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

Question

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".

Answer 1

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
!#
