twisted.test.proto_helpers : API documentation

Class	AccumulatingProtocol	`AccumulatingProtocol` is an `IProtocol` implementation which collects the data delivered to it and can fire a Deferred when it is connected or disconnected.
Class	LineSendingProtocol	Undocumented
Class	FakeDatagramTransport	Undocumented
Class	StringTransport	A transport implementation which buffers data in memory and keeps track of its other state without providing any behavior.
Class	StringTransportWithDisconnection	A `StringTransport` which can be disconnected.
Class	StringIOWithoutClosing	A BytesIO that can't be closed.
Class	_FakePort	A fake `IListeningPort` to be used in tests.
Class	_FakeConnector	A fake `IConnector` that allows us to inspect if it has been told to stop connecting.
Class	MemoryReactor	A fake reactor to be used in tests. This reactor doesn't actually do much that's useful yet. It accepts TCP connection setup attempts, but they will never succeed.
Class	MemoryReactorClock	Undocumented
Class	RaisingMemoryReactor	A fake reactor to be used in tests. It accepts TCP connection setup attempts, but they will fail.
Class	NonStreamingProducer	A pull producer which writes 10 times only.
Function	waitUntilAllDisconnected	Take a list of disconnecting protocols, callback a `Deferred` when they're all done.

def waitUntilAllDisconnected(reactor, protocols): (source)

Take a list of disconnecting protocols, callback a Deferred when they're all done.

This is a hack to make some older tests less flaky, as ITransport.loseConnection is not atomic on all reactors (for example, the CoreFoundation, which sometimes takes a reactor turn for CFSocket to realise). New tests should either not use real sockets in testing, or take the advice in https://jml.io/pages/how-to-disconnect-in-twisted-really.html to heart.

Parameters	reactor	The reactor to schedule the checks on. (type: `IReactorTime`)
	protocols	The protocols to wait for disconnecting. (type: A `list` of `IProtocol`s.)
