  23 #       Mnemonic:       unit_test.ksh
  24 #       Abstract:       Execute unit test(s) in the directory and produce a more
  25 #                               meaningful summary than gcov gives by default (exclude
  26 #                               coverage  on the unit test functions).
  27 #
  28 #                               Test files must be named *_test.c, or must explicitly be
  29 #                               supplied on the command line. Functions in the test
  30 #                               files will not be reported on provided that they have
  31 #                               their prototype (all on the SAME line) as:
  32 #                                       static type name() {
  33 #
  34 #                               Functions with coverage less than 80% will be reported as
  35 #                               [LOW] in the output.  A file is considered to pass if the
  36 #                               overall execution percentage for the file is >= 80% regardless
  37 #                               of the number of functions that reported low.
  38 #
  39 #                               Test programmes are built prior to execution. Plan-9 mk is
  40 #                               the preferred builder, but as it's not widly adopted (sigh)
  41 #                               make is assumed and -M will shift to Plan-9. Use -C xxx to
  42 #                               invoke a customised builder.
  43 #
  44 #                               For a module which does not pass, we will attempt to boost
  45 #                               the coverage by discounting the unexecuted lines which are
  46 #                               inside of if() statements that are checking return from
  47 #                               (m)alloc() calls or are checking for nil pointers as these
  48 #                               cases are likely impossible to drive. When discount testing
  49 #                               is done both the failure message from the original analysis
  50 #                               and a pass/fail message from the discount test are listed,
  51 #                               but only the result of the discount test is taken into
  52 #                               consideration with regard to overall success.
  53 #
  54 #                               Overall Pass/Fail
  55 #                               By default the overall state is based only on the success
  56 #                               or failure of the unit tests and NOT on the perceived
  57 #                               state of coverage.  If the -s (strict) option is given, then
  58 #                               overall state will be failure if code coverage expectations
  59 #                               are not met.
