# Javascript Developer Plugin

This plugin makes it easy to do TDD and/or BDD Javascript development.  
Included  
are generators to facilitate building Javascript tests and applications,  
along with  
Rake tasks for easily running these tests in a browser of your choice.

Many thanks to the javascript\_test plugin. If you want  
[Script.taculo.us](http://Script.taculo.us)’s  
unittest.js,  
then please go use this plugin. I’ve taken it and converted to use  
JSUnit.

== Generators ==

- js\_class / js\_file

These generators accept relative paths as well as plain class names, so

script/generate js\_class my\_js\_app/my\_class

will produce:

```
create public/javascripts/
create test/javascripts/unit/my_js_app
create public/javascripts/my_js_app/my_class.js
create test/javascripts/unit/my_js_app/my_class_test.html

```

There’s only a slight difference from js\_class and js\_file: js\_class  
gives  
you an  
Object template, while js\_file gives you an empty .js file.

== Rake tasks ==

rake test:javascripts - Runs all javascript tests

This task takes a couple of command-line arguments:

- KEEP\_ALIVE=true will keep the test server up for current development  
use

- BROWSER=[browser name] lets you select which browser to run the tests  
under:
