NAME
Test::LWP::Recorder - Create an LWP UserAgent that records and plays
back sessions
VERSION
This document describes v0.1.0 of Test::LWP::Recorder - released June 07, 2011 as part of Test-LWP-Recorder.
SYNOPSIS
use Test::LWP::Recorder;
my $ua = Test::LWP::Recorder->new({
record => $ENV{LWP_RECORD},
cache_dir => 't/LWPCache',
filter_params => [qw(api_key api_secret password ssn)],
filter_header => [qw(Client-Peer Expires Client-Date Cache-Control)],
});
DESCRIPTION
This module creates a LWP UserAgent that records interactions to a test
drive. Setting the "record" parameter to true will cause it to record,
otherwise it plays back. It is designed for use in test suites.
In the case that a page is requested while in playback mode that was not
recorded while in record mode, a 404 will be returned.
There is another module that does basically the same thing called
LWPx::Record::DataSection. Please check this out before using this
module. It doesn't require a special UA, and stores the data in the DATA
section of your file. I use this module (a copy in inc/) for my test
suite!
METHODS
new ($options_ref, @lwp_options)
This creates a new object. Please see PARAMETERS for more details on
available options.
The returned object can be used just like any other LWP UserAgent
object.
request
This is overridden from LWP::UserAgent so we can do our magic.
PARAMETERS
record
Setting this to true puts the agent in record mode. False, in playback.
You usually want to set this to an environment variable.
cache_dir
This is the location to store the recordings. Filenames are all MD5
digests.
filter_params
This is an ArrayRef of POST or GET parameters to remove when recording.
The default for this is no filtering.
For example (using the $ua created in the synopsis):
# This is the request
my $resp = $ua->get('http://www.mybank.com?password=IAMSOCOOL&ssn=111-11-1111&method=transfer&destination=CH');
# Because password and ssn are filtered, these parameters will be removed
# from the object stored. If a tester in the future makes the following
# call:
#
my $resp = $ua->get('http://www.mybank.com?password=GUESSME&ssn=999-11-9999&method=transfer&destination=CH');
The cache result from the first will be used.
filter_header
A list of response headers not stored.
Default is [qw(Client-Peer Expires Client-Date Cache-Control)];
DIAGNOSTICS
Page requested that wasn't recorded
A page was requested while in playback mode that was not recorded in
record mode. A 404 object will be returned.
IMPORTANT NOTE
Please note that you should always put this in an inc directory
in your module when using it as part of a test suite. This is critical
because the filenames in the cache may change as new features are added
to the module.
Feel free to just copy the module file over and include it in your inc
(provided that your module uses Perl5, GPL, or Artistic license). If you
make any changes to it, please change the version number (the last
number).
ACKNOWLEDGMENTS
Thanks to motemen for LWPx::Record::DataSection which I use to test this
module (and bundle in the inc/ directory). It's a great module and a
simple approach.
BUGS AND LIMITATIONS
This works using a new UserAgent, which may not work for you.
Currently Cookies are ignored.
The filename scheme is pretty lame.
The test suite needs to be extended to include a POST example
