6 Apache::TestRequest - Send requests to your Apache test server
7
9 use Apache::Test qw(ok have_lwp);
10 use Apache::TestRequest qw(GET POST);
11 use Apache::Constants qw(HTTP_OK);
12
13 plan tests => 1, have_lwp;
14
15 my $res = GET '/test.html';
16 ok $res->code == HTTP_OK, "Request is ok";
17
19 Apache::TestRequest provides convenience functions to allow you to make
20 requests to your Apache test server in your test scripts. It subclasses
21 "LWP::UserAgent", so that you have access to all if its methods, but
22 also exports a number of useful functions likely useful for majority of
23 your test requests. Users of the old "Apache::test" (or
24 "Apache::testold") module, take note! Herein lie most of the functions
25 you'll need to use to replace "Apache::test" in your test suites.
26
27 Each of the functions exported by "Apache::TestRequest" uses an
28 "LWP::UserAgent" object to submit the request and retrieve its results.
29 The return value for many of these functions is an HTTP::Response
30 object. See HTTP::Response for documentation of its methods, which you
31 can use in your tests. For example, use the "code()" and "content()"
32 methods to test the response code and content of your request. Using
33 "GET", you can perform a couple of tests using these methods like this:
34
35 use Apache::Test qw(ok have_lwp);
36 use Apache::TestRequest qw(GET POST);
37 use Apache::Constants qw(HTTP_OK);
38
39 plan tests => 2, have_lwp;
40
41 my $uri = "/test.html?foo=1&bar=2";
42 my $res = GET $uri;
43 ok $res->code == HTTP_OK, "Check that the request was OK";
44 ok $res->content eq "foo => 1, bar => 2", "Check its content";
45
46 Note that you can also use "Apache::TestRequest" with "Test::Builder"
47 and its derivatives, including "Test::More":
48
49 use Test::More;
50 # ...
51 is $res->code, HTTP_OK, "Check that the request was OK";
52 is $res->content, "foo => 1, bar => 2", "Check its content";
53
55 You can tell "Apache::TestRequest" what kind of "LWP::UserAgent" object
56 to use for its convenience functions with "user_agent()". This function
57 uses its arguments to construct an internal global "LWP::UserAgent"
58 object that will be used for all subsequent requests made by the
59 convenience functions. The arguments it takes are the same as for the
60 "LWP::UserAgent" constructor. See the "LWP::UserAgent" documentation
61 for a complete list.
62
63 The "user_agent()" function only creates the internal "LWP::UserAgent"
64 object the first time it is called. Since this function is called
65 internally by "Apache::TestRequest", you should always use the "reset"
66 parameter to force it to create a new global "LWP::UserAgent" Object:
67
68 Apache::TestRequest::user_agent(reset => 1, %params);
69
70 "user_agent()" differs from "LWP::UserAgent->new" in two additional
71 ways. First, it supports an additional parameter, "keep_alive", which
72 enables connection persistence, where the same connection is used to
73 process multiple requests (and, according to the "LWP::UserAgent"
74 documentation, has the effect of loading and enabling the new
75 experimental HTTP/1.1 protocol module).
76
77 And finally, the semantics of the "requests_redirectable" parameter is
78 different than for "LWP::UserAgent" in that you can pass it a boolean
79 value as well as an array for "LWP::UserAgent". To force
80 "Apache::TestRequest" not to follow redirects in any of its convenience
81 functions, pass a false value to "requests_redirectable":
82
83 Apache::TestRequest::user_agent(reset => 1,
84 requests_redirectable => 0);
85
86 If LWP is not installed, then you can still pass in an array reference
87 as "LWP::UserAgent" expects. "Apache::TestRequest" will examine the
88 array and allow redirects if the array contains more than one value or
89 if there is only one value and that value is not "POST":
90
91 # Always allow redirection.
92 my $redir = have_lwp() ? [qw(GET HEAD POST)] : 1;
93 Apache::TestRequest::user_agent(reset => 1,
94 requests_redirectable => $redir);
95
96 But note that redirection will not work with "POST" unless LWP is
97 installed. It's best, therefore, to check "have_lwp" before running
98 tests that rely on a redirection from "POST".
99
100 Sometimes it is desireable to have "Apache::TestRequest" remember
101 cookies sent by the pages you are testing and send them back to the
102 server on subsequent requests. This is especially necessary when
103 testing pages whose functionality relies on sessions or the presence of
104 preferences stored in cookies.
105
106 By default, "LWP::UserAgent" does not remember cookies between
107 requests. You can tell it to remember cookies between request by
108 adding:
109
110 Apache::TestRequest::user_agent(cookie_jar => {});
111
112 before issuing the requests.
113
115 "Apache::TestRequest" exports a number of functions that will likely
116 prove convenient for use in the majority of your request tests.
117
118 Optional Parameters
119 Each function also takes a number of optional arguments.
120
121 redirect_ok
122 By default a request will follow redirects retrieved from the
123 server. To prevent this behavior, pass a false value to a
124 "redirect_ok" parameter:
125
126 my $res = GET $uri, redirect_ok => 0;
127
128 Alternately, if all of your tests need to disable redirects, tell
129 "Apache::TestRequest" to use an "LWP::UserAgent" object that
130 disables redirects:
131
132 Apache::TestRequest::user_agent( reset => 1,
133 requests_redirectable => 0 );
134
135 cert
136 If you need to force an SSL request to use a particular SSL
137 certificate, pass the name of the certificate via the "cert"
138 parameter:
139
140 my $res = GET $uri, cert => 'my_cert';
141
142 content
143 If you need to add content to your request, use the "content"
144 parameter:
145
146 my $res = GET $uri, content => 'hello world!';
147
148 filename
149 The name of a local file on the file system to be sent to the
150 Apache test server via "UPLOAD()" and its friends.
151
152 The Functions
153 GET
154
155 my $res = GET $uri;
156
157 Sends a simple GET request to the Apache test server. Returns an
158 "HTTP::Response" object.
159
160 You can also supply additional headers to be sent with the request by
161 adding their name/value pairs after the "url" parameter, for example:
162
163 my $res = GET $url, 'Accept-Language' => 'de,en-us,en;q=0.5';
164
165 GET_STR
166
167 A shortcut function for "GET($uri)->as_string".
168
169 GET_BODY
170
171 A shortcut function for "GET($uri)->content".
172
173 GET_BODY_ASSERT
174
175 Use this function when your test is outputting content that you need to
176 check, and you want to make sure that the request was successful before
177 comparing the contents of the request. If the request was unsuccessful,
178 "GET_BODY_ASSERT" will return an error message. Otherwise it will
179 simply return the content of the request just as "GET_BODY" would.
180
181 GET_OK
182
183 A shortcut function for "GET($uri)->is_success".
184
185 GET_RC
186
187 A shortcut function for "GET($uri)->code".
188
189 GET_HEAD
190
191 Throws out the content of the request, and returns the string
192 representation of the request. Since the body has been thrown out, the
193 representation will consist solely of the headers. Furthermore,
194 "GET_HEAD" inserts a "#" at the beginning of each line of the return
195 string, so that the contents are suitable for printing to STDERR during
196 your tests without interfering with the workings of "Test::Harness".
197
198 HEAD
199
200 my $res = HEAD $uri;
201
202 Sends a HEAD request to the Apache test server. Returns an
203 "HTTP::Response" object.
204
205 HEAD_STR
206
207 A shortcut function for "HEAD($uri)->as_string".
208
209 HEAD_BODY
210
211 A shortcut function for "HEAD($uri)->content". Of course, this means
212 that it will likely return nothing.
213
214 HEAD_BODY_ASSERT
215
216 Use this function when your test is outputting content that you need to
217 check, and you want to make sure that the request was successful before
218 comparing the contents of the request. If the request was unsuccessful,
219 "HEAD_BODY_ASSERT" will return an error message. Otherwise it will
220 simply return the content of the request just as "HEAD_BODY" would.
221
222 HEAD_OK
223
224 A shortcut function for "GET($uri)->is_success".
225
226 HEAD_RC
227
228 A shortcut function for "GET($uri)->code".
229
230 HEAD_HEAD
231
232 Throws out the content of the request, and returns the string
233 representation of the request. Since the body has been thrown out, the
234 representation will consist solely of the headers. Furthermore,
235 "GET_HEAD" inserts a "#" at the beginning of each line of the return
236 string, so that the contents are suitable for printing to STDERR during
237 your tests without interfering with the workings of "Test::Harness".
238
239 PUT
240
241 my $res = PUT $uri;
242
243 Sends a simple PUT request to the Apache test server. Returns an
244 "HTTP::Response" object.
245
246 PUT_STR
247
248 A shortcut function for "PUT($uri)->as_string".
249
250 PUT_BODY
251
252 A shortcut function for "PUT($uri)->content".
253
254 PUT_BODY_ASSERT
255
256 Use this function when your test is outputting content that you need to
257 check, and you want to make sure that the request was successful before
258 comparing the contents of the request. If the request was unsuccessful,
259 "PUT_BODY_ASSERT" will return an error message. Otherwise it will
260 simply return the content of the request just as "PUT_BODY" would.
261
262 PUT_OK
263
264 A shortcut function for "PUT($uri)->is_success".
265
266 PUT_RC
267
268 A shortcut function for "PUT($uri)->code".
269
270 PUT_HEAD
271
272 Throws out the content of the request, and returns the string
273 representation of the request. Since the body has been thrown out, the
274 representation will consist solely of the headers. Furthermore,
275 "PUT_HEAD" inserts a "#" at the beginning of each line of the return
276 string, so that the contents are suitable for printing to STDERR during
277 your tests without interfering with the workings of "Test::Harness".
278
279 POST
280
281 my $res = POST $uri, [ arg => $val, arg2 => $val ];
282
283 Sends a POST request to the Apache test server and returns an
284 "HTTP::Response" object. An array reference of parameters passed as the
285 second argument will be submitted to the Apache test server as the POST
286 content. Parameters corresponding to those documented in Optional
287 Parameters can follow the optional array reference of parameters, or
288 after $uri.
289
290 To upload a chunk of data, simply use:
291
292 my $res = POST $uri, content => $data;
293
294 POST_STR
295
296 A shortcut function for "POST($uri, @args)->content".
297
298 POST_BODY
299
300 A shortcut function for "POST($uri, @args)->content".
301
302 POST_BODY_ASSERT
303
304 Use this function when your test is outputting content that you need to
305 check, and you want to make sure that the request was successful before
306 comparing the contents of the request. If the request was unsuccessful,
307 "POST_BODY_ASSERT" will return an error message. Otherwise it will
308 simply return the content of the request just as "POST_BODY" would.
309
310 POST_OK
311
312 A shortcut function for "POST($uri, @args)->is_success".
313
314 POST_RC
315
316 A shortcut function for "POST($uri, @args)->code".
317
318 POST_HEAD
319
320 Throws out the content of the request, and returns the string
321 representation of the request. Since the body has been thrown out, the
322 representation will consist solely of the headers. Furthermore,
323 "POST_HEAD" inserts a "#" at the beginning of each line of the return
324 string, so that the contents are suitable for printing to STDERR during
325 your tests without interfering with the workings of "Test::Harness".
326
327 UPLOAD
328
329 my $res = UPLOAD $uri, \@args, filename => $filename;
330
331 Sends a request to the Apache test server that includes an uploaded
332 file. Other POST parameters can be passed as a second argument as an
333 array reference.
334
335 "Apache::TestRequest" will read in the contents of the file named via
336 the "filename" parameter for submission to the server. If you'd rather,
337 you can submit use the "content" parameter instead of "filename", and
338 its value will be submitted to the Apache server as file contents:
339
340 my $res = UPLOAD $uri, undef, content => "This is file content";
341
342 The name of the file sent to the server will simply be "b". Note that
343 in this case, you cannot pass other POST arguments to "UPLOAD()" --
344 they would be ignored.
345
346 UPLOAD_BODY
347
348 A shortcut function for "UPLOAD($uri, @params)->content".
349
350 UPLOAD_BODY_ASSERT
351
352 Use this function when your test is outputting content that you need to
353 check, and you want to make sure that the request was successful before
354 comparing the contents of the request. If the request was unsuccessful,
355 "UPLOAD_BODY_ASSERT" will return an error message. Otherwise it will
356 simply return the content of the request just as "UPLOAD_BODY" would.
357
358 OPTIONS
359
360 my $res = OPTIONS $uri;
361
362 Sends an "OPTIONS" request to the Apache test server. Returns an
363 "HTTP::Response" object with the Allow header, indicating which methods
364 the server supports. Possible methods include "OPTIONS", "GET", "HEAD"
365 and "POST". This function thus can be useful for testing what options
366 the Apache server supports. Consult the HTTPD 1.1 specification,
367 section 9.2, at http://www.faqs.org/rfcs/rfc2616.html for more
368 information.
369
370 URL Manipulation Functions
371 "Apache::TestRequest" also includes a few helper functions to aid in
372 the creation of urls used in the functions above.
373
374 "module2path"
375
376 $path = Apache::TestRequest::module2path($module_name);
377
378 Convert a module name to a path, safe for use in the various request
379 methods above. e.g. "::" can't be used in URLs on win32. For example:
380
381 $path = Apache::TestRequest::module2path('Foo::Bar');
382
383 returns:
384
385 /Foo__Bar
386
387 "module2url"
388
389 $url = Apache::TestRequest::module2url($module);
390 $url = Apache::TestRequest::module2url($module, \%options);
391
392 Convert a module name to a full URL including the current
393 configurations "hostname:port" and sets "module" accordingly.
394
395 $url = Apache::TestRequest::module2url('Foo::Bar');
396
397 returns:
398
399 http://$hostname:$port/Foo__Bar
400
401 The default scheme used is "http". You can override this by passing
402 your preferred scheme into an optional second param. For example:
403
404 $module = 'MyTestModule::TestHandler';
405 $url = Apache::TestRequest::module2url($module, {scheme => 'https'});
406
407 returns:
408
409 https://$hostname:$port/MyTestModule__TestHandler
410
411 You may also override the default path with a path of your own:
412
413 $module = 'MyTestModule::TestHandler';
414 $url = Apache::TestRequest::module2url($module, {path => '/foo'});
415
416 returns:
417
418 http://$hostname:$port/foo
419
421 The following environment variables can affect the behavior of
422 "Apache::TestRequest":
423
424 APACHE_TEST_PRETEND_NO_LWP
425 If the environment variable "APACHE_TEST_PRETEND_NO_LWP" is set to
426 a true value, "Apache::TestRequest" will pretend that LWP is not
427 available so one can test whether the test suite will survive on a
428 system which doesn't have libwww-perl installed.
429
430 APACHE_TEST_HTTP_09_OK
431 If the environment variable "APACHE_TEST_HTTP_09_OK" is set to a
432 true value, "Apache::TestRequest" will allow HTTP/0.9 responses
433 from the server to proceed. The default behavior is to die if the
434 response protocol is not either HTTP/1.0 or HTTP/1.1.
435
437 Apache::Test is the main Apache testing module. Use it to set up your
438 tests, create a plan, and to ensure that you have the Apache version
439 and modules you need.
440
441 Use Apache::TestMM in your Makefile.PL to set up your distribution for
442 testing.
