public class RunnableInDebugOnlyAttribute : FactAttribute
{
    public RunnableInDebugOnlyAttribute()
    {
        if (!Debugger.IsAttached)
        {
            Skip = "Only running in interactive mode.";
        }
    }
}

//// After that just use the attribute `RunnableInDebugOnlyAttribute` instead of `Fact` when you want the test to be ignored in automatic runs without debug, for example
// Example of method in test suite
// [RunnableInDebugOnlyAttribute()]
// public void Test()
// {
      // Runs only in debug mode
// }
