WIP: test: debug TEST-41 failure on Ubuntu CI
 2019-10-18 18:36:48 -07:00
Dan Streetman dfec314d41 test: correct TEST-41 StartLimitBurst test 
TEST-41 verifies that the StartLimitBurst property will correctly
limit the number of unit restarts, but the test currently doesn't
adjust the StartLimitIntervalSec which defaults to 10 seconds.

On Ubuntu CI, running under un-accelerated qemu, it can take more than
10 seconds to perform all 3 restarts, which avoids the burst limit,
and fails the test.

Instead, specify a long StartLimitIntervalSec in the test, so we can
be sure to correctly test StartLimitBurst even on slow testbeds.

Fixes .

This appears to be failing on Ubuntu CI due to short sleep duration
waiting for the service-restarts to complete, but doubling the
sleep from 5 to 10 seconds didn't appear to help, so let's blacklist
this on Ubuntu CI while debugging the test failure.
