Commit Message

xds: eliminate test verification for nondeterministic behaviors (#8172)

When the ring_hash LB policy enters TRANSIENT_FAILURE, it tries to connect one of the IDLE subchannels. Which subchannel to be connected to is non-deterministic, it just choose the first one from the subchannels map.

The existing test creates 4 subchannels, brings down 2 of them to let ring_hash LB policy enter TRANSIENT_FAILURE. But which one fo the remaining two subchannels to be kicked off connection is nondeterministic. This introduces trouble for verifying the behavior. This change simplifies the test, to only create 3 subchannels so that there is only one single subchannel remaining in IDLE after bringing the other two down. We are able to easily verify the behavior of ring_hash LB policy requesting connection for that one subchannel.
