   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                                    #

4084  runtest [exim-path] [options] [test0 [test1]]
4085
4086 =head1 DESCRIPTION
4087
4088 B<runtest> runs the Exim testsuite.

4092 For legacy reasons the options are not case sensitive.
4093
4094 =over
4095

4098 Do not stop for user interaction or on errors. (default: off)
4099
4100 =item B<--debug>
4101
4102 This option enables the output of debug information when running the
4103 various test commands. (default: off)
4104
4105 =item B<--diff>
4106
4107 Use C<diff -u> for comparing the expected output with the produced
4108 output. (default: use a built-in routine)
4109
4110 =item B<--flavor>|B<--flavour> I<flavour>
4111
4112 Override the expected results for results for a specific (OS) flavour.
4113 (default: unused)
4114
4115 =item B<--[no]ipv4>
4116
4117 Skip IPv4 related setup and tests (default: use ipv4)
4118
4119 =item B<--[no]ipv6>
4120
4121 Skip IPv6 related setup and tests (default: use ipv6)
4122
4123 =item B<--keep>
4124
4125 Keep the various output files produced during a test run. (default: don't keep)
4126
4127 =item B<--range> I<n0> I<n1>
4128
4129 Run tests between (including) I<n0> and I<n1>. A "+" may be used to specify the "last
4130 test available".
4131
4132 =item B<--slow>
4133
4134 Insert some delays to compensate for a slow host system. (default: off)
4135
4136 =item B<--test> I<n>
4137
4138 Run the specified test. This option may used multiple times.
4139
4140 =item B<--update>
4141
4142 Automatically update the recorded (expected) data on mismatch. (default: off)
4143
4144 =item B<--valgrind>
4145
4146 Start Exim wrapped by I<valgrind>. (default: don't use valgrind)
