doing 'man test' yields the following:
Code:
          condition1 -a condition2
                True if both condition1 and condition2 are  true.
                The -a binary primary is left associative and has
                higher precedence than the -o binary primary.

          condition1 -o condition2
                True if either condition1 or condition2 is  true.
                The -o binary primary is left associative.

perl::critic::policy::controlstructures::prohibitcascadingifelse

Perl::Critic::Policy::ControlStructures::ProhibitCascadiUserEContributed Perl DPerl::Critic::Policy::ControlStructures::ProhibitCascadingIfElse(3)

NAME

       Perl::Critic::Policy::ControlStructures::ProhibitCascadingIfElse - Don't write long "if-elsif-elsif-elsif-elsif...else" chains.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Long "if-elsif" chains are hard to digest, especially if they are longer than a single page or screen.  If testing for equality, use a hash
       lookup instead.	If you're using perl 5.10 or later, use "given"/"when".

	   if ($condition1) {	      #ok
	       $foo = 1;
	   }
	   elsif ($condition2) {      #ok
	       $foo = 2;
	   }
	   elsif ($condition3) {      #ok
	       $foo = 3;
	   }
	   elsif ($condition4) {      #too many!
	       $foo = 4;
	   }
	   else {		      #ok
	       $foo = $default;
	   }

CONFIGURATION

       This policy can be configured with a maximum number of "elsif" alternatives to allow.  The default is 2.  This can be specified via a
       "max_elsif" item in the .perlcriticrc file:

	   [ControlStructures::ProhibitCascadingIfElse]
	   max_elsif = 3
