@@ -1624,6 +1916,41 @@ To verify that a specific set of actions is applied to an URL, use:
 The sticky actions will be checked for all URLs below it
 until the next sticky actions directive.
 
+To verify that requests for a URL get redirected, use:
+
+    # Redirected URL = http://www.example.com/redirect-me
+    # Redirect Destination = http://www.example.org/redirected
+
+To skip a test, add the following line:
+
+    # Ignore = Yes
+
+The difference between a skipped test and a removed one is that removing
+a test affects the numbers of the following tests, while a skipped test
+is still loaded and thus keeps the test numbers unchanged.
+
+Sometimes user modifications intentionally conflict with tests in the
+default configuration and thus cause test failures. Adding the Ignore
+directive to the failing tests works but is inconvenient as the directive
+is likely to get lost with the next update.
+
+Overwrite conditions are an alternative and can be added in any action
+file as long as the come after the test that is expected to fail.
+They cause all previous tests that match the condition to be skipped.
+
+It is recommended to put the overwrite condition below the custom Privoxy
+section that causes the expected test failure and before the custom test
+that verifies that tests the now expected behaviour. Example:
+
+    # The following section is expected to overwrite a section in
+    # default.action, whose effect is being tested. Thus also disable
+    # the test that is now expected to fail and add a new one.

+The current redirect test level is above the default

+The "Default level offset" directive can be used to change
