My PITEST won't run. Coverage generation minion exited abnormally. I need help to configure my pom.xml properly

Question

When running mvn org.pitest:pitest-maven:mutationCoverage, I get the error as follows ( Environment: Windows 10, Maven 3.6.1, Java 11, junit-jupiter 5.4.1, pitest 1.4.7)

Answer 1

JUnit seems to be missing from dependencies, so try adding the following to pom.xml:

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

But one of the goals is to upgrade from junit to jupiter (4 to 5). – Philbert

Anyway, I tried it, even if I did not quite understand why. Well, errors disappeared! So thanks a lot! But: Can you explain me a little here? I thought that either I use 4, OR (exclusicvely) I use 5. Not both. What's going on here? – Philbert

Answer 2

I fixed JUnit 5 and "minion exited abnormally" issue by following Mr. Mkyong's example at Maven – PITest mutation testing example.

Scroll down to pom.xml section, there is a sneaky pitest-junit5-plugin dependency defined in build section of pom file:

<dependencies>
    <dependency>
        <groupId>org.pitest</groupId>
        <artifactId>pitest-junit5-plugin</artifactId>
        <version>0.8</version>
    </dependency>
</dependencies>

This is my working pom.xml for jacoco code coverage and pit-mutation in maven test phase. If you only interested in pit part feel free to remove entire jacoco plugin section from build tags.

Answer 4

To add my two cents here, I used JUnit 5 with the plugin as documented. But, I had a JUnit dependency on junit-jupiter-api and I should've been using junit-jupiter-engine.

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.7.2</version>
    <scope>test</scope>
</dependency>

Answer 5

In my case I got this error because junit vintage engine was included in the pom and no test using Junit 4 were found so I just excluded junit-vintage from spring-boot. I've also excluded junit and mockito core because I'm setting manually those dependencies with a fixed version.

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.mockito</groupId>
                <artifactId>mockito-core</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.junit.vintage</groupId>
                <artifactId>junit-vintage-engine</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
