rake test vs rake test RAILS_ENV=test

Is it bad to invoke 'rake test' with RAILS_ENV=test? I get significantly different results when I do or don't. When I don't include a RAILS_ENV, the migration check is done against my development profile, but the tests seem to execute against the test profile. When I set RAILS_ENV to test, the migration check is performed on the test profile, but only my functional tests are run (succesully) and then then it errors out with what looks like an empty call to the test loader.

C:/opt/ruby/186/bin/ruby.exe -I"lib;test" "C:/opt/ruby/186/lib/ruby/ gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" Errors running test:units!

Am I doing something wrong?

Hi Nathan Beyer

   I did not see any error.But why are you doing like this.No need to specify RAILS_ENV=test The explanation is If execute from konsole

rake #This run all tests rake test:units #Run all unit tests only rake test:functionals #Run only functional tests
