Prerequisites

• ID of a discord guild to test in
• The token of a bot application with admin rights on this guild
• If you want to test a bot it should be running in a seperate process

For more information take a look at the setup FAQ.

Getting started

Install

from npm or gpr with

npm install --save-dev @vocality-org/discord-listen

Examples

Responses

Basic

import { ResponseClient } from '@vocality-org/discord-listen';

const client = await new ResponseClient().setup(
    '[TEST_GUILD_ID]',
    '[TEST_BOT_TOKEN]'
);

client.write('!ping').then(response => {
    console.log(response.content); // pong
});

In the discord client this will look like:

Mocha command test

A mocha test for a command of your discord bot could look like this.

import assert from 'assert';
import { ResponseClient } from '@vocality-org/discord-listen';

const options = {
    messagePrefix: '!',
    specificUserId: '[YOUR_BOT_ID]',
    responseTimeout: 3000
};

let client;

before(async () => {
    client = await new ResponseClient(options).setup('[TEST_GUILD_ID]', '[TEST_BOT_TOKEN]');
});

describe('ping', function () => {
    this.timeout(options.responseTimeout);    // mochas default timeout is 2s

    it('should respond with correct message', done => {
        client.write('ping').then(response => {
            assert.equal(response.content, 'pong');
            done();
        });
    });
});

after(async () => {
    await client.cleanup();
});

Mocking

Message Object

import { MockClient } from '@vocality-org/discord-listen';

const mock = await new MockClient().setup(
    '[YOUR_GUILD_ID]',
    '[YOUR_BOT_TOKEN]'
);

const message = await mock.message('message content');

Options

const opts = {
    /**
