pitest not able to locate junit test

Question

My gradle pitest is not able to give me the right results. It looks like it is not able to locate my test files.

I have the following build.gradle file:

apply plugin: "java" apply plugin: "maven" apply plugin: "info.solidsoft.pitest"

group = "myorg" version = 1.0

repositories {
    mavenCentral() }

sourceSets.all { set ->
    def jarTask = task("${set.name}Jar", type: Jar) {
        baseName = baseName + "-$set.name"
        from set.output
    }

    artifacts {
        archives jarTask
    } }

sourceSets {
    api
    impl    main{       java {          srcDir 'src/api/java'           srcDir 'src/impl/java'      }   }   test {      java {          srcDir 'src/test/java'      }   } }

buildscript {
    repositories {
        mavenCentral()
        //Needed only for SNAPSHOT versions
        //maven { url "http://oss.sonatype.org/content/repositories/snapshots/" }
    }
    dependencies {
        classpath 'info.solidsoft.gradle.pitest:gradle-pitest-plugin:1.1.6'
    } }

dependencies {
    apiCompile 'commons-codec:commons-codec:1.5'

    implCompile sourceSets.api.output
    implCompile 'commons-lang:commons-lang:2.6'

    testCompile 'junit:junit:4.9'
    testCompile sourceSets.api.output
    testCompile sourceSets.impl.output
    runtime configurations.apiRuntime
    runtime configurations.implRuntime }

jar {
    from sourceSets.api.output
    from sourceSets.impl.output }

pitest { println sourceSets.main

    targetClasses = ['doubler.*']       targetTests  = ['doubler.*']    verbose="on" }

THe output is stored in the correct folder. And when I run gradle test, it also runs fine.

Some additional information about this issue was supplied in the pitest user group.

https://groups.google.com/forum/#!topic/pitusers/8C7BHh-Vb6Y

The tests being run look like this.

@Test
public void testIt2() {
    assert new DoublerImpl().testIt(1) == 2;
}

Pitest is correctly reporting that these tests provide 0% coverage of the class. There is no coverage because the assert keyword has been used.

Unless the -ea flag is set in the JVM running the tests assertions are disabled. There is basically hidden if block around this code generated by the compiler

@Test
public void testIt2() {
    if (assertionsEnabled) {
      assert new DoublerImpl().testIt(1) == 2;
    }
}

As assertions are not enabled no code is executed.

To fix the issue use the built in JUnit assertions instead.
