twisted.internet.test.test_tcp.TCP4ClientTestsBuilder(TCPClientTestsBase) class documentation

Inherited from TCPClientTestsBase:

Instance Variable	endpoints	A client/server endpoint creator appropriate to the address family being tested. (type: twisted.internet.test.connectionmixins.EndpointCreator)
Instance Variable	interface 0	An IP address literal to locally bind a socket to as well as to connect to. This can be any valid interface for the local host. (type: str)
Instance Variable	port 0	An unused local listening port to listen on and connect to. This will be used in conjunction with the interface. (Depending on what they're testing, some tests will locate their own port with findFreePort instead.) (type: int)
Instance Variable	family	an address family constant, such as socket.AF_INET, socket.AF_INET6, or socket.AF_UNIX, which indicates the address family of the transport type under test. (type: int)
Instance Variable	addressClass	the twisted.internet.interfaces.IAddress implementor associated with the transport type under test. Must also be a 3-argument callable which produces an instance of same. (type: type)
Instance Variable	fakeDomainName	A fake domain name to use, to simulate hostname resolution and to distinguish between hostnames and IP addresses where necessary. (type: str)
Method	port	Return the port number to connect to, using self._port set up by listen if available.
Method	interface	Return the interface attribute from the endpoints object.
Method	listen	Start a TCP server with the given factory.
Method	connect	Start a TCP client with the given factory.
Method	test_buildProtocolReturnsNone	When the factory's buildProtocol returns None the connection is gracefully closed.
Method	test_addresses	No summary
Method	test_badContext	If the context factory passed to ITCPTransport.startTLS raises an exception from its getContext method, that exception is raised by ITCPTransport.startTLS.

Inherited from ReactorBuilder (via TCPClientTestsBase):

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.

Inherited from ConnectionTestsMixin (via TCPClientTestsBase):

Method	test_logPrefix	Client and server transports implement ILoggingContext.logPrefix to return a message reflecting the protocol they are running.
Method	test_writeAfterDisconnect	After a connection is disconnected, ITransport.write and ITransport.writeSequence are no-ops.
Method	test_protocolGarbageAfterLostConnection	After the connection a protocol is being used for is closed, the reactor discards all of its references to the protocol.

Inherited from StreamClientTestsMixin (via TCPClientTestsBase):

Method	test_interface	The connect method returns an object providing IConnector.
Method	test_clientConnectionFailedStopsReactor	The reactor can be stopped by a client factory's clientConnectionFailed method.
Method	test_connectEvent	This test checks that we correctly get notifications event for a client. This ought to prevent a regression under Windows using the GTK2 reactor. See #3925.
Method	test_unregisterProducerAfterDisconnect	No summary
Method	test_disconnectWhileProducing	If loseConnection is called while a producer is registered with the transport, the connection is closed after the producer is unregistered.
