From f66e567e6e91901615fef15cd822054816aee044 Mon Sep 17 00:00:00 2001 From: ngie Date: Sat, 27 May 2017 23:26:10 +0000 Subject: MFC r316099: lib/libkvm: start adding basic tests for kvm(3) - kvm_close: add a testcase to verify support for errno = EINVAL / -1 (see D10065) when kd == NULL is provided to the libcall. - kvm_geterr: -- Add a negative testcase for kd == NULL returning "" (see D10022). -- Add two positive testcases: --- test the error case using kvm_write on a O_RDONLY descriptor. --- test the "no error" case using kvm_read(3) and kvm_nlist(3) as helper routines and by injecting a bogus error message via _kvm_err (an internal API) _kvm_err was used as there isn't a formalized way to clear the error output, and because kvm_nlist always returns ENOENT with the NULL terminator today. - kvm_open, kvm_open2: -- Add some basic negative tests for kvm_open(3) and kvm_open2(3). Testing positive cases with a specific `corefile`/`execfile`/`resolver` requires more work and would require user intervention today in order to reliably test this out. MFC note: lib/libkvm/kvm_open2_test is not compiled/tested because ^/stable/10 lacks the kvm_open2(3) libcall. --- lib/libkvm/tests/kvm_test_common.c | 49 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 lib/libkvm/tests/kvm_test_common.c (limited to 'lib/libkvm/tests/kvm_test_common.c') diff --git a/lib/libkvm/tests/kvm_test_common.c b/lib/libkvm/tests/kvm_test_common.c new file mode 100644 index 0000000..ae9f081 --- /dev/null +++ b/lib/libkvm/tests/kvm_test_common.c @@ -0,0 +1,49 @@ +/*- + * Copyright (c) 2017 Ngie Cooper + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
