用于从指令的内部控制器访问值的单元测试设置



我正在测试一个隔离指令,该指令作为内部控制器和控制器中使用的指令范围值。

这是一个傻瓜http://plnkr.co/edit/r91xk1?p=preview实际代码是网格的指令包装器,但这显示了问题。

未通过的测试除外:

    beforeEach(inject(function($rootScope, $controller, $compile) {
      $compile = $compile;
      $scope = $rootScope.$new();
      //Here is the scope information defined, what we want to get into the directive
      $scope.itemToTest = "-beforeTest filled in valueFromTest--"
      // Here we declare that the "itemToTest" attribute is bound to the *value* of itemToTest
      elm = angular.element('<primary-grid itemToTest="itemToTest" ></primary-grid>');
      e = $compile(elm)($scope);
      $scope.$digest();
      console.log("in beforeEach $scope %o ", $scope.$id);
  }));

  it('should have filled in the value the grid', function() {
      // Access the isolateScope using <ELEMENT>.isolateScope, to see what's happening inside
      //This fails
      console.log("in Test e.scope() %o ", e.scope());
      console.log("in Test e.isolateScope() %o ", e.isolateScope().$id);
      console.log("in Test e.isolateScope().itemToTest %o ", e.isolateScope().itemToTest);
      console.log("in Test e  %o ", e);
      //This Test fails
      expect(e.isolateScope().itemToTest).toEqual($scope.itemToTest);
  }) 

关于在测试中设置指令正确值的最佳方法是什么,以便控制器可以使用它,代码可以测试单元,有什么想法吗?

感谢

解决:需要使用"item to test"作为标记中的属性,而不是camelBase(即JS)名称

用途:

elm = angular.element('<primary-grid item-to-test="itemToTest" ></primary-grid>’);

而不是:

elm = angular.element('<primary-grid itemToTest="itemToTest" ></primary-grid>’);
