Backend

Module for ‘server-side’ state during testing. This module should contain methods for altering said server-side state, which then are responsible for triggering a parse_* call in the configured client state to inform the bot of the change.

This setup matches discord’s actual setup, where an HTTP call triggers a change on the server, which is then sent back to the bot as an event which is parsed and dispatched.

class BackendState(messages: Dict[int, List[Dict[str, str | int | bool | Dict[str, JsonVal] | List[JsonVal]]]], state: FakeState)

The dpytest backend, with all the state it needs to hold to be able to pretend to be discord. Generally only used internally, but exposed through get_state()

messages: Dict[int, List[Dict[str, str | int | bool | Dict[str, JsonVal] | List[JsonVal]]]]

Alias for field number 0

state: FakeState

Alias for field number 1

__slots__ = ()

class FakeRequest(status: int, reason: str)

A fake web response, for use with discord HTTPExceptions

status: int

Alias for field number 0

reason: str

Alias for field number 1

__slots__ = ()

class FakeHttp(loop: AbstractEventLoop | None = None)

A mock implementation of an HTTPClient. Instead of actually sending requests to discord, it triggers a runner callback and calls the dpytest backend to update any necessary state and trigger any necessary fake messages to the client.

fileno: ClassVar[int] = 0

__init__(loop: AbstractEventLoop | None = None) → None

state: FakeState

async request(*args: Any, **kwargs: Any) → NoReturn

Overloaded to raise a NotImplemented error informing the user that the requested operation isn’t yet supported by dpytest. To fix this, the method call that triggered this error should be overloaded below to instead trigger a callback and call the appropriate backend function.

Parameters:

• args – Arguments provided to the request

• kwargs – Keyword arguments provided to the request
