1829 Privoxy-Regression-Test is supposed to one day become
1830 a regression test suite for Privoxy. It's not quite there
1831 yet, however, and can currently only test header actions,
1832 check the returned status code for requests to arbitrary
1833 URLs and verify which actions are applied to them.
1835 Client header actions are tested by requesting
1836 B<http://p.p/show-request> and checking whether
1837 or not Privoxy modified the original request as expected.
1839 The original request contains both the header the action-to-be-tested
1840 acts upon and an additional tagger-triggering header that enables
1843 Applied actions are checked through B<http://p.p/show-url-info>.
1845 =head1 CONFIGURATION FILE SYNTAX
1847 Privoxy-Regression-Test's configuration is embedded in
1848 Privoxy action files and loaded through Privoxy's web interface.
1850 It makes testing a Privoxy version running on a remote system easier
1851 and should prevent you from updating your tests without updating Privoxy's
1852 configuration accordingly.
1854 A client-header-action test section looks like this:
1856 # Set Header = Referer: http://www.example.org.zwiebelsuppe.exit/
1857 # Expect Header = Referer: http://www.example.org/
1858 {+client-header-filter{hide-tor-exit-notation} -hide-referer}
1859 TAG:^client-header-filter\{hide-tor-exit-notation\}$
1861 The example above causes Privoxy-Regression-Test to set
1862 the header B<Referer: http://www.example.org.zwiebelsuppe.exit/>
1863 and to expect it to be modified to
1864 B<Referer: http://www.example.org/>.
1866 When testing this section, Privoxy-Regression-Test will set the header
1867 B<X-Privoxy-Control: client-header-filter{hide-tor-exit-notation}>
1868 causing the B<privoxy-control> tagger to create the tag
1869 B<client-header-filter{hide-tor-exit-notation}> which will finally
1870 cause Privoxy to enable the action section.
1872 Note that the actions itself are only used by Privoxy,
1873 Privoxy-Regression-Test ignores them and will be happy
1874 as long as the expectations are satisfied.
1876 A fetch test looks like this:
1878 # Fetch Test = http://p.p/user-manual
1879 # Expect Status Code = 302
1881 It tells Privoxy-Regression-Test to request B<http://p.p/user-manual>
1882 and to expect a response with the HTTP status code B<302>. Obviously that's
1883 not a very thorough test and mainly useful to get some code coverage
1884 for Valgrind or to verify that the templates are installed correctly.
1886 If you want to test CGI pages that require a trusted
1887 referer, you can use:
1889 # Trusted CGI Request = http://p.p/edit-actions
1891 It works like ordinary fetch tests, but sets the referer
1892 header to a trusted value.
1894 If no explicit status code expectation is set, B<200> is used.
1896 To verify that a URL is blocked, use:
1898 # Blocked URL = http://www.example.com/blocked
1900 To verify that a specific set of actions is applied to an URL, use:
1902 # Sticky Actions = +block{foo} +handle-as-empty-document -handle-as-image
1903 # URL = http://www.example.org/my-first-url
1905 The sticky actions will be checked for all URLs below it
1906 until the next sticky actions directive.
1908 To verify that requests for a URL get redirected, use:
1910 # Redirected URL = http://www.example.com/redirect-me
1911 # Redirect Destination = http://www.example.org/redirected
1913 To skip a test, add the following line:
1917 The difference between a skipped test and a removed one is that removing
1918 a test affects the numbers of the following tests, while a skipped test
1919 is still loaded and thus keeps the test numbers unchanged.
1921 Sometimes user modifications intentionally conflict with tests in the
1922 default configuration and thus cause test failures. Adding the Ignore
1923 directive to the failing tests works but is inconvenient as the directive
1924 is likely to get lost with the next update.
1926 Overwrite conditions are an alternative and can be added in any action
1927 file as long as the come after the test that is expected to fail.
1928 They causes all previous tests a matching the condition to be skipped.
1930 It is recommended to put the overwrite condition below the custom Privoxy
1931 section that causes the expected test failure and before the custom test
1932 that verifies that tests the now expected behaviour. Example:
1934 # The following section is expected to overwrite a section in
1935 # default.action, whose effect is tested. Thus also disable the
1936 # test that is now expected to fail and add a new one.
1938 {+block{Facebook makes Firefox even more unstable. Do not want.}}
1939 # Overwrite condition = http://apps.facebook.com/onthefarm/track.php?creative=&cat=friendvisit&subcat=weeds&key=a789a971dc687bee4c20c044834fabdd&next=index.php%3Fref%3Dnotif%26visitId%3D898835505
1940 # Blocked URL = http://apps.facebook.com/
1945 All tests have test levels to let the user
1946 control which ones to execute (see I<OPTIONS> below).
1947 Test levels are either set with the B<Level> directive,
1948 or implicitly through the test type.
1950 Redirect tests default to level 108, block tests to level 7,
1951 fetch tests to level 6, "Sticky Actions" tests default to
1952 level 5, tests for trusted CGI requests to level 3 and
1953 client-header-action tests to level 1.
1955 The current redirect test level is above the default
1956 max-level value as failed tests will result in outgoing
1957 connections. Use the B<--max-level> option to run them
1962 B<--debug bitmask> Add the bitmask provided as integer
1963 to the debug settings.
1965 B<--forks forks> Number of forks to start before executing
1966 the regression tests. This is mainly useful for stress-testing.
1968 B<--fuzzer-address> Listening address used when executing
1969 the regression tests. Useful to make sure that the requests
1970 to load the regression tests don't fail due to fuzzing.
1972 B<--fuzzer-feeding> Ignore some errors that would otherwise
1973 cause Privoxy-Regression-Test to abort the test because
1974 they shouldn't happen in normal operation. This option is
1975 intended to be used if Privoxy-Regression-Test is only
1976 used to feed a fuzzer in which case there's a high chance
1977 that Privoxy gets an invalid request and returns an error
1980 B<--help> Shows available command line options.
1982 B<--header-fuzzing> Modifies linear white space in
1983 headers in a way that should not affect the test result.
1985 B<--level level> Only execute tests with the specified B<level>.
1987 B<--local-test-file test-file> Do not get the tests
1988 through Privoxy's web interface, but use a single local
1989 file. Not recommended for testing Privoxy, but can be useful
1990 to "misappropriate" Privoxy-Regression-Test to test other
1991 stuff, like webserver configurations.
1993 B<--loop count> Loop through the regression tests B<count> times.
1994 Useful to feed a fuzzer, or when doing stress tests with
1995 several Privoxy-Regression-Test instances running at the same
1998 B<--max-level max-level> Only execute tests with a B<level>
1999 below or equal to the numerical B<max-level>.
2001 B<--max-time max-time> Give Privoxy B<max-time> seconds
2002 to return data. Increasing the default may make sense when
2003 Privoxy is run through Valgrind, decreasing the default may
2004 make sense when Privoxy-Regression-Test is used to feed
2007 B<--min-level min-level> Only execute tests with a B<level>
2008 above or equal to the numerical B<min-level>.
2010 B<--privoxy-address proxy-address> Privoxy's listening address.
2011 If it's not set, the value of the environment variable http_proxy
2012 will be used. B<proxy-address> has to be specified in http_proxy
2015 B<--retries retries> Retry B<retries> times.
2017 B<--test-number test-number> Only run the test with the specified
2020 B<--show-skipped-tests> Log skipped tests even if verbose mode is off.
2022 B<--shuffle-tests> Shuffle test sections and their tests before
2023 executing them. When combined with B<--forks>, this can increase
2024 the chances of detecting race conditions. Of course some problems
2025 are easier to detect without this option.
2027 B<--sleep-time seconds> Wait B<seconds> between tests. Useful when
2028 debugging issues with systems that don't log with millisecond precision.
2030 B<--verbose> Log successful tests as well. By default only
2031 the failures are logged.
2033 B<--version> Print version and exit.
2035 The second dash is optional, options can be shortened,
2036 as long as there are no ambiguities.
2038 =head1 PRIVOXY CONFIGURATION
2040 Privoxy-Regression-Test is shipped with B<regression-tests.action>
2041 which aims to test all official client-header modifying actions
2042 and can be used to verify that the templates and the user manual
2043 files are installed correctly.
2045 To use it, it has to be copied in Privoxy's configuration
2046 directory, and afterwards referenced in Privoxy's configuration
2049 actionsfile regression-tests.action
2051 In general, its tests are supposed to work without changing
2052 any other action files, unless you already added lots of
2053 taggers yourself. If you are using taggers that cause problems,
2054 you might have to temporary disable them for Privoxy's CGI pages.
2056 Some of the regression tests rely on Privoxy features that
2057 may be disabled in your configuration. Tests with a level below
2058 7 are supposed to work with all Privoxy configurations (provided
2059 you didn't build with FEATURE_GRACEFUL_TERMINATION).
2061 Tests with level 9 require Privoxy to deliver the User Manual,
2062 tests with level 12 require the CGI editor to be enabled.
2066 Expect the configuration file syntax to change with future releases.
2070 As Privoxy's B<show-request> page only shows client headers,
2071 Privoxy-Regression-Test can't use it to test Privoxy actions
2072 that modify server headers.
2074 As Privoxy-Regression-Test relies on Privoxy's tag feature to
2075 control the actions to test, it currently only works with
2076 Privoxy 3.0.7 or later.
2078 At the moment Privoxy-Regression-Test fetches Privoxy's
2079 configuration page through I<curl>(1), therefore you have to
2080 have I<curl> installed, otherwise you won't be able to run
2081 Privoxy-Regression-Test in a meaningful way.
