Roman Puchkovskiy updated IGNITE-21471:
---------------------------------------
Description:
sendMessagesOneChannel and sendMessagesTwoChannels block a Netty thread to do
their assertions. We cannot control which Netty thread does what (actually, we
can, but it's very tricky, non-obvious and fragile). As a result, sometimes
(very rarely, though) the latter test flacks.
It seems that in sendMessagesTwoChannels we can just assert that after sending
2 messages using different channels exactly 2 channels get opened.
sendMessagesOneChannel is only used to test that the approach for blocking the
Netty threads used in sendMessagesTwoChannels works (so it's a test for a
test). If we change the latter to not using blocking, the former can be just
removed.
