5 # Privoxy-Regression-Test
7 # A regression test "framework" for Privoxy. For documentation see:
8 # perldoc privoxy-regression-test.pl
12 # - Update documentation
13 # - Validate HTTP times.
14 # - Implement a HTTP_VERSION directive or allow to
15 # specify whole request lines.
16 # - Support filter regression tests.
17 # - Document magic Expect Header values
18 # - Internal fuzz support?

1855 Privoxy-Regression-Test is supposed to one day become
1856 a regression test suite for Privoxy. It's not quite there
1857 yet, however, and can currently only test header actions,
1858 check the returned status code for requests to arbitrary
1859 URLs and verify which actions are applied to them.
1861 Client header actions are tested by requesting
1862 B<http://p.p/show-request> and checking whether
1863 or not Privoxy modified the original request as expected.
1865 The original request contains both the header the action-to-be-tested
1866 acts upon and an additional tagger-triggering header that enables
1869 Applied actions are checked through B<http://p.p/show-url-info>.
1871 =head1 CONFIGURATION FILE SYNTAX
1873 Privoxy-Regression-Test's configuration is embedded in
1874 Privoxy action files and loaded through Privoxy's web interface.
1876 It makes testing a Privoxy version running on a remote system easier
1877 and should prevent you from updating your tests without updating Privoxy's
1878 configuration accordingly.
1880 A client-header-action test section looks like this:
1882 # Set Header = Referer: http://www.example.org.zwiebelsuppe.exit/
1883 # Expect Header = Referer: http://www.example.org/
1884 {+client-header-filter{hide-tor-exit-notation} -hide-referer}
1885 TAG:^client-header-filter\{hide-tor-exit-notation\}$
1887 The example above causes Privoxy-Regression-Test to set
1888 the header B<Referer: http://www.example.org.zwiebelsuppe.exit/>
1889 and to expect it to be modified to
1890 B<Referer: http://www.example.org/>.
1892 When testing this section, Privoxy-Regression-Test will set the header
1893 B<X-Privoxy-Control: client-header-filter{hide-tor-exit-notation}>
1894 causing the B<privoxy-control> tagger to create the tag
1895 B<client-header-filter{hide-tor-exit-notation}> which will finally
1896 cause Privoxy to enable the action section.
1898 Note that the actions itself are only used by Privoxy,
1899 Privoxy-Regression-Test ignores them and will be happy
1900 as long as the expectations are satisfied.
1902 A fetch test looks like this:
1904 # Fetch Test = http://p.p/user-manual
1905 # Expect Status Code = 302
1907 It tells Privoxy-Regression-Test to request B<http://p.p/user-manual>
1908 and to expect a response with the HTTP status code B<302>. Obviously that's
1909 not a very thorough test and mainly useful to get some code coverage
1910 for Valgrind or to verify that the templates are installed correctly.
1912 If you want to test CGI pages that require a trusted
1913 referer, you can use:
1915 # Trusted CGI Request = http://p.p/edit-actions
1917 It works like ordinary fetch tests, but sets the referer
1918 header to a trusted value.
1920 If no explicit status code expectation is set, B<200> is used.
1922 To verify that a URL is blocked, use:
1924 # Blocked URL = http://www.example.com/blocked
1926 To verify that a specific set of actions is applied to an URL, use:
1928 # Sticky Actions = +block{foo} +handle-as-empty-document -handle-as-image
1929 # URL = http://www.example.org/my-first-url
1931 The sticky actions will be checked for all URLs below it
1932 until the next sticky actions directive.
1934 To verify that requests for a URL get redirected, use:
1936 # Redirected URL = http://www.example.com/redirect-me
1937 # Redirect Destination = http://www.example.org/redirected
1939 To skip a test, add the following line:
1943 The difference between a skipped test and a removed one is that removing
1944 a test affects the numbers of the following tests, while a skipped test
1945 is still loaded and thus keeps the test numbers unchanged.
1947 Sometimes user modifications intentionally conflict with tests in the
1948 default configuration and thus cause test failures. Adding the Ignore
1949 directive to the failing tests works but is inconvenient as the directive
1950 is likely to get lost with the next update.
1952 Overwrite conditions are an alternative and can be added in any action
1953 file as long as the come after the test that is expected to fail.
1954 They cause all previous tests that match the condition to be skipped.
1956 It is recommended to put the overwrite condition below the custom Privoxy
1957 section that causes the expected test failure and before the custom test
1958 that verifies that tests the now expected behaviour. Example:
1960 # The following section is expected to overwrite a section in
1961 # default.action, whose effect is being tested. Thus also disable
1962 # the test that is now expected to fail and add a new one.
1964 {+block{Facebook makes Firefox even more unstable. Do not want.}}
1965 # Overwrite condition = http://apps.facebook.com/onthefarm/track.php?creative=&cat=friendvisit&subcat=weeds&key=a789a971dc687bee4c20c044834fabdd&next=index.php%3Fref%3Dnotif%26visitId%3D898835505
1966 # Blocked URL = http://apps.facebook.com/
1971 All tests have test levels to let the user
1972 control which ones to execute (see I<OPTIONS> below).
1973 Test levels are either set with the B<Level> directive,
1974 or implicitly through the test type.
1976 Redirect tests default to level 108, block tests to level 7,
1977 fetch tests to level 6, "Sticky Actions" tests default to
1978 level 5, tests for trusted CGI requests to level 3 and
1979 client-header-action tests to level 1.
1981 The current redirect test level is above the default
1982 max-level value as failed tests will result in outgoing
1983 connections. Use the B<--max-level> option to run them
1986 The "Default level offset" directive can be used to change
1987 the default level by a given value. This directive affects
1988 all tests located after it until the end of the file or a another
1989 "Default level offset" directive is reached. The purpose of this
1990 directive is to make it more convenient to skip similar tests in
1991 a given file without having to remove or disable the tests completely.
1995 B<--debug bitmask> Add the bitmask provided as integer
1996 to the debug settings.
1998 B<--forks forks> Number of forks to start before executing
1999 the regression tests. This is mainly useful for stress-testing.
2001 B<--fuzzer-address> Listening address used when executing
2002 the regression tests. Useful to make sure that the requests
2003 to load the regression tests don't fail due to fuzzing.
2005 B<--fuzzer-feeding> Ignore some errors that would otherwise
2006 cause Privoxy-Regression-Test to abort the test because
2007 they shouldn't happen in normal operation. This option is
2008 intended to be used if Privoxy-Regression-Test is only
2009 used to feed a fuzzer in which case there's a high chance
2010 that Privoxy gets an invalid request and returns an error
2013 B<--help> Shows available command line options.
2015 B<--header-fuzzing> Modifies linear white space in
2016 headers in a way that should not affect the test result.
2018 B<--level level> Only execute tests with the specified B<level>.
2020 B<--local-test-file test-file> Do not get the tests
2021 through Privoxy's web interface, but use a single local
2022 file. Not recommended for testing Privoxy, but can be useful
2023 to "misappropriate" Privoxy-Regression-Test to test other
2024 stuff, like webserver configurations.
2026 B<--loop count> Loop through the regression tests B<count> times.
2027 Useful to feed a fuzzer, or when doing stress tests with
2028 several Privoxy-Regression-Test instances running at the same
2031 B<--max-level max-level> Only execute tests with a B<level>
2032 below or equal to the numerical B<max-level>.
2034 B<--max-time max-time> Give Privoxy B<max-time> seconds
2035 to return data. Increasing the default may make sense when
2036 Privoxy is run through Valgrind, decreasing the default may
2037 make sense when Privoxy-Regression-Test is used to feed
2040 B<--min-level min-level> Only execute tests with a B<level>
2041 above or equal to the numerical B<min-level>.
2043 B<--privoxy-address proxy-address> Privoxy's listening address.
2044 If it's not set, the value of the environment variable http_proxy
2045 will be used. B<proxy-address> has to be specified in http_proxy
2048 B<--privoxy-cgi-prefix privoxy-cgi-prefix> The prefix to use when
2049 building URLs that are supposed to reach Privoxy's CGI interface.
2050 If it's not set, B<http://p.p/> is used, which is supposed to work
2051 with the default Privoxy configuration.
2052 If Privoxy has been built with B<FEATURE_HTTPS_INSPECTION> enabled,
2053 and if https inspection is activated with the B<+https-inspection>
2054 action, this option can be used with
2055 B<https://p.p/> provided the system running Privoxy-Regression-Test
2056 has been configured to trust the certificate used by Privoxy.
2057 Note that there are currently two tests in the official
2058 B<regression-tests.action> file that are expected to fail when
2059 using a B<privoxy-cgi-prefix> with B<https://> and aren't automatically
2062 B<--retries retries> Retry B<retries> times.
2064 B<--test-number test-number> Only run the test with the specified
2067 B<--show-skipped-tests> Log skipped tests even if verbose mode is off.
2069 B<--shuffle-tests> Shuffle test sections and their tests before
2070 executing them. When combined with B<--forks>, this can increase
2071 the chances of detecting race conditions. Of course some problems
2072 are easier to detect without this option.
2074 B<--sleep-time seconds> Wait B<seconds> between tests. Useful when
2075 debugging issues with systems that don't log with millisecond precision.
2077 B<--verbose> Log successful tests as well. By default only
2078 the failures are logged.
2080 B<--version> Print version and exit.
2082 The second dash is optional, options can be shortened,
2083 as long as there are no ambiguities.
2085 =head1 PRIVOXY CONFIGURATION
2087 Privoxy-Regression-Test is shipped with B<regression-tests.action>
2088 which aims to test all official client-header modifying actions
2089 and can be used to verify that the templates and the user manual
2090 files are installed correctly.
2092 To use it, it has to be copied in Privoxy's configuration
2093 directory, and afterwards referenced in Privoxy's configuration
2096 actionsfile regression-tests.action
2098 In general, its tests are supposed to work without changing
2099 any other action files, unless you already added lots of
2100 taggers yourself. If you are using taggers that cause problems,
2101 you might have to temporary disable them for Privoxy's CGI pages.
2103 Some of the regression tests rely on Privoxy features that
2104 may be disabled in your configuration. Tests with a level below
2105 7 are supposed to work with all Privoxy configurations (provided
2106 you didn't build with FEATURE_GRACEFUL_TERMINATION).
2108 Tests with level 9 require Privoxy to deliver the User Manual,
2109 tests with level 12 require the CGI editor to be enabled.
2113 Expect the configuration file syntax to change with future releases.
2117 As Privoxy's B<show-request> page only shows client headers,
2118 Privoxy-Regression-Test can't use it to test Privoxy actions
2119 that modify server headers.
2121 As Privoxy-Regression-Test relies on Privoxy's tag feature to
2122 control the actions to test, it currently only works with
2123 Privoxy 3.0.7 or later.
2125 At the moment Privoxy-Regression-Test fetches Privoxy's
2126 configuration page through I<curl>(1), therefore you have to
2127 have I<curl> installed, otherwise you won't be able to run
2128 Privoxy-Regression-Test in a meaningful way.
