Seems the failed reason in oom02/5 is not testcase issue, it just because New API sets
test time in 5mins.The
test_teststructure has .timeout variable that, if set, overrides the default timeout. All you need to do is to to measure how long the test takes, then multiply it by something as 2 to be on a safe side and set the .timeout correspondingly.
OOM tests depend on amount of RAM+swap, so it's going to vary a lot. I'd say safe side is in order of hours.
Other options that come to mind:
- formula based on amount of RAM and swap
- we measure how long it takes to fill 1GB of RAM/swap, and scale that up
- we run all OOM tests in mem cgroup with fixed mem/swap limit, and set timeout according to worse case / slowest system
