Returns the arguments that were used to create this Runner.

Scala.js specific: Deserialize a task that has been serialized by serializeTask of another or this Runner.

The resulting task must associate with this runner.

Indicates the client is done with this Runner instance.

After invoking the done method on a Runner instance, the client should no longer invoke the task methods on that instance. (If the client does invoke task after done, it will be rewarded with an IllegalStateException.)

Similarly, after returning from done, the test framework should no longer write any messages to the Logger, nor fire any more events to the EventHandler, passed to Framework.runner. If the test framework has not completed writing log messages or firing events when the client invokes done, the framework should not return from done until it is finished sending messages and events, and may block the thread that invoked done until it is actually done.

In short, by invoking done, the client indicates it is done invoking the task methods for this run. By returning from done, the test framework indicates it is done writing log messages and firing events for this run.

If the client invokes done more than once on the same Runner instance, the test framework should on subsequent invocations should throw IllegalStateException.

The test framework may send a summary (i.e., a message giving total tests succeeded, failed, and so on) to the user via a log message. If so, it should return the summary from done. If not, it should return an empty string. The client may use the return value of done to decide whether to display its own summary message.

The test framework may return a multi-lines string (i.e., a message giving total tests succeeded, failed and so on) to the client.

In Scala.js, the client must not call this method before all execute methods of all Tasks have called their completion continuation. Otherwise, the Framework should throw an IllegalStateException (since it cannot block).

Further, if this is the controller, the client must not call this method before all done methods of all workers have returned (otherwise, an IllegalStateException is thrown). If this is a worker, the returned string is ignored.

Scala.js specific: Invoked on the controller Runner when a worker sends a message (through the channel provided by the client).

The controller may send a message back to the sending worker by returning the message in a Some.

Invoked on a worker Runner when the controller responds to a message (sent by the worker via the supplied closure in slaveRunner, aka workerRunner; see the Scaladoc of sbt.testing.Framework about the name.). The return value of the call is ignored in this case.

Remote args that will be passed to Runner in a sub-process as remoteArgs.

Scala.js specific: Serialize a task created by tasks or returned from execute.

The resulting string will be passed to the deserializeTask method of another runner. After calling this method, the passed task is invalid and should dissociate from this runner.

Returns an array of tasks that when executed will run tests and suites determined by the passed TaskDefs.

Each returned task, when executed, will run tests and suites determined by the test class name, fingerprints, "explicitly specified" field, and selectors of one of the passed TaskDefs.

This tasks method may be called with TaskDefs containing the same value for testClassName but different fingerprints. For example, if both a class and its companion object were test classes, the tasks method could be passed an array containing TaskDefs with the same name but with a different value for fingerprint.isModule.

A test framework may "reject" a requested task by returning no Task for that TaskDef.
