test::regression
Test::Regression(3pm) User Contributed Perl Documentation Test::Regression(3pm)NAME
Test::Regression - Test library that can be run in two modes; one to generate outputs and a second to compare against them
VERSION
Version 0.05
SYNOPSIS
use Test::Regression;
ok_regression(sub {return "hello world"}, "t/out/hello_world.txt");
DESCRIPTION
Using the various Test:: modules you can compare the output of a function against what you expect. 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.
EXPORT
ok_regression
FUNCTIONS
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.
ENVIRONMENT VARIABLES
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.

BUGS
Please report any bugs or feature requests to "bug-test-regression at rt.cpan.org", or through the web interface at
<http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Test-Regression>. I will be notified, and then you'll automatically be notified of
progress on your bug as I make changes.
testing of STDERR
The testing of stderr from this module is not as thorough as I would like. Test::Builder::Tester allows turning off of stderr checking but
not matching by regular expression. Handcrafted efforts currently fall foul of Test::Harness. Still it is I believe adequately tested in
terms of coverage.
SUPPORT
You can find documentation for this module with the perldoc command.

ACKNOWLEDGEMENTS
Some documentation improvements have been suggested by toolic (http://perlmonks.org/?node_id=622051).
Thanks to Filip GraliXski for pointing out I need to test against output of zero length and providing a patch.
