- public abstract class Filter 
- extends java.lang.Object
The canonical case of filtering is when you want to run a single test method in a class. Rather
 than introduce runner API just for that one case, JUnit provides a general filtering mechanism.
 If you want to filter the tests to be run, extend Filter and apply an instance of
 your filter to the Request before running it (see 
 JUnitCore.run(Request). Alternatively, apply a Filter to 
 a Runner before running tests (for example, in conjunction with 
 RunWith.
