Rails - Rake test and rubocop in one task

Question

I'm trying to setup my rails project so that all the verification required by a contributor is in one command, currently we have been running:

rake test

But now we also want to use rubocop for static analysis:

rubocop -R -a

I want this to be executable in one simple rake task. It would be nice to override 'rake test' to run rubocop then the standard rake test stuff for a rails project, as then no-one will have to remember to change the command. But if I have to create a separate rake task, that's probably fine too.

I've seen the rubocop rake integration here, at the bottom, but I'm not sure how to bundle that with 'rake test' into one task... Any thoughts?

Answer 1

You could easily define your own rake task which first invokes Rails' test rake task and then the code snippet you mentioned for rubocop.

For example, in a .rake file you could have something like that:

require 'rubocop/rake_task'

desc 'Run tests and rubocop'
task :my_test do
  Rake::Task['test'].invoke
  RuboCop::RakeTask.new  
end

If you feel the need to customize the call to Rubocop and that involves more code, you could create another custom task, say :rubocop, which you then invoke from :my_test as well.

Finally, an alternative to creating your own rake task and sticking with rake test would be to modify your test_helper to invoke whatever you need invoked after testing is completed.
