   6 # This is the controlling script for the "new" test suite for Exim. It should #
   7 # be possible to export this suite for running on a wide variety of hosts, in #
   8 # contrast to the old suite, which was very dependent on the environment of   #
   9 # Philip Hazel's desktop computer. This implementation inspects the version   #
  10 # of Exim that it finds, and tests only those features that are included. The #
  11 # surrounding environment is also tested to discover what is available. See   #
  12 # the README file for details of how it all works.                            #
  13 #                                                                             #
  14 # Implementation started: 03 August 2005 by Philip Hazel                      #
  15 # Placed in the Exim CVS: 06 February 2006                                    #

4147
4148 =over
4149

4151
4152 Do not stop for user interaction or on errors. (default: off)
4153
4154 =item B<--debug>
4155
4156 This option enables the output of debug information when running the
4157 various test commands. (default: off)
4158
4159 =item B<--diff>
4160
4161 Use C<diff -u> for comparing the expected output with the produced
4162 output. (default: use a built-in routine)
4163
4164 =item B<--flavor>|B<--flavour> I<flavour>
4165
4166 Override the expected results for results for a specific (OS) flavour.
4167 (default: unused)
4168
4169 =item B<--[no]ipv4>
4170
4171 Skip IPv4 related setup and tests (default: use ipv4)

4175 Skip IPv6 related setup and tests (default: use ipv6)
4176
4177 =item B<--keep>
4178
4179 Keep the various output files produced during a test run. (default: don't keep)
4180
4181 =item B<--range> I<n0> I<n1>
4182
4183 Run tests between (including) I<n0> and I<n1>. A "+" may be used to specify the "last
4184 test available".
4185
4186 =item B<--slow>
4187
4188 Insert some delays to compensate for a slow host system. (default: off)
4189
4190 =item B<--test> I<n>
4191
4192 Run the specified test. This option may used multiple times.
4193
4194 =item B<--update>
4195
4196 Automatically update the recorded (expected) data on mismatch. (default: off)
4197
4198 =item B<--valgrind>
