Gradle compiles but does not run TestNG tests

Question

We just started using Gradle and TestNG on our project, so I am checking whether failing any test actually fails the build. I was quite surprised to see it does not. The tes

Answer 1

It was a stupid noob mistake indeed. We are using a multi-project setup with a master project and several folders on the same level, which contain the code and the tests. The build.gradle I was using accidentally only configured the master project to use TestNG. The solution is to include the test target within the allprojects or subprojects closure. Which is explained here: What is the difference between allprojects and subprojects

So here is the working build.gradle:

def mainClassName = 'nl.xillio.contentplatform.view.Run'


// Load settings for all projects including master and subprojects
allprojects {
    apply plugin: 'java'
    apply plugin: 'eclipse'

    version '0.1'

    repositories {
        mavenCentral()
        maven {
            url 'http://mvnrepository.com/maven2'
        }
        maven {
            url 'http://download.java.net/maven/2'
        }
    }
}

// Load the dependencies for all subprojects (layers)
subprojects {
    dependencies {
    //to do: move these to the correct subprojects
        compile 'javax.inject:javax.inject:1'
        compile 'org.springframework:spring-context:4.1.4.RELEASE'
        compile 'org.springframework:spring-core:4.1.4.RELEASE'
        compile 'org.springframework:spring-beans:4.1.4.RELEASE'
        compile 'commons-logging:commons-logging:1.2'
        testCompile 'org.springframework:spring-test:4.1.4.RELEASE'
        testCompile 'org.testng:testng:6.1.1'
    }

    test {
        // enable TestNG support (default is JUnit)
        useTestNG() 
    }
}

// Resolve the dependencies between the layers in the individual project's build.gradle files
// add ONLY specific per project behaviour of the GLOBAL build here:

project(':contentplatform-web') {
}

project(':contentplatform-service') {
}

project(':contentplatform-dao') {
}

// Return a list of all the external libraries
def getLibraries() {
    return configurations.runtime.filter{!it.name.startsWith('contentplatform')}
}

// Copy all the libraries to a libs folder
task copyLibraries(type: Copy) {
    group 'Content Platform'
    description 'Copy all the external libraries to the /libs folder.'

    destinationDir file('./build/')

    into('libs/') {
        from getLibraries()
    }
}

// Perform the build task before building the big jar
jar {
    group 'Content Platform'
    description 'Package all the layers and dependencies into a big jar.'

    // The libraries are required to build
    dependsOn(copyLibraries)

    // The final big jar needs all the layers
    dependencies {
        compile project(':contentplatform-web'), project(':contentplatform-dao'),
            project(':contentplatform-service'), project(':contentplatform-model')
    }
    // Create a MANIFEST.MF file, the main class file is in the web layer
    manifest {
        attributes 'Implementation-Title': 'Content Platform',  
            'Implementation-Version': version,
            'Built-By': System.getProperty('user.name'),
            'Built-Date': new Date(),
            'Built-JDK': System.getProperty('java.version'),
            'Class-Path': getLibraries().collect{'../libs/' + it.getName()}.join(' '),
            'Main-Class': mainClassName
    }

    // Include the layers in the fat jar
    from(configurations.compile.filter{it.name.startsWith('contentplatform')}.collect{it.isDirectory() ? it : zipTree(it) }) {
        exclude "META-INF/*.SF"
        exclude "META-INF/*.DSA"
        exclude "META-INF/*.RSA"
    }

    // Save the fat jar in the root of the folder instead of in build/libs
    destinationDir file('.')
