Unit testing code that depends on IFusionCache

[runegri]

Hi. I am trying to write unit tests for some classes that reference an IFusionCache object. Are there any recommendations on how I can setup a mock object so that I can simulate the various scenarios where data is found in the cache or not found in the cache? I could probably setup a full FusionCache instance for each test, but that seems very counter productive and error prone.

Ideally I would love to setup various mocks, where one has the expected data, one does not have the expected data and fusion cache calls my factory method, and so on.

Hi @runegri sorry for the delay, have you been able to do it?
I know of multiple people in the community that are using mockinng with FusionCache, and I think it's working fine: have you found any particular issue you can share?
Thanks!

No we decided to instead use a minimally configured FusionCache that only runs against a local memory cache. This was easier since it is difficult to predict the exact behaviour of FusionCache in a mock.

It turns out that the following setup was fast enough for our tests:
var fusionCache = new FusionCache(new OptionsWrapper<FusionCacheOptions>(new FusionCacheOptions()));

Got it, thanks for the update! Glad you solved it.
