# LOCAL UNIT TESTS
#
# We always run unit tests as part of the normal `make` invocation. you
# may override the $(TESTARGS) variable to do things such as enable the
# benchmarking feature. For example:
#
# TESTARGS = -b
#
# May be specified in your ~/.cosmo.mk file. You can also use this to
# enable things like function tracing. For example:
#
# TESTARGS = --ftrace
# .PLEDGE += prot_exec
#
# You could then run a command like:
#
# make -j8 o//test/libc/calls/openbsd_test.com.runs
#
# You need PROT_EXEC permission since ftrace morphs the binary. It's
# also worth mentioning that the pledge.com command can simulate what
# Landlock Make does:
#
# o//tool/build/pledge.com \
# -v. -p 'stdio rpath wpath cpath tty prot_exec' \
# o//test/libc/calls/openbsd_test.com \
# ----ftrace
#
# This is useful in the event a test binary should run by itself, but
# fails to run beneath Landlock Make. It's also useful sometimes to
# override the verbosity when running tests:
#
# make V=5 TESTARGS=-b o//test/libc/calls/openbsd_test.com.runs
#
# This way, if for some reason a test should fail but calls exit(0),
# then the stdout/stderr output, which would normally be suppressed,
# will actually be displayed.
