Please help me, I want to automate testing my students’ turnins. Therefore I copy a build.gradle file into each turnin directory and run a build. Since I have a set of compiled JUnit tests in another project, I added the directory with the .class files to the testRuntime classpath. Unfortunately the test task ignores the classes and executes 0 tests. What’s my mistake? ```gradle //This build file will be used on each turnin apply plugin: 'java' apply plugin: 'eclipse' repositories { mavenCentral() } dependencies { testCompile 'junit:junit:4.10' testCompile 'org.hamcrest:hamcrest-all:1.1' testRuntime files('../../turnin-tests/build/classes/test') } sourceSets { main { java { srcDir '.' } } } test.doFirst { println "${project.sourceSets.test.runtimeClasspath.files.join('\n')}" } ``` ```gradle mak:00864359 klaus$ pwd /Users/klaus/Documents/dritte/hm/2011-se1/turnin-explode/00864359 mak:00864359 klaus$ ll total 48 drwxr-xr-x@ 7 klaus staff 238 30 Nov 08:39 . drwxr-xr-x 35 klaus staff 1190 30 Nov 08:20 .. -rw-r--r-- 1 klaus staff 4951 30 Nov 06:57 ICEControlCenter.java -rw-r--r-- 1 klaus staff 931 30 Nov 06:21 SlidingWindow.java -rw-r--r-- 1 klaus staff 1465 30 Nov 06:49 Wagon.java -rw-r--r-- 1 klaus staff 1721 30 Nov 06:21 Worm.java -rw-r--r-- 1 klaus staff 425 30 Nov 08:28 build.gradle mak:00864359 klaus$ ll ../../turnin-tests/build/classes/test total 56 drwxr-xr-x 8 klaus staff 272 30 Nov 08:10 . drwxr-xr-x 4 klaus staff 136 30 Nov 08:10 .. -rw-r--r-- 1 klaus staff 5891 30 Nov 08:10 ICEControllerCenterTestBasic.class -rw-r--r-- 1 klaus staff 2194 30 Nov 08:10 ICEControllerCenterTestFreeTracks.class -rw-r--r-- 1 klaus staff 1785 30 Nov 08:10 ICEControllerCenterTestShorten.class -rw-r--r-- 1 klaus staff 2916 30 Nov 08:10 SlidingWindowTest.class -rw-r--r-- 1 klaus staff 2105 30 Nov 08:10 WagonTest.class -rw-r--r-- 1 klaus staff 3861 30 Nov 08:10 WormTest.class mak:00864359 klaus$ gradle test :compileJava :processResources UP-TO-DATE :classes :compileTestJava UP-TO-DATE :processTestResources UP-TO-DATE :testClasses UP-TO-DATE :test /Users/klaus/Documents/dritte/hm/2011-se1/turnin-explode/00864359/build/classes/test /Users/klaus/Documents/dritte/hm/2011-se1/turnin-explode/00864359/build/resources/test /Users/klaus/Documents/dritte/hm/2011-se1/turnin-explode/00864359/build/classes/main /Users/klaus/Documents/dritte/hm/2011-se1/turnin-explode/00864359/build/resources/main /Users/klaus/Documents/dritte/hm/2011-se1/turnin-tests/build/classes/test /Users/klaus/.gradle/caches/artifacts-4/junit/junit/c12498cf18507aa6433a94eb7d3e77d5/jars/junit-4.10.jar /Users/klaus/.gradle/caches/artifacts-4/org.hamcrest/hamcrest-all/c12498cf18507aa6433a94eb7d3e77d5/jars/hamcrest-all-1.1.jar /Users/klaus/.gradle/caches/artifacts-4/org.hamcrest/hamcrest-core/c12498cf18507aa6433a94eb7d3e77d5/jars/hamcrest-core-1.1.jar ``` The directory build/test-results is empty, and the test report html file says 0 tests were executed. :-? ---

To add the contents of a directory to a configuration, you need to use ‘fileTree()’, not ‘files()’. The latter just gives a ‘flat’ collection of one or more File’s. ---

Hi Peter, a Thanks for your answer. Unfortunately replacing ‘files()’ with ‘fileTree()’ doesn’t solve my issue. Actually ‘project.sourceSets.test.runtimeClasspath’ looked better before, since it contained the directory. Any further ideas? Regards, Klaus ---

Have you checked that the file tree that you construct contains the expected classes? ---

I found it! The test task’s property ‘testClassesDir’ was the solution: ```gradle //This build file will be used on each turnin apply plugin: 'java' apply plugin: 'eclipse' repositories { mavenCentral() } dependencies { testCompile 'junit:junit:4.10' testCompile 'org.hamcrest:hamcrest-all:1.1' } sourceSets { main { java { srcDir '.' } } } test { testClassesDir file('../../turnin-tests/build/classes/test') } ``` ---

Yes, you are right. Adding the directory itself was the right thing to do. From what I can see in the source code, Gradle only looks for test classes in build/classes/test (more precisely test.testClassesDir). So your best chance may be to copy your test classes there with a Copy task. Or you turn things around, always execute the build which contains the tests but pull in the code to be tested from different places. ---

If the project itself doesn’t contain any tests, that’s a good solution.
