Run applies template method a subclass can

TestCase.run() applies Template Method
A subclass can selectively override these methods; if it overrides only runTest , for
example, there will be no special setUp or tearDown behaviour.

TestCase: runTest()
A given test case class may implement many different methods, each defining a single
test case.
–Each test case has a descriptive name like testAdd or testRemove.
–The test cases don’t conform to a simple command interface.
Our next problem is make all the test cases look the same from the point of view of the
invoker of the test.

Adapter pattern springs to mind.
Adapter has the following intent "Convert the interface of a class into another interface clients
expect".
