unit-testing - 使用 RequireJS、Jasmine 和测试的 JavaScript 依赖注入(inject)

Question

我只是在使用 RequireJS 和 Jasmine 的单元测试策略中寻找依赖注入(inject)。我真的很喜欢 testr 背后的想法我尝试按照 github 中的示例设置 testr，但我不知道出了什么问题。我总是得到错误

Error: module has not been loaded: today

当 testr 尝试加载要测试的模块时。

这里有一些上下文..

index.html
..

<script data-main="config" src="../../assets/js/libs/require.js"></script>
<script src="vendor/testr.js"></script>

config.js
..

require.config({

  // Initialize specs.
  deps:["main"],
...
...
});

main.js
..

require([
  // Load the example spec, replace this and add your own spec
  "spec/today"
], function() {
  var jasmineEnv = jasmine.getEnv();
  jasmineEnv.execute();
});

规范\today.js
..

describe('Today print', function() {
  var date = {}, today;
  beforeEach(function() {
     date.today = new Date(2012, 3, 30);
     today = testr('today', {'util/date': date});  //Here is where the error is thrown
  });

  it('is user-friendly', function() {
     expect(today.getDateString()).toBe('Today is Monday, 30th April, 2012');
  });
});

今天.js
..

define(['string', 'util/date'], function(string, date) {
  return {
    getDateString: function() {
      return string.format('Today is %d', date.today);
    }
  }
});

有没有人遇到过同样的问题？ .我正在使用 RequireJS 2.0.6

谢谢。

您的“今天”模块需要先从 requirejs 加载，然后才能用于测试。
尝试类似:

require(['today'], function(){
    describe('Today print', function() {
      var date = {}, today;
      beforeEach(function() {
         date.today = new Date(2012, 3, 30);
         today = testr('today', {'util/date': date});  //Here is where the error is thrown
      });

      it('is user-friendly', function() {
         expect(today.getDateString()).toBe('Today is Monday, 30th April, 2012');
      });
    });
});
