Question

我正在设置我的SpecRunner.html / .js，RequireConfig.js，我的路径和垫片，就像我早期发布的Jasmine + RequireJs候选版本一样，但现在我的测试方法显示Jasmine未定义。他们最近改用了另一种加载Jasmine的方法，据我所知，它与RequireJs不兼容。

我的理解是否正确？如果是这样，我们是否能够再次使用Jasmine + RequireJs？

Answer 1

新的boot.js做了一堆初始化并将它附加到window.onload（），它已被require.js加载Jasmine时调用。您可以手动调用window.onload（）来初始化HTML Reporter并执行环境。

SpecRunner.html

<!doctype html>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Jasmine Spec Runner v2.0.0</title>

    <link rel="shortcut icon" type="image/png" href="lib/jasmine-2.0.0/jasmine_favicon.png">
    <link rel="stylesheet" type="text/css" href="lib/jasmine-2.0.0/jasmine.css">

    <!-- specRunner.js runs all of the tests -->
    <script data-main="specRunner" src="../bower_components/requirejs/require.js"></script>
  </head>
  <body>
  </body>
</html>

specRunner.js

(function() {
  'use strict';

  // Configure RequireJS to shim Jasmine
  require.config({
    baseUrl: '..',
    paths: {
      'jasmine': 'tests/lib/jasmine-2.0.0/jasmine',
      'jasmine-html': 'tests/lib/jasmine-2.0.0/jasmine-html',
      'boot': 'tests/lib/jasmine-2.0.0/boot'
    },
    shim: {
      'jasmine': {
        exports: 'window.jasmineRequire'
      },
      'jasmine-html': {
        deps: ['jasmine'],
        exports: 'window.jasmineRequire'
      },
      'boot': {
        deps: ['jasmine', 'jasmine-html'],
        exports: 'window.jasmineRequire'
      }
    }
  });

  // Define all of your specs here. These are RequireJS modules.
  var specs = [
    'tests/spec/routerSpec'
  ];

  // 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();
    });
  });
})();

示例规范

define(['router'], function(router) {
  'use strict';

  describe('router', function() {
    it('should have routes defined', function() {
      router.config({});
      expect(router.routes).toBeTruthy();
    });
  });
});

这是一种替代方法，在某些情况下可能更简单 - 在执行测试之前使用Jasmine's asynchronous support加载AMD模块，如下所示：

MySpec.js ：

中的

describe('A suite', function() {
  var myModule;

  // Use require.js to fetch the module
  it("should load the AMD module", function(done) {
    require(['myModule'], function (loadedModule) {
      myModule = loadedModule;
      done();
    });
  });

  //run tests that use the myModule object
  it("can access the AMD module", function() {
    expect(myModule.speak()).toBe("hello");
  });
});

为了实现这一点，您需要在SpecRunner.html中包含require.js，并且可能需要configure require（通常情况下可以设置baseUrl），如下所示：

SpecRunner.html ：

中的

<!DOCTYPE HTML>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Jasmine Spec Runner v2.0.0</title>

    <link rel="shortcut icon" type="image/png" href="lib/jasmine-2.0.0/jasmine_favicon.png">
    <link rel="stylesheet" type="text/css" href="lib/jasmine-2.0.0/jasmine.css">

    <script src="lib/require.min.js"></script>
    <script> require.config({ baseUrl: "src" }); </script>

    <script src="lib/jasmine-2.0.0/jasmine.js"></script>
    <script src="lib/jasmine-2.0.0/jasmine-html.js"></script>
    <script src="lib/jasmine-2.0.0/boot.js"></script>

    <script src="spec/MySpec.js"></script>

  </head>
  <body>
  </body>
</html>

对于此示例，AMD模块实现可能如下所示：

src / myModule.js ：

中的

define([], function () {
  return {
    speak: function () {
      return "hello";
    }
  };
});

这是working Plunk that implements this complete example。

享受！

Jasmine 2.0真的不适用于require.js吗？
