I am looking for a code coverage tool, which helps me find coverage of selected packages in my workspace.
Solution pertaining to CI or Eclipse is welcome.
I am aware that, I can manually calculate based off the numbers I get from code coverage tools in eclipse. But I am reluctant to do so and want to rely on automatically computed code coverage.
Please help.
You could try the google CodePro,

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.
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.
In Intellij Idea after running tests with coverage I don't see color indicators in the editor. I tried different code coverage tools (Intellij, Emma, JaCoCo), but result is the same. On clean project setup everything works.
Does it needs to be additional configured or it's a bug in Idea?
I'm using IntelliJ IDEA 14.1.4 Ultimate.
It's a bug in IDEA, so you should report it.
Be sure to include enough information to reproduce the problem. In your case, make a copy of your project and repeatedly remove irrelevant files, until you finally come to a point where everything works.
I just installed ecobertura plugin, but it looks like not a very user-friendly tool from within eclipse. is there any good plugin for cobertura in eclipse or article to describe how to use ecobertura?
I'm used to seeing code complexity and coverge etc in a very nice way.
I need to use cobertura, because the build system in the back-end uses it, so it makes sens to use it in the IDE as well.
Regards
I was looking for a tutorial for our team members to start using eCobertura and came across here. I end up writing one myself. Posting back here hope it may help others looking for a jump start.

From the sources:
there should be launch configuration's "filters" tab, for you to define what class to filter and analyze: see changeset 2ecbb202e8c5
there is no instances of "cyclomatic complexity" anywhere in the code.
But you still can fork the code base (like mileszk did) and add any feature you want (and contribute back to the main project of course ;) )
I am using Eclipse Luna and I had difficulty installing the ecobertura plugin. So I installed EclEmma plugin and it was intitutive to use it. After installing the plugin, restart the eclipse IDE.
To find the coverage of the test cases you have written, all you have to do is
Right click on the desired package or even the whole project > Coverage As > Junit Test
The Coverage View automatically appears. Or you can open the coverage view from Window > Show View > Other > Java > Coverage. Or you can just type "Coverage" in the Quick Access search box in the eclipse.
The Coverage view is capable of displaying the coverage percentage at project level, source folder level, package level, Class level and even at method level.
You can change the root level of the entries shown in the coverage tree by using the toolbar in the coverage view.
You can change the coverage parameters to method or Line or instruction or brach based on your requirement.
And finally you can export the test coverage results to HTML or XML or CSV formats by right-clicking anywhere inside the coverage view and selecting Export session.
