I’ve noticed that if you install certain testing gems, like Factory Girl, or Rspec, that your Rails application will create test files for these libraries instead of using the defaults. Even further you can configure the generators used by your Rails app in /config/application.rb
# Configure generators values. Many other options are available, be sure to check the documentation. # http://edgeguides.rubyonrails.org/generators.html#customizing-your-workflow config.generators do |g| g.stylesheets false g.test_framework :rspec g.fallbacks[:rspec] = :test_unit g.fixture_replacement :factory_girl end
I’ve been anxious however in deciding which testing tools to learn and use with my project. If I choose the wrong one, then all the scaffold generated test code will be generated for the test framework I might choose to quit using at some point.
This is not completely correct though, as I’ve discovered.
I found that the following commands will generate the empty spec files.
rails generate rspec:model rails generate rspec:view rails generate rspec:controller
Even better though, if you’re looking for scaffold style files to be put in place, use the following syntax to generate scaffold code.
rails generate rspec:scaffold Post title:string body:text
If you decide to use basic Test::Unit based tests, instead of going with Rspec, you can also reconfigure your app to use Test::Unit again with generators, and then use the rake commands to generate the files that were generated via rspec.
