Re: [Libguestfs] [PATCH 6/7] tests: Add tests using a captive daemon process.

This allows us to test the daemon running as a host process, allowing us to meaningfully test it using valgrind. This commit only adds a single test that check that the daemon starts up, can be pinged, and exits. --- [...] .gitignore | 1 + Makefile.am | 1 + configure.ac | 2 + tests/daemon/Makefile.am | 36 +++++++++++ tests/daemon/captive-daemon.pm.in | 126 ++++++++++++++++++++++++++++++++++++++ tests/daemon/test-daemon-start.pl | 35 +++++++++++ 6 files changed, 201 insertions(+) create mode 100644 tests/daemon/Makefile.am create mode 100644 tests/daemon/captive-daemon.pm.in create mode 100755 tests/daemon/test-daemon-start.pl diff --git a/.gitignore b/.gitignore index 6f14915..6089122 100644 --- a/.gitignore +++ b/.gitignore @@ -528,6 +528,7 @@ Makefile.in /tests/data/lib-i586.so.xz /tests/data/test-grep.txt.gz /tests/data/test.iso +/tests/daemon/captive-daemon.pm /tests/disks/test-qemu-drive-libvirt.xml /tests/events/test-libvirt-auth-callbacks /tests/guests/blank-*.img diff --git a/Makefile.am b/Makefile.am index ad6d9d3..c545ea1 100644 --- a/Makefile.am +++ b/Makefile.am @@ -30,6 +30,7 @@ SUBDIRS += tests/data generator src examples po if ENABLE_DAEMON SUBDIRS += daemon +SUBDIRS += tests/daemon endif if ENABLE_APPLIANCE SUBDIRS += appliance diff --git a/configure.ac b/configure.ac index 8775c4b..66ac5df 100644 --- a/configure.ac +++ b/configure.ac @@ -1775,6 +1775,8 @@ AC_CONFIG_FILES([Makefile tests/charsets/Makefile tests/create/Makefile tests/data/Makefile + tests/daemon/Makefile + tests/daemon/captive-daemon.pm tests/discard/Makefile tests/disks/Makefile tests/disks/test-qemu-drive-libvirt.xml diff --git a/tests/daemon/Makefile.am b/tests/daemon/Makefile.am new file mode 100644 index 0000000..0d2f1cd --- /dev/null +++ b/tests/daemon/Makefile.am @@ -0,0 +1,36 @@ +# libguestfs +# Copyright (C) 2015 Red Hat Inc. +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
