jQuery Test Suite

jQuery Test Suite

With jQuery Test Suite (jts) it's possible to do unit test for javascript. There are other libraries (e.g. JsUnit), but as we already use jQuery, this is the obvious choice.

Usage

A jts consists of a html-file and a set of javascript test files.

html

The html-file includes the test scripts, together with the jQuery- and testrunner-libraries (+ a css file for styling). it also contains the necessary markup for the tests to run on, and a container for the results.
The following markup file can be used as a template: template.html (text/html, 817 bytes, info).

js test file

module('moduleName') is called on start of module test to prepend the module name to all tests. The tests itselves are contained in a test('testName', function)-method.

Example:

module("Module A");

test("Basic tests", function() {
    expect(2);
    ok( true, "This asserts to true" );
    equals( "abc", "a" + "b" + "c", "These 2 things are equal" );
});

API

Method	Description
expect(asserts)	Specify the number of expected assertions to guarantee that failed test (no assertions are run at all) don't slip through.
reset()	Resets the test setup. Useful for tests that modify the DOM.
ok(a, msg)	Asserts true.
isSet(a, b, msg)	Asserts that two arrays are the same
isObj(a, b, msg)	Asserts that two objects are equivalent
equals(actual, expected, message)	Checks that the first two arguments are equal, with an optional message. Prints out both expected and actual values on failure. Preferred to ok( expected == actual, message )
