During suite tests EasyMock says 0 matchers expected 1 recorded

Question

So I\'ve been using EasyMock\'s class extension for a while now. All of a sudden I\'m getting this exception, but only when I run the entire test suite:

java.lan

I was sick and tired of seeing this with each new legacy code base with EasyMock I had to work with. Write one new EasyMock test by the book and all of the sudden random tests start failing because of Matchers never captured. So I went looking how EasyMock stores those Matchers. It makes use of a final class LastControl, in that class are a few threadlocals where different things get stored. One of those was for the Matchers. Luck has it that there is a static method on there to pull all the Matchers from the threadlocal that where still on there. So this gave me this idea (with help of a collegue, thanks Sven, he wanted credit)

/**
 * Base class to make sure all EasyMock matchers are cleaned up.  This is not pretty but it will work
 * 
 * @author N069261KDS
 *
 */
public class BaseTest {

  @Before
  public void before(){
    LastControl.pullMatchers();
  }

  @After
  public void after(){
    LastControl.pullMatchers();
  }

}

Basicly let your test that fail with the Matchers error extend from this class and you'll be sure the Matchers are cleaned. Note this IS A WORKAROUND. The offending tests should have been written right in the first place. But if you have to wade through 5000+ tests , this is the lesser of two evils. I hope this will help people out !
