To verify if the variable $str contains the word “test” you would use

CORRECT ANSWER : if ($str = ~/test/)

Discussion Board
String variable

Your "CORRECT ANSWER" yields true for all strings $str

{ my $str = '''' ; if ($str = ~/test/) { $ret = "true"; } else { $ret = ''false''; }; print "[$ret]\n"; }
{ my $str = ''test''; if ($str = ~/test/) { $ret = "true"; } else { $ret = ''false''; }; print "[$ret]\n"; }

I would normally write
if ($str =~ /test/)
