This tutorial builds on the previous video and shows how to use .NET reflection to discover methods decorated with the custom attribute. Then it shows how to invoke those methods atomically and gather the test results and display in the Test Runner UI.
- [Voiceover] My project now has a custom attribute…and I have some tests code here in testing lib…that's choosing that attribute on this three methods.…It's time for me to write some code…that finds all the methods that's marked…with this attribute, instantiates the type…and then runs the code in the test method.…I'll put that code in my Assert method.…I create a method called Get Test Method.…Look at the return value for this method,…it's a list of method info.…
And the reflection apis, method info is a type…that has all the information about the method.…Then I'll call this Get Test Methods…from another method called Run Tests.…The idea is, inside my Assert class,…I have my Observable Collection of Unit Test Info.…I can get that information from this property.…I have a number of different kinds of tests…like Are Equal and is null and is not null,…then I have this method called Get Test.…So the test runner can call Get Test…and it'll do all the work on reflecting all the types…and calling the test methods.…
Now I can go over to my main window…
