=head1 NAME

Perl::Critic::TestUtilitiesWithMinimalDependencies - Testing functions that only depend upon strict, warnings, and Exporter.

=head1 SYNOPSIS

  use Perl::Critic::TestUtilitiesWithMinimalDependencies qw{
      should_skip_author_tests
      get_author_test_skip_message
      get_skip_all_tests_tap
  };

  if ( should_skip_author_tests() ) {
      print get_skip_all_tests_tap(), get_author_test_skip_message(), "\n";
      exit 0;
  }


  use Test::More;

  if (should_skip_author_tests()) {
      plan skip_all => get_author_test_skip_message();
  }

=head1 DESCRIPTION

This module is used by Perl::Critic only for self-testing. It
differs from Perl::Critic::TestUtils in that it only depends upon
strict, warnings, and Exporter.  This is important for tests
that need to hide the presence of other modules before starting.

=head1 IMPORTABLE SUBROUTINES

=over

=item C< should_skip_author_tests() >

Answers whether author tests should run.


=item C< get_author_test_skip_message() >

Returns a string containing the message that should be emitted when a
test is skipped due to it being an author test when author tests are
not enabled.


=item C< get_skip_all_tests_tap() >

Returns a string representing the TAP (Test Anything Protocol) output
for skipping an entire file.  This is useful if you don't want to load
any Test::* modules.
