单元测试方法:GetUserInfo
以下是包含方法的类:
public class AccountService : IAccountService
{
IUnitOfWork _UnitOfWork;
public AccountService(IUnitOfWork unitOfWork)
{
_UnitOfWork = unitOfWork;
}
public UserInfo GetUserInfo(string userName, string password)
{
var userInfo = new UserInfo();
userInfo.UserType = UserType.Invalid;
// Statement of interest
var portalUser = _UnitOfWork.Repository<DvaPortalUser>().Query().Filter(t => t.Email == userName && t.Password == password).Get().FirstOrDefault();
//....Rest of the code is not included for clarity
}
}
模拟IUnitOfWork的界面:
public interface IUnitOfWork
{
void Dispose();
void Save();
void Dispose(bool disposing);
IRepository<T> Repository<T>() where T : class;
}
存储库实施:
public class Repository<TEntity> : IRepository<TEntity> where TEntity : class
{
public virtual RepositoryQuery<TEntity> Query()
{
var repositoryGetFluentHelper = new RepositoryQuery<TEntity>(this);
return repositoryGetFluentHelper;
}
internal IEnumerable<TEntity> Get(
Expression<Func<TEntity, bool>> filter = null,
Func<IQueryable<TEntity>,
IOrderedQueryable<TEntity>> orderBy = null,
List<Expression<Func<TEntity, object>>>
includeProperties = null,
int? page = null,
int? pageSize = null)
{
IQueryable<TEntity> query = DbSet;
if (includeProperties != null)
includeProperties.ForEach(i => query.Include(i));
if (filter != null)
query = query.Where(filter);
if (orderBy != null)
query = orderBy(query);
if (page != null && pageSize != null)
query = query
.Skip((page.Value - 1)*pageSize.Value)
.Take(pageSize.Value);
return query.ToList();
}
}
RepositoryQuery实现:
public sealed class RepositoryQuery<TEntity> where TEntity : class
{
private readonly List<Expression<Func<TEntity, object>>> _includeProperties;
private readonly Repository<TEntity> _repository;
private Expression<Func<TEntity, bool>> _filter;
private Func<IQueryable<TEntity>,
IOrderedQueryable<TEntity>> _orderByQuerable;
private int? _page;
private int? _pageSize;
public RepositoryQuery(Repository<TEntity> repository)
{
_repository = repository;
_includeProperties = new List<Expression<Func<TEntity, object>>>();
}
public RepositoryQuery<TEntity> Filter(Expression<Func<TEntity, bool>> filter)
{
_filter = filter;
return this;
}
public IEnumerable<TEntity> Get()
{
return _repository.Get(
_filter,
_orderByQuerable, _includeProperties, _page, _pageSize);
}
}
单元测试方法:
[TestMethod]
public void AccountService_GetUserInfo_SuccessfulLogin()
{
var _UnitOfWork = new Mock<IUnitOfWork>();
_AccountService = new AccountService(_UnitOfWork.Object);
_UnitOfWork.Setup(a => a.Repository<T>())).Returns(??); //How do I setup this statement?
_UnitOfWork.VerifyAll();
}
问题:如何为语句_UnitOfWork.Repository()?
设置模拟调用答案 0 :(得分:1)
我不知道你的IRepository<T>
是如何实现的,但我猜你的Query
方法会返回IEnumerable<T>
或列表。
internal interface IRepository<T>
{
IEnumerable<T> Query();
}
// your mock
_UnitOfWork.Setup(a => a.Repository<DvaPortalUser>())).Returns(() => new MyTestRepository());
定义您的存储库的显式实现。
// your implementation
public class MyTestRepository : IRepository<DvaPortalUser>
{
public IEnumerable<DvaPortalUser> Query()
{
// return some test users (mocks)
return new List<DvaPortalUser> {new DvaPortalUser(), new DvaPortalUser()};
}
}
定义模拟而不是实现
var repository = new Mock<IRepository<DvaPortalUser>>();
// return some test users (mocks)
repository.Setup(a => a.Query()).Returns(new[] { new DvaPortalUser() });
_UnitOfWork.Setup(a => a.Repository<DvaPortalUser>()).Returns(repository.Object);
您的选择取决于您的解决方案。
