# Test

@NullMarked
@CacheableTask
abstract class Test : AbstractTestTask, JavaForkOptions, PatternFilterable(source)

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.

    plugins {
        id("java-library") // adds 'test' task
    }

    test {
      // discover and execute JUnit4-based tests
      useJUnit()

      // discover and execute TestNG-based tests
      useTestNG()

      // discover and execute JUnit Platform-based tests
      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

      // skip an actual test execution
      dryRun = 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
