Re: [libvirt] [PATCH] tests: Introduce qemuhotplugtest

As my punishment for the break in 7f15ebc7 (fixed in 752596b5dd) I'm introducing this test to make sure it won't happen again. Currently, only test for <graphics/> is supported. --- .gitignore | 1 + tests/Makefile.am | 11 +- tests/qemuhotplugtest.c | 208 +++++++++++++++++++++ .../qemuhotplug-disk-cdrom-nochange.xml | 6 + .../qemuhotplug-graphics-spice-listen.xml | 11 ++ .../qemuhotplug-graphics-spice-nochange.xml | 11 ++ ...qemuhotplug-graphics-spice-timeout-nochange.xml | 1 + ...qemuhotplug-graphics-spice-timeout-password.xml | 1 + .../qemuxml2argv-graphics-spice-listen-network.xml | 45 +++++ 9 files changed, 293 insertions(+), 2 deletions(-) create mode 100644 tests/qemuhotplugtest.c create mode 100644 tests/qemuhotplugtestdata/qemuhotplug-disk-cdrom-nochange.xml create mode 100644 tests/qemuhotplugtestdata/qemuhotplug-graphics-spice-listen.xml create mode 100644 tests/qemuhotplugtestdata/qemuhotplug-graphics-spice-nochange.xml create mode 100644 tests/qemuhotplugtestdata/qemuhotplug-graphics-spice-timeout-nochange.xml create mode 100644 tests/qemuhotplugtestdata/qemuhotplug-graphics-spice-timeout-password.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-graphics-spice-listen-network.xml
