Before you run the tests for the first time you need to load the test database with the empty structure:
RAILS_ENV=test rake db:setup
rspec
guard # execute specs interactively
This is useful command also in reseting the test DB to empty and clean state.
Run all the tests suites:
- run
rspec spec
In addition to running all the spec tests with rake spec you can also run a single file with for example rspec ./spec/helpers/locations_helper_spec.rb or even a single tests inside a file by pointing it with the line number: rspec ./spec/helpers/locations_helper_spec.rb:23 That makes it faster to test a single feature that you are changing. However, it's good practice to run the whole test set before sending your code for other people to use (or to develop on).
To speed up tests, you can use guard. It watches the file system and runs tests automatically when files change:
Run guard and start coding. Saving a file triggers the change.
