TestScope

Creates a TestScope.

It ensures that all the test module machinery is properly initialized.

• If context doesn't provide a TestCoroutineScheduler for orchestrating the virtual time used for delay-skipping, a new one is created, unless either

• a TestDispatcher is provided, in which case TestDispatcher.scheduler is used;

• at the moment of the creation of the scope, Dispatchers.Main is delegated to a TestDispatcher, in which case its TestCoroutineScheduler is used.

• If context doesn't have a TestDispatcher, a StandardTestDispatcher is created.

• A CoroutineExceptionHandler is created that makes runTest throw after the test is finished if there were any uncaught exceptions, or forwards the exceptions further in a platform-specific manner if by the time an exception happened, the test has completed. Passing a CoroutineExceptionHandler in context is unsupported.

• If context provides a Job, that job is used as a parent for the new scope.
