今天我想开始对一个小的 asp.net MVC 3 Web（测试）应用程序进行单元测试，以学习一些新东西。
但事情比我预想的还要糟糕……
我现在已经阅读了一些关于与实体框架相关的单元测试的线程，现在我首先想为我的实体框架相关类实现接口，以便我可以为我的单元测试实现一个内存中的“数据库”。
我的代码库来自ASP.NET MVC 教程。我读过MSDN，但在我的情况下它对我没有帮助。
我想向您展示我的代码。我正在使用带有存储库的工作单元模式：
工作单位：
public class SqlUnitOfWork : IUnitOfWork, IDisposable
{
private SqlContext context = new SqlContext();
private IGenericRepository<Message> messageRepository;
private IGenericRepository<Receipt> receiptRepository;
private IGenericRepository<Useraccount> useraccountRepository;
private bool disposed = false;
public IGenericRepository<Message> MessageRepository
{
get
{
if (this.messageRepository == null)
{
this.messageRepository = new SqlGenericRepository<Message>(context);
}
return messageRepository;
}
}
public IGenericRepository<Receipt> ReceiptRepository
{
get
{
if (this.receiptRepository == null)
{
this.receiptRepository = new SqlGenericRepository<Receipt>(context);
}
return receiptRepository;
}
}
public IGenericRepository<Useraccount> UseraccountRepository
{
get
{
if (this.useraccountRepository == null)
{
this.useraccountRepository = new SqlGenericRepository<Useraccount>(context);
}
return useraccountRepository;
}
}
public SqlUnitOfWork()
{
}
~SqlUnitOfWork()
{
}
public virtual void Dispose(bool disposing)
{
if (!this.disposed)
{
if (disposing)
{
context.Dispose();
}
}
this.disposed = true;
}
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
public void Save()
{
context.SaveChanges();
}
}
这个实现了我创建的接口。
我的 sql 通用存储库：
public class SqlGenericRepository<TEntity> : IGenericRepository<TEntity> where TEntity : class
{
internal SqlContext context;
internal DbSet<TEntity> dbSet;
public SqlGenericRepository(SqlContext context)
{
this.context = context;
this.dbSet = context.Set<TEntity>();
}
~SqlGenericRepository()
{
}
public virtual IEnumerable<TEntity> Get(Expression<Func<TEntity, bool>> filter = null,
Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null, string includeProperties = "")
{
IQueryable<TEntity> query = dbSet;
if (filter != null)
{
query = query.Where(filter);
}
foreach (var includeProperty in includeProperties.Split
(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries))
{
query = query.Include(includeProperty);
}
if (orderBy != null)
{
return orderBy(query).ToList();
}
else
{
return query.ToList();
}
}
public virtual TEntity GetByID(object id)
{
return dbSet.Find(id);
}
public virtual void Insert(TEntity entity)
{
dbSet.Add(entity);
}
public virtual void Delete(object id)
{
TEntity entityToDelete = dbSet.Find(id);
Delete(entityToDelete);
}
public virtual void Delete(TEntity entityToDelete)
{
if (context.Entry(entityToDelete).State == EntityState.Detached)
{
dbSet.Attach(entityToDelete);
}
dbSet.Remove(entityToDelete);
}
public virtual void Update(TEntity entityToUpdate)
{
dbSet.Attach(entityToUpdate);
context.Entry(entityToUpdate).State = EntityState.Modified;
}
}
它实现了我编写的接口：
public interface IGenericRepository<TEntity> where TEntity : class
{
IEnumerable<TEntity> Get(Expression<Func<TEntity, bool>> filter = null, Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null, string includeProperties = "");
TEntity GetByID(object id);
void Insert(TEntity entity);
void Delete(object id);
void Delete(TEntity entityToDelete);
void Update(TEntity entityToUpdate);
}
我现在想为我的单元测试实现一个“InMemoryGenericRepository”，然后是一个“InMemoryUnitOfWork”。那些“InMemoryGenericRepository”会是什么样子？
我想我会在存储所有数据的存储库中使用通用列表：
IEnumerable<TEntity> List { get; set; }
但是我怎样才能适应这种方法：
public virtual IEnumerable<TEntity> Get(Expression<Func<TEntity, bool>> filter = null, Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null, string includeProperties = "")
{
IQueryable<TEntity> query = dbSet;
if (filter != null)
{
query = query.Where(filter);
}
foreach (var includeProperty in includeProperties.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries))
{
query = query.Include(includeProperty);
}
if (orderBy != null)
{
return orderBy(query).ToList();
}
else
{
return query.ToList();
}
}
所以它适用于我的
IEnumerable<TEntity> List { get; set; }
我希望你能做到我的问题结束。
