NullReferenceException when getting TestDirectory from TestContext

[florian-gandon]

Hello !

In the context of an attribute implementing ITestAction applied at assembly level, I'm receiving NullReferenceException when calling TestContext.CurrentContext.TestDirectory in AfterTest method.

I've provided a project as a sample.
ClassLibrary22.zip

As work around, I'm doing:
AssemblyHelper.GetDirectoryName(Assembly.GetCallingAssembly())

Is there another way to get the test directory at this moment ?

Regards,
Florian

This line of code in TestContext.cs is at fault:

                    return AssemblyHelper.GetDirectoryName(test.TypeInfo.Assembly);

Use of TypeInfo implies that the test is implemented by a method or class. That's true for everything except the top-level assembly. We can either add special code to detect that it's a test assembly and cast in order to get the Assembly or - even simpler - arrange to fall through to the following code that uses GetCallingAssembly.

Thanks for the quick answer and the fix.
