Java – gradle compiles but does not run TestNG tests

We just started using gradle and TestNG in our project, so I'm checking if there are actually no test failures I was surprised to see that it didn't The test was selected and compiled correctly, so I saw the class file I also got a report on running, but it said 0 tests (expected 2) Running gradle clean test - I gives the following:

:contentplatform-service:compileTestJava (Thread[Daemon worker Thread 7,5,main])

SuperSimpleTest. java：

package nl.xillio.contentplatform.service;

import org.testng.Assert;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

@Test
public class SuperSimpleTest {

    @BeforeClass
    public void setUp() {
        // code that will be invoked when this test is instantiated
    }

    @Test
    public void testtest() {
        Assert.assertEquals(true,true);
    }
}

build. Gradle contains:

test {
    // enable TestNG support (default is JUnit)
    useTestNG()
    scanForTestClasses = false  
    include '**/*'

    testLogging {
        showStandardStreams = true

        // log results to "build/test-results" directory
        exceptionFormat "full"
        events "started","passed","skipped","Failed","standardOut","standardError"
    }
}

I've seen other questions on this topic, where I found a hint to use scanfortestclasses = false as a solution (see https://issues.gradle.org/browse/GRADLE-1682 ）However, the issue seems irrelevant Did I make any other rookie mistakes here? How can I make supersimpletest execute?

Update: I tried to force gradle to run a specific test, and the result was an interesting error: gradle complaints about JUnit version TestNG task

Solution

This is indeed a foolish noob mistake We are using a multi - project setup that contains a main project and several folders at the same level, including code and tests I accidentally used build Gradle only configures the main project to use TestNG The solution is to include the test objectives in all projects or subproject closures What is the difference between allprojects and subprojects

So this is the job 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('.')
}
