The C global state will +also be refreshed by calling C. For +example: + + plan $r, tests => 7; + +ties STDOUT to the request object C<$r>. + +If there is a last argument that doesn't belong to C +(which expects a balanced hash), it's used to decide whether to +continue with the test or to skip it all-together. This last argument +can be: + +=over + +=item * a C + +the test is skipped if the scalar has a false value. For example: + + plan tests => 5, 0; + +But this won't hint the reason for skipping therefore it's better to +use need(): + + plan tests => 5, + need 'LWP', + { "not Win32" => sub { $^O eq 'MSWin32'} }; + +see C for more info. + +=item * an C reference + +need_module() is called for each value in this array. The test is +skipped if need_module() returns false (which happens when at least +one C or Perl module from the list cannot be found). + +Watch out for case insensitive file systems or duplicate modules +with the same name. I.E. If you mean mod_env.c + need_module('mod_env.c') +Not + need_module('env') + +=item * a C reference + +the tests will be skipped if the function returns a false value. For +example: + + plan tests => 5, need_lwp; + +the test will be skipped if LWP is not available + +=back + +All other arguments are passed through to I as is. + +=item ok + +Same as I, see I documentation. + +=item sok + +Allows to skip a sub-test, controlled from the command line. The +argument to sok() is a CODE reference or a BLOCK whose return value +will be passed to ok(). By default behaves like ok(). If all sub-tests +of the same test are written using sok(), and a test is executed as: + + % ./t/TEST -v skip_subtest 1 3 + +only sub-tests 1 and 3 will be run, the rest will be skipped. + +=item skip + +Same as I, see I documentation. + +=item test_pm_refresh + +Normally called by I, this function will refresh +the global state maintained by I, allowing C and +friends to be called more than once per-process. This function is not +exported. + +=back + +Functions that can be used as a last argument to the extended plan(). +Note that for each C function there is a C equivalent +that performs the exact same function except that it is designed to +be used outside of C. C functions have the side effect +of generating skip messages, if the test is skipped. C functions +don't have this side effect. In other words, use C +with C to decide whether a test will run, but C +within test logic to adjust expectations based on older or newer +server versions. + +=over + +=item need_http11 + + plan tests => 5, need_http11; + +Require HTTP/1.1 support. + +=item need_ssl + + plan tests => 5, need_ssl; + +Require SSL support. + +Not exported by default. + +=item need_lwp + + plan tests => 5, need_lwp; + +Require LWP support. + +=item need_cgi + + plan tests => 5, need_cgi; + +Requires mod_cgi or mod_cgid to be installed. + +=item need_cache_disk + + plan tests => 5, need_cache_disk + +Requires mod_cache_disk or mod_disk_cache to be installed. + + +=item need_php + + plan tests => 5, need_php; + +Requires a PHP module to be installed (version 4 or 5). + +=item need_php4 + + plan tests => 5, need_php4; + +Requires a PHP version 4 module to be installed. + +=item need_imagemap + + plan tests => 5, need_imagemap; + +Requires a mod_imagemap or mod_imap be installed + +=item need_apache + + plan tests => 5, need_apache 2; + +Requires Apache 2nd generation httpd-2.x.xx + + plan tests => 5, need_apache 1; + +Requires Apache 1st generation (apache-1.3.xx) + +See also C. + +=item need_min_apache_version + +Used to require a minimum version of Apache. + +For example: + + plan tests => 5, need_min_apache_version("2.0.40"); + +requires Apache 2.0.40 or higher. + +=item need_apache_version + +Used to require a specific version of Apache. + +For example: + + plan tests => 5, need_apache_version("2.0.40"); + +requires Apache 2.0.40. + +=item need_min_apache_fix + +Used to require a particular micro version from corresponding minor release + +For example: + + plan tests => 5, need_min_apache_fix("2.0.40", "2.2.30", "2.4.18"); + +requires Apache 2.0.40 or higher. + +=item need_apache_mpm + +Used to require a specific Apache Multi-Processing Module. + +For example: + + plan tests => 5, need_apache_mpm('prefork'); + +requires the prefork MPM. + +=item need_perl + + plan tests => 5, need_perl 'iolayers'; + plan tests => 5, need_perl 'ithreads'; + +Requires a perl extension to be present, or perl compiled with certain +capabilities. + +The first example tests whether C is available, the second +whether: + + $Config{useithread} eq 'define'; + +=item need_min_perl_version + +Used to require a minimum version of Perl. + +For example: + + plan tests => 5, need_min_perl_version("5.008001"); + +requires Perl 5.8.1 or higher. + +=item need_fork + +Requires the perl built-in function C to be implemented. + +=item need_module + + plan tests => 5, need_module 'CGI'; + plan tests => 5, need_module qw(CGI Find::File); + plan tests => 5, need_module ['CGI', 'Find::File', 'cgid']; + +Requires Apache C and Perl modules. The function accept a list of +arguments or a reference to a list. + +In case of C modules, depending on how the module name was passed it +may pass through the following completions: + +=over + +=item 1 need_module 'proxy_http.c' + +If there is the I<.c> extension, the module name will be looked up as +is, i.e. I<'proxy_http.c'>. + +=item 2 need_module 'mod_cgi' + +The I<.c> extension will be appended before the lookup, turning it into +I<'mod_cgi.c'>. + +=item 3 need_module 'cgi' + +The I<.c> extension and I prefix will be added before the +lookup, turning it into I<'mod_cgi.c'>. + +=back + +=item need_min_module_version + +Used to require a minimum version of a module + +For example: + + plan tests => 5, need_min_module_version(CGI => 2.81); + +requires C version 2.81 or higher. + +Currently works only for perl modules. + +=item need + + plan tests => 5, + need 'LWP', + { "perl >= 5.8.0 and w/ithreads is required" => + ($Config{useperlio} && $] >= 5.008) }, + { "not Win32" => sub { $^O eq 'MSWin32' }, + "foo is disabled" => \&is_foo_enabled, + }, + 'cgid'; + +need() is more generic function which can impose multiple requirements +at once. All requirements must be satisfied. + +need()'s argument is a list of things to test. The list can include +scalars, which are passed to need_module(), and hash references. If +hash references are used, the keys, are strings, containing a reason +for a failure to satisfy this particular entry, the values are the +condition, which are satisfaction if they return true. If the value is +0 or 1, it used to decide whether the requirements very satisfied, so +you can mix special C functions that return 0 or 1. For +example: + + plan tests => 1, need 'Compress::Zlib', 'deflate', + need_min_apache_version("2.0.49"); + +If the scalar value is a string, different from 0 or 1, it's passed to +I. If the value is a code reference, it gets executed +at the time of check and its return value is used to check the +condition. If the condition check fails, the provided (in a key) +reason is used to tell user why the test was skipped. + +In the presented example, we require the presence of the C Perl +module, C, that we run under perl E= 5.7.3 on Win32. + +It's possible to put more than one requirement into a single hash +reference, but be careful that the keys will be different. + +It's also important to mention to avoid using: + + plan tests => 1, requirement1 && requirement2; + +technique. While test-wise that technique is equivalent to: + + plan tests => 1, need requirement1, requirement2; + +since the test will be skipped, unless all the rules are satisfied, +it's not equivalent for the end users. The second technique, deploying +C and a list of requirements, always runs all the requirement +checks and reports all the missing requirements. In the case of the +first technique, if the first requirement fails, the second is not +run, and the missing requirement is not reported. So let's say all the +requirements are missing Apache modules, and a user wants to satisfy +all of these and run the test suite again. If all the unsatisfied +requirements are reported at once, she will need to rebuild Apache +once. If only one requirement is reported at a time, she will have to +rebuild Apache as many times as there are elements in the C<&&> +statement. + +Also see plan(). + +=item under_construction + + plan tests => 5, under_construction; + +skip all tests, noting that the tests are under construction + +=item skip_reason + + plan tests => 5, skip_reason('my custom reason'); + +skip all tests. the reason you specify will be given at runtime. +if no reason is given a default reason will be used. + +=back + +=head1 Additional Configuration Variables + +=over 4 + +=item basic_config + + my $basic_cfg = Apache::Test::basic_config(); + $basic_cfg->write_perlscript($file, $content); + +C is similar to C, but doesn't contain any +httpd-specific information and should be used for operations that +don't require any httpd-specific knowledge. + +=item config + + my $cfg = Apache::Test::config(); + my $server_rev = $cfg->{server}->{rev}; + ... + +C gives an access to the configuration object. + +=item vars + + my $serverroot = Apache::Test::vars->{serverroot}; + my $serverroot = Apache::Test::vars('serverroot'); + my($top_dir, $t_dir) = Apache::Test::vars(qw(top_dir t_dir)); + +C gives an access to the configuration variables, otherwise +accessible as: + + $vars = Apache::Test::config()->{vars}; + +If no arguments are passed, the reference to the variables hash is +returned. If one or more arguments are passed the corresponding values +are returned. + +=back + +=head1 Test::More Integration + +There are a few caveats if you want to use I with +I instead of the default I backend. The first is +that I requires you to use its own C function +and not the one that ships with I. I also +defines C and C functions that are different, and +simply Cing both modules in your test script will lead to redefined +warnings for these subroutines. + +To assist I users we have created a special I +import tag, C<:withtestmore>, which will export all of the standard +I symbols into your namespace except the ones that collide +with I. + + use Apache::Test qw(:withtestmore); + use Test::More; + + plan tests => 1; # Test::More::plan() + + ok ('yes', 'testing ok'); # Test::More::ok() + +Now, while this works fine for standard client-side tests +(such as C), the more advanced features of I +require using I as the sole driver behind the scenes. + +Should you choose to use I as the backend for +server-based tests (such as C) you will +need to use the C<-withtestmore> action tag: + + use Apache::Test qw(-withtestmore); + + sub handler { + + my $r = shift; + + plan $r, tests => 1; # Test::More::plan() with + # Apache::Test features + + ok ('yes', 'testing ok'); # Test::More::ok() + } + +C<-withtestmore> tells I to use I +instead of I behind the scenes. Note that you are not +required to C yourself with the C<-withtestmore> +option and that the C 1> syntax +may have unexpected results. + +Note that I version 0.49, available within the +I 0.49 distribution on CPAN, or greater is required +to use this feature. + +Because I was initially developed using I as +the framework driver, complete I integration is +considered experimental at this time - it is supported as best as +possible but is not guaranteed to be as stable as the default I +interface at this time. + +=head1 Apache::TestToString Class + +The I class is used to capture I output +into a string. Example: + + Apache::TestToString->start; + + plan tests => 4; + + ok $data eq 'foo'; + + ... + + # $tests will contain the Test.pm output: 1..4\nok 1\n... + my $tests = Apache::TestToString->finish; + +=head1 SEE ALSO + +The Apache-Test tutorial: +L. + +L subclasses LWP::UserAgent and +exports a number of useful functions for sending request to the Apache test +server. You can then test the results of those requests. + +Use L in your F to set up your +distribution for testing. + +=head1 AUTHOR + +Doug MacEachern with contributions from Geoffrey Young, Philippe +M.
