使用Jasmine和RequireJS的Squire.js示例
使用Jasmine和RequireJS的Squire.js示例
提问于 2013-09-30 16:19:26
我想写JS测试。生产代码是用RequireJS编写的。我找到了一个名为Squire.js：https://github.com/iammerrick/Squire.js/的测试库
来自Squire.js网站
Run生成一个函数，该函数将接收完成的回调，并在测试函数完成后执行它。对于使用回调处理异步的框架特别有用。下面是一个使用Mocha.js的示例。Jasmine可以使用Jasmin.Async提供这种回调方法。“
我不知道如何将此与Jasmine async一起使用。一个小的例子会非常有用。

这是一个很好的设置，用于将带有模拟依赖项的模块插入到测试中。这是一个端到端的示例，如果您只想查看规范，请跳到最后。
文件夹结构：
Jasmine
|-lib
||-jasmine -- Contains all the Jasmine files
|||-boot.js
|||-jasmine-html.js
|||-jasmine.js
|||-jasmine.css
|||-jasmine_favicon.png
|||-...
|-spec -- Spec files go here
||-hello-spec.js
|SpecRunner.html
|SpecRunner.js
|squire.js
Scripts
|knockout.js
|require.js
|jquery.js
App
|-hello.js
|-foo.js在您提出问题时，Jasmine 1.3是最新版本。从那时起，2.0发布了，并包含了一些异步改进。这两个版本都在这里，1.3被注释掉了。
SpecRunner.html:

这个问题Does Jasmine 2.0 really not work with require.js?对启动和运行它很有帮助。
(function () {
'use strict';
// Configure RequireJS to shim Jasmine
requirejs.config({
baseUrl: "../App",
paths: {
'jasmine' : '../Jasmine/lib/jasmine/jasmine',
'jasmine-html': '../Jasmine/lib/jasmine/jasmine-html',
'boot': '../Jasmine/lib/jasmine/boot', // This is not present in Jasmine 1.3
'spec' : '../Jasmine/spec',
'squire': '../Jasmine/squire',
'knockout': '../Scripts/knockout-2.3.0',
'jquery': '../Scripts/jquery-1.10.2' // This only used in the Jasmine 1.3 case.
},
shim: {
'jasmine': {
exports: 'jasmine'
},
'jasmine-html': {
deps: ['jasmine'],
exports: 'jasmine'
},
'boot': {
deps: ['jasmine', 'jasmine-html'],
exports: 'jasmine'
},
"squire": {
exports: "squire"
}
}
});
// Define all of your specs here. These are RequireJS modules.
var specs = [
'spec/hello-spec'
];
// Load Jasmine - This will still create all of the normal Jasmine browser globals unless `boot.js` is re-written to use the
// AMD or UMD specs. `boot.js` will do a bunch of configuration and attach it's initializers to `window.onload()`. Because
// we are using RequireJS `window.onload()` has already been triggered so we have to manually call it again. This will
// initialize the HTML Reporter and execute the environment.
require(['boot'], function () {
// Load the specs
require(specs, function () {
// Initialize the HTML Reporter and execute the environment (setup by `boot.js`)
window.onload();
});
});
/******

//require(['jquery', 'jasmine-html'], function ($, jasmine) {
// var jasmineEnv = jasmine.getEnv();
// jasmineEnv.updateInterval = 1000;
// var htmlReporter = new jasmine.HtmlReporter();
// jasmineEnv.addReporter(htmlReporter);
// jasmineEnv.specFilter = function(spec) {
// return htmlReporter.specFilter(spec);
// };
// $(function() {
// require(specs, function(spec) {
// jasmineEnv.execute();
// });
// });
//});
// end 1.3
})();foo.js:
define(['knockout'], function (ko) {
var message = ko.observable("Go away, World!");
return {
message: message()
};
});hello.js:
define(['foo'], function (foo) {
return {
message : foo.message
};
});hello-spec.js:
define(['squire'], function (Squire) {
var injector = new Squire();
var builder = injector
.mock('foo', {
message: "Hello, World!"
});
describe('hello', function () {
var hello;
beforeEach(function (done) {
// For async:
// accept a "done" parameter and Jasmine will wait...
builder.require(['hello'], function (hi) {
hello = hi;
done(); // ...until you invoke it.
});
/*******
* Use the following if you're on 1.3
*********/
//var done;
//runs(function () {
// builder.require(['hello'], function (hi) {
// hello = hi;
// done = true;
// });
//});
//waitsFor(function () {
// return done;
//}, "Unable to load dependency not loaded", 750);
// end 1.3
});
it('is welcoming', function() {
expect(hello.message).toBe("Hello, World!");
});
});
describe('hello no mock foo', function () {
var hello;
beforeEach(function (done) {
// For async:
// accept a "done" parameter and Jasmine will wait...
require(['hello'], function (hi) {
hello = hi;
done(); // ...until you invoke it.
});
/*******

// end 1.3
});
it('is less than welcoming', function () {
expect(hello.message).toBe("Go away, World!");
});
});
});详细信息
线条
var injector = new Squire();
var builder = injector
.mock('foo', {
message: "Hello, World!"
});模拟hello对foo的依赖，然后
builder.require(['hello'], function (hi) {
hello = hi;
done(); // ...until you invoke it.
});使用模拟的foo加载hello模块。与在第二个测试中使用require本身加载hello进行比较：
require(['hello'], function (hi) {
hello = hi;
done(); // ...until you invoke it.
});Jasmine文档http://jasmine.github.io/可以填写“完成()”功能(2.0)或“运行/等待”(1.3)。
