code coverage is 0% on offline instrumentation

[prave...@ebay.com]

Hello,

When I use powermock in unit testing, coverage is 0% and I can find my classes in the session file generated with an ID but they are not linked. Both on the fly and offline instrumentation did not work. If i don't use powermock, i see code coverage. Really appreciate your help on this.

Version

Powermock : 1.7.0RC2

Easymock : 3.4

mockito : 2.4.0

jacoco : 0.7.7.201606060606

Removed javassist dependency from my pom

Hello, 

Could you provided code example? I can guess what code doesn’t have coverage in report, because code mocked and is not called.

Thank you Arthur for looking in to this issue. I have coverage working for my project in the below configuration. So I don't think there is any issue with the code.

Powermock : 1.6.2

Easymock: 3.3.1

Mockito: 1.10.19

Jacoco: 0.7.2.201409121644

Coverage Plugin on Jenkins: 1.0.19 https://wiki.jenkins-ci.org/display/JENKINS/JaCoCo+Plugin

Latest version of Jacoco Plugin (2.1.0) on Jenkins does not support old version of reports, which is the primary motivation for me to update the plugins.

However, here is a code sample. 

@RunWith(PowerMockRunner.class)

@PrepareForTest({Classtobemocked1.class, Classtobemocked2.class})

public class ClassTests {

@Test

public void test1() {

Classtobemocked1 mock = PowerMockito.mock(Classtobemocked1.class);

PowerMockito.when(mock.getCount()).thenReturn(10);

}

}

Sorry I am not allowed to share the actual code.

Once I upgraded the versions as stated in the first post, i started getting few errors due to Mockito API

1. Mockito.spy() works only on mock objects (Fix: Spy on an instance)

2. Class xxx is not prepared for test. (Fix: add appropriate classes to @PrepareForTest)

Thanks,

Praveen
