Configure Sonar to see Integration Tests (v6.2)

Question

How to visualize Integration Tests in Sonar ?

Currently I only see :

• the global coverage (UT + IT)
• the number of UT

I read somewhere we had to configure a widget in the GUI : I didn't see any option which could do that.

Documentation states :

If coverage by unit tests is not computed with JaCoCo, overall coverage = integration test coverage.

But in my case I see that the coverage is changing when I change my UTs (or ITs). Moreover I see jacoco reports in the targets :

• jacoco.exec
• jacoco-it.exec

I finaly tryed the official Sonar samples : it is the same ! I didn't find any sample with a clear separation between :

• Unit test coverage
• Integration test coverage
• Overall test coverage

And sorry but Sonar documentation and samples have to be improved...

Context : sonar6.2, java8, spring boot, modular project, maven, surefire & failsafe

Answer 1

Starting in SonarQube 6.2, all test results are merged into simply "coverage". This was done on the theory that by and large, most people don't care how their code is covered, only that it is covered.

With this change, some math inconsistencies w/r/t how Overall Coverage was calculated from unit tests versus integration tests were eliminated, and additionally the ability to feed many different coverage reports was added. (Some people have unit, integration, smoke, ... tests).

In 6.2 dashboards were dropped, so there are no widgets to be configured. Coverage is shown automatically on the project home page.

Answer 2

Merging unit testing coverage and integration testing coverage numbers is not a good idea.

Modern unit tests that mock out all dependencies and environmental factors and have been proven to run on a developers local machine cannot by definition fail in a continuous integration environment. This makes them next to useless to run in a CI environment. Therefore, 100% unit test coverage but 0% integration test coverage means no meaningful testing is actually happening in the CI build.
