Change Mini Test by Rspec + FactoryBot + Dummy App

[andresgutgon]

What?

While doing a couple of PR in this repo I notice specs data is shared for all specs. This makes harder to add new test cases. Also this gem relay on ActiveRecord. What if specs were done again a dummy rails app with Rspec and FactoryBoy.

This is an example

The new elements

1. Rspec: I've work with Rspec and I find super clear their DSL. But this is just my opinion. Nothing again Mini Test.
2. FactoryBot: It makes super easy to generate isolated test data for each spec. I find it super helpful. Also seed.rb file is getting big.

What do you think? What are your thoughts on this?
