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: if the build path was properly configured, if the target package is correct, if I had problems with importing jUnit. Any guess about what the problem is? -----//----- Solution: I changed the version of jUnit I was using and the tests perform as they should.

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

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.
