单元测试服务层

本文介绍了单元测试服务层的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 你好我是单位测试我的服务层： 我有一个名为CustomerService的服务层 public interface ICustomerService { IQueryable< Customer> GetCustomerByFilter（Expression< Func< Customer，bool>> where ）; } public class CustomerService：ICustomerService { private IRepository< Customer> customerRepository; public CustomerService（ICustomerService rep） { customerRepository = rep; } public Customer IQueryable< Customer> GetCustomerByFilter（Expression< Func< Customer，bool>> where ）; { var customer = customerRepository.Get（Where））; if （customer == null ） 返回 null ; 返回客户; } } 存储库类如下： public interface IRepository< T> ：IDisposable 其中 T： class { T Get（Expression< Func< T，bool>>谓词）; } public class 存储库< T> ：IRepository< T> 其中 T： class { private ObjectContext上下文; private IObjectSet< T>对象集; public Repository（）： this （ new demonEntities（）） {} public 存储库（ObjectContext ctx） { context = ctx; objectSet = context.CreateObjectSet< T>（）; } public T Get（表达式< Func< T，bool>>谓词） { T entity = objectSet.Where< T>（谓词）.FirstOrDefault（）; if （entity == null ） 返回 null ; return objectSet.Where< T>（谓词）.FirstOrDefault（）; } i写了一个单元测试如下： [TestMethod（）] public void GetByFilter_ShouldReturn_ListofBroadSubjectArea_AfterAplyingFilters（） { var customer = new 客户（） { Id = 3 名称= Person1， StatusId = 1 }; var list = CreateList（）; var mockrepository = new Mock< ICustomerRepository>（）; mockrepository.Setup（p = > p.GetAll（））。返回（list.AsQueryable（））; var service = new CustomerService（mockrepository。对象）; var filter = service.GetCustomerByFilter（l = > l.Name .Trim（）。ToUpper（）== customer.Name.Trim（）。ToUpper（）&& l.Id！= customer.Id）。ToList（）; Assert.AreEqual（ 1 ，filter.Count（））; } 私人 静态列表<客户> CreateList（） { var list = new 列表< Customer>（） { new 客户{Id = 1 ，Name = Person1 StatusId = 1 }， }; 返回列表; } ohk !!我的函数应该检查客户到使用模拟创建的列表...但它不是...断言应该给出一个真（表明存在相同的记录）在这种情况下，但显然它不....请帮助我在这个解决方案 你好b $ b 我在过去的一小时里突然想到了它，终于找到了它。 :) 你只需要在你的web服务项目中创建一个default.aspx页面..！ 以下是应该解决您的疑问的链接... http://msdn.microsoft.com/en-us/library/ms243399（v = VS.90）的.aspx hello i was unit testing my service layer :I have a service layer named "CustomerService"public interface ICustomerService{ IQueryable<Customer> GetCustomerByFilter(Expression<Func<Customer, bool>> where);}public class CustomerService : ICustomerService{ private IRepository<Customer> customerRepository; public CustomerService(ICustomerService rep) { customerRepository = rep; } public Customer IQueryable<Customer> GetCustomerByFilter(Expression<Func<Customer, bool>> where); { var customer = customerRepository.Get(Where)); if (customer == null) return null; return customer; }}And the repository class is below:public interface IRepository<T> : IDisposable where T : class { T Get(Expression<Func<T, bool>> predicate); } public class Repository<T> : IRepository<T> where T : class { private ObjectContext context; private IObjectSet<T> objectSet; public Repository() : this(new demonEntities()) { } public Repository(ObjectContext ctx) { context = ctx; objectSet = context.CreateObjectSet<T>(); } public T Get(Expression<Func<T, bool>> predicate) { T entity = objectSet.Where<T>(predicate).FirstOrDefault(); if (entity == null) return null; return objectSet.Where<T>(predicate).FirstOrDefault(); }i wrote a unit test as follows: [TestMethod()] public void GetByFilter_ShouldReturn_ListofBroadSubjectArea_AfterAplyingFilters() { var customer = new Customer() { Id = 3 Name = "Person1", StatusId = 1 }; var list = CreateList(); var mockrepository = new Mock<ICustomerRepository>(); mockrepository.Setup(p => p.GetAll()).Returns(list.AsQueryable()); var service = new CustomerService(mockrepository.Object); var filter = service.GetCustomerByFilter( l => l.Name.Trim().ToUpper() == customer.Name.Trim().ToUpper() && l.Id != customer.Id).ToList(); Assert.AreEqual(1,filter.Count()); } private static List<Customer> CreateList() { var list = new List<Customer>() { new Customer{Id = 1,Name ="Person1"StatusId=1}, }; return list;}ohk!! my function should check the "customer " to the list created using Mock...but its not...Assert should give a true(indicating that the same record exists) in this condition but apparently its not.... Please help me in this 解决方案 HiI was breaking my head over it for the past hour and finally found it. :)U just have to create a default.aspx page in your web service project..!following is the link that should solve your doubt...http://msdn.microsoft.com/en-us/library/ms243399(v=vs.90).aspx 这篇关于单元测试服务层的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
