Yes (Unsafe)

2.14

-

Identifies redundant spec type.

After setting up rspec-rails, you will have enabled config.infer_spec_type_from_file_location! by default in spec/rails_helper.rb. This cop works in conjunction with this config. If you disable this config, disable this cop as well.

Safety

This cop is marked as unsafe because config.infer_spec_type_from_file_location! may not be enabled.

Examples

# bad
# spec/models/user_spec.rb
RSpec.describe User, type: :model do
end

# good
# spec/models/user_spec.rb
RSpec.describe User do
end

# good
# spec/models/user_spec.rb
RSpec.describe User, type: :common do
end
