SonarQube: Unit Test Results Not Shown

Recently whilst building Jenkins CI pipeline, with SonarQube static analysis, the JUnit unit test results were not being included in the Sonar dashboard results. The Jacoco based test coverage results were being included fine but not the actual test pass/fail percentage.

After digging into the log for the Jenkins build I found this warning being logged for the SurefireSensor (the Sonar sensor responsible for scanning JUnit XML reports for results):

[sonar] 10:26:34.534 INFO - Sensor SurefireSensor
[sonar] 10:26:34.534 INFO - parsing /apps/jenkins2/var/lib/jenkins/workspace/abc/code\_master/examplecode/UnitTest/junit
[sonar] 10:26:34.864 DEBUG - Class not found in resource cache : com.rh.examplecode.UIMapperTest
[sonar] 10:26:34.864 WARN - Resource not found: com.rh.examplecode.UIMapperTest

The JUnit XML reports were being found and parsed fine but when it’s looking for the actual test code (the *.java code) it could not be found by the scanner and hence it throws the warning. It turns out that the java code for the tests is required in order analyse the JUnit results files and so you need to tell Sonar where to find the source code for the tests. How? Well this is done via the sonar.tests” property which is a comma-separated list of filepaths for directories containing the test code (the *.java files not *.class files). For example:

sonar.tests = “/UnitTests/junit”

Set this property alongside the other parameters for Sonar, for example:

1
2
3
4
5
6
7
8
9
10
sonar.projectBaseDir="${WORKSPACE}/exampleApp"
sonar.projectKey="testbuild1"
sonar.projectName="testBuild"
sonar.sourceEncoding="UTF-8"
sonar.sources="src/main/java/com/rh/examplecode/"
sonar.junit.reportsPath="ReportsXML/"
**sonar.tests= "/UnitTests/junit"**
sonar.jacoco.reportPath="target/jacoco.exec"
sonar.jacoco.reportMissing.force.zero="true"
sonar.binaries="build/com/rh/"

After this change the Sonar scanner will run and this time find the test source code, enabling it to complete the analysis. The log should report something like this:

1
2
3
[sonar] 13:10:20.848 INFO - Sensor SurefireSensor
[sonar] 13:10:20.848 INFO - parsing /apps/jenkins2/var/lib/jenkins/workspace/abc/code\_master/ReportsXML
[sonar] 13:10:21.022 INFO - Sensor SurefireSensor (done) | time=10ms

And you should now have your unit test success/failure results in your unit test widgets in the projects Sonar dashboard, like so:
