twisted.internet.test.test_endpoints._HostnameEndpointMemoryReactorMixin

Known subclasses: twisted.internet.test.test_endpoints.HostnameEndpointMemoryIPv4ReactorTests, twisted.internet.test.test_endpoints.HostnameEndpointMemoryIPv6ReactorTests

Common methods for testing HostnameEndpoint against MemoryReactor instances that do not provide IReactorPluggableNameResolver.

Method	synchronousDeferredToThread	A synchronous version of `deferToThread`.
Method	expectedClients	Extract expected clients from the reactor.
Method	connectArgs
Method	assertConnectArgs	No summary
Method	test_endpointConnectFailure	When `HostnameEndpoint.connect` cannot connect to its destination, the returned `Deferred` will fail with `ConnectError`.
Method	test_deprecation	Instantiating `HostnameEndpoint` with a reactor that does not provide `IReactorPluggableResolver` emits a deprecation warning.
Method	test_errorsLogged	Hostname resolution errors are logged.

Inherited from ClientEndpointTestCaseMixin:

Method	test_interface	The endpoint provides `interfaces.IStreamClientEndpoint`
Method	retrieveConnectedFactory	Retrieve a single factory that has connected using the given reactor. (This behavior is valid for TCP and SSL but needs to be overridden for UNIX.)
Method	test_endpointConnectSuccess	A client endpoint can connect and returns a deferred who gets called back with a protocol instance.
Method	test_endpointConnectingCancelled	Calling `Deferred.cancel` on the `Deferred` returned from `IStreamClientEndpoint.connect` is errbacked with an expected `ConnectingCancelledError` exception.
Method	test_endpointConnectNonDefaultArgs	The endpoint should pass it's connectArgs parameter to the reactor's listen methods.

def synchronousDeferredToThread(self, f, *args, **kwargs):

A synchronous version of deferToThread.

Parameters	f	The callable to invoke. (type: `callable`)
	args	Positional arguments to the callable.
	kwargs	Keyword arguments to the callable.
Returns	A `Deferred` that fires with the result of applying `f` to `args` and `kwargs` or the exception raised.

def expectedClients(self, reactor):

Extract expected clients from the reactor.

Parameters	reactor	The `MemoryReactor` under test.
Returns	List of calls to `IReactorTCP.connectTCP`

def connectArgs(self):

Returns dict of keyword arguments to pass to connect.

def assertConnectArgs(self, receivedArgs, expectedArgs):

Compare host, port, timeout, and bindAddress in receivedArgs to expectedArgs. We ignore the factory because we don't only care what protocol comes out of the IStreamClientEndpoint.connect call.

Parameters	receivedArgs	`tuple` of (`host`, `port`, `factory`, `timeout`, `bindAddress`) that was passed to `IReactorTCP.connectTCP`.
	expectedArgs	`tuple` of (`host`, `port`, `factory`, `timeout`, `bindAddress`) that we expect to have been passed to `IReactorTCP.connectTCP`.

def test_endpointConnectFailure(self):

overrides twisted.internet.test.test_endpoints.ClientEndpointTestCaseMixin.test_endpointConnectFailure

When HostnameEndpoint.connect cannot connect to its destination, the returned Deferred will fail with ConnectError.

def test_deprecation(self):

Instantiating HostnameEndpoint with a reactor that does not provide IReactorPluggableResolver emits a deprecation warning.

def test_errorsLogged(self):

Hostname resolution errors are logged.
