Question

我实现了一个UnitOfWork和Repository模式，如here所述，其中UnitOfWork包含对每个存储库的引用。我正在为我的项目添加单元测试，我想创建一个存根UnitOfWork。问题是我似乎无法让Rhino Mocks创建一个存根UnitOfWork，它会抛出异常。我认为原因是因为它试图获取数据库的连接字符串。有谁知道我做错了什么？

单元测试

[Test]
public void About_page_should_render()
{
    var unit = MockRepository.GenerateStub<UnitOfWork>(); //Throws exception
    var controller = new HomeController(unit);

    var result = controller.About() as ViewResult;

    Assert.NotNull(result);
}

工作单位结构

public class UnitOfWork
{
    private SampleRepository _sampleRepository;

    public SampleRepository SampleRepository 
    {
        get
        {
            if (this._sampleRepository == null)
                this._sampleRepository = new SampleRepository(context);

            return this._sampleRepository;
        }
    }
}

抛出空指针的方法

private static DbConnection GetConnection()
{
    return new SqlConnection(ConfigurationManager.ConnectionStrings[CON_STRING].ConnectionString);
}

堆栈跟踪
