// OCUnit/SenTestCase's vanilla testInvocations method does not produce a unique list of methods
// when you inherit from a common test base class.  Currently it will call the same test methods
// multiple times, depending on the number of base classes.
//
// To prevent these duplicate test method calls, override testInvocations like this.
