Holger Freyther gerrit-no-reply at lists.osmocom.orgHello Pau Espin Pedrol, Harald Welte, Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/6918
to look at the new patch set (#6).
ms: Add a first test to use all parts of the system
This is an interim solution but is bringing all parts together.
We will need to:
* Abstract this into a base class
* Be able to mix different tests without interfering with each
other (e.g. 10k LU tests, 2k SMS sending)
* The event loop will need to handle multiple timers/timeouts
* Stats printing should print more information and test pass/fail
* The test should quit early if everything has already passed
