PowerMock ECLEmma coverage issue

Question

We are using EasyMock and PowerMock with JUnit. The coverage tool used is ECLEmma. With EasyMock, it shows the coverage properly in green (as covered). However, for

Answer 1

Yes, there is a solution for this:

First you will have to add this maven dependency:

<dependency>
  <groupId>org.powermock</groupId>
  <artifactId>powermock-module-junit4-rule-agent</artifactId>
  <version>1.6.4</version>
  <scope>test</scope>
</dependency>

Then, instead of using this annotation @RunWith(PowerMockRunner.class), just add a @Rule in the Test class like this:

public class Test {

   @Rule
   public PowerMockRule rule = new PowerMockRule();

Answer 2

We have a static classes to mock. With mocking static classes, eclEmma code coverage plugin is not working in Eclipse. So what we did is, so placed @RunWith(JUnit4.class) (Instead of @RunWith(PowerMockRunner.class) ) before class and placed following lines inside class

static {
PowerMockAgent.initializeIfNeeded();
}

@Rule
public PowerMockRule rule = new PowerMockRule();

Compiled the class and ran the test class. Code coverage is working for class. This change is only in Eclipse IDE.

After writing test cases, we reverted code back to normal. Placed @RunWith(PowerMockRunner.class) instead of @RunWith(JUnit4.class) and commented above static code and powermockrule lines.
