$ rails g controller api/v1/tests

$ rails g controller api::v1::tests

Usage:
  rails generate controller NAME [action action] [options]

Options:
      [--skip-namespace], [--no-skip-namespace]              # Skip namespace (affects only isolated engines)
      [--skip-collision-check], [--no-skip-collision-check]  # Skip collision check
      [--skip-routes], [--no-skip-routes]                    # Don't add routes to config/routes.rb.
      [--helper], [--no-helper]                              # Indicates when to generate helper
                                                             # Default: true
  -e, [--template-engine=NAME]                               # Template engine to be invoked
                                                             # Default: erb
  -t, [--test-framework=NAME]                                # Test framework to be invoked
                                                             # Default: rspec

Rspec options:
  [--request-specs], [--no-request-specs]        # Generate request specs
                                                 # Default: true
  [--controller-specs], [--no-controller-specs]  # Generate controller specs
  [--view-specs], [--no-view-specs]              # Generate view specs
  [--routing-specs], [--no-routing-specs]        # Generate routing specs
  [--helper-specs], [--no-helper-specs]          # Indicates when to generate helper specs

Runtime options:
  -f, [--force]                    # Overwrite files that already exist
  -p, [--pretend], [--no-pretend]  # Run but do not make any changes
  -q, [--quiet], [--no-quiet]      # Suppress status output
  -s, [--skip], [--no-skip]        # Skip files that already exist

Description:
    Generates a new controller and its views. Pass the controller name, either
    CamelCased or under_scored, and a list of views as arguments.

    To create a controller within a module, specify the controller name as a
    path like 'parent_module/controller_name'.

    This generates a controller class in app/controllers and invokes helper,
    template engine, assets, and test framework generators.

Example:
    `bin/rails generate controller CreditCards open debit credit close`

    CreditCards controller with URLs like /credit_cards/debit.
        Controller: app/controllers/credit_cards_controller.rb
        Test:       test/controllers/credit_cards_controller_test.rb
        Views:      app/views/credit_cards/debit.html.erb [...]
        Helper:     app/helpers/credit_cards_helper.rb

      create  app/controllers/api/v1/tests_controller.rb
