Why is the xUnit Runner not finding my tests

Question

I have a xUnit.net Test as follows:

static class MyTestClass
{
    [Fact]
    static void MyTestMethod() 
    {
    }
         


        

Answer 1

I've been having this issue with .NET Core for a while now where a test class or a test method is not being discovered. The following fix works for me:

1. Open a command prompt window.
2. Change to the project directory.

3. Build the project running the following command:

   dotnet build
   

NOTE: Building from Visual Studio.NET will not work! <<<<<<<<<<< IMPORTANT!

4. Run the tests: Test --> Run --> Test All - CTRL+R +A (this will discover the new test(s) - but not run the the new test(s).
5. Run the tests again.
