android.test.InstrumentationTestRunner Class Not Found [duplicate]

Question

When trying to run an android test case I get the following last two lines:

[2013-04-22 17:11:10 - ProjectTest] Launching instrumentation android.test.InstrumentationTestRunner on emulator-5554
[2013-04-22 17:11:12 - ProjectTest] Test run failed: Instrumentation run failed due to 'java.lang.ClassNotFoundException'

I believe I need to include a jar into my build path. Any idea of which jar I need to include?

I guess you should have researched bit on internet or searched on Stackoverflow. There is a similar problem statement in the Stackoverflow: Test run failed: Instrumentation run failed due to 'java.lang.ClassNotFoundException'
