It would be nice if it were possible to run tests in parallel using
automake. Waiting for tests to complete on a 4-way box while they are run
on a single CPU is annoying. As most 'make' implementations already
support running in parallel (-j), automake could just utilize this
functionality to runt tests in parallel.
The following demonstrates the concept, although it contains some gnu-make
specific syntax and leaves out lots of other automake stuff (e.g. subdirs).
AM_CHECK_RESULTS = $(TESTS:%=am_%.out)
check:
@rm $(AM_CHECK_RESULTS)
$(MAKE) check-new
check-new: $(AM_CHECK_RESULTS)
@total=0; failed=0; \
for file in $(AM_CHECK_RESULTS); do \
total=`expr $$total + 1`; \
if test -f $$file; then \
val=`cat $$file`; \
failed=`expr $$failed + $$val`; \
rm $$file; \
else \
failed=`expr $$failed + 1`; \
fi ; \
done; \
echo "*****************************************"; \
if test $$failed -gt 0; then \
echo "* $$failed of $$total tests failed"; \
else \
echo "* $$total tests passed"; \
fi; \
echo "*****************************************";
am_%.out: %
@if $(TESTS_ENVIRONMENT) $<; then \
echo "***** $< : SUCCESS"; \
echo "0" > $@ ; \
else \
echo "***** $< : FAILURE"; \
echo "1" > $@ ; \
fi
