r = MockRedis.new(:some, :cool => :options). now pretend r is a redis client. see github.com/ezmobius/redis-rb. DO NOT USE IN PRODUCTION. PLZ. KTHX. This was based on a random file in assaf's "vanity", but as I extended it, it seemed like it needed its own repo.

QUESTION
I stumbled across a curious behaviour and haven't been able to figure out what I was doing wrong. I hope somebody can enlighten me.
I was trying to stub the Redis client during my tests in a Rails application. Therefore I was using the MockRedis gem. I have created a RedisFactory
class with the single class method .create
, which I wanted to stub with an optional MockRedis
instance like so:

is a Proc
by checking whether it responds to call
, cf.:
- https://apidock.com/ruby/Proc/call
- https://github.com/seattlerb/minitest/blob/b84b8176930bacb4d70d6bef476b1ea0f7c94977/lib/minitest/mock.rb#L226
Unfortunately, in this specific case Redis
as well as the passed MockRedis
-instance both provide a generic call
-method for executing Redis commands, cf.:
You already found the correct workaround. In this case, your only chance is to explicitly use the proc-version of stub
.
Note: There are some communities using def call
as a pattern with ServiceObjects in Ruby which may have a difficult time using minitest's stub
. It is probably a good idea to open an issue in seattlerb/minitest.
