Script.aculo.us Behaviour Driven Development Testing
<>p>Thomas Fuchs has added some new features to the script.aculo.us test library that borrow from Behaviour Driven Development.JAVASCRIPT:
-
-
Test.context("BDD-style testing",{
-
'should automatically add extensions to strings': function(){
-
'a'.shouldEqual('a');
-
'a'.shouldNotEqual('b');
-
'a'.shouldNotBeNull();
-
'a'.shouldBeA(String);
-
'a'.shouldNotBeA(Number);
-
}
-
});
-
Basically, you’re defining a context for which one or more specifications should be asserted. Note the easy readability, and the added value by using a string to describe the test/specification, giving you the advantage of having better documentation for your JavaScript libraries.
Of course, setup and teardown is also supported, as are all normal assert* methods.
This appears to have made it into the recent Prototype changes too.

Currently(v1.7.1b3), script.aculo.us BDD framework doesn’t support IE. But it can be easily fixed. Just edit line 530 from this:
‘function(){‘+
to this:
‘x = function(){‘+
I hope it will help.
