Unable to get Jacoco to work with Powermockito using offline instrumentation

Question

Given that Jacoco doesn\'t play nicely with PowerMockito when instrumenting \"on the fly\", I\'ve been trying to configure offline instrumentation in the hope this will give

Answer 1

I was also facing the same issue. I was able to generate report partially. I have used both these tags for my test cases @RunWith(PowerMockRunner.class) @PrepareForTest({}). And the report was not getting generated for the test cases where i used the above mentioned tags. But for one of the test case there was only this tag @RunWith(PowerMockRunner.class). Somehow the report was getting generated for that case. And also i have never used offline instrumentation. When i tried using the offline instrumentation i was getting error saying that the class was already instrumented. I tried various scenarios and followed various links but could not generate the report. Finally as per the above comment i upgraded my version of powermock from 1.5.5 to 1.6.5 and i was able to generate the report. Following is my pom.xml entry

     
    org.jacoco
    jacoco-maven-plugin
    0.7.5.201505241946
    
        
            pre-unit-test
            
                prepare-agent
            
             
                    
                    ${basedir}/target/jacoco.exec
                    
            
        
        
            
            default-report
            verify
            
                report
            
              
                
                ${basedir}/target/jacoco.exec
                
                ${basedir}/target/jacoco-ut
            
        
    

Following is my entry in pom .xml for maven-surefire-plugin

    
        org.apache.maven.plugins
        maven-surefire-plugin
      
            @{argLine}
            false
            true
        
    

@{argLine} was set as a property

    -noverify -Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m

And upgraded my powermock version from 1.5.5 to 1.6.5 . Finally i could see my report generation for the classes where i used the following tags in my test cases @RunWith(PowerMockRunner.class) @PrepareForTest({})
