我发现运行通常会打开您在单元测试Ext.application期间通常不需要的视图- 否则您会冒险进行集成测试，因此我避免使用 Sencha 开发加载程序。相反，我使用 Karma 来加载单元测试和应用程序类文件。您在文件中配置这些文件（下面的示例）。karma.conf.js
我改编了来自 Pivotal Labs 的优秀单元测试教程中的示例。由于 Karma 有一个内置的 Web 服务器，因此您不需要 Rails、Rake 或 pow，正如他们的第一个教程所述。使用 Karma 意味着您可以轻松地将单元测试与 IntelliJ IDEA 或 WebStorm 等 Javascript 工具以及https://saucelabs.com/等 CI 系统和云测试集成。您还可以将其配置为监视您的代码文件并在更新它们时自动重新运行单元测试。您还可以使用它karma-istanbul来执行代码覆盖率分析。
使用我在这里学到的技巧，我运行了一个setup.js在我的文件中配置的karma.conf.js文件，以便在单元测试之前加载。它创建了一个虚假的应用程序对象，以便控制器可以将自己分配给应用程序实例，并且它故意没有launch()方法。它还包括来自 Pivotal Labs 示例的 SpecHelper.js 代码。
// Create (but don't launch) the app
Ext.application({name: 'MyAppName' });
对于视图单元测试问题，您可以创建一个伪造的Ext.Viewport对象并添加一个 spyOn().andReturn() 来伪造Ext.Viewport.getOrientation()测试期间视图所需的方法。这意味着您的单元测试可以轻松涵盖两种方向情况。您还可以renderTo:在测试期间添加一个属性来检查呈现的视图：
describe("when portrait orientation", function() {
var view;
beforeEach(function () {
if (!Ext.Viewport) Ext.Viewport = {};
spyOn(Ext.Viewport, 'getOrientation').andReturn('portrait');
view = Ext.create('MyAppName.view.LoginView', {
renderTo: 'jasmine_content'
}
}
it("should render large image", function() {
expect(Ext.DomQuery.select('...')).toContain('img/login.png');
});
it("should render 80px style", function() {
expect(Ext.DomQuery.select('...')).toContain('80px');
});
});
查看单元测试（解释如何使用该renderTo属性）。
我的setup.js文件如下所示，包括SpecHelper.js此处显示的代码。您需要这个才能使用该renderTo 属性。
控制器单元测试涵盖了如何将控制器连接到您的假应用程序实例。
setup.js这段代码从这里
窃取了一个 Karma 加载技巧，但与他们的示例不同，它避免使用开发加载程序。
Ext.Loader.setConfig({
enabled: true, // Turn on Ext.Loader
disableCaching: false // Turn OFF cache BUSTING
});
// 'base' is set by Karma to be __dirname of karm.conf.js file
Ext.Loader.setPath({
'Ext': 'base/touch/src',
'MyAppName': 'base/app'
});
// Create (but don't launch) the app
Ext.application({name: 'MyAppName' });
Ext.require('Ext.data.Model');
afterEach(function () {
Ext.data.Model.cache = {}; // Clear any cached models
});
var domEl;
beforeEach(function () { // Reset the div with a new one.
domEl = document.createElement('div');
domEl.setAttribute('id', 'jasmine_content');
var oldEl = document.getElementById('jasmine_content');
if (oldEl) oldEl.parentNode.replaceChild(domEl, oldEl);
});
afterEach(function () { // Make the test runner look pretty
domEl.setAttribute('style', 'display:none;');
});
// Karma normally starts the tests right after all files specified in 'karma.config.js' have been loaded
// We only want the tests to start after Sencha Touch/ExtJS has bootstrapped the application.
// 1. We temporary override the '__karma__.loaded' function
// 2. When Ext is ready we call the '__karma__.loaded' function manually
var karmaLoadedFunction = window.__karma__.loaded;
window.__karma__.loaded = function () {};
Ext.onReady( function () {
console.info("Starting Tests ...");
window.__karma__.loaded = karmaLoadedFunction;
window.__karma__.loaded();
});
