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

is a Proc
by checking whether it responds to call
, cf.:

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.
