How do you run rspec and cucumber on Heroku?
I'd like to be able to run rspec and cucumber on my staging app on Heroku. I have a separate production app and I push my development branch to staging and my master branch to production.
I have set the RACK_ENV variable to 'staging' and have also added a staging.rb config file.
Running rspec and cucumber locally:
Both rspec and cucumber run fine locally using the commands
$ rspec spec
..
$ cucumber features
Running rspec on Heroku staging app
The problem is that I can't get them to run on my Heroku staging app. I understand that the correct way to rspec on Heroku is:
$ heroku rake spec --remote staging
Whenever I run this though I get the following errors:
rake aborted!
You have a nil object when you didn't expect it!

Similarly:

The issue is clearly something to do with the database but I'm not sure how to address it.

The problem is that testing uses a separate database, not the one on which the application is running. This second database you don't get on Heroku. See Running Rails unit tests on Heroku for the answer to a similar question.
