No coverage in 'all classes in scope' in Intellij

Question

In Intellij IDEA 14.1.5 Community edition, I imported maven to get coverage from jacoco.exec file. Steps followed

1. right click on imported module.

2. select Analyze-->Show Converage Data.

3. provided valid jacoc.exec file and click 'show selected'

Instead of coverage i'm getting error as no coverage in 'all classes in scope'

can anybody suggest what is wrong?

Answer 1

I had the same thing happen to me.

I was able to fix this by going to "Edit Configurations", to the "Code Coverage" tab.

I'm not sure what caused it, but the wrong package namespace was listed there. I updated the entry there and my subsequent test run with code coverage succeeded.

Answer 2

It happens if your test class and class to test are in different package structures.

My test class was in:

com.tools.api

Class to be tested was in:

com.tools.ws

Once I've corrected the pattern as com.tools.* in the code coverage tab, I was able to see coverage results.

Answer 3

I had the same problem and found solution here.

In the Code Coverage tab, define the following options:

Specify the scope to measure code coverage for. Do one of the following: To specify a class, click the Add Class button.

To specify a package, click the Add Package button.
