How to run TAP::Harness tests written in Guile?

The usual approach of

test:
    $(PERL) "-MExtUtils::Command::MM" "-e" "test_harness($(TEST_VERBOSE), '$(INCDIRS)')" $(TEST_FILES)

fails to run Guile scripts, because it passes to Guile the extra parameter "-w".

• One possible approach is to set up your project as follows.

  Your directory structure is as follows:

  ./project              Your project files
  ./project/t/*.t        Your unit test scripts
  ./project/t/scripts/*  Auxiliary scripts used by your unit tests

  Your ./project/Makefile contains the following:

  PERL = /usr/bin/perl
  TEST_LIBDIRS = ./lib
  RUN_GUILE_TESTS = ./t/scripts/RunGuileTests.pl
  TEST_FILES = ./t/*.t
  
  test:
      $(PERL) -I$(TEST_LIBDIRS) $(RUN_GUILE_TESTS) $(TEST_FILES)

  Your ./project/t/scripts/RunGuileTests.pl contents are:

  #!/usr/bin/perl -w
  # Run Guile tests - filenames are given as arguments to the script.
  
  use TAP::Harness;
  my @tests = @ARGV;
  my %args = (
      verbosity => 0,
      timer => 1,
      show_count => 1,
      exec => ['/usr/bin/guile', '-s'],
      );
  my $harness = TAP::Harness->new( \%args );
          $harness->runtests(@tests);
  
  # End of RunGuileTests.pl

  Your Guile test scripts should start with:

  #!/usr/bin/guile -s
  !#
  ; Description of your tests
