員工 model - backbone.js 的自定義方法 一個測試用例失敗
[英]Custom method for employee model - backbone.js one test case is failing
問題描述
面臨 getExperience 方法的問題。 不知道為什么我得到那個可以請任何人幫助我。 錯誤：在員工 Model 中測試自定義方法 測試員工 Model 中的 getExperience 方法正在檢查員工 Model 在 getExperience 方法執行后的經驗。
<,-- 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");;

您永遠不會為模型的experience屬性設置新值。 為了讓您的測試通過，您應該使用： expect(employee.getExperience()).toBe(calculated_exp);
請注意，您的 getExperience 函數從未使用過經驗參數。
或者替換：
employee.getExperience(employee.get('year_of_joining'));
和：
employee.set('experience', employee.getExperience());

這是backbonejs中員工model自定義方法的正確答案：
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");
