# Test::Unit loads a default test if the suite is empty, whose purpose is to
# fail. Since 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.

# Contest adds +teardown+, +test+ and +context+ as class methods, and the

# blocks. Note that all setup and teardown blocks must be defined with the

# of this library.
