SYNOPSIS
# In Makefile.PL
use Apache::testold;
my %params = Apache::testold->get_test_params();
Apache::testold->write_httpd_conf(%params, include => $more_directives);
*MY::test = sub { Apache::testold->MM_test(%params) };
# In t/*.t script (or test.pl)
use Apache::testold qw(skip_test have_httpd);
skip_test unless have_httpd;

DESCRIPTION
This module helps authors of Apache::* modules write test suites that
can query an actual running Apache server with mod_perl and their mod-
ules loaded into it. Its functionality is generally separated into
methods that go in a Makefile.PL to configure, start, and stop the
server, and methods that go in one of the test scripts to make HTTP
queries and manage the results.
METHODSget_test_params()
This will ask the user a few questions about where the httpd binary is,
and what user/group/port should be used when running the server. It
will return a hash of the information it discovers. This hash is suit-
able for passing to the "write_httpd_conf()" method.
write_httpd_conf(%params)
This will write a basic "httpd.conf" file suitable for starting a HTTP
server during the 'make test' stage. A hash of key/value pairs that
affect the written file can be passed as arguments. The following keys
are recognized:
* conf_file
The path to the file that will be created. Default is
't/httpd.conf'.
* port
The port that the Apache server will listen on.
* user
The user that the Apache server will run as.
* group
The group that the Apache server will run as.
* include
Any additional text you want added at the end of the config file.
Typically you'll have some "PerlModule" and "Perl*Handler" direc-
tives to pass control to the module you're testing. The "blib/"
directories will be added to the @INC path when searching for mod-
ules, so that's nice.
MM_test(%params)
This method helps write a Makefile that supports running a web server
during the 'make test' stage. When you execute 'make test', 'make'
will run 'make start_httpd', 'make run_tests', and 'make kill_httpd' in
sequence. You can also run these commands independently if you want.
Pass the hash of parameters returned by "get_test_params()" as an argu-
ment to "MM_test()".
To patch into the ExtUtils::MakeMaker wizardry (voodoo?), typically
you'll do the following in your Makefile.PL:
*MY::test = sub { Apache::testold->MM_test(%params) };
fetch
Apache::testold->fetch($request);
Apache::testold->fetch($user_agent, $request);
Call this method in a test script in order to fetch a page from the
running web server. If you pass two arguments, the first should be an
LWP::UserAgent object, and the second should specify the request to
make of the server. If you only pass one argument, it specifies the
request to make.
The request can be specified either by a simple string indicating the
URI to fetch, or by a hash reference, which gives you more control over
the request. The following keys are recognized in the hash:
* uri
The URI to fetch from the server. If the URI does not begin with
"http", we prepend "http://localhost:$PORT" so that we make
requests of the test server.
* method
The request method to use. Default is 'GET'.
* content
The request content body. Typically used to simulate HTML fill-out
form submission for POST requests. Default is null.
* headers
A hash of headers you want sent with the request. You might use
this to send cookies or provide some application-specific header.
If you don't provide a 'headers' parameter and you set the 'method' to
'POST', then we assume that you're trying to simulate HTML form submis-
sion and we add a 'Content_Type' header with a value of 'applica-
tion/x-www-form-urlencoded'.
In a scalar context, fetch() returns the content of the web server's
response. In a list context, fetch() returns the content and the
HTTP::Response object itself. This can be handy if you need to check
the response headers, or the HTTP return code, or whatever.
static_modules
Example: $mods = Apache::testold->static_modules('/path/to/httpd');
This method returns a hashref whose keys are all the modules statically
compiled into the given httpd binary. The corresponding values are all
1.
EXAMPLES
No good examples yet. Example submissions are welcome. In the mean-
time, see <http://forum.swarthmore.edu/~ken/modules/Apache-AuthCookie/>
, which I'm retrofitting to use Apache::testold.
TO DO
The MM_test method doesn't try to be very smart, it just writes the
text that seems to work in my configuration. I am morally against
using the 'make' command for installing Perl modules (though of course
I do it anyway), so I haven't looked into this very much. Send bug
reports or better (patches).
I've got lots of code in my Apache::AuthCookie module (etc.) that
assists in actually making the queries of the running server. I plan
to add that to this module, but first I need to compare what's already
here that does the same stuff.
KUDOS
To Doug MacEachern for writing the first version of this module.
To caelum@debian.org (Rafael Kitover) for contributing the code to
parse existing httpd.conf files for --enable-shared=max and DSOs.
CAVEATS
Except for making sure that the mod_perl distribution itself can run
'make test' okay, I haven't tried very hard to keep compatibility with
older versions of this module. In particular MM_test() has changed and
probably isn't usable in the old ways, since some of its assumptions
are gone. But none of this was ever documented, and MM_test() doesn't
seem to actually be used anywhere in the mod_perl disribution, so I
don't feel so bad about it.
