@NullMarked @CacheableTask public abstract 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.

     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

  - ### getDebug

    public boolean getDebug()
    Determines whether debugging is enabled for the test process. When enabled — `debug = true` — the process is started in a suspended state, listening on port 5005. You should disable parallel test execution when debugging and you will need to reattach the debugger occasionally if you use a non-zero value for `getForkEvery()`.

    Since Gradle 5.6, you can configure the port and other Java debug properties via `JavaForkOptions.debugOptions(Action)`.

    Specified by:
      `getDebug` in interface `JavaForkOptions`
    Returns:
      true when debugging is enabled, false to disable.

  - ### setDebug

    public void setDebug(boolean enabled)

    @Internal public long getForkEvery()
    Returns the maximum number of test classes to execute in a forked test process. The forked test process will be restarted when this limit is reached.

    By default, Gradle automatically uses a separate JVM when executing tests.

    - A value of `0` (no limit) means to reuse the test process for all test classes. This is the default.
    - A value of `1` means that a new test process is started for every test class. This is very expensive.
    - A value of `N` means that a new test process is started after `N` test classes.
    This property can have a large impact on performance due to the cost of stopping and starting each test process. It is unusual for this property to be changed from the default.

      The maximum number of test classes to execute in a test process. Returns 0 when there is no maximum.

  - ### setForkEvery

    public void setForkEvery(long forkEvery)

    Since:
      8.1

  - ### getMaxParallelForks

    @Internal public int getMaxParallelForks()
    Returns the maximum number of test processes to start in parallel.

    By default, Gradle executes a single test class at a time.

    - A value of `1` means to only execute a single test class in a single test process at a time. This is the default.
    - A value of `N` means that up to `N` test processes will be started to execute test classes. This can improve test execution time by running multiple test classes in parallel.
    This property cannot exceed the value of max-workers for the current build. Gradle will also limit the number of started test processes across all `Test` tasks.
    Returns:
      The maximum number of forked test processes.

  - ### setMaxParallelForks

    public void setMaxParallelForks(int maxParallelForks)
    Sets the maximum number of test processes to start in parallel.

    By default, Gradle executes a single test class at a time but allows multiple `Test` tasks to run in parallel.

    Parameters:
      `maxParallelForks` - The maximum number of forked test processes. Use 1 to disable parallel test execution for this task.

  - ### getCandidateClassFiles
