Rails test a single directory or section
added on :: 21 June 2014
To test a single directory rather than the entire test suite. e.g to test your beautiful "test/models" directory say:
If you want to test a single file
rake test TEST=test/integration/pages_test.rb
If you cannot be bothered to type "bundle exec rake test" or "test" all the time, best to keep a little snipet in your beloved bash_profile (Users/ypurnicename/.bash_profile) file"
alias t='bundle exec rake test'
Then you can just type 't' to run the entire test suite and be happy.
As for test log or have a shortcut for it;
alias ttl=' tail -f log/test.log'
To test a directory ie:controllers
