However if the output is complex and changes from version to version, maintenance of the expected output could be costly. This module allows one to use the test code to generate the expected output, so that if the differences with model output are expected, one can easily refresh the model output. =head1 EXPORT ok_regression =cut use Test::Builder::Module; use Test::Differences; use base qw(Test::Builder::Module); our @EXPORT = qw(ok_regression); my $CLASS = __PACKAGE__; =head1 FUNCTIONS =head2 ok_regression This function requires two arguments: a CODE ref and a file path. The CODE ref is expected to return a SCALAR string which can be compared against previous runs. If the TEST_REGRESSION_GEN is set to a true value, then the CODE ref is run and the output written to the file. Otherwise the output of the file is compared against the contents of the file. There is a third optional argument which is the test name. =cut sub ok_regression { my $code_ref = shift; my $file = shift; my $test_name = shift; my $output = eval { &$code_ref(); }; my $tb = $CLASS->builder; if ($@) { $tb->diag($@); return $tb->ok( 0, $test_name ); } # generate the output files if required if ( $ENV{TEST_REGRESSION_GEN} ) { my $fh = FileHandle->new; $fh->open(">$file") || return $tb->ok( 0, "$test_name: cannot open $file" ); $fh->binmode; if ( length $output ) { $fh->print($output) || return $tb->ok( 0, "actual write failed: $file" ); } return $tb->ok( 1, $test_name ); } # compare the files return $tb->ok( 0, "$test_name: cannot read $file" ) unless -r $file; my $fh = FileHandle->new; $fh->open("<$file") || return $tb->ok( 0, "$test_name: cannot open $file" ); $fh->binmode; my $content = join '', (<$fh>); eq_or_diff( $output, $content, $test_name ); return $output eq $file; } =head1 ENVIRONMENT VARIABLES =head2 TEST_REGRESSION_GEN If the TEST_REGRESSION_GEN environment file is unset or false in a perl sense, then the named output files must exist and be readable and the test will run normally comparing the outputs of the CODE refs against the contents of those files. If the environment variable is true in a perl sense, then model output files will be overwritten with the output of the CODE ref. =head1 AUTHOR Nicholas Bamber, C<< >> =head1 BUGS Please report any bugs or feature requests to C, or through the web interface at L. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes. =head2 testing of STDERR The testing of stderr from this module is not as thorough as I would like. L allows turning off of stderr checking but not matching by regular expression. Handcrafted efforts currently fall foul of L. Still it is I believe adequately tested in terms of coverage. =head1 SUPPORT You can find documentation for this module with the perldoc command. perldoc Test::Regression You can also look for information at: =over 4 =item * RT: CPAN's request tracker L =item * AnnoCPAN: Annotated CPAN documentation L =item * CPAN Ratings L =item * Search CPAN L =back =head1 ACKNOWLEDGEMENTS =over =item Some documentation improvements have been suggested by toolic (http://perlmonks.org/?node_id=622051). =item Thanks to Filip Graliński for pointing out I need to test against output of zero length and providing a patch. =item Thanks to Christian Walde for pestering me about newline Windows compatibility issues and for providing a patch. =back =head1 COPYRIGHT & LICENSE Copyright 2009-10 Nicholas Bamber.
