# Tests
# We add a separate "memcheck" target which runs valgrind on all tests in
# MEMTESTS. Note that we fail if _any_ leak is detected by valgrind. Thus, you
# need to have valgrind installed and libcheck running properly (without leaks)
# to make memcheck succeed.
# A separate memcheck-verify actually runs a faulty test and verifies the
# valgrind tests work properly.
