This one is a short one but a good one. One really useful trick is to launch Rails console in test mode:
❯ RAILS_ENV=test rails c Running via Spring preloader in process 41705 Loading test environment (Rails 22.214.171.124) irb: warn: can't alias context from irb_context.
You can check the Rails environment this way:
2.7.0 :001 > Rails.env "test"
The benefit to this is that you can work directly with FactoryBot and experiment with factories:
2.7.0 :002 > project = FactoryBot.create(:project, name: "Scott's Project")
FactoryBot is installed via Gemfile and locked into test environment only (which is why you need to launch Rails console in test mode):
group :test do # Adds support for Capybara system testing and selenium driver gem "capybara", ">= 2.15" gem "selenium-webdriver" # Easy installation and use of web drivers to run system tests with browsers gem "webdrivers" gem 'factory_bot_rails' #gem 'database_cleaner' # gem 'shoulda' # gem 'shoulda-matchers' end
