Hi @ustcweizhou
Guess what... we are all busy! :)
I will give a Look Okay to Me to your changes, get those in and improve it,
but for this last time only.
If we keep saying we are busy to test our changes, we won't improve the
software we rely to run our customers' platforms. Next change without marvin
tests will get a -1 from me.
Cheers,
Wilder
