;;;; Commentary:
;;;
;;; This script provides a Guile test driver using the SRFI-64 Scheme API for
;;; test suites. SRFI-64 is distributed with Guile since version 2.0.9.
;;;
;;; To use it, you have to manually copy this file in the ‘build-aux’
;;; directory of your package, then adapt the following snippets to your
;;; actual needs:
;;;
;;; configure.ac:
;;; AC_CONFIG_AUX_DIR([build-aux])
;;; AC_REQUIRE_AUX_FILE([test-driver.scm])
;;; AC_PATH_PROG([GUILE], [guile])
;;;
;;; Makefile.am
;;; TEST_LOG_DRIVER = $(GUILE) $(top_srcdir)/build-aux/test-driver.scm
;;; AM_TESTS_ENVIRONMENT = env GUILE_AUTO_COMPILE='0'
;;; TESTS = foo.test
;;; EXTRA_DIST = $(TESTS)
;;;
;;; foo.test
;;; (use-modules (srfi srfi-64))
;;; (test-begin "foo")
;;; (test-assert "assertion example" #t)
;;; (test-end "foo")
;;;
;;; See <https://srfi.schemers.org/srfi-64/srfi-64.html> for general
;;; information about SRFI-64 usage.
