员工模型的自定义方法-bone.js一个测试用例失败

如何解决员工模型的自定义方法-bone.js一个测试用例失败

getExperience方法遇到的问题。不知道为什么即时通讯可以在这方面帮助我。错误：在员工模型中测试自定义方法测试员工模型的getExperience方法在执行getExperience方法执行失败后检查员工模型中的经验失败预期0为21。

<!-- Test Case-->

  it('Checking experience in Employee Model after getExperience method execution',function() {
            var current_date = new Date();
            var current_year= current_date.getFullYear();
            var calculated_exp= current_year-1999;
              employee.getExperience(employee.get('year_of_joining'));
              expect(employee.get('experience')).toBe(calculated_exp);
          });

var Employee = Backbone.Model.extend({
 //Write your code here
 getExperience: function(experience) {
       var year_of_joining=employee.get('year_of_joining');
        var current_date = new Date();
            var current_year= current_date.getFullYear();
            var calculated_exp= (current_year)-(year_of_joining);
            return calculated_exp;
    }
});
var   employee = new Employee({
        employee_id:1111,name:'Sarah Roe',year_of_joining:1999,address:'ABC Street',experience:0
    });
    alert("Experience of "+employee.get("name")+" is "+employee.getExperience(employee.get('year_of_joining'))+" years");;

您永远不会为模型的experience属性设置新值。由于要通过测试，因此您应该使用： expect(employee.getExperience()).toBe(calculated_exp);

请注意，您的getExperience函数永远不会使用experience参数。

或替换：

employee.getExperience(employee.get('year_of_joining'));

具有：

employee.set('experience',employee.getExperience());
