33.4. TAP Tests
  Various tests, particularly the client program tests
    under
  
   src/bin
  
  , use the Perl TAP tools and are run
    using the Perl testing program
  
   prove
  
  .  You can pass
    command-line options to
  
   prove
  
  by setting
    the
  
   make
  
  variable
  
   PROVE_FLAGS
  
  , for example:
 
make -C src/bin check PROVE_FLAGS='--timer'
  See the manual page of
  
   prove
  
  for more information.
 
  The
  
   make
  
  variable
  
   PROVE_TESTS
  
  can be used to define a whitespace-separated list of paths relative
    to the
  
   Makefile
  
  invoking
  
   prove
  
  to run the specified subset of tests instead of the default
  
   t/*.pl
  
  .  For example:
 
make check PROVE_TESTS='t/001_test1.pl t/003_test3.pl'
  The TAP tests require the Perl module
  
   IPC::Run
  
  .
    This module is available from CPAN or an operating system package.
