Update: You can specify a line number to run in your spec if you’re wanting to run a specific spec. Example: rspec spec/controllers/sessions_controller_spec.rb:90

Tired of looking this up and want to use my writing part of my brain to blog it:

1
2

rake spec SPEC=spec/controllers/sessions_controller_spec.rb \
  SPEC_OPTS="-e \"should log in with cookie\""

This is importatnt to me while coding Rails because if I just run

1

rspec specs/controllers/sessions_controller_spec.rb

the test database isn’t cleared out. By running rake spec I get that.
