A test-driven JS assessment

This repo includes a set of tests that can be used to assess the skills of a candidate for a JavaScript position, or to improve one's own skills.

I want to work on the tests; what do I do?

To use the tests, you will need to install Node -- you can do this via the download page or using Homebrew if you are on a Mac.

Note that on Windows, there are some reports that you will need to restart after installing Node - see #12.

You can clone or download this repo. Once you have done so, from the root directory of the repo, run:

npm install
node bin/serve

You can then view the tests in your browser at http://localhost:4444.

When you visit that page, all of the tests should be failing; your job is to get the tests to pass. To do this, you'll need to edit the files in the tests/app directory. The tests have inline comments that should point you in the right direction; once you update a test, you can reload the test page in the browser to see whether it worked.

I want to contribute tests; what do I do?

Submit a pull request! The tests are currently loosely organized by topic, so you should do your best to add tests to the appropriate file in tests/app, or create a new file there if you don't see an appropriate one. If you do create a new file, make sure to add it to tests/runner.js.

Any substantial contributions will be duly credited in the readme, as well as of course in the git commit log.

Data-driven tests

If your tests need data that can be fetched via XHR, stick a .json file in the data directory; you can access it at /data/<filename>.json.

Available dependencies

The repo includes Backbone, Underscore, and RequireJS. If there's other stuff you'd find useful, you can put it in the lib directory.

I want to see the answers!

I haven't worked out how best to show the answers, or whether to show them at all. For now, if you're stuck, the tests themselves should include enough keywords that your friendly neighborhood search engine can point you in the right direction.

I hate <some technology you've chosen>

This repo uses RequireJS for dependency management and Mocha and expect.js for the tests themselves. It uses the BDD style for authoring tests. If this doesn't suit you, please fork away, or, better, submit a pull request that lets this be more flexible than it currently is.
