            <artifactId>pitest-maven</artifactId>
            <version>1.1.9</version>
            <configuration>
                <targetClasses>
                    <param>com.plugin.business.centre*</param>
                </targetClasses>
                <targetTests>
                    <param> com.plugin.business.centre*</param>
                </targetTests>

Answer 1

For people reaching this question with the same problem:

I was facing the same issue and I fixed it by running mvn test before Pitest.

Pitest somehow needs those tests to be executed at least one to find them.

Answer 2

Pitest can not find testPlugin automatically, set it manually:

for maven:

<testPlugin>
    <value>junit5</value>
</testPlugin>

for gradle:

pitest {
    testPlugin = "junit5" //or another test plugin
    ...
}

Answer 3

I need to add the junit5 plugin as a dependency (as I'm using JUnit 5).

<plugin>
    <groupId>org.pitest</groupId>
    <artifactId>pitest-maven</artifactId>
    <version>1.4.5</version>
    <dependencies>
        <dependency>
            <groupId>org.pitest</groupId>
            <artifactId>pitest-junit5-plugin</artifactId>
            <version>0.8</version>
        </dependency>
    </dependencies>
    <configuration>
        ...
    </configuration>
</plugin>

Answer 4

My tests weren't detected because I used Java's built-in assert, e.g.:

assert 1 + 2 == 3;

When I changed it to JUnit's:

import static org.junit.Assert.assertEquals;

assertEquals(1 + 2, 3);

PITest works as expected. I didn't dig deeper why it works this way.

Answer 5

It was not working as we migrated from Junit4 to Junit5. There is no support to Junit5 directly. The solution is to use the plugin from pitest for Junit5 Refer https://github.com/pitest/pitest-junit5-plugin

plugins {
    id 'java'
    id 'info.solidsoft.pitest' version '1.5.1'
}

pitest {
    //adds dependency to org.pitest:pitest-junit5-plugin and sets "testPlugin" to "junit5"
    junit5PluginVersion = '0.12'
    // ...
}
