ImpactTest

ImpactTest is a wrapper for Nodeunit, providing a system for building unit tests in Node.js for your Impact.js game.

Usage

Basic Tests

Here is an example test file:

var ig = require('impact').ig;

ig._testRequire('game.main');

exports['test something'] = ig.test(function (test) {
    test.ok(true, 'this assertion will pass');
    test.done();
});

exports['test another thing'] = ig.test(function (test) {
    test.ok(false, 'this assertion will fail');
    test.done();
});

Groups, SetUp, and TearDown

Using ig.testCase will allow you to specify custom setUp and tearDown methods that will be run before and after each test case in the group.

var ig = require('impact').ig;

ig._testRequire('game.main');

exports.MyGame = ig.testCase({
    setUp: function (callback) {
        this.foo = 'bar';
        callback();
    },

    tearDown: function (callback) {
        // do any cleanup here
        callback();
    },

    'my test': function (test) {
        test.equals(this.foo, 'bar');
        test.done();
    }
});
