Installing Cypress

Setting up Cypress involves two different steps. First we need to install Cypress itself. Then, we need to install the Cypress-Rails gem to help us integrate Cypress into our system.

First, install Cypress as a package:

$ yarn add --dev cypress

Now we need to add two gems: the Cypress-Rails gem and the dotenv gem. The gems both go in the Gemfile in the development and test groups:

group :development, :test do
	# <existing gems...>
	gem "cypress-rails"
	gem "dotenv-rails"
end
