Tests

=====

4+
The tests for Aurora are written using the [QUnit](http://qunitjs.com/) testing framework. They
5+
run in both Node.js and the browser.
6+
7+
##Setup
8+
9+
First, you'll need the test data, so init your git submodules to download them, and update them
10+
if you've already downloaded them before.
11+
12+
git submodule init
13+
git submodule update
14+
15+
Running the tests requires running an HTTP server to host both QUnit itself (for the browser),
16+
as well as the test data files as used by both the browser and Node to test HTTP loading.
17+
18+
To start a simple static HTTP server in the tests directory, run the following command:
19+
20+
python -m SimpleHTTPServer
21+
22+
If you already have the test directory on an HTTP server, all you need to do is set the base URL of
23+
the "tests" folder to the `HTTP_BASE` variable in `config.coffee`.
24+
425
## To run in the browser:
5-
1. Start servers to host Aurora and the tests:
26+
1. Follow the setup steps above.
27+
2. Start servers to host Aurora and the tests themselves:

importer ../browser.coffee -p 3030
830
importer test.coffee -p 3031
931
1032
You may need to install `importer` using `npm install importer -g` first.
11-
2. Open `test.html` in your browser.
33+
34+
3. Open `test.html` in your browser, using the HTTP server that you set up above.

## To run in Node:
14-
1. Either run `importer test.coffee`
15-
2. Or `npm test` from the root directory.
37+
1. Follow the setup steps above.
