单元测试服务层 [英] unit testing service layer

问题描述

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 = < span class =code-digit> 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...

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

Hi
I 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...
