Can I use Cobertura on Unit Tests with PowerMock?

Problem

I am setting-up unit-test code coverage for an Android library which uses Robolectric to run the tests and PowerMock/Mockito for mock-testing.

However, running unit-tests with Cobertura results in the following Exception...

:example:testDebugUnitTest

...and the generated Cobertura report shows no coverage at all. Cobertura report with PowerMock


Running the same testcase without PowerMock*, the tests run fine and the coverage report is generated successfully: Cobertura report without PowerMock

​* i.e. commenting the tests using PowerMock, removing the PowerMockIgnore annotation, the PowerMockRule and the MockitoAnnotations.initMocks(this); invocation.


Investigation


Question

Is it possible to use Cobertura in conjunction with PowerMock?

  • In that case, what am I missing?
  • Otherwise, how should I measure code coverage with such a setup (Android Library + Robolectric + PowerMock)?

Right now, Android Studio integrates jacoco automatically to do code coverage.

You just need to add a few lines of code:


apply plugin: 'jacoco-android'

android {
buildTypes {
debug {
testCoverageEnabled = true
}
}
}
