ITestCaseBuilder
The ITestCaseBuilder interface is exposed by a class that knows how to
            build a test from a specified method, possibly containing child test cases.
            
                
Builds a single test from the specified method and context,
            possibly containing child test cases.
            
Examine the method and determine if it is suitable for
             this builder to use in building a TestCase to be
             included in the suite being populated.
            
             Note that returning false will cause the method to be ignored
             in loading the tests. If it is desired to load the method
             but label it as non-runnable, ignored, etc., then this
             method must return true.
