pitest doesn't find tests

问题

I am facing a problem with the SonarQube project. I want to calculate some statistics about test quality and I am using pitest. Unfortunately, it doesn't find any test to mutate.

This is the pom.xml of the module that I am analyzing:

But when I run:

mvn clean install org.pitest:pitest-maven:mutationCoverage

it doesn't find tests, namely:

4:16:26 PM PIT >> INFO : Sending 0 test classes to minion
4:16:26 PM PIT >> INFO : Sent tests to minion
4:16:27 PM PIT >> INFO : MINION : 4:16:27 PM PIT >> INFO : Checking environment

4:16:27 PM PIT >> INFO : MINION : 4:16:27 PM PIT >> INFO : Found  0 tests

4:16:27 PM PIT >> INFO : MINION : 4:16:27 PM PIT >> INFO : Dependency analysis reduced number of potential tests by 0

4:16:27 PM PIT >> INFO : MINION : 4:16:27 PM PIT >> INFO : 0 tests received

PS: the tests in maven are correctly executed:

Results :

Tests run: 402, Failures: 0, Errors: 0, Skipped: 0

What am I wrong?

回答1:

You specified for the pitest plugin

<targetClasses>
  <param>org.sonar.core.*</param>
</targetClasses>
<targetTests>
  <param>org.sonar.core.*</param>
</targetTests>

Did you check, you have test classes in those packages?
