public final class TestProvidingInputStream
extends DefaultCommandReader

An InputStream that, when read, provides test class names out of a queue.
The Stream provides only one test at a time, but only after provideNewTest() has been invoked.
The instance is used only in reusable forks in ForkStarter by one Thread.
