Hi everyone
I need to find out the value passed into an indexer.
My code (c#) that I need to test is as follows:
string cacheKey = GetCacheKey(cacheKeyRequest);
string cachedValue = myCache[cacheKey] as string;
So, I need to be able to identify the valle "cacheKey" passed into the
indexer.
I have attempted to achieve this using a Mock of the cache object:
var cache = MockRepository.GenerateMock<WebDataCache>();
The idea being that after the code was run, I would try:
var actualCacheKey = cache.GetArgumentsForCallsMadeOn(a =>
a["somevalue"], opt => opt.IgnoreArguments())[0][0].ToString();
This gives me a compilation error: Only assignment, call, increment,
decrement, and new object expressions can be used as a statement.
I saw one suggestion to make this a function in the following way:
var actualCacheKey = cache.GetArgumentsForCallsMadeOn(a =>
a["somevalue"] = null, opt => opt.IgnoreArguments())[0][0].ToString();
This now compiles,but throws a run-time InvalidOperationException: No
expectations were setup to be verified, ensure that the method call in
the action is a virtual (C#) / overridable (VB.Net) method call.
Any suggestions? [Am using RhinoMocks.3.6.1]
Many thanks in advance
Griff
