You never set new value for experience attribute of your model.您永远不会为模型的experience属性设置新值。 As it is for your test to pass you should use: expect(employee.getExperience()).toBe(calculated_exp);为了让您的测试通过，您应该使用： expect(employee.getExperience()).toBe(calculated_exp);
Note the experience argument is never used by your getExperience function.请注意，您的 getExperience 函数从未使用过经验参数。
Or replace:或者替换：
employee.getExperience(employee.get('year_of_joining'));
with:和：
employee.set('experience', employee.getExperience());

Here is correct answer for custom method for employee model in backbonejs:这是backbonejs中员工model自定义方法的正确答案：
var Employee = Backbone.Model.extend({ //Write your code here getExperience: function(year_of_joining) { var current_date = new Date(); var current_year = current_date.getFullYear(); var calculated_exp = (current_year) - (year_of_joining); this.set({ experience: calculated_exp }); 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");
