# $NetBSD: Makefile,v 1.252 2020/12/19 16:00:17 rillig Exp $
#
# Unit tests for make(1)
#
# The main targets are:
#
# all:
#	run all the tests
# test:
#	run 'all', and compare to expected results
# accept:
#	move generated output to expected results
#
# Settable variables
#
# TEST_MAKE
#	The make program to be tested.
#
#
# Adding a test case
#
# Each feature should get its own set of tests in its own suitably
# named makefile (*.mk), with its own set of expected results (*.exp),
# and it should be added to the TESTS list.
#
# Any added files must also be added to src/distrib/sets/lists/tests/mi.
# To do that, just run "make sync-mi" in this directory.
#
# A few *.mk files are helper files for other tests (such as include-sub.mk)
# and are thus not added to TESTS.  Such files must be ignored in
# src/tests/usr.bin/make/t_make.sh.
#

# we use this below but we might be an older make
.MAKE.UID?= ${id -u:L:sh}

# Each test is in a sub-makefile.
# Keep the list sorted.
# Any test that is commented out must be ignored in
# src/tests/usr.bin/make/t_make.sh as well.
