As discussed in Open JaCoCo report in Intellij IDEA, when I gather code coverage statistics using Jacoco (rather than native IntelliJ tracing) 0.0% (i.e. "no" coverage) is always shown in the coverage window.
This is after I have done the whole "Analyze -> Show coverage data..." and selected my generated "jacoco.exec" file.
The same "jacoco.exec" file works fine with other tools such as the Jacoco native report generation task, and with Sonar, and these produce the expected coverage report content.
Also native IntelliJ instrumentation works fine.
Can anybody advise me if there is some essential step I must perform to get IntelliJ to accept my Jacoco coverage?
When you add the class to PowerMockito annotation #PrepareForTest for the test classes, the corresponding class will not be showing the code coverage.
Buid source code through IntelliJ before importing jacoco.exec might be solved this showing 0% coverage problem.
For me the solution was to simply add the root package (in my case "de" in your case probably "com") to the "Packages and classes to include in coverage data".
Now i see a reasonable Code Coverage.
I may guess you are trying to see test coverage in same way as it is show by the TeamCity(jaCoCo).
If Yes there are simple workaround how to check all missed branches(just general statistic which branches was visited and how many times) :
That's all my advices , folks
"intellij idea" seems to have no way of showing correct coverage value of jacoco report created. It is indeed misleading and unfair when it shows coverage as 0.0 instead of giving an unsupport format error.
However, as an alternative, we can push jacoco report (created as part of maven build) to the sonar(qube) server using maven-sonar-plugin's target, sonar:sonar
mvn clean install sonar:sonar -Dsonar.host.url=http://<sonar-host>:9000 -Dsonar.projectKey=<sonar project key> -Dsonar.branch=<sonar project branch> -Dsonar.login=<sonar user> -Dsonar.password=<sonar pwd>
sonar.projectKey and sonar.branch properties value can be retrieved from corresponding project created in sonarqube.

I have a Java program based on maven and for that I need to know the test coverage percentage. For testing, I am using testng.
I can already run the tests using command mvn test. All the tests are passing and I can see the report in surefire-reports/index.html. But I could not get the test coverage percentage that I need to supply for reporting.
mvn test
Expected result is Test Coverage Percentage is x%
You can use Intellij to get a coverage report. Right-click on a test folder: run all with coverage and here you go,
maybe you will need to call report window explicitly, it's located View -> Tool Windows -> Coverage. The last question about default plugin. The only information I can tell you about it is located in settings-> plugins:
For those Using Netbeans IDE, do the following
Right Click on the Project
Select Code Coverage
then choose Show Report
As shown Below
Code coverage for every file will be displayed.
I have a class annotated with Lombok's #Data, in a gradle project, using the Sonarqube and Jacoco plugins.
The source code is available here on github
I have a locally running sonarqube server running as a docker container, started like this:
docker run -d --name sonarqube -p 9000:9000 -p 9092:9092 sonarqube
I have added a "lombok.config" file, asking it to add #Lombok.Generated annotations to its generated code, as per the Global Config keys section here in the docs.
lombok.addLombokGeneratedAnnotation = true
And I have the following Sonar condition configuration.
When I run the sonarqube target for the very first time, it reports that the project passes.
If I then switch the lombok.addLombokGeneratedAnnotation to be false, and rerun the sonarqube target, it reports that there is a failure:
If I then switch the lombok.addLombokGeneratedAnnotation back to true, and rerun again, sonarqube reports that the project is still failed. And I can't get the project to pass again.
I then changed the group name in the build.gradle file, to force the sonarqube gradle plugin to create a new project within the Sonarqube server. When I do this, the project passes again.
I've never changed any of the source code during this process.
Please does anyone have an idea why Sonarqube is behaving this way?

Oh, but you have. Or rather, Lombok has by inserting (or not) annotations in your code.
You're using a Quality Gate that looks only at "New Code". On your first analysis, no code is new, so none of it is up for consideration. Then you twiddle your Lombok settings, regenerate and reanalyze. Lombok apparently makes some changes in your code. I've never used Lombok so I can't expand on exactly what's happening here, but you can click through on the New Coverage-related metrics on the project homepage to get to a list of files. Drill into a file to see what's being considered "new" in it (yellow highlight). Look to the marginal markings (red, green, yellow striped) to see what's considered covered.
N.B. Your quality gate currently demands 99% coverage on conditions in new code. This is unrealistic and past the point of diminishing returns. You should reconsider this value. IMO 85-95% is more realistic depending on your team.
For future reference, we found that the problem was solved by updating the SonarJava plugin to the newest 5.1.1 release.
I think this ticket in release 5.1, to upgrade to Jacoco 0.8.0 may be the thing that started to honour the #Lombok.Generated annotation.
I have written some Test methods using Junit and mockito. My tests run fine. However, I am not able to see code coverage.
No matter which option I click on, nothing is shown in code coverage.
I clicked on EDIT to fix configuration seetings displayed in middle of code coverage window on right. This is what I get :
What should I do to get code coverage results ?
This is my folder structure :
To see coverage for production code change the pattern to com.cdk.dmg.asset.
You need to Enable coverage in test folders if you want see coverage in tests (this option is disabled on your screenshot and the pattern is set to record data for tests only, hence no results).
Make sure you have the Coverage plugin enabled! (yes, it's named literally just "Coverage")
Enabling it did it for me.
You don't need to download it from Marketplace, the plugin comes bundled with IntelliJ Idea.
It's my understanding that it should be enabled by default ..but for some reason that wasn't the case for me, so it might as well not be the case for you either.
In IntelliJ IDEA 2018.3 I had to change Test Runner to Gradle to solve the same problem in my Gradle-based project.
File | Settings Ctrl+Alt+S
Build, Execution, Deployment | Build Tools | Gradle | Runner
Run tests using: Gradle Test Runner
Only then I was able to see the coverage.
This is my first answer
you can follow the below steps to enable
Open Visual studio and goto Extensions
Select Manage extension
Search fine code coverage and select to enable
you will get red and green lines on your actual methods that showing that how much you covere the code in Unit test case.
Follow steps
I have setup jacoco in jenkins as part of functional test job to generate code coverage report. But I feel its very tough to understand.
Somewhere I read that covered and uncovered lines of code are shown in colors in Eclipse. This is for functional tests which connect to a stage where the whole business logic has been deployed. This is present inside Eclipse also as part of the project. How to set it up?
What difference the setup has for unit tests?
You can download the Eclemma plugin from Eclipse marketplace.
Open Marketplace from Help menu.
Search for Eclemma Java Code Coverage.
Install and Restart Eclipse.
Right-Click on the project, select Coverage as -> JUnit Test
http://www.eclemma.org/userdoc/importexport.html mentions being able to import reports, but that they have to be exactly the same class files both when the report was generated and within the Eclipse workspace. It may work, it may not.
We have a single evosuite generated unittest .java file. We have other hand-crafted unittest .java files. We execute a build on our server and all unittests (evosuite and hand-crafted) are executed. We then go into our sonar dashboard and specifically look at the coverage. There is coverage reported by sonar/jacoco from the handcrafted unittests. However for the .java file that the evosuite was to test, that file still has 0% coverage even though on another panel in the sonar/jacoco dashboard the evosuite 16 tests were executed and it shows how long in ms they took.
The server where the builds take place was configured for us and we do not manage them. Sonar/Jacoco admin setup was done by others.
I'm at a loss as to why our handcrafted ones (some use #RunWith(JMockit.class) and some don't use a RunWith annotation) show up w/ coverage percentages and the evosuite does not.
Thanks,
Jim
yes, that is an issue that has been reported few times now... so I just added now some documentation about it :-) at:
http://www.evosuite.org/documentation/measuring-code-coverage/
you can read there why you get 0% coverage, and possible workarounds for it.
