In Eclipse with jacoco, I can get branch coverage percentage.
But in IntelliJ IDEA, I can only get lines&method coverage percentage in coverage window.
How to summarize branch coverage in IntelliJ IDEA?
In IntelliJ to add "branch coverage" to the coverage window, you can go to Run/EditConfiguration then proceed to Modify options/coverage setting and enable use tracing.
Here is an example
First, by default intellij not showing the branch coverage inside Coverage window.
Personally, I think it is better to show it by default.
So if you are interested in "branch coverage", you need to activate its config Use tracing.
You have 2 options:
Set the config "Globbaly" for all tests:
You can change the template of RUN/DEBUG config by follow the below steps:
Set the config "Custom" for one test RUN/DEBUG config:
You can change the cutom of RUN/DEBUG config for a partuiclar test by follow the below ste:

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 see that the build-in code coverage in Intellij is pretty minimal (only include line coverage, and not branch coverage).
What are the recommended code coverage libraries to work with IntelliJ?
(I used to work with Jacoco in Eclipse).
The IntelliJ IDEA code coverage runner provides branch coverage.
Tracing mode enables accurate collection of the branch coverage, with the ability to track tests, view coverage statistic, and get additional information on each covered line.
(From the docs)
To engage this, open the Edit Run/Debug Configuration dialog box for your test run and click on the Code Coverage tab. Then ...
Chose coverage runner: IntelliJ IDEA
Click on Tracing (instead of the default: Sampling)
Run your test and then click into the class from the Coverage Window and you'll see branch information in the side bar.
Here's a screenshot:
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
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 configured EclEmma not to instrument my unit tests which works fine. However, the editor still highlights the test code as not covered. I want no highlighting in unit tests because they are not instrumented to detect coverage. How can I do this?
I did the following steps:
Go to Preferences->Java->Code Coverage and
set the "Only path entries matching" option to src/main/java
It seems to work nicely.
The include/exclude filter settings in the Preferences window apply to class name/package patterns for all projects. To control the files at the folder/path level you must set it per-project.
Right-click the project
Select Coverage As | Coverage Configurations...
Select the project under the Junit subtree
Select the Coverage tab on the right
Uncheck the folder containing your tests, e.g., src/test/java
Click Apply
Click Close (or Coverage to run immediately)
These settings will apply every time you run the coverage in the future without having to open the configuration window.
