   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 For legacy reasons the options are not case sensitive.
4148
4149 =over
4150

4152
4153 Do not stop for user interaction or on errors. (default: off)
4154
4155 =item B<--debug>
4156
4157 This option enables the output of debug information when running the
4158 various test commands. (default: off)
4159
4160 =item B<--diff>
4161
4162 Use C<diff -u> for comparing the expected output with the produced
4163 output. (default: use a built-in routine)
4164
4165 =item B<--flavor>|B<--flavour> I<flavour>
4166
4167 Override the expected results for results for a specific (OS) flavour.
4168 (default: unused)
4169
4170 =item B<--[no]ipv4>
4171
4172 Skip IPv4 related setup and tests (default: use ipv4)
4173
4174 =item B<--[no]ipv6>
4175
4176 Skip IPv6 related setup and tests (default: use ipv6)
4177
4178 =item B<--keep>
4179
4180 Keep the various output files produced during a test run. (default: don't keep)
4181
4182 =item B<--range> I<n0> I<n1>
4183
4184 Run tests between (including) I<n0> and I<n1>. A "+" may be used to specify the "last
4185 test available".
4186
4187 =item B<--slow>
4188
4189 Insert some delays to compensate for a slow host system. (default: off)
4190
4191 =item B<--test> I<n>
4192
4193 Run the specified test. This option may used multiple times.
4194
4195 =item B<--update>
4196
4197 Automatically update the recorded (expected) data on mismatch. (default: off)
4198
4199 =item B<--valgrind>
4200
4201 Start Exim wrapped by I<valgrind>. (default: don't use valgrind)
