5 # Privoxy-Regression-Test
7 # A regression test "framework" for Privoxy. For documentation see:
8 # perldoc privoxy-regression-test.pl
10 # $Id: privoxy-regression-test.pl,v 1.2 2008/01/21 18:43:16 fabiankeil Exp $
14 # - Update documentation
15 # - Validate HTTP times.
16 # - Understand default.action.master comment syntax
17 # and verify that we actually block and unblock what
18 # the comments claim we do.
19 # - Implement a HTTP_VERSION directive or allow to
20 # specify whole request lines.
21 # - Support filter regression tests.
22 # - Add option to fork regression tests and run them in parallel,
23 # possibly optional forever.
24 # - Document magic Expect Header values
25 # - Internal fuzz support?

1309 Privoxy-Regression-Test is supposed to one day become
1310 a regression test suite for Privoxy. It's not quite there
1311 yet, however, and can currently only test client header
1312 actions and check the returned status code for requests
1315 Client header actions are tested by requesting
1316 B<http://config.privoxy.org/show-request> and checking whether
1317 or not Privoxy modified the original request as expected.
1319 The original request contains both the header the action-to-be-tested
1320 acts upon and an additional tagger-triggering header that enables
1323 =head1 CONFIGURATION FILE SYNTAX
1325 Privoxy-Regression-Test's configuration is embedded in
1326 Privoxy action files and loaded through Privoxy's web interface.
1328 It makes testing a Privoxy version running on a remote system easier
1329 and should prevent you from updating your tests without updating Privoxy's
1330 configuration accordingly.
1332 A client-header-action test section looks like this:
1334 # Set Header = Referer: http://www.example.org.zwiebelsuppe.exit/
1335 # Expect Header = Referer: http://www.example.org/
1336 {+client-header-filter{hide-tor-exit-notation} -hide-referer}
1337 TAG:^client-header-filter\{hide-tor-exit-notation\}$
1339 The example above causes Privoxy-Regression-Test to set
1340 the header B<Referer: http://www.example.org.zwiebelsuppe.exit/>
1341 and to expect it to be modified to
1342 B<Referer: http://www.example.org/>.
1344 When testing this section, Privoxy-Regression-Test will set the header
1345 B<X-Privoxy-Control: client-header-filter{hide-tor-exit-notation}>
1346 causing the B<privoxy-control> tagger to create the tag
1347 B<client-header-filter{hide-tor-exit-notation}> which will finally
1348 cause Privoxy to enable the action section.
1350 Note that the actions itself are only used by Privoxy,
1351 Privoxy-Regression-Test ignores them and will be happy
1352 as long as the expectations are satisfied.
1354 A fetch test looks like this:
1356 # Fetch Test = http://p.p/user-manual
1357 # Expect Status Code = 302
1359 It tells Privoxy-Regression-Test to request B<http://p.p/user-manual>
1360 and to expect a response with the HTTP status code B<302>. Obviously that's
1361 not a very thorough test and mainly useful to get some code coverage
1362 for Valgrind or to verify that the templates are installed correctly.
1364 If you want to test CGI pages that require a trusted
1365 referer, you can use:
1367 # Trusted CGI Request = http://p.p/edit-actions
1369 It works like ordinary fetch tests, but sets the referer
1370 header to a trusted value.
1372 If no explicit status code expectation is set, B<200> is used.
1374 Additionally all tests have test levels to let the user
1375 control which ones to execute (see I<OPTIONS> below).
1376 Test levels are either set with the B<Level> directive,
1377 or implicitly through the test type.
1379 Fetch tests default to level 6, tests for trusted
1380 CGI requests to level 3 and client-header-action tests
1385 B<--debug bitmask> Add the bitmask provided as integer
1386 to the debug settings.
1388 B<--fuzzer-feeding> Ignore some errors that would otherwise
1389 cause Privoxy-Regression-Test to abort the test because
1390 they shouldn't happen in normal operation. This option is
1391 intended to be used if Privoxy-Regression-Test is only
1392 used to feed a fuzzer in which case there's a high chance
1393 that Privoxy gets an invalid request and returns an error
1396 B<--help> Shows available command line options.
1398 B<--level level> Only execute tests with the specified B<level>.
1400 B<--loop count> Loop through the regression tests B<count> times.
1401 Useful to feed a fuzzer, or when doing stress tests with
1402 several Privoxy-Regression-Test instances running at the same
1405 B<--max-level max-level> Only execute tests with a B<level>
1406 below or equal to the numerical B<max-level>.
1408 B<--max-time max-time> Give Privoxy B<max-time> seconds
1409 to return data. Increasing the default may make sense when
1410 Privoxy is run through Valgrind, decreasing the default may
1411 make sense when Privoxy-Regression-Test is used to feed
1414 B<--min-level min-level> Only execute tests with a B<level>
1415 above or equal to the numerical B<min-level>.
1417 B<--privoxy-address proxy-address> Privoxy's listening address.
1418 If it's not set, the value of the environment variable http_proxy
1419 will be used. B<proxy-address> has to be specified in http_proxy
1422 B<--retries retries> Retry B<retries> times.
1424 B<--silent> Don't log succesful test runs.
1426 B<--version> Print version and exit.
1428 The second dash is optional, options can be shortened,
1429 as long as there are no ambiguities.
1431 =head1 PRIVOXY CONFIGURATION
1433 Privoxy-Regression-Test is shipped with B<regression-tests.action>
1434 which aims to test all official client-header modifying actions
1435 and can be used to verify that the templates and the user manual
1436 files are installed correctly.
1438 To use it, it has to be copied in Privoxy's configuration
1439 directory, and afterwards referenced in Privoxy's configuration
1442 actionsfile regression-tests.action
1444 In general, its tests are supposed to work without changing
1445 any other action files, unless you already added lots of
1446 taggers yourself. If you are using taggers that cause problems,
1447 you might have to temporary disable them for Privoxy's CGI pages.
1449 Some of the regression tests rely on Privoxy features that
1450 may be disabled in your configuration. Tests with a level below
1451 7 are supposed to work with all Privoxy configurations (provided
1452 you didn't build with FEATURE_GRACEFUL_TERMINATION).
1454 Tests with level 9 require Privoxy to deliver the User Manual,
1455 tests with level 12 require the CGI editor to be enabled.
1459 Expect the configuration file syntax to change with future releases.
1463 As Privoxy's B<show-request> page only shows client headers,
1464 Privoxy-Regression-Test can't use it to test Privoxy actions
1465 that modify server headers.
1467 As Privoxy-Regression-Test relies on Privoxy's tag feature to
1468 control the actions to test, it currently only works with
1469 Privoxy 3.0.7 or later.
1471 At the moment Privoxy-Regression-Test fetches Privoxy's
1472 configuration page through I<curl>(1), therefore you have to
1473 have I<curl> installed, otherwise you won't be able to run
1474 Privoxy-Regression-Test in a meaningful way.
