[Rubycocoa-talk] Unit Testing Objective-C classes with RubyCocoa

[Rod S. <rsc...@xm...>]

I'm trying to do some unit testing with RubyCocoa and am having some  
problems. I have a main program like so:

int main(int argc, const char *argv[])
{
	return RBApplicationMain("../../PackRat/source/tests/rb_testmain.rb",  
argc, argv);
}


rb_testmain.rb is:

require 'osx/cocoa'
require 'test/unit/ui/console/testrunner'

OSX.ns_import :Backpack

class TC_PackRatTests < Test::Unit::TestCase
   def setup
	@backpack = Backpack.alloc.initWithSitename_token_ssl('username', '',  
false);
   end

   def teardown
     # Write teardown code here.
   end

   def test1
     # Write first test here.
   end
end

if $0 == __FILE__ then
   Test::Unit::UI::Console::TestRunner.run(TC_PackRatTests)
end

When I run the program I get the following:

/Library/Frameworks/RubyCocoa.framework/Resources/ruby/osx/objc/ 
oc_import.rb:323:in `_ns_behavior_method_added': Cannot override  
Objective-C method 'chomp' with Ruby method #chomp, they should both  
have the same number of arguments. (expected arity 0, got -1)

	from /Users/rod/Development/Projects/infiniteNIL/Build/Debug/../../ 
PackRat/source/tests/rb_testmain.rb:9

If I uncomment the require 'osx/cocoa' then it works, except of course  
ns_import fails because it doesn't know the method. Anybody know why  
I'm getting this error?

Thanks,

Rod
