Service Testing with Request

Mac · April 14, 2016, 2:18pm

I was wondering if there is a recommended way to test service methods that utilise the Request and cache object.

public object Any(MyDto request){
   return Request.ToOptimizedResultUsingCache(Cache, ...);
}

I have test doubles, xunit AppHostFixtures and a few other approaches but was wondering if there was a recommended or cleaner way to test cache service methods isolated from the AppHost?

I’d just be using a self-host integration test, it’s easier to setup and it tests what actually happens.

Otherwise you could potentially use the generic BasicAppHost and inject a dummy BasicRequest() into your Service then read what was written to the req.Response.OutputStream.

Well for what it’s worth, here is what I’m using

ServiceStackCacheServiceTesting.cs

namespace ServiceStackCacheServiceTesting
{
    using System;

    using ServiceStack;
    using ServiceStack.Caching;
    using ServiceStack.Testing;
    using ServiceStack.Web;

    using Xunit;

Yep Mocking is fine, although my preference is to test as much as I can, with the least code required so I’d always use Integration Tests for anything testing functionality in the Request Pipeline.
