Thank you for summarizing this info!

FWIW, if you and Amos decide to switch to another unit test platform, I
will not object to such a switch, provided the transition is instant. We
do not have enough resources to properly write and maintain unit tests
using one platform IMO. We certainly do not have enough resources for
two platforms.
