我正在使用ServiceStack / StructureMap / Moq。 服务调用Session,它的类型为ServiceStack.CacheAccess.ISession。 在单元测试中,我使用Moq创建了一个Mock对象,并将其添加到StructureMap配置中:
protected Mock<ISession> sessionMock = new Mock<ISession>();
ObjectFactory.Configure(
cfg =>
{
cfg.For<ISession>().Use(sessionMock.Object);
然而,当Session对象为空时我并不感到惊讶 -- 我相信我肯定漏掉了某一步。那么我需要做什么才能用模拟对象填充我的Session属性呢?
[编辑] 这里是一个简单的测试场景
要进行测试的代码。简单的请求/服务
[Route("getKey/{key}")]
public class MyRequest:IReturn<string>
{
public string Key { get; set; }
}
public class MyService:Service
{
public string Get(MyRequest request)
{
return (string) Session[request.Key];
}
}
基本测试类和MockSession类
// test base class
public abstract class MyTestBase : TestBase
{
protected IRestClient Client { get; set; }
protected override void Configure(Container container)
{
// this code is never reached under any of my scenarios below
container.Adapter = new StructureMapContainerAdapter();
ObjectFactory.Initialize(
cfg =>
{
cfg.For<ISession>().Singleton().Use<MockSession>();
});
}
}
public class MockSession : ISession
{
private Dictionary<string, object> m_SessionStorage = new Dictionary<string, object>();
public void Set<T>(string key, T value)
{
m_SessionStorage[key] = value;
}
public T Get<T>(string key)
{
return (T)m_SessionStorage[key];
}
public object this[string key]
{
get { return m_SessionStorage[key]; }
set { m_SessionStorage[key] = value; }
}
}
还有测试。请参见评论,了解我看到失败的地方。我并没有真正期望版本1和2能够工作,但希望版本3能够。
