stk::test::pipe Namespace Reference

Namespace of Pipe test. More...

Classes
class	BasicWriteReadTask
	Tests basic Write()/Read() functionality in producer-consumer arrangement. More...
class	WriteBlocksWhenFullTask
	Tests that Write() blocks when the pipe is full and unblocks when space is freed. More...
class	ReadBlocksWhenEmptyTask
	Tests that Read() blocks when the pipe is empty and unblocks when data arrives. More...
class	TimeoutTask
	Tests that Write() and Read() return false within the expected time on timeout. More...
class	BulkWriteReadTask
	Tests WriteBulk()/ReadBulk() for multi-element block transfers. More...
class	GetSizeIsEmptyTask
	Tests GetSize() and IsEmpty() reflect accurate pipe state. More...
class	MultiProducerConsumerTask
	Tests concurrent multi-producer / multi-consumer throughput. More...
class	StressTestTask
	Stress test of Pipe under full five-task contention. More...
