Answer 1

I see that you are using Eclipse, but are you also using some other external build/test tool like Ant or Maven? Sometimes Eclipse can get out of sync when also using other external tools.

If you are using external tools, do whatever is necessary to clean up generated artifacts (e.g. mvn clean). Then refresh the Eclipse project and do a clean build as suggested previously. Then try running your unit test again using Eclipse.

Good luck and hope this helps.
