Know of a Linux or Windows editor / IDE with support for TDD for RoR?

I saw a demo of VisualStudio's support for TDD for C++ (or C#, I can't
recall which) this past weekend and was impressed. Anybody know of an
editor or IDE for Linux (Ubuntu specifically) or Windows that has
built-in support for TDD for either Ruby or Rails?

Rake comes with great support for unit testing with Test::Unit out of the box, you don’t need an IDE to hook it all up for you. You can define a Rake::TestTask and just run ‘rake test’. Rails does this automatically. RSpec comes with a similar Rake task that’s as easy to define.

If you really want your IDE to show you colors and stuff, I know RubyMine supports testing Rails applications and is cross-platform (written in Java).

Hi Adam,

Rake::TestTask and just run 'rake test'. Rails does this automatically.

I'm a long-time user and fan of Test::Unit but TDD with it requires
quite a bit of typing. What I saw demonstrated with VisualStudio was
very impressive though. It supported Red-Green-Refactor at level I'd
never seen before. Write the test, it knows you don't have the method
you're testing and auto-generates it. That sort of thing. It was a
very brief demo but what he showed was very impressive. I've never
been a big fan of IDEs for Rails development. I use the Ruby version
of NetBeans because it lets me use the same tool on Windows and Linux.
That and the debugger. But it's got nothing like what I saw last
weekend re: built-in TDD support. I'll check out RubyMine.

Thanks!

Perhaps you want Autotest? Again, no IDE necessary.

(But I think method autogeneration in this case would be dangerous.
Doesn't that mean you don't see the test fail?)

I know that RSpec and Cucumber support an HTML output format where you
can see the red and green nicely displayed in your browser. I hate
Test::Unit, so I haven't used it enough to be sure if it does the same
thing, but it might.

Er...so does any decent editor. KomodoEdit (my current favorite) exists
for Windows, Linux, and Mac OS; so does jEdit.

That and the debugger.

Does ruby-debug-ide actually work with NetBeans? It didn't when I tried
earlier this year.

Best,

Hi Marnen,

You do see the test fail. Then you 'tell' it to generate the method.
Again, it was a very brief demo. I may schedule a follow-up with the
guy to see more. The thing that was really impressive is that he
didn't switch from one tool to another. The degree of integration of
the test tool into the development tool was like nothing I'd ever seen
before. But then I don't spend much time reviewing editors / IDEs.
That's why I asked. And yes, NB supports ruby-debug-ide. Has for a
couple of years. You have to have the gems installed and that can be
a bit of a pain. I had to download the last, not the latest, version
and install locally.

Best regards,
Bill

That might be cool if it doesn't limit your choice of testing framework.
My guess would be that having something so integrated into the IDE
likely locks to into whatever test framework the IDE vendor decided to
use. But, if it's flexible enough to provide choice of framework then I
could see it maybe saving a few keystrokes. Not that big of a deal to me
though. I mean how hard is it really to type def my_method ... end. And
then likely have to move the generated method so that I keep my class
files organized as I like.

question."
