Help Req. in Mocking the Cache using RhinoMocks

In my project we are using Rhino mocks for the automated unit testing. In that we are not able to mock the HttpContext.Current.Cache
Please let me know if we can mock the cache for the unit testing using Rhinomocks

 SOLUTION 1:

As per my information, to mock the HttpContext objects in Rhino Mocks, we have to stub the HttpContext.

PSB:

System under test:

01 public class MyContext
02	{

 

03	private readonly HttpContextBase _context;
04	// This constructor is called by production system.

 

05	public MyContext() : this(new HttpContextWrapper(HttpContext.Current))
06	{}

 

07	// Test calls this constructor
08	public MyContext(HttpContextBase context)

 

09	{
10	_context = context;

 

11	}
12	public bool IsItemCached(string item)

 

13	{
14	return _context.Cache[item] != null;

 

15	}
16	}

Unit tests:

01	[TestFixture]
02	public class MyContextTester

 

03	{
04	private HttpContextBase _contextStub;

 

05	private MyContext _myContext;
06	[SetUp]

 

07	public void StartTest()
08	{

 

09	_contextStub = MockRepository.GenerateMock<HttpContextBase>();
10	_myContext = new MyContext(_contextStub);

 

11	}
12	[Test]

 

13	public void IsItemCached_if_Cache_item_is_null_return_false()
14	{

 

15	_contextStub.Stub(x => x.Cache).Return(HttpRuntime.Cache);
16	Assert.IsFalse(_myContext.IsItemCached("NotThere"), "False is expected.");

 

17	}
18	[Test]

 

19	public void IsItemCached_if_Cache_item_is_NOT_null_return_true()
20	{

 

21	HttpRuntime.Cache.Insert("I am HERE", "value");
22	_contextStub.Stub(x => x.Cache).Return(HttpRuntime.Cache);

 

23	Assert.IsTrue(_myContext.IsItemCached("I am HERE"), "True is expected.");
24	}

}
