AngularJS / Karma – 指令中的单元测试函数

2023年11月30日 138次阅读

如何在指令的链接中单元测试函数？我试过这样的事,但没有奏效：

指示：

app.directive("hello", function(){
  return {
    link: function(scope){
      scope.hello = function(){
        return "hello";
      };
    }
  };
});

单元测试：

describe("Hello directive", function(){
  var compile, scope;

  beforeEach(inject(function($compile, $rootScope){
    scope = $rootScope.$new();
    compile = $compile;
  }));

  it("should return hello", function(){
    var element = compile("<hello></hello>")(scope);
    expect(element.scope.hello()).toBe("hello");
  });
});

最佳答案 您缺少对模块的调用.

指令限制看起来很好(现在),因为默认值是根据angular source for $compileProvider的’EA’.

Note: Said default was introduced in angular-1.3.0(07001, 07002), prior to that version it was simply 'A'. Which would have been an issue in your case, seeing as how your question was posted in May’14.

我设置了一个小提示,通过两个更改来展示您的实现;

>调用模块,以便加载指令定义.
>将角度版本归为1.3.0.

是的,我迟到了,但你的问题仍然是[angularjs] [单元测试]中最难回答的问题之一.我想我会改变它.
