Hello,
I’m recently looking on how to test .rate_limit in my application, but I don’t really know how to be able to change the cache_store for only the test I’m running, since setting the store for all the application on test may trigger error while doing my other tests.
I’ve done a small app to test, but still don’t know how to specify a cache_store for on test.
I found that the cache store is passed into a lambda when the controller class is loaded. So the only option I see is to override the methods of the used store. This works for me:
cache = ActiveSupport::Cache::MemoryStore.new
allow(Rails.cache).to receive(:increment, &cache.method(:increment))
This applies only for the current test example. It could affect other code using cache.increment but hopefully that’s not a problem.
