twisted.test.test

Variable	CONCURRENT_PROCESS_TEST_COUNT	The number of concurrent processes to use to stress-test the spawnProcess API. This value is tuned to a number of processes which has been determined to stay below various experimentally-determined limitations of our supported platforms. Particularly, Windows XP seems to have some undocumented limitations which cause spurious failures if this value is pushed too high. Please see this ticket for a discussion of how we arrived at its current value.
Variable	properEnv	A copy of `os.environ` which has `bytes` keys/values on POSIX platforms and native `str` keys/values on Windows.
Class	StubProcessProtocol	ProcessProtocol counter-implementation: all methods on this class raise an exception, so instances of this may be used to verify that only certain methods are called.
Class	ProcessProtocolTests	Tests for behavior provided by the process protocol base class, `protocol.ProcessProtocol`.
Class	TrivialProcessProtocol	Simple process protocol for tests purpose.
Class	TestProcessProtocol	No class docstring; 2/4 methods documented
Class	EchoProtocol	Undocumented
Class	SignalProtocol	A process protocol that sends a signal when data is first received.
Class	TestManyProcessProtocol	Undocumented
Class	UtilityProcessProtocol	Helper class for launching a Python process and getting a result from it.
Class	GetArgumentVector	Protocol which will read a serialized argv from a process and expose it to interested parties.
Class	GetEnvironmentDictionary	Protocol which will read a serialized environment dict from a process and expose it to interested parties.
Class	ProcessTests	Test running a process.
Class	TwoProcessProtocol	Undocumented
Class	TestTwoProcessesBase	Undocumented
Class	TwoProcessesNonPosixTests	Undocumented
Class	TwoProcessesPosixTests	Undocumented
Class	FDChecker	Undocumented
Class	FDTests	Undocumented
Class	Accumulator	Accumulate data from a process.
Class	PosixProcessBase	Test running processes.
Class	MockSignal	Neuter `signal.signal`, but pass other attributes unscathed
Class	MockOS	The mock OS: overwrite `os`, `fcntl` and {sys} functions with fake ones.
Class	DumbProcessWriter	A fake `process.ProcessWriter` used for tests.
Class	DumbProcessReader	A fake `process.ProcessReader` used for tests.
Class	DumbPTYProcess	A fake `process.PTYProcess` used for tests.
Class	MockProcessTests	Mock a process runner to test forked child code path.
Class	PosixProcessTests	No class docstring; 1/2 methods documented
Class	PosixProcessPTYTests	Just like PosixProcessTests, but use ptys instead of pipes.
Class	Win32SignalProtocol	A win32-specific process protocol that handles `processEnded` differently: processes should exit with exit code 1.
Class	Win32ProcessTests	Test process programs that are packaged with twisted.
Class	Win32UnicodeEnvironmentTests	Tests for Unicode environment on Windows
Class	DumbWin32ProcTests	`twisted.internet._dumbwin32proc` tests.
Class	Win32CreateProcessFlagsTests	Check the flags passed to CreateProcess.
Class	UtilTests	Tests for process-related helper functions (currently only `procutils.which`.
Class	ClosingPipesProcessProtocol	Undocumented
Class	ClosingPipesTests	No class docstring; 4/4 methods documented
