   2 # This script generates a list of testsuites that should be run as part of
   3 # the Samba 4 test suite.
   4
   5 # The output of this script is parsed by selftest.pl, which then decides
   6 # which of the tests to actually run. It will, for example, skip all tests
   7 # listed in selftest/skip or only run a subset during "make quicktest".
   8
   9 # The idea is that this script outputs all of the tests of Samba 4, not
  10 # just those that are known to pass, and list those that should be skipped
  11 # or are known to fail in selftest/skip or selftest/knownfail. This makes it
  12 # very easy to see what functionality is still missing in Samba 4 and makes
  13 # it possible to run the testsuite against other servers, such as Samba 3 or
  14 # Windows that have a different set of features.
  15
  16 # The syntax for a testsuite is "-- TEST --" on a single line, followed
  17 # by the name of the test, the environment it needs and the command to run, all
  18 # three separated by newlines. All other lines in the output are considered
  19 # comments.
