NAME

Test::XML::Twig - Test XML::Twig handlers

SYNOPSIS

  use Test::XML::Twig tests => 2;
  use My::Twig qw( handler );
  test_twig_handler(
      \&handler,
      '<foo/>', '<bar/>',
      'turns foo to bar',
  );
  test_twig_handlers(
      { twig_handlers => { 'foo' => \&handler } },
      '<foo/>', '<bar/>',
      'turns foo into bar',
  );

DESCRIPTION

This module is for testing XML::Twig handlers.

FUNCTIONS

All functions are exported.

get_twig ( INPUT [, ARGS ] )

Return a parsed twig of INPUT, or undef on parse failure. Optionally, ARGS may be supplied as a set of hash-like parameters to be passed into the twig constructor.

test_twig_handler ( HANDLER, INPUT, EXPECTED, TESTNAME [, COND ] )

Parse INPUT, using HANDLER as a twig_handler (i.e: it gets called after the parse tree has been built). Tests that the result is the same as EXPECTED (which can be either a string of XML or a quoted regex). HANDLER must be a code ref.

Optionally, COND can be supplied. Instead of the handler being called with the root element of INPUT, COND will be used with first_child() to select an alternative element.

Returns true / false depending upon test success.

test_twig_handlers ( ARGS, INPUT, EXPECTED, TESTNAME )

This is similar to test_twig_handler(), but with more flexibility. The first argument, ARGS, is a hash reference which can be used to specify any of the ordinary parameters to twig's constructor. This lets you test things like start_tag_handlers, as well as multiple twig_handlers together.
