Jest Discord.js Mocks

A bunch of mocks that can be used in place for various discord.js classes for unit testing with Jest.

Usage

You can import the Mock classes for the discord.js class that you are trying to mock out, such as MockMessage

From there, you can set various properties and replace methods with jest.fn() calls.

Example:

import {MockMessage, MockTextChannel} from "jest-discordjs-mocks";

test("discord.js mock test", () => {
    const message = new MockMessage();
    const channel = new MockTextChannel();
    message.content = "test";
    message.channel = channel;
    callMyFunctionToTestHere(message);
    expect(message.channel.send).toHaveBeenCalled()
});

Why some classes are exported and some aren't

Jest only allows for mocking certain classes from discord.js in typescript - the rest will result in errors
