单元测试角度分页

Question

我在我的标头中使用它来获取所有数据，我在我的控制器中解析 (toJson) 标头：

X-Pagination:{"current_page":1,"per_page":10,"total_pages":16,"sub_count":10,"total_count":159}

var parsingHeader = angular.fromJson(vms.headers('X-Pagination'));
          _this.current_page = parsingHeader.current_page;
          _this.per_page = parsingHeader.per_page;
          _this.total_pages = parsingHeader.total_pages;
          _this.total_count = parsingHeader.total_count;

我想测试一下：

$httpBackend
      .whenGET('http://localhost:3000/vms.json?page=1')
      .respond(function(method, url, data, headers){
        ...
      });

我有一些错误： “null”不是对象（正在评估“parsingHeader.current_page”），...
测试这个的最佳过程是什么？

您需要将标头 X-Pagination:{"current_page":1,"per_page":10,"total_pages":16,"sub_count":10,"total_count":159} 传递给您的 whenGET。我看到没有标题通过，这就是为什么 parsingHeader 变量为空

做这样的事情：

$httpBackend
      .whenGET('http://localhost:3000/vms.json?page=1', ['X-Pagination':{"current_page":1,"per_page":10,"total_pages":16,"sub_count":10,"total_count":159}] )
      .respond(function(method, url, data, headers){
        ...
      });
