twisted.internet.test.test_process.ProcessTestsBuilder

Builder defining tests relating to IReactorProcess for child processes which do not have a PTY.

Method	test_childConnectionLost	`IProcessProtocol.childConnectionLost` is called each time a file descriptor associated with a child process is closed.
Method	test_processEnded	`IProcessProtocol.processEnded` is called after the child process exits and `IProcessProtocol.childConnectionLost` is called for each of its file descriptors.
Method	test_processExited	`IProcessProtocol.processExited` is called when the child process exits, even if file descriptors associated with the child are still open.
Method	makeSourceFile	Write the given list of lines to a text file and return the absolute path to it.
Method	test_shebang	Spawning a process with an executable which is a script starting with an interpreter definition line (#!) uses that interpreter to evaluate the script.
Method	test_processCommandLineArguments	Arguments given to spawnProcess are passed to the child process as originally intended.

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 `SynchronousTestCase`s will be created.

def test_childConnectionLost(self):

IProcessProtocol.childConnectionLost is called each time a file descriptor associated with a child process is closed.

def test_processEnded(self):

IProcessProtocol.processEnded is called after the child process exits and IProcessProtocol.childConnectionLost is called for each of its file descriptors.

def test_processExited(self):

IProcessProtocol.processExited is called when the child process exits, even if file descriptors associated with the child are still open.

def makeSourceFile(self, sourceLines):

Write the given list of lines to a text file and return the absolute path to it.

def test_shebang(self):

Spawning a process with an executable which is a script starting with an interpreter definition line (#!) uses that interpreter to evaluate the script.

def test_processCommandLineArguments(self):

Arguments given to spawnProcess are passed to the child process as originally intended.
