# Test::Unit loads a default test if the suite is empty, and the only
# purpose of that test is to fail. As having empty contexts is a common
# practice, we decided to overwrite TestSuite#empty? in order to
# allow them. Having a failure when no tests have been defined seems
# counter-intuitive.

# method setup now iterates on the setup blocks. Note that all setup
# blocks must be defined with the block syntax. Adding a setup instance
