@ParameterizedTest with @MethodSource doesn't work with gradle plugin

[St4rG00se]

@ParameterizedTest with @MethodSource are ignored with gradle plugin

How to reproduce :

Get this MAVEN project : https://github.com/dmitry-timofeev/pitest-with-junit5-issue/tree/master

Update CalculatorTest file

class CalculatorTest {

  @ParameterizedTest
  @MethodSource("args")
  void increment(int i, int expectedResult) {
    assertEquals(expectedResult, Calculator.increment(i));
  }

  public static Stream<Arguments> args(){
    return Stream.of(
        Arguments.of(1,2),
        Arguments.of(2,3)
    );
  }

}

Maven check:

• UPDATE pitest version (pitest-maven: 1.6.2 / pitest-junit5-plugin: 0.12)
• Run mvn clean package org.pitest:pitest-maven:mutationCoverage
• IT WORKS (See: 'Tests examined' in 'Calculator.java.html' is filled)

Gradle check

• Insert the following build.gradle file to the project :

  
  plugins {
  id 'java'
  id 'info.solidsoft.pitest' version '1.5.2'
  }

repositories { mavenCentral() }

dependencies { // JUNIT testCompile group: 'org.junit.jupiter', name:'junit-jupiter', version: "5.7.0" }

pitest { testSourceSets = [sourceSets.test] targetClasses = ['dt.pitest.'] targetTests= ['dt.pitest.'] junit5PluginVersion = "0.12" pitestVersion = "1.5.2" testPlugin = "junit5" threads = 1 outputFormats = ['XML', 'HTML'] timestampedReports = false }

test { useJUnitPlatform() }

- Run `./gradlew clean build pitest`
- IT FAILS (See: 'Tests examined' in 'Calculator.java.html' is **empty**) 

Notes:
- It works with @Test or @CsvSource
- Gradlew version: 6.7

Thank for your answer

It should work. Have you tried with the junit-jupiter-params dependency added also in the Gradle project?

Update. I confused org.junit.jupiter:junit-jupiter-engine with org.junit.jupiter:junit-jupiter. The later pulls in also junit-jupiter-params (I wonder why you did it manually with Maven?).

In general thanks for the sample project which helps to reproduce the issues. With build.gradle (and Gradle wrapper) in place it would be even simpler, but I copy-pasted your content and it seems to work as expected:

$ ~/.gradle/wrapper/dists/gradle-6.3-bin/.../gradle-6.3/bin/gradle pitest
Starting a Gradle Daemon (subsequent builds will be faster)

Update. The same result with Gradle 6.7

Btw2, you can remove:

    junit5PluginVersion = "0.12"
    pitestVersion = "1.5.2"

from your configuration. For the Gradle plugin 1.5.2 they are the default values.

@St4rG00se As I wasn't able to reproduce the problem with your project, I wonder if you're still facing that problem?

[St4rG00se]

I don t reproduce it again...

sorry and thank you for your time
