How do you run rspec and cucumber on Heroku?

Tags:

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!

Running cucumber on Heroku staging app

Similarly:

$ heroku rake cucumber --remote staging

Results in:

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.
