A Window Into Functional Tests

So like any ruby blooded human, I create functional tests for my rails applications. However, things don’t always go as planned; a redirect instead of a success, but where to?, the assigns is right, but the flash was wrong, etc.

Sometimes you just need a way to peek at what you get back. If you enjoy gouging your eyes out you can do a puts @response or @response.body

A slightly better alternative is to spit the body to a file and preview it in firefox.

    tmpfile = File.new(tmpname = 'tmp/test_page.html', "w")
    tmpfile.puts @response.body
    tmpfile.close
    `firefox #{tmpname}`

Put this after any get, post, etc, and you will get a decent html output of your view (sans stylesheets and valid links) Although nothing is stopping you from outputting to public, running script/server, and viewing it from there.

  • If your dealing with redirects, don’t forget about follow_redirect!
  • If your crossing controllers, use integration tests =)

It’s not the be all end all of solutions, but it helps for a quick glimpse while fixing tests.
Hope it helps!
