Apache::Test(3pm) |
 |
Apache::Test − Test.pm wrapper with helpers for testing Apache
use Apache::Test;
Apache::Test is a wrapper around the standard "Test.pm" with helpers for testing an Apache server.
plan
This function is a wrapper around "Test::plan":
plan tests => 3;
just like using Test.pm, plan 3 tests.
If the first argument is an object, such as an "Apache::RequestRec" object, "STDOUT" will be tied to it. The "Test.pm" global state will also be refreshed by calling "Apache::Test::test_pm_refresh". For example:
plan $r, tests => 7;
ties STDOUT to the request object $r.
If there is a
last argument that doesn’t belong to
"Test::plan" (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:
• a "SCALAR"
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 have():
plan tests => 5,
have ’LWP’,
{ "perl >= 5.7.3 is required" => sub { $] >= 5.007003 } };
see have() for more info.
• an "ARRAY" reference
have_module() is called for each value in this array. The test is skipped if have_module() returns false (which happens when at least one C or Perl module from the list cannot be found).
• a "CODE" reference
the tests will be skipped if the function returns a false value. For example:
plan tests => 5, \&have_lwp;
the test will be skipped if LWP is not available
All other arguments are passed through to Test::plan as is.

ok |
Same as Test::ok, see Test.pm documentation. | ||
|
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.
skip
Same as Test::skip, see Test.pm documentation.
test_pm_refresh
Normally called by Apache::Test::plan, this function will refresh the global state maintained by Test.pm, allowing "plan" and friends to be called more than once per−process. This function is not exported.
Functions that can be used as a last argument to the extended plan():
plan tests => 5, &have_http11;
Require HTTP/1 .1 support.
have_ssl
plan tests => 5, &have_ssl;
Require SSL support.
Not exported by default.
have_lwp
plan tests => 5, &have_lwp;
Require LWP support.
have_cgi
plan tests => 5, &have_cgi;
Requires mod_cgi or mod_cgid to be installed.
have_apache
plan tests => 5, have_apache 2;
Requires Apache 2nd generation httpd−2.x.xx
plan tests => 5, have_apache 1;
Requires Apache 1st generation (apache−1.3.xx)
See also "have_min_apache_version()".
have_min_apache_version
Used to require a minimum version of Apache.
For example:
plan tests => 5, have_min_apache_version("2.0.40");
requires Apache 2.0.40 or higher.
have_apache_version
Used to require a specific version of Apache.
For example:
plan tests => 5, have_apache_version("2.0.40");
requires Apache 2.0.40.
have_perl
plan tests => 5, have_perl ’iolayers’; plan tests => 5, have_perl ’ithreads’;
Requires a perl extension to be present, or perl compiled with certain capabilities.
The first example tests whether "PerlIO" is available, the second whether:
$Config{useithread} eq ’define’;
have_module
plan tests => 5, have_module ’CGI’; plan tests => 5, have_module qw(CGI Find::File); plan tests => 5, have_module [’CGI’, ’Find::File’, ’cgid’];
Requires Apache C and Perl modules. The function accept a list of arguments or a reference to a list.
In case of C
modules, depending on how the module name was passed it may
pass through the following completions:
1 have_module ’proxy_http.c’
If there is the .c extension, the module name will be looked up as is, i.e. ’proxy_http.c’.
2 have_module ’mod_cgi’
The .c extension will be appended before the lookup, turning it into ’mod_cgi.c’.
3 have_module ’cgi’
The .c extension and mod_ prefix will be added before the lookup, turning it into ’mod_cgi.c’.
have
plan tests => 5,
have ’LWP’,
{ "perl >= 5.8.0 is required" => ($] >= 5.008) },
{ "not Win32" => sub { $^O eq ’MSWin32’ },
"foo is disabled" => \&is_foo_enabled,
},
’cgid’;
have() is more generic function which can impose multiple requirements at once. All requirements must be satisfied.
have()’s argument is a list of things to test. The list can include scalars, which are passed to have_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 valuees are the condition, which are satisfaction if they return true. If the value is a scalar it’s used as is. 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 presense of the "LWP" Perl module, "mod_cgid", that we run under perl >= 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.
Also see plan().
The Apache::TestToString class is used to capture Test.pm 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;
