Android Testing: Instrumentation run failed due to 'java.lang.ClassNotFoundException'

Question

I have 3 test classes for a particular package from my main application. My first test class is running just fine, the other 2 aren't.

When I try to run those 2 tests, I get the following error:

Instrumentation run failed due to 'java.lang.ClassNotFoundException'

I already verified:

Any guess about what the problem is?

-----//-----

Solution:

I changed the version of jUnit I was using and the tests perform as they should.

You need to add JUnit library to your package as following:

On Eclipse, right click on your test project, choose Properties --> Java Build Path, on Order and Export tab, please check on JUnit 4 and click OK.

After that, clean or rebuild your test project and run.

Java build path should export JUnit 4 library(checked) and Ensure you clean and rebuild the project

have you define your other two class in "AndroidManifest"

In my target project or in my test project? The target already has those classes in its Manifest.
