Easymock: matcher calls were used outside expectations

You are running your unit tests with EasyMock and then you face this kind of error "matcher calls were used outside expectations".

java.lang.IllegalStateException: matcher calls were used outside expectations
at org.easymock.internal.RecordState.replay(RecordState.java:86)
at org.easymock.internal.MocksControl.replay(MocksControl.java:169)

This happens because you are having some kind of code like this, where the .andReturn is not returning an object.

To fix this, you should use the null return or return an instance of an object, or even a mock object:
expect(mockdao.bark(EasyMock.anyObject(Dog.class))).andReturn(new Noise()));
