Ok! Codez!
my_awesome_page_spec.js
describe("my_awesome_page", function() {
beforeEach(function() {
loadFixtures("awesome.html");
});
describe("#change_status(status)", function() {
it("should change the status message", function() {
expect($('div#awesome').text()).toNotEqual("Awesome!");
change_status('Awesome!');
expect($('div#awesome').text()).toEqual("Awesome!");
});
});
});

Cool things
-
The jasmine-jquery helper adds nice matchers for jQuery
-
(e.g. toBe(jQuerySelector), toHaveClass(className))
-
You can slot in any js libraries and use them in your tests.
-
It works with Coffeescript
-
You can debug the js env in the browser console on Jasmine's test server page
Questions???
