As far as doing UI testing with watir/firewatir goes, NetBeans is a fantastic IDE. It’s lightweight, but powerful enough to do pretty much anything I need. The integration with Test::Unit is particularly good: I select a test file, I call “Run > Test File”, I wait, I see pretty green and red indicators for the tests. But what if I want to run the tests from the command line? The NetBeans project structure means that it isn’t a matter of simply running ruby all_my_tests.rb. I took a look at what NetBeans actually did when it runs the test files (using the magic of ps -ax), and I’ve managed to compress the whole thing into:

cd project_dir
ruby -I lib -I test test/all_my_tests.rb

That’s the mac/unix/linux syntax. The windows syntax is the same:

cd project_dir
ruby -I lib -I test test\all_my_tests.rb
