Test Class Inheritance

[Filip]

Hi 

I have multiple Children tests that are executed as 'test-as-step' by parent test. Since all children override the same method OnAfterTestCompleted from BaseWebAiiTest I decided to remove redundancy by introducing new class:  

public class TestStep : BaseWebAiiTest
{
        public override void OnAfterTestCompleted(TestResult result)
        {
            // My custom code goes here
            base.OnAfterTestCompleted(result);
        }
}

  Then I updated all my children tests to inherit from TestStep class rather than directly from BaseWebAiiTest. The solution builds fine but when the tests executes and Parent tries to run any of the Children the following Exeption is thrown:  

Error attempting to execute a Test As Step. Details:
System.ArgumentException: String cannot have zero length.

Hello Filip,

Instead of trying to override BaseWebAiiTest I recommend you create your own test extension dll as documented here, which includes an OnAfterTestCompleted function.

All the best,
