Why does this regular expression match?


Using Test::Unit:

r1 = /a*/
assert_nil,‘A’ =~ r1

The error I get implies that it would match in the same way that the
following would match
‘a’ =~ r1

Can anyone offer any suggestions?


ps. done a google search on Test::Unit lately?


The asterisk means “Zero or more of these”. You may want to use /a+/
(One or more 'a’s).
