Create[T]()
    TestSystemSetup.All_12_Cards_are_found() line 25

 

From the following code:

    [TestClass]
    public class TestSystemSetup : Bunit.TestContext
    {
        [TestMethod]
        public void All_12_Cards_are_found()
        {
            // Syncfusion setup
            JSInterop.Mode = JSRuntimeMode.Loose;
            Services.AddSyncfusionBlazor();

            // Arrange
            IApplicationConfigurationSingleton ApplicationConfigurationSingletonMockObj = Mock.Create<IApplicationConfigurationSingleton>();
            Mock.Arrange(() => ApplicationConfigurationSingletonMockObj.Branding_Button_Background_Color).Returns("0xffff");
            Mock.Arrange(() => ApplicationConfigurationSingletonMockObj.Branding_Button_Border_Color).Returns("0xffff");
            Mock.Arrange(() => ApplicationConfigurationSingletonMockObj.Branding_Button_Color).Returns("0xffff");
            Mock.Arrange(() => ApplicationConfigurationSingletonMockObj.IsLicenceExpired).Returns(false);
            Mock.Arrange(() => ApplicationConfigurationSingletonMockObj.DaysValidity).Returns(10);
            Services.AddSingleton<IApplicationConfigurationSingleton>(ApplicationConfigurationSingletonMockObj);

            ISystemSetupRepository SystemSetupRepositoryMockObj = Mock.Create<ISystemSetupRepository>();
            Mock.Arrange(() => SystemSetupRepositoryMockObj.GetMenuSummary()).Returns(Task.FromResult(GetSummary_DataSet()));
            Services.AddSingleton<ISystemSetupRepository>(SystemSetupRepositoryMockObj);

            // Act
            IRenderedComponent<SystemSetup> cut = RenderComponent<SystemSetup>();

            // Assert all 12 cards are found
            cut.Find("#Software_licence");
            cut.Find("#Audit_Log");
            cut.Find("#Snapshots");
            cut.Find("#User_Authentication");
            cut.Find("#Source_Of_User_Information");
            cut.Find("#Application_Parameters");
            cut.Find("#Attachments");
            cut.Find("#Data_Export_Profiles");
            cut.Find("#Email_Settings");
            cut.Find("#Custom_Help");
            cut.Find("#Splunk_Settings");
            cut.Find("#ServiceNow_Settings");
        }

}

 

A bit puzzled as to why the error references xunit.

Hello Michael,

On startup, JutsMock tries to identify which of the supported test frameworks is being currently in use by querying some types in the app domain. Most probably some of the xunit assemblies were partially resolved and this causes this false alarm. Please check the build target directory for leftovers.

Updating the mstest and bunit nuget packages to the latest versions resolved the issue.

Nice catch Michael! It would be good to know which versions were causing this issue!
