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?

1836 Privoxy-Regression-Test is supposed to one day become
1837 a regression test suite for Privoxy. It's not quite there
1838 yet, however, and can currently only test header actions,
1839 check the returned status code for requests to arbitrary
1840 URLs and verify which actions are applied to them.
1842 Client header actions are tested by requesting
1843 B<http://p.p/show-request> and checking whether
1844 or not Privoxy modified the original request as expected.
1846 The original request contains both the header the action-to-be-tested
1847 acts upon and an additional tagger-triggering header that enables
1850 Applied actions are checked through B<http://p.p/show-url-info>.
1852 =head1 CONFIGURATION FILE SYNTAX
1854 Privoxy-Regression-Test's configuration is embedded in
1855 Privoxy action files and loaded through Privoxy's web interface.
1857 It makes testing a Privoxy version running on a remote system easier
1858 and should prevent you from updating your tests without updating Privoxy's
1859 configuration accordingly.
1861 A client-header-action test section looks like this:
1863 # Set Header = Referer: http://www.example.org.zwiebelsuppe.exit/
1864 # Expect Header = Referer: http://www.example.org/
1865 {+client-header-filter{hide-tor-exit-notation} -hide-referer}
1866 TAG:^client-header-filter\{hide-tor-exit-notation\}$
1868 The example above causes Privoxy-Regression-Test to set
1869 the header B<Referer: http://www.example.org.zwiebelsuppe.exit/>
1870 and to expect it to be modified to
1871 B<Referer: http://www.example.org/>.
1873 When testing this section, Privoxy-Regression-Test will set the header
1874 B<X-Privoxy-Control: client-header-filter{hide-tor-exit-notation}>
1875 causing the B<privoxy-control> tagger to create the tag
1876 B<client-header-filter{hide-tor-exit-notation}> which will finally
1877 cause Privoxy to enable the action section.
1879 Note that the actions itself are only used by Privoxy,
1880 Privoxy-Regression-Test ignores them and will be happy
1881 as long as the expectations are satisfied.
1883 A fetch test looks like this:
1885 # Fetch Test = http://p.p/user-manual
1886 # Expect Status Code = 302
1888 It tells Privoxy-Regression-Test to request B<http://p.p/user-manual>
1889 and to expect a response with the HTTP status code B<302>. Obviously that's
1890 not a very thorough test and mainly useful to get some code coverage
1891 for Valgrind or to verify that the templates are installed correctly.
1893 If you want to test CGI pages that require a trusted
1894 referer, you can use:
1896 # Trusted CGI Request = http://p.p/edit-actions
1898 It works like ordinary fetch tests, but sets the referer
1899 header to a trusted value.
1901 If no explicit status code expectation is set, B<200> is used.
1903 To verify that a URL is blocked, use:
1905 # Blocked URL = http://www.example.com/blocked
1907 To verify that a specific set of actions is applied to an URL, use:
1909 # Sticky Actions = +block{foo} +handle-as-empty-document -handle-as-image
1910 # URL = http://www.example.org/my-first-url
1912 The sticky actions will be checked for all URLs below it
1913 until the next sticky actions directive.
1915 To verify that requests for a URL get redirected, use:
1917 # Redirected URL = http://www.example.com/redirect-me
1918 # Redirect Destination = http://www.example.org/redirected
1920 To skip a test, add the following line:
1924 The difference between a skipped test and a removed one is that removing
1925 a test affects the numbers of the following tests, while a skipped test
1926 is still loaded and thus keeps the test numbers unchanged.
1928 Sometimes user modifications intentionally conflict with tests in the
1929 default configuration and thus cause test failures. Adding the Ignore
1930 directive to the failing tests works but is inconvenient as the directive
1931 is likely to get lost with the next update.
1933 Overwrite conditions are an alternative and can be added in any action
1934 file as long as the come after the test that is expected to fail.
1935 They cause all previous tests that match the condition to be skipped.
1937 It is recommended to put the overwrite condition below the custom Privoxy
1938 section that causes the expected test failure and before the custom test
1939 that verifies that tests the now expected behaviour. Example:
1941 # The following section is expected to overwrite a section in
1942 # default.action, whose effect is being tested. Thus also disable
1943 # the test that is now expected to fail and add a new one.
1945 {+block{Facebook makes Firefox even more unstable. Do not want.}}
1946 # Overwrite condition = http://apps.facebook.com/onthefarm/track.php?creative=&cat=friendvisit&subcat=weeds&key=a789a971dc687bee4c20c044834fabdd&next=index.php%3Fref%3Dnotif%26visitId%3D898835505
1947 # Blocked URL = http://apps.facebook.com/
1952 All tests have test levels to let the user
1953 control which ones to execute (see I<OPTIONS> below).
1954 Test levels are either set with the B<Level> directive,
1955 or implicitly through the test type.
1957 Redirect tests default to level 108, block tests to level 7,
1958 fetch tests to level 6, "Sticky Actions" tests default to
1959 level 5, tests for trusted CGI requests to level 3 and
1960 client-header-action tests to level 1.
1962 The current redirect test level is above the default
1963 max-level value as failed tests will result in outgoing
1964 connections. Use the B<--max-level> option to run them
1967 The "Default level offset" directive can be used to change
1968 the default level by a given value. This directive affects
1969 all tests located after it until the end of the file or a another
1970 "Default level offset" directive is reached. The purpose of this
1971 directive is to make it more convenient to skip similar tests in
1972 a given file without having to remove or disable the tests completely.
1976 B<--debug bitmask> Add the bitmask provided as integer
1977 to the debug settings.
1979 B<--forks forks> Number of forks to start before executing
1980 the regression tests. This is mainly useful for stress-testing.
1982 B<--fuzzer-address> Listening address used when executing
1983 the regression tests. Useful to make sure that the requests
1984 to load the regression tests don't fail due to fuzzing.
1986 B<--fuzzer-feeding> Ignore some errors that would otherwise
1987 cause Privoxy-Regression-Test to abort the test because
1988 they shouldn't happen in normal operation. This option is
1989 intended to be used if Privoxy-Regression-Test is only
1990 used to feed a fuzzer in which case there's a high chance
1991 that Privoxy gets an invalid request and returns an error
1994 B<--help> Shows available command line options.
1996 B<--header-fuzzing> Modifies linear white space in
1997 headers in a way that should not affect the test result.
1999 B<--level level> Only execute tests with the specified B<level>.
2001 B<--local-test-file test-file> Do not get the tests
2002 through Privoxy's web interface, but use a single local
2003 file. Not recommended for testing Privoxy, but can be useful
2004 to "misappropriate" Privoxy-Regression-Test to test other
2005 stuff, like webserver configurations.
2007 B<--loop count> Loop through the regression tests B<count> times.
2008 Useful to feed a fuzzer, or when doing stress tests with
2009 several Privoxy-Regression-Test instances running at the same
2012 B<--max-level max-level> Only execute tests with a B<level>
2013 below or equal to the numerical B<max-level>.
2015 B<--max-time max-time> Give Privoxy B<max-time> seconds
2016 to return data. Increasing the default may make sense when
2017 Privoxy is run through Valgrind, decreasing the default may
2018 make sense when Privoxy-Regression-Test is used to feed
2021 B<--min-level min-level> Only execute tests with a B<level>
2022 above or equal to the numerical B<min-level>.
2024 B<--privoxy-address proxy-address> Privoxy's listening address.
2025 If it's not set, the value of the environment variable http_proxy
2026 will be used. B<proxy-address> has to be specified in http_proxy
2029 B<--retries retries> Retry B<retries> times.
2031 B<--test-number test-number> Only run the test with the specified
2034 B<--show-skipped-tests> Log skipped tests even if verbose mode is off.
2036 B<--shuffle-tests> Shuffle test sections and their tests before
2037 executing them. When combined with B<--forks>, this can increase
2038 the chances of detecting race conditions. Of course some problems
2039 are easier to detect without this option.
2041 B<--sleep-time seconds> Wait B<seconds> between tests. Useful when
2042 debugging issues with systems that don't log with millisecond precision.
2044 B<--verbose> Log successful tests as well. By default only
2045 the failures are logged.
2047 B<--version> Print version and exit.
2049 The second dash is optional, options can be shortened,
2050 as long as there are no ambiguities.
2052 =head1 PRIVOXY CONFIGURATION
2054 Privoxy-Regression-Test is shipped with B<regression-tests.action>
2055 which aims to test all official client-header modifying actions
2056 and can be used to verify that the templates and the user manual
2057 files are installed correctly.
2059 To use it, it has to be copied in Privoxy's configuration
2060 directory, and afterwards referenced in Privoxy's configuration
2063 actionsfile regression-tests.action
2065 In general, its tests are supposed to work without changing
2066 any other action files, unless you already added lots of
2067 taggers yourself. If you are using taggers that cause problems,
2068 you might have to temporary disable them for Privoxy's CGI pages.
2070 Some of the regression tests rely on Privoxy features that
2071 may be disabled in your configuration. Tests with a level below
2072 7 are supposed to work with all Privoxy configurations (provided
2073 you didn't build with FEATURE_GRACEFUL_TERMINATION).
2075 Tests with level 9 require Privoxy to deliver the User Manual,
2076 tests with level 12 require the CGI editor to be enabled.
2080 Expect the configuration file syntax to change with future releases.
2084 As Privoxy's B<show-request> page only shows client headers,
2085 Privoxy-Regression-Test can't use it to test Privoxy actions
2086 that modify server headers.
2088 As Privoxy-Regression-Test relies on Privoxy's tag feature to
2089 control the actions to test, it currently only works with
2090 Privoxy 3.0.7 or later.
2092 At the moment Privoxy-Regression-Test fetches Privoxy's
2093 configuration page through I<curl>(1), therefore you have to
2094 have I<curl> installed, otherwise you won't be able to run
2095 Privoxy-Regression-Test in a meaningful way.
