问题
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?
回答1:
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
回答2:
When you add the class to PowerMockito annotation @PrepareForTest for the test classes, the corresponding class will not be showing the code coverage.

"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.
