There are a lot of rake tests failing in a ruby on rails project [1], all with same error (can't convert nil into String), and I don't have any idea why is this happening neither how I should debug it.

For example, this is the first tracebak of rake test (I have attached full rake test traceback at the end of the message [2]).

Error:

And I have more than 200 test with errors of a total of 1448 tests.

The question is, from where must I start to debug it? Why I'm getting same error in +90% of tests?

In case of debugging. I reccomend to use gem 'pry-rails'. Just bundle this gem and add 'binding.pry' to failing test. It will open console with all variables from your test, so you can manually check it. I hope it helps you to find out what's wrong.

It's might be one of the problems of Cucumber version.

You can fix this by upgrading cucumber-rails to a recent version. Just edit your Gemfile to show this:

gem 'cucumber-rails', '>= 1.1.1' or newer version

its solved my error when i got the same.

In your case, its pointed delayed_job gem

If you are using bundler try prefixing the script or rake task with "bundle exec" e.g.

bundle exec script/delayed_job -n 2 start

and Try!!!!

  • Even if I actually don't have cucumber-rails gem installed? https://github.com/gamersmafia/gamersmafia/blob/master/Gemfile – Draco Mar 28 '13 at 12:28
  • @Draco Check the updated answer and give a try... and let know – Sri Mar 28 '13 at 12:35
  • Ok, I did it, you can check this text file: https://dl.dropbox.com/u/42306424/try1_stackoverflow.txt So that means all my problems are caused due to an error with "ip_bans"? – Draco Mar 28 '13 at 12:49
  • What version of bundler you using? – Sri Mar 28 '13 at 12:55
  • Change that `'"ip_bans"'` to `'ip_bans'` and try – Sri Mar 28 '13 at 12:57
  • Mmm... incredible, I can't find it. I tried (with git grep "ip_bans" and grep -Rli 'ip_bans' ./ ) but I can't even find "a.attrelid" for example :/ – Draco Mar 28 '13 at 20:44
  • PD: How can I undo what "bundle exec script/delayed_job -n 2 start " did? – Draco Mar 28 '13 at 20:45
