twisted.internet.test.test_process.PTYProcessTestsBuilder(ProcessTestsBuilderBase) class documentation

Inherited from ProcessTestsBuilderBase:

Method	test_processTransportInterface	IReactorProcess.spawnProcess connects the protocol passed to it to a transport which provides IProcessTransport.
Method	test_write	IProcessTransport.write writes the specified bytes to the standard input of the child process.
Method	test_writeSequence	IProcessTransport.writeSequence writes the specified list of bytes to the standard input of the child process.
Method	test_writeToChild	IProcessTransport.writeToChild writes the specified bytes to the specified file descriptor of the child process.
Method	test_writeToChildBadFileDescriptor	IProcessTransport.writeToChild raises KeyError if passed a file descriptor which is was not set up by IReactorProcess.spawnProcess.
Method	test_spawnProcessEarlyIsReaped	If, before the reactor is started with IReactorCore.run, a process is started with IReactorProcess.spawnProcess and terminates, the process is reaped once the reactor is started.
Method	test_processExitedWithSignal	The reason argument passed to IProcessProtocol.processExited is a ProcessTerminated instance if the child process exits with a signal.
Method	test_systemCallUninterruptedByChildExit	If a child process exits while a system call is in progress, the system call should not be interfered with. In particular, it should not fail with EINTR.
Method	test_openFileDescriptors	Processes spawned with spawnProcess() close all extraneous file descriptors in the parent. They do have a stdin, stdout, and stderr open.
Method	test_errorDuringExec	When os.execvpe raises an exception, it will format that exception on stderr as UTF-8, regardless of system encoding information.
Method	test_timelyProcessExited	If a spawned process exits, processExited will be called in a timely manner.
Method	test_changeUID	If a value is passed for IReactorProcess.spawnProcess's uid, the child process is run with that UID.
Method	test_changeGID	If a value is passed for IReactorProcess.spawnProcess's gid, the child process is run with that GID.
Method	test_processExitedRaises	If IProcessProtocol.processExited raises an exception, it is logged.
Method	_writeTest	No summary
Method	_changeIDTest	No summary

Inherited from ReactorBuilder (via ProcessTestsBuilderBase):

Class Variable	skippedReactors	A dict mapping FQPN strings of reactors for which the tests defined by this class will be skipped to strings giving the skip message.
Class Variable	requiredInterfaces	A list of interfaces which the reactor must provide or these tests will be skipped. The default, None, means that no interfaces are required.
Instance Variable	reactorFactory	A no-argument callable which returns the reactor to use for testing.
Instance Variable	originalHandler	The SIGCHLD handler which was installed when setUp ran and which will be re-installed when tearDown runs.
Method	setUp	Clear the SIGCHLD handler, if there is one, to ensure an environment like the one which exists prior to a call to reactor.run.
Method	tearDown	Restore the original SIGCHLD handler and reap processes as long as there seem to be any remaining.
Method	unbuildReactor	Clean up any resources which may have been allocated for the given reactor by its creation or by a test which used it.
Method	buildReactor	Create and return a reactor using self.reactorFactory.
Method	getTimeout	Determine how long to run the test before considering it failed.
Method	runReactor	Run the reactor for at most the given amount of time.
Class Method	makeTestCaseClasses	Create a SynchronousTestCase subclass which mixes in cls for each known reactor and return a dict mapping their names to them.
Instance Variable	_reactors	A list of FQPN strings giving the reactors for which SynchronousTestCases will be created.
