Unit Of Work & Generic Repository with Entity Framework 5

Question

I\'m using ASP.NET MVC 4 with Entity Framework 5. I have model classes and Entity Maps to map existing tables to those model classes. All this is setup fine and works great.

Answer 1

Your ExampleService class is expecting IUnitOfWork, that means you just need another IUnitOfWork that is a Mock and its GetRepository() method will return an IRepository Mock.

For example (not really a Mock but In-Memory stub):

  public InMemoryRepository<T> : IRepository<T> where T : class
  {
        ........
  }

  public InMemoryUnitOfWork : IUnitOfWork
  {
       public IRepository<TEntity> GetRepository<TEntity>() where TEntity : class
       {
            return new InMemoryRepository<TEntity>();
       }
  }

Then:

public IEnumerable<Example> GetAll()
{
    // Create Unit Of Work object
    IUnitOfWork uow = new InMemoryUnitOfWork();

    // Create Service with Unit Of Work
    ExampleService service = new ExampleService(uow);

    return service.getAll();
}
