I have a Rakefile that I am using to create and upload a gem.  
However, I am having a problem with Rake::TestTask not aborting the  
make when of the unit tests fails.

I’m basically doing:

spec = Gem::Specification.new do |spec|  
#…etc…  
end

Rake::GemPackageTask.new(spec)

Rake::TestTask.new do |t|  
t.libs \<\< ‘test’  
t.test\_files = FileList[‘test/\*.rb’]  
t.verbose = true  
t.warning = true  
end

task ‘upload-gem’ =\> [‘test’, ‘gem’] do  
end

task :default =\> [‘upload-gem’]  
end

How do I make my unit tests abort the gem creation?
