From: "Daniel P. Berrange" <berrange@redhat.com> When debugging a failing test with many test cases, it is useful to be able to skip most tests. Introducing a new environment variable VIR_TEST_RANGE=N-M enables execution of only the test cases numbered N-M inclusive, starting from 1. For example, to skip all the cgroup tests except 2 $ VIR_TEST_RANGE=2-3 VIR_TEST_DEBUG=1 ./vircgrouptest TEST: vircgrouptest 2) New cgroup for driver ... Unexpected found LXC cgroup: 1 libvirt: Cgroup error : Failed to create controller cpu for group: No such file or directory FAILED 3) New cgroup for domain driver ... Cannot find LXC cgroup: 1 libvirt: Cgroup error : Failed to create controller cpu for group: No such file or directory FAILED Signed-off-by: Daniel P.
