Installazione Rspec

Dopo aver eseguito il passaggio precedente ed aver installato le gemme per la suite di test inizializzare rspec con il comando sottostante

rspec --init

Apri il file .rspec e sovrascrivi il contenuto con

.rspec

--require rails_helper
--format documentation
--order random
--color

Apri il file spec/spec_helper.rb e sovrascrivi il contenuto con

spec/spec_helper.rb

Apri il file spec/rails_helper.rb e sovrascrivi il contenuto con

Aggiungere, in config/initializers/generators.rb queste configurazioni per bloccare la generazione automatica dei test da parte di Rails.

config.generators do |g|
  g.test_framework :rspec,
                   fixtures:         true,
                   view_specs:       false,
                   helper_specs:     false,
                   routing_specs:    false,
                   controller_specs: false,
                   request_specs:    false
end
