[FIXED] maven + mutation test

Issue

I followed this tutorial: https://pitest.org/quickstart/maven/

jar file won't open. I have Java Version 8 Update 291.

I tried:

$ java -jar pitest-maven-1.6.7.jar
no main manifest attribute, in pitest-maven-1.6.7.jar

I followed this tutorial: https://www.baeldung.com/java-mutation-testing-with-pitest

I step 5 doesn't work for mee: mvn command exist

mvn command is not recognized as an internal or external command 'mvn' is not recognized as an internal or external command,

mvn' is not recognized as an internal or external command

Apache Maven install "'mvn' not recognized as an internal or external command" after setting OS environmental variables?

I don't have a path to Maven.

I also tried these tutorials, they are missing like key important steps:

https://dzone.com/articles/mutation-testing-covering-your-code-with-right-tes-1

these tutorials are too long and I'll probably be fast to get answer on stackoverflow:

Solution

how to actually setup mutation testing in maven

basically... follow this tutorial: https://pitest.org/quickstart/maven/

skip the installation part in the tutorial

download apache-maven-3.8.1 [or whatever is the latest version]

add the downloaded file to your path via command line:

set PATH=%PATH%;C:\Program Files\apache-maven-3.8.1\bin

this is the actual plugin you wanna add:

<plugin>
    <groupId>org.pitest</groupId>
    <artifactId>pitest-maven</artifactId>
    <version>1.6.7</version>
    <dependencies>
        <dependency>
            <groupId>org.pitest</groupId>
            <artifactId>pitest-junit5-plugin</artifactId>
            <version>0.14</version>
        </dependency>
    </dependencies>
    <configuration>
        <targetClasses>
            <param>com.my.project.*</param>
        </targetClasses>
        <targetTests>
            <param>com.my.project*</param>
        </targetTests>
    </configuration>
</plugin>

you can replace the version & my.project but make sure my.project has .*

like this:

com.your.project.*

not this:

com.your.project

afterwards, you need this dependancy:

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

from here, the tutorial is pretty gud. you can continue by running this in command line:

mvn org.pitest:pitest-maven:mutationCoverage

then you open the folder etc. etc.
