7 # A regression test "framework" for Privoxy. For documentation see:

10 # $Id: privoxy-regression-test.pl,v 1.81 2011/10/30 16:22:29 fabiankeil Exp $
14 # - Update documentation
15 # - Validate HTTP times.
16 # - Implement a HTTP_VERSION directive or allow to
17 # specify whole request lines.
18 # - Support filter regression tests.
19 # - Document magic Expect Header values
20 # - Internal fuzz support?

1794 URLs and verify which actions are applied to them.
1796 Client header actions are tested by requesting
1797 B<http://p.p/show-request> and checking whether
1798 or not Privoxy modified the original request as expected.
1800 The original request contains both the header the action-to-be-tested
1801 acts upon and an additional tagger-triggering header that enables
1804 Applied actions are checked through B<http://p.p/show-url-info>.
1806 =head1 CONFIGURATION FILE SYNTAX
1808 Privoxy-Regression-Test's configuration is embedded in
1809 Privoxy action files and loaded through Privoxy's web interface.
1811 It makes testing a Privoxy version running on a remote system easier
1812 and should prevent you from updating your tests without updating Privoxy's
1813 configuration accordingly.
1815 A client-header-action test section looks like this:
1817 # Set Header = Referer: http://www.example.org.zwiebelsuppe.exit/
1818 # Expect Header = Referer: http://www.example.org/
1819 {+client-header-filter{hide-tor-exit-notation} -hide-referer}
1820 TAG:^client-header-filter\{hide-tor-exit-notation\}$
1822 The example above causes Privoxy-Regression-Test to set
1823 the header B<Referer: http://www.example.org.zwiebelsuppe.exit/>
1824 and to expect it to be modified to
1825 B<Referer: http://www.example.org/>.
1827 When testing this section, Privoxy-Regression-Test will set the header
1828 B<X-Privoxy-Control: client-header-filter{hide-tor-exit-notation}>
1829 causing the B<privoxy-control> tagger to create the tag
1830 B<client-header-filter{hide-tor-exit-notation}> which will finally
1831 cause Privoxy to enable the action section.
1833 Note that the actions itself are only used by Privoxy,
1834 Privoxy-Regression-Test ignores them and will be happy
1835 as long as the expectations are satisfied.
1837 A fetch test looks like this:
1839 # Fetch Test = http://p.p/user-manual
1840 # Expect Status Code = 302
1842 It tells Privoxy-Regression-Test to request B<http://p.p/user-manual>
1843 and to expect a response with the HTTP status code B<302>. Obviously that's
1844 not a very thorough test and mainly useful to get some code coverage
1845 for Valgrind or to verify that the templates are installed correctly.
1847 If you want to test CGI pages that require a trusted
1848 referer, you can use:
1850 # Trusted CGI Request = http://p.p/edit-actions
1852 It works like ordinary fetch tests, but sets the referer
1853 header to a trusted value.
1855 If no explicit status code expectation is set, B<200> is used.
1857 To verify that a URL is blocked, use:
1859 # Blocked URL = http://www.example.com/blocked
1861 To verify that a specific set of actions is applied to an URL, use:
1863 # Sticky Actions = +block{foo} +handle-as-empty-document -handle-as-image
1864 # URL = http://www.example.org/my-first-url
1866 The sticky actions will be checked for all URLs below it
1867 until the next sticky actions directive.
1869 To verify that requests for a URL get redirected, use:
1871 # Redirected URL = http://www.example.com/redirect-me
1872 # Redirect Destination = http://www.example.org/redirected
1876 All tests have test levels to let the user
1877 control which ones to execute (see I<OPTIONS> below).
1878 Test levels are either set with the B<Level> directive,
1879 or implicitly through the test type.
1881 Redirect tests default to level 108, block tests to level 7,
1882 fetch tests to level 6, "Sticky Actions" tests default to
1883 level 5, tests for trusted CGI requests to level 3 and
1884 client-header-action tests to level 1.
1886 The current redirect test level is above the default
1887 max-level value as failed tests will result in outgoing
1888 connections. Use the B<--max-level> option to run them
1893 B<--debug bitmask> Add the bitmask provided as integer
1894 to the debug settings.
1896 B<--forks forks> Number of forks to start before executing
1897 the regression tests. This is mainly useful for stress-testing.
1899 B<--fuzzer-address> Listening address used when executing
1900 the regression tests. Useful to make sure that the requests
1901 to load the regression tests don't fail due to fuzzing.
1903 B<--fuzzer-feeding> Ignore some errors that would otherwise
1904 cause Privoxy-Regression-Test to abort the test because
1905 they shouldn't happen in normal operation. This option is
1906 intended to be used if Privoxy-Regression-Test is only
1907 used to feed a fuzzer in which case there's a high chance
1908 that Privoxy gets an invalid request and returns an error
1911 B<--help> Shows available command line options.
1913 B<--header-fuzzing> Modifies linear white space in
1914 headers in a way that should not affect the test result.
1916 B<--level level> Only execute tests with the specified B<level>.
1918 B<--local-test-file test-file> Do not get the tests
1919 through Privoxy's web interface, but use a single local
1920 file. Not recommended for testing Privoxy, but can be useful
1921 to "misappropriate" Privoxy-Regression-Test to test other
1922 stuff, like webserver configurations.
1924 B<--loop count> Loop through the regression tests B<count> times.
1925 Useful to feed a fuzzer, or when doing stress tests with
1926 several Privoxy-Regression-Test instances running at the same
1929 B<--max-level max-level> Only execute tests with a B<level>
1930 below or equal to the numerical B<max-level>.
1932 B<--max-time max-time> Give Privoxy B<max-time> seconds
1933 to return data. Increasing the default may make sense when
1934 Privoxy is run through Valgrind, decreasing the default may
1935 make sense when Privoxy-Regression-Test is used to feed
1938 B<--min-level min-level> Only execute tests with a B<level>
1939 above or equal to the numerical B<min-level>.
1941 B<--privoxy-address proxy-address> Privoxy's listening address.
1942 If it's not set, the value of the environment variable http_proxy
1943 will be used. B<proxy-address> has to be specified in http_proxy
1946 B<--retries retries> Retry B<retries> times.
1948 B<--test-number test-number> Only run the test with the specified
1951 B<--show-skipped-tests> Log skipped tests even if verbose mode is off.
1953 B<--shuffle-tests> Shuffle test sections and their tests before
1954 executing them. When combined with B<--forks>, this can increase
1955 the chances of detecting race conditions. Of course some problems
1956 are easier to detect without this option.
1958 B<--sleep-time seconds> Wait B<seconds> between tests. Useful when
1959 debugging issues with systems that don't log with millisecond precision.
1961 B<--verbose> Log successful tests as well. By default only
1962 the failures are logged.
1964 B<--version> Print version and exit.
1966 The second dash is optional, options can be shortened,
1967 as long as there are no ambiguities.
1969 =head1 PRIVOXY CONFIGURATION
1971 Privoxy-Regression-Test is shipped with B<regression-tests.action>
1972 which aims to test all official client-header modifying actions
1973 and can be used to verify that the templates and the user manual
1974 files are installed correctly.
1976 To use it, it has to be copied in Privoxy's configuration
1977 directory, and afterwards referenced in Privoxy's configuration
1980 actionsfile regression-tests.action
1982 In general, its tests are supposed to work without changing
1983 any other action files, unless you already added lots of
1984 taggers yourself. If you are using taggers that cause problems,
1985 you might have to temporary disable them for Privoxy's CGI pages.
1987 Some of the regression tests rely on Privoxy features that
1988 may be disabled in your configuration. Tests with a level below
1989 7 are supposed to work with all Privoxy configurations (provided
1990 you didn't build with FEATURE_GRACEFUL_TERMINATION).
1992 Tests with level 9 require Privoxy to deliver the User Manual,
1993 tests with level 12 require the CGI editor to be enabled.
1997 Expect the configuration file syntax to change with future releases.
2001 As Privoxy's B<show-request> page only shows client headers,
2002 Privoxy-Regression-Test can't use it to test Privoxy actions
2003 that modify server headers.
2005 As Privoxy-Regression-Test relies on Privoxy's tag feature to
2006 control the actions to test, it currently only works with
2007 Privoxy 3.0.7 or later.
2009 At the moment Privoxy-Regression-Test fetches Privoxy's
2010 configuration page through I<curl>(1), therefore you have to
2011 have I<curl> installed, otherwise you won't be able to run
2012 Privoxy-Regression-Test in a meaningful way.
