I’ve been reading the Learn app from thoughtbot code and I notice that in most specs the spec_helper is added to it; why is this necessary if in most cases the spec just need something that act as it’s the class under test. Looking at the specs for app/services and app/decorators in here.
It’s seems to me that not adding spec_helper for all the specs that doesn’t need it it will improve dramatically the speed of the test.
Can somebody explain to me this decision? Of course it should be somebody from thoughtbot
