Hi all,
I was running some tests in Ruby and I noticed that the snippet of code below is considered as 2 assertions :
def test_assert_match
assert_match /world/, 'hello world'
end
How come ?
Thanks a lot!

uses two calls to assert: one to check that the given matcher (regepx) responds to =~
, and one to check that the matcher and the string do match.
def assert_match matcher, obj, msg = nil
msg = message(msg) { "Expected #{mu_pp matcher} to match #{mu_pp obj}" }
assert_respond_to matcher, :"=~"
matcher = Regexp.new Regexp.escape matcher if String === matcher
assert matcher =~ obj, msg
end
