爲什麼這會在ReSharper測試運行器中顯示出MSpec行爲？

MSpec大師，爲什麼不工作？爲什麼這會在ReSharper測試運行器中顯示出MSpec行爲？

public class with_command_line_args { 
    protected const string ValidFilename = "ValidFilename.txt"; 
    protected const string InvalidFilename = "Invalid:Filename"; 
    protected static string[] Args; 
    protected static Exception Exception; 
} 

[Behaviors] 
public class InvalidCommandlineArgsBehaviours 
{ 
    protected static Exception Exception; 
    It should_throw=() => Exception.ShouldNotBeNull(); 
    //It should_not_store_any_filename; 
} 

[Subject(typeof(Program), "Invalid command line parameter")] 
public class when_invoked_with_no_parameters : with_command_line_args 
{ 
    Establish context =() => Args = new string[] {}; 
    Because of =() => Exception = Catch.Exception(() => Program.ProcessCommandLineArgs(Args)); 
    Behaves_like<InvalidCommandlineArgsBehaviours> invalid_args; 
}

，當我在ReSharper的運行它，規格顯示出來，但不執行（我也不能對它進行調試）：
ReSharper Unit Test Runner output
奇怪的是，被註釋掉的規格在ReSharper的顯示出來輸出。嗯？顯然我沒有做正確的事，請賜教！
