All Implemented Interfaces:

Closeable, AutoCloseable, NotifiableTestStream

public final class TestProvidingInputStream
extends AbstractCommandStream

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.
After providing each test class name, followed by a newline character, a flush is performed on the FlushReceiver provided by the FlushReceiverProvider that can be set using AbstractForkInputStream.setFlushReceiverProvider(FlushReceiverProvider).
The instance is used only in reusable forks in ForkStarter by one Thread.

public TestProvidingInputStream(Queue<String> testClassNames)

C'tor

Parameters:

testClassNames - source of the tests to be read from this stream

Method Detail

skipSinceNextTest

public void skipSinceNextTest()

Description copied from interface: NotifiableTestStream

Sends an event to a fork jvm in order to skip tests. Returns immediately without blocking.

shutdown

public void shutdown(Shutdown shutdownType)

noop

nextCommand

protected Command nextCommand()

Specified by:

nextCommand in class AbstractCommandStream

beforeNextCommand

protected void beforeNextCommand()
                          throws IOException

Description copied from class: AbstractCommandStream
