JavaScript 测试工具库：Atomus
Atomus 是一个在 JSDOM的基础上进行封装简单的工具库，用来在Node.js环境下测试客户端代码。当使用终端模拟浏览器的时候，Atomus在单元测试和功能性测试中非常有用。这就是Atomus名字的来源。Atomus会和应用程序的单元和谐工作。你只需要包含需要测试框架和模块，然后创建一个实例，然后开始使用DOM和模块的API即可。
Simple usage
All you have to do is to require the module, call the ready method:
var htmlStr = '<body><h1>Atomus</h1></body>'; var atomus = require('atomus'); var browser = atomus().html(htmlStr).ready(function(errors, window) { ... }); The window that is passed to our callback is the good old Window object that we have in every browser. Thankfully to jsdom we have a JavaScript implementation of the WHATWG DOM and HTML standards. So we may call window.document.querySelector or element.dispatchEvent. In practice we may interact with the page as we are in a real browser.
API
browser.ready([callback])- call this method when you are ready with configuring your browser. The callback receiveserrorsandwindowobject.browser.external([filepath])- add an absolute path to JavaScript file that you want to be injected into the page. This may be a framework or custom bundled JavaScript for example.browser.html([string])- the initial HTML markup of the page
Once the ready method is called we have a few other methods and objects available.
browser.$- jQuerybrowser.window- the usual Window objectbrowser.clicked([jQuery object or DOM element])- firesclickevent.browser.changed([jQuery object or DOM element])- fireschangeeventbrowser.focused([jQuery object or DOM element])- firesfocuseventbrowser.blurred([jQuery object or DOM element])- firesblureventbrowser.selected([jQuery object or DOM element])- firesclickevent. Use this while you operate with radio or checkboxes.
JSDom has some problems with radio and checkboxes selecting. That's why we introduced API methods for triggering events. For sure you may use $('#link').trigger('click') but that's not working properly in some cases. So, we recommend using browser API for dispatching DOM events.
