Mock adapter for unit-testing Hubot

I've whacked together a couple of Hubot scripts, but then they started getting more complicated. TDD is really the ONLY way to do any kind of meaningful development. But even if you're not TDD'ing, you are testing, right? Right?

I couldn't find an existing method for writing unit tests for Hubot scripts. After digging around under Hubot's hood, I figured out all I really needed was an Adapter implementation I could spy on. That is what you see here.

Example Usage

Let's assume you've got a really simple script, like this:

module.exports = function (robot) {
  robot.hear(/Computer!/, function (msg) {
    msg.reply("Why hello there! (ticker tape, ticker tape)");
  });
};

Node Test Runner

Create a test file in a folder. e.g. index.test.mjs.

You'll need a Node version > 17.

Assuming your tests are in test/ or have .test. before the file extension, just run node --test. For less typing, in your package.json, add a test script:

"scripts": {
  "test": "node --test"
}

Then you can use npm test to run your tests!

Mocha

Create a test file in a folder. e.g. index.js.

You'll need devDependencies something like this in your package.json:

"devDependencies": {
  "coffeescript": "^2.7.0",
  "chai": "^4.3.7",
  "hubot-mock-adapter": "^1.x.x",
  "mocha": "^10.2.0",
  "hubot": "^7.x.x",
}

Assuming your tests are in test/, just run node_modules/.bin/mocha --exit. For less typing, in your package.json, add a test script:

"scripts": {
  "test": "mocha --exit"
}

Then you can use npm test to run your tests!
