Test::Apache::RewriteRules - Testing Apache's Rewrite Rules


  use Test::Apache::RewriteRules;

  my $apache = Test::Apache::RewriteRules->new;
     $apache->add_backend(name => 'ReverseProxyedHost1');
     $apache->add_backend(name => 'ReverseProxyedHost2');

  # testing rewritten result
  $apache->is_host_path('/foo/aaa', 'ReverseProxyedHost1', '/aaa',
                        'Handled by reverse-proxyed host 1');
  $apache->is_host_path('/bar/bbb', 'ReverseProxyedHost2', '/bbb',
                        'Handled by reverse-proxyed host 2');
  $apache->is_host_path('/baz', '', '/baz',
                        'Handled by the proxy itself');

  # testing redirection
  $apache->is_redirect('/quux/xxx', 'http://external.test/xxx');

  # rewrite rules in `apache.rewrite.conf' passed in above
  RewriteEngine on
  RewriteRule /foo/(.*)  http://%{ENV:ReverseProxyedHost1}/$1 [P,L]
  RewriteRule /bar/(.*)  http://%{ENV:ReverseProxyedHost2}/$1 [P,L]
  RewriteRule /quux/(.*) http://external.test/$1 [R,L]


The Test::Apache::RewriteRules module sets up Apache HTTPD server for the purpose of testing of a set of RewriteRules in apache.conf Apache configuration.



      $is_available = Test::Apache::RewriteRules->available;

    Returns whether the features provided by this module is available or not. At the time of writing, it returns false is no Apache binary is found.

new ([%args])

      $apache = Test::Apache::RewriteRules->new;

    Returns a new instance of the class.

    If a ref to hash as a value of %args keyed as 'apache_options' passed in, it's passed straight into Test::Httpd::Apache2-new()>.

add_backend (%backend)

      $apache->add_backend(name => HOST_NAME);

    Registers a backend (i.e. a host that handles HTTP requests). An environment variable whose name is HOST_NAME will be defined in the automatically-generated Apache configuration file such that it can be used in rewrite rules.

copy_config (config_file, \@patterns)

          $config_file, [
              PATTERN1 => REPLACE1,
              PATTERN2 => REPLACE2,

    Copies the file represented by $config_file into the temporary directory and optionally replaces its content by applying patterns.

    Patterns, if specified, must be an array reference containing string or regular expression followed by string or code reference. If the replaced string is specified as a code reference, its return value is used for the replacement. If the pattern is specified as a regular expression and the replaced string is specified as a code reference, the code reference can use $1, $2, ... to access to captured substrings.

rewrite_conf ($rewrite_conf)


    Sets $rewrite_conf file that represents the path to the RewriteRules' part of the Apache configuration to test.



    Boots the Apache process. It should be invoked before any is_host_path call.

is_host_path ($request_path, $expected_host_name, $expected_path, [$name])

      $apache->is_host_path($request_path, $expected_host_name, $expected_path, $name);

    Checks whether the request for $request_path is handled by host $expected_host_name with path $expected_path. The host name should be specified by the name registered using add_backend method, or the empty string if the request would be handled by the reverse proxy (i.e. the rewriting host) itself.

    This method acts as a test function of Test::Builder or Test::More. The argument $name, if specified, represents the name of the test.

is_redirect ($request_path, $expected_redirect_url, [$name, %args])

      $apache->is_redirect($request_path, $expected_redirect_url, $name, code => 301);

    Checks whether the request for $request_path is HTTP-redirected to the $expected_redirect_url.

    This method acts as a test function of Test::Builder or Test::More. The argument $name, if specified, represents the name of the test.

    Optionally, you can specify the expected HTTP status code. The default status code is 302 (Found).



    Shuts down the Apache process.


You can set the expected client environment used to evaluate is_host_path and is_redirect by using Test::Apache::RewriteRules::ClientEnvs module.

Where $request_path is expected, the host of the request (used in the Host: request header field) can be specified by prepending // followed by host (hostname possibly followed by : and port number) before the real path.


See t/*.t and t/conf/*.conf.
