员工 model - backbone.js 的自定义方法 一个测试用例失败
[英]Custom method for employee model - backbone.js one test case is failing
问题描述
面临 getExperience 方法的问题。 不知道为什么我得到那个可以请任何人帮助我。 错误：在员工 Model 中测试自定义方法 测试员工 Model 中的 getExperience 方法正在检查员工 Model 在 getExperience 方法执行后的经验。
<,-- 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。 为了让您的测试通过，您应该使用： expect(employee.getExperience()).toBe(calculated_exp);
请注意，您的 getExperience 函数从未使用过经验参数。
或者替换：
employee.getExperience(employee.get('year_of_joining'));
和：
employee.set('experience', employee.getExperience());

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");
