Tests for the implementation of ISSLTransport which runs over another ITransport.

Method handshakeProtocols Start handshake between TLS client and server.
Method hugeWrite If a very long string is passed to TLSMemoryBIOProtocol.write, any trailing part of it which cannot be send immediately is buffered and sent later.
Method test_connectionLostOnlyAfterUnderlyingCloses The user protocol's connectionLost is only called when transport underlying TLS is disconnected.
Method test_disorderlyShutdown If a TLSMemoryBIOProtocol loses its connection unexpectedly, this is reported to the application.
Method test_errorWriting Errors while writing cause the protocols to be disconnected.
Method test_getHandle TLSMemoryBIOProtocol.getHandle returns the OpenSSL.SSL.Connection instance it uses to actually implement TLS.
Method test_getPeerCertificate TLSMemoryBIOProtocol.getPeerCertificate returns the OpenSSL.crypto.X509 instance representing the peer's certificate.
Method test_handshake The TLS handshake is performed when TLSMemoryBIOProtocol is connected to a transport.
Method test_handshakeFailure TLSMemoryBIOProtocol reports errors in the handshake process to the application-level protocol object using its connectionLost method and disconnects the underlying transport.
Method test_hugeWrite Undocumented
Method test_hugeWrite_TLSv1_2 Undocumented
Method test_interfaces TLSMemoryBIOProtocol instances provide ISSLTransport and ISystemHandle.
Method test_loseConnectionAfterConnectionLost If TLSMemoryBIOProtocol.loseConnection is called after connectionLost, it does nothing.
Method test_loseConnectionAfterHandshake TLSMemoryBIOProtocol.loseConnection sends a TLS close alert and shuts down the underlying connection cleanly on both sides, after transmitting all buffered data.
Method test_loseConnectionTwice If TLSMemoryBIOProtocol.loseConnection is called multiple times, all but the first call have no effect.
Method test_makeConnection When TLSMemoryBIOProtocol is connected to a transport, it connects the protocol it wraps to a transport.
Method test_multipleWrites If multiple separate TLS messages are received in a single chunk from the underlying transport, all of the application bytes from each message are delivered to the application-level protocol.
Method test_noCircularReferences TLSMemoryBIOProtocol doesn't leave circular references that keep it in memory after connection is closed.
Method test_unexpectedEOF Unexpected disconnects get converted to ConnectionLost errors.
Method test_wrappedProtocolInterfaces TLSMemoryBIOProtocol instances provide the interfaces provided by the transport they wrap.
Method test_writeAfterHandshake Bytes written to TLSMemoryBIOProtocol before the handshake is complete are received by the protocol on the other side of the connection once the handshake succeeds.
Method test_writeAfterLoseConnection Bytes written to TLSMemoryBIOProtocol after loseConnection is called are not transmitted (unless there is a registered producer, which will be tested elsewhere).
Method test_writeBeforeHandshake Bytes written to TLSMemoryBIOProtocol before the handshake is complete are received by the protocol on the other side of the connection once the handshake succeeds.
Method test_writeSequence Bytes written to TLSMemoryBIOProtocol with writeSequence are received by the protocol on the other side of the connection.
Method test_writeUnicodeRaisesTypeError Writing unicode to TLSMemoryBIOProtocol throws a TypeError.
Method writeBeforeHandshakeTest Run test where client sends data before handshake, given the sending protocol and expected bytes.

Inherited from TestCase:

Method __call__ Run the test. Should always do exactly the same thing as run().
Method __init__ Construct an asynchronous test case for methodName.
Method addCleanup Extend the base cleanup feature with support for cleanup functions which return Deferreds.
Method assertFailure Fail if deferred does not errback with one of expectedFailures. Returns the original Deferred with callbacks added. You will need to return this Deferred from your test case.
Method deferRunCleanups Run any scheduled cleanups and report errors (if any) to the result. object.
Method deferSetUp Undocumented
Method deferTearDown Undocumented
Method deferTestMethod Undocumented
Method getSuppress Undocumented
Method getTimeout Returns the timeout value set on this test. Checks on the instance first, then the class, then the module, then packages. As soon as it finds something with a timeout attribute, returns that. Returns util.DEFAULT_TIMEOUT_DURATION...
Instance Variable timeout A real number of seconds. If set, the test will raise an error if it takes longer than timeout seconds. If not set, util.DEFAULT_TIMEOUT_DURATION is used.
Method _cbDeferTestMethod Undocumented
Method _classCleanUp Undocumented
Method _cleanUp Undocumented
Method _deprecateReactor Deprecate iterate, crash and stop on reactor. That is, each method is wrapped in a function that issues a deprecation warning, then calls the original.
Method _ebDeferSetUp Undocumented
Method _ebDeferTearDown Undocumented
Method _ebDeferTestMethod Undocumented
Method _makeReactorMethod Create a method which wraps the reactor method name. The new method issues a deprecation warning and calls the original.
Method _run Run a single method, either a test method or fixture.
Method _runFixturesAndTest Really run setUp, the test method, and tearDown. Any of these may return defer.Deferreds. After they complete, do some reactor cleanup.
Method _undeprecateReactor Restore the deprecated reactor methods. Undoes what _deprecateReactor did.
Method _wait Take a Deferred that only ever callbacks. Block until it happens.
Instance Variable _passed Undocumented
Instance Variable _reactorMethods Undocumented
Instance Variable _timedOut Undocumented

Inherited from SynchronousTestCase (via TestCase):

Method __eq__ Override the comparison defined by the base TestCase which considers instances of the same class with the same _testMethodName to be equal. Since trial puts TestCase instances into a set, that definition of comparison makes it impossible to run the same test method twice...
Method __hash__ Undocumented
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 flushLoggedErrors Remove stored errors received from the log.
Method flushWarnings Remove stored warnings from the list of captured warnings and return them.
Method getDeprecatedModuleAttribute Retrieve a module attribute which should have been deprecated, and assert that we saw the appropriate deprecation warning.
Method getSkip Return the skip reason set on this test, if any is set. Checks on the instance first, then the class, then the module, then packages. As soon as it finds something with a skip attribute, returns that in a tuple (...
Method getTodo Return a Todo object if the test is marked todo. Checks on the instance first, then the class, then the module, then packages. As soon as it finds something with a todo attribute, returns that. Returns ...
Method mktemp Create a new path name which can be used for a new file or directory.
Method patch Monkey patch an object for the duration of the test.
Method run Run the test case, storing the results in result.
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 shortDescription Undocumented
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 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.
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.
Method _getSkipReason Return the reason to use for skipping a test method.
Method _getSuppress Returns any warning suppressions set for this test. Checks on the instance first, then the class, then the module, then packages. As soon as it finds something with a suppress attribute, returns that. ...
Method _installObserver Undocumented

Method _runCleanups Synchronously run any cleanups which have been added.
Instance Variable _cleanups Undocumented
Instance Variable _observer Undocumented
Instance Variable _parents Undocumented
Instance Variable _testMethodName Undocumented

def handshakeProtocols(self): (source)

def test_getHandle(self): (source)

TLSMemoryBIOProtocol.getHandle returns the OpenSSL.SSL.Connection instance it uses to actually implement TLS.

This may seem odd. In fact, it is. The OpenSSL.SSL.Connection is not actually the "system handle" here, nor even an object the reactor knows about directly. However, twisted.internet.ssl.Certificate's peerFromTransport and hostFromTransport methods depend on being able to get an OpenSSL.SSL.Connection object in order to work properly. Implementing ISystemHandle.getHandle like this is the easiest way for those APIs to be made to work. If they are changed, then it may make sense to get rid of this implementation of ISystemHandle and return the underlying socket instead.
