Docker for Rails Developers

Our First Test

Having installed RSpec in our project, it’s not very satisfying to see zero tests running. Let’s rectify that right now by creating our first test, so that we can see some actual test code running.

Let’s generate a spec for our User model:

$ docker-compose exec web bin/rails generate rspec:model user
      create  spec/models/user_spec.rb

Linux Users: File Ownership
	Remember to chown the files we’ve generated so you can edit them (see ​File Ownership and Permissions​): $ sudo chown <your_user>:<your_group> -R .

Open the newly created spec/models/user_spec.rb file in your editor. ...
