I was using android mock uptil now, and faced no trouble after I set it up properly (that did take a while though).

However, I switched to a new workspace, and am facing problem with tests that were earlier passing.

Tests which mock java.lang.* or android.os.* are failing, but those which mock my classes are passing.

I have ensured that I have the android.jar file (for version 15) in androimocks classpath. I am running the test on android 7, though.I have tried restarting Eclipse, cleaning projects, closing projects etc.

Any suggestions?

From Android JUNIT test run:

java.lang.RuntimeException: Could not find mock for java.lang.Thread -- Make sure to run the MockGenerator.jar on your test jar, and to build the Android test APK using the modified jar created by MockGenerator
