twisted.pair.test.test_tuntap.TunTests(TunnelTestsMixin, SynchronousTestCase) class documentation

Inherited from TunnelTestsMixin:

Method	setUp	Create an in-memory I/O system and set up a TuntapPort against it.
Method	test_startListeningOpensDevice	TuntapPort.startListening opens the tunnel factory character special device "/dev/net/tun" and configures it as a tun tunnel.
Method	test_startListeningSetsConnected	TuntapPort.startListening sets connected on the port object to True.
Method	test_startListeningConnectsProtocol	TuntapPort.startListening calls makeConnection on the protocol the port was initialized with, passing the port as an argument.
Method	test_startListeningStartsReading	TuntapPort.startListening passes the port instance to the reactor's addReader method to begin watching the port's file descriptor for data to read.
Method	test_startListeningHandlesOpenFailure	TuntapPort.startListening raises CannotListenError if opening the tunnel factory character special device fails.
Method	test_startListeningHandlesConfigureFailure	TuntapPort.startListening raises CannotListenError if the ioctl call to configure the tunnel device fails.
Method	test_stopListeningStopsReading	TuntapPort.stopListening returns a Deferred which fires after the port has been removed from the reactor's reader list by passing it to the reactor's removeReader method.
Method	test_stopListeningUnsetsConnected	After the Deferred returned by TuntapPort.stopListening fires, the connected attribute of the port object is set to False.
Method	test_stopListeningStopsProtocol	TuntapPort.stopListening calls doStop on the protocol the port was initialized with.
Method	test_stopListeningWhenStopped	TuntapPort.stopListening returns a Deferred which succeeds immediately if it is called when the port is not listening.
Method	test_multipleStopListening	It is safe and a no-op to call TuntapPort.stopListening more than once with no intervening TuntapPort.startListening call.
Method	test_loseConnection	TuntapPort.loseConnection stops the port and is deprecated.
Method	test_eagainStopsReading	Once TuntapPort.doRead encounters an EAGAIN errno from a read call, it returns.
Method	test_ewouldblockStopsReading	Once TuntapPort.doRead encounters an EWOULDBLOCK errno from a read call, it returns.
Method	test_eintrblockStopsReading	Once TuntapPort.doRead encounters an EINTR errno from a read call, it returns.
Method	test_unhandledReadError	If Tuntap.doRead encounters any exception other than one explicitly handled by the code, the exception propagates to the caller.
Method	test_unhandledEnvironmentReadError	Just like test_unhandledReadError, but for the case where the exception that is not explicitly handled happens to be of type EnvironmentError (OSError or IOError).
Method	test_doReadSmallDatagram	TuntapPort.doRead reads a datagram of fewer than TuntapPort.maxPacketSize from the port's file descriptor and passes it to its protocol's datagramReceived method.
Method	test_doReadLargeDatagram	TuntapPort.doRead reads the first part of a datagram of more than TuntapPort.maxPacketSize from the port's file descriptor and passes the truncated data to its protocol's datagramReceived method.
Method	test_doReadSeveralDatagrams	TuntapPort.doRead reads several datagrams, of up to TuntapPort.maxThroughput bytes total, before returning.
Method	test_datagramReceivedException	If the protocol's datagramReceived method raises an exception, the exception is logged.
Method	test_datagramReceivedExceptionIdentifiesProtocol	The exception raised by datagramReceived is logged with a message identifying the offending protocol.
Method	test_write	TuntapPort.write sends a datagram into the tunnel.
Method	test_interruptedWrite	If the platform write call is interrupted (causing the Python wrapper to raise IOError with errno set to EINTR), the write is re-tried.
Method	test_unhandledWriteError	Any exception raised by the underlying write call, except for EINTR, is propagated to the caller.
Method	test_writeSequence	TuntapPort.writeSequence sends a datagram into the tunnel by concatenating the byte strings in the list passed to it.
Method	test_getHost	TuntapPort.getHost returns a TunnelAddress including the tunnel's type and name.
Method	test_listeningString	The string representation of a TuntapPort instance includes the tunnel type and interface and the protocol associated with the port.
Method	test_unlisteningString	The string representation of a TuntapPort instance includes the tunnel type and interface and the protocol associated with the port.
Method	test_logPrefix	TuntapPort.logPrefix returns a string identifying the application protocol and the type of tunnel.
Method	_tunnelTypeOnly	Mask off any flags except for TunnelType.IFF_TUN and TunnelType.IFF_TAP.
Method	_stopPort	Verify that the stopListening method of an IListeningPort removes that port from the reactor's "readers" set and also that the Deferred returned by that method fires with None.
Method	_stopsReadingTest	Test that TuntapPort.doRead has no side-effects under a certain exception condition.
Method	_datagramReceivedException	Deliver some data to a TuntapPort hooked up to an application protocol that raises an exception from its datagramReceived method.

Inherited from SynchronousTestCase:

Instance Variable	failureException	An exception class, defaulting to FailTest. If the test method raises this exception, it will be reported as a failure, rather than an exception. All of the assertion methods raise this if the assertion fails.
Instance Variable	skip	None or a string explaining why this test is to be skipped. If defined, the test will not be run. Instead, it will be reported to the result object as 'skipped' (if the TestResult supports skipping).
Instance Variable	todo	None, a string or a tuple of (errors, reason) where errors is either an exception class or an iterable of exception classes, and reason is a string. See Todo or makeTodo for more information.
Instance Variable	suppress	None or a list of tuples of (args, kwargs) to be passed to warnings.filterwarnings. Use these to suppress warnings raised in a test. Useful for testing deprecated code. See also util.suppress.
Method	__init__	Undocumented
Method	__eq__	No summary
Method	__ne__	Undocumented
Method	__hash__	Undocumented
Method	shortDescription	Undocumented
Method	getSkip	No summary
Method	getTodo	No summary
Method	runTest	If no methodName argument is passed to the constructor, run will treat this method as the thing with the actual test inside.
Method	run	Run the test case, storing the results in result.
Method	addCleanup	Add the given function to a list of functions to be called after the test has run, but before tearDown.
Method	patch	Monkey patch an object for the duration of the test.
Method	flushLoggedErrors	Remove stored errors received from the log.
Method	flushWarnings	Remove stored warnings from the list of captured warnings and return them.
Method	callDeprecated	Call a function that should have been deprecated at a specific version and in favor of a specific alternative, and assert that it was thusly deprecated.
Method	mktemp	Create a new path name which can be used for a new file or directory.
Method	_getSuppress	No summary
Method	_getSkipReason	Return the reason to use for skipping a test method.
Method	_run	Run a single method, either a test method or fixture.
Method	_runFixturesAndTest	Run setUp, a test method, test cleanups, and tearDown.
Method	_runCleanups	Synchronously run any cleanups which have been added.
Method	_installObserver	Undocumented
Method	_removeObserver	Undocumented

Inherited from _Assertions (via SynchronousTestCase):

Method	fail	Absolutely fail the test. Do not pass go, do not collect $200.
Method	assertFalse	Fail the test if condition evaluates to True.
Method	assertTrue	Fail the test if condition evaluates to False.
Method	assertRaises	Fail the test unless calling the function f with the given args and kwargs raises exception. The failure will report the traceback and call stack of the unexpected exception.
Method	assertEqual	Fail the test if first and second are not equal.
Method	assertIs	Fail the test if first is not second. This is an obect-identity-equality test, not an object equality (i.e. __eq__) test.
Method	assertIsNot	Fail the test if first is second. This is an obect-identity-equality test, not an object equality (i.e. __eq__) test.
Method	assertNotEqual	Fail the test if first == second.
Method	assertIn	Fail the test if containee is not found in container.
Method	assertNotIn	Fail the test if containee is found in container.
Method	assertNotAlmostEqual	Fail if the two objects are equal as determined by their difference rounded to the given number of decimal places (default 7) and comparing to zero.
Method	assertAlmostEqual	Fail if the two objects are unequal as determined by their difference rounded to the given number of decimal places (default 7) and comparing to zero.
Method	assertApproximates	Fail if first - second > tolerance
Method	assertSubstring	Fail if substring does not exist within astring.
Method	assertNotSubstring	Fail if astring contains substring.
Method	assertWarns	Fail if the given function doesn't generate the specified warning when called. It calls the function, checks the warning, and forwards the result of the function if everything is fine.
Method	assertIsInstance	Fail if instance is not an instance of the given class or of one of the given classes.
Method	assertNotIsInstance	Fail if instance is an instance of the given class or of one of the given classes.
Method	successResultOf	Return the current success result of deferred or raise self.failureException.
Method	failureResultOf	Return the current failure result of deferred or raise self.failureException.
