running single rails unit/functional test

Question

As title.

ruby test/functionals/whatevertest.rb doesn't work, that requires me to replace all require 'test_helper' to require File.dirname(__FILE__) + '/../test_helper'. For some reason most of those test templates have such issue, so I rather to see if there is a hack I could get around it.

Answer 1

On Linux? why not try (cd test && ruby functionals/whatevertest.rb). Note, the parentheses are important as otherwise your current directory will change to the subdirectory. What it does is fork another shell, change to the subdirectory in it, and run the test.

Answer 2

Try this:

ruby -Ilib:test test/functionals/whatevertest.rb

Answer 3

The answer for the title question would be:

ruby unit/post_test.rb -n selected_test # use to run only one selected test

but for the body of the question tvanfosson gave a good answer.
