Gradle compiles but does not run TestNG tests

Question

We have just started using Gradle and TestNG in our project, so I am checking if refusing any test does not allow the build. I was very surprised to see that this is not so. Tests are compiled and compiled correctly, so I see class files. I also get a launch report, but it says 0 tests (2 expected). Running gradle clean test -i gives me the following:

 :contentplatform-service:compileTestJava (Thread[Daemon worker Thread 7,5,main]) started. :contentplatform-service:compileTestJava Executing task ':contentplatform-service:compileTestJava' (up-to-date check took 0.08 secs) due to: Output file D:\Dev\contentplatform-service\build\classes\test has changed.

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 already looked at other questions on this topic, and there I found a hint to use scanForTestClasses = false as a workaround (see https://issues.gradle.org/browse/GRADLE-1682 ). However, this problem seems unrelated. Can I make some other mistake? How can I make SuperSimpleTest just execute?

UPDATE: I tried to get Gradle to run a specific test with an interesting error as a result: Gradle complains about the JUnit version of the TestNG task

It was a stupid noob mistake. We use multi-project setup with the main project and several folders at the same level, which contain code and tests. build.gradle I used a randomly configured master project to use TestNG. The solution is to include a control target in the closure of allprojects or subprojects . This is explained here: What is the difference between all projects and subprojects

So here is a 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 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('.') }
