      public class Test
      extends AbstractTestTask
      implements JavaForkOptions, PatternFilterable

  Executes JUnit (3.8.x, 4.x or 5.x) or TestNG tests. Test are always run in (one or more) separate JVMs. The sample below shows various configuration options.

       apply plugin: 'java' // adds 'test' task

       test {
         // enable TestNG support (default is JUnit)
         useTestNG()
         // enable JUnit Platform (a.k.a. JUnit 5) support
         useJUnitPlatform()

         // set a system property for the test JVM(s)
         systemProperty 'some.prop', 'value'

         // explicitly include or exclude tests
         include 'org/foo/**'
         exclude 'org/boo/**'

         // show standard out and standard error of the test JVM(s) on the console
         testLogging.showStandardStreams = true

         // set heap size for the test JVM(s)
         minHeapSize = "128m"
         maxHeapSize = "512m"

         // set JVM arguments for the test JVM(s)
         jvmArgs '-XX:MaxPermSize=256m'

         // listen to events in the test execution lifecycle
         beforeTest { descriptor ->
            logger.lifecycle("Running test: " + descriptor)
         }

         // Fail the 'test' task on the first test failure
         failFast = true

         // listen to standard out and standard error of the test JVM(s)
         onOutput { descriptor, event ->
            logger.lifecycle("Test: " + descriptor + " produced standard out/err: " + event.message )
         }
       }

  The test process can be started in debug mode (see `getDebug()`) in an ad-hoc manner by supplying the `--debug-jvm` switch when invoking the build.

       gradle someTestTask --debug-jvm
