Since you are using Ruby 1.9.3, the line
require 'test/unit'
Will require the Minitest gem. In contrast, in Ruby 1.8.7, this would
include the Test::Unit gem.
If you do a rescue without a type specified, the default type is
StandardError, which is a subclass of Exception.
In Minitest, when an assertion fails, a MiniTest::Assertion is thrown. This
is a subclass of Exception rather than StandardError. Hence it will not be
caught by the rescue.
You need to add the exception type:
require 'test/unit'
class TC_Sample < Test::Unit::TestCase
def test_01
begin
assert(false)
rescue MiniTest::Assertion
p "Batdog to the Rescue!"
end
end
end
