Rails - Mar 2007 - 'rake test' abends with just Test failures - real error thrown away

Railsters:

The Rails test engine contains otherwise flawless error handling. So, after 
being bedeviled by intermittent "Test failure" abnormal test
terminations, I
finally got around to --trace-ing the problem, and when I found it the 
clumsiness surprised me:

desc ''Test all units and functionals''
task :test do
  Rake::Task["test:units"].invoke       rescue got_error = true
  Rake::Task["test:functionals"].invoke rescue got_error = true

  if File.exist?("test/integration")
    Rake::Task["test:integration"].invoke rescue got_error = true
  end

  raise "Test failures" if got_error
end

What that means is, if any test_ case fails, we see a healthy error message, 
but if the test rig itself fails, ''rescue got_error = true''
will throw away
the e.message and e.backtrace, and the raise "Test failures" will
provide an
irrelevant error message and backtrace.

I''m going to copy this task :test into my lib/tasks/project.rake file,
and
replace the error hiding with a real error handling block. Further, if the 
test rig itself has failed, I don''t care to keep running any more
tests, so
I won''t bother with the system that tolerates their faults.

Why was this method so clumsy, and hasn''t anyone asked for an upgrade
on it
yet?

Thanks!

And to think that just this morning I ran ''gem install -v=1.2.2 
rails --include-dependencies'', just to sync all my versions on all my 
computers... ;-)
