To access the test cases, start the server using the settings file **jasmine.py** using this command:

All the JavaScript codes must have test coverage. Both CMS and LMS
has its own test directory in `{cms,lms}/static/coffee/spec` If you haven't

sure how to test, please feel free to open up a pull request and asking people
for help. (However, the best way to do it would be writing your test first, then
implement your feature - Test Driven Development.)
### BDD style acceptance tests with Lettuce
We're using Lettuce for end user acceptance testing of features.
More info [on the wiki](https://edx-wiki.atlassian.net/wiki/display/ENG/Lettuce+Acceptance+Testing)
Lettuce is a port of Cucumber. We're using it to drive Splinter, which is a python wrapper to Selenium.
To execute the automated test scripts, you'll need to start up the django server separately, then launch the tests.
Do both use the settings file named **acceptance.py**.
What this will do is to use a sqllite database named mitx_all/db/test_mitx.db.
That way it can be flushed etc. without messing up your dev db.
Note that this also means that you need to syncdb and migrate the db first before starting the server to initialize it if it does not yet exist.
1. Set up the test database (only needs to be done once):
rm ../db/test_mitx.db
rake django-admin[syncdb,lms,acceptance,--noinput]
rake django-admin[migrate,lms,acceptance,--noinput]
2. Start up the django server separately in a shell
rake lms[acceptance]
3. Then in another shell, run the tests in different ways as below. Lettuce comes with a new django-admin command called _harvest_. See the [lettuce django docs](http://lettuce.it/recipes/django-lxml.html) for more details.
* All tests in a specified feature folder: `django-admin.py harvest --no-server --settings=lms.envs.acceptance --pythonpath=. lms/djangoapps/portal/features/`
* Only the specified feature's scenarios: `django-admin.py harvest --no-server --settings=lms.envs.acceptance --pythonpath=. lms/djangoapps/courseware/features/high-level-tabs.feature`
4. Troubleshooting
* If you get an error msg that says something about harvest not being a command, you probably are missing a requirement. Pip install (test-requirements.txt) and/or brew install as needed.

## acceptance_testing
This fake django app is here to support acceptance testing using <a href="http://lettuce.it/">lettuce</a> +
<a href="http://splinter.cobrateam.info/">splinter</a> (which wraps <a href="http://selenium.googlecode.com/svn/trunk/docs/api/py/index.html">selenium</a>).
First you need to make sure that you've installed the requirements.
This includes lettuce, selenium, splinter, etc.
Do this with:
```pip install -r test-requirements.txt```
The settings.py environment file used is named acceptance.py.
It uses a test SQLite database defined as ../db/test-mitx.db.
You need to first start up the server separately, then run the lettuce scenarios.
Full documentation can be found on the wiki at <a href="https://edx-wiki.atlassian.net/wiki/display/ENG/Lettuce+Acceptance+Testing">this link</a>.
