Use stress command to catch flaky tests.

Example

For example, I’m trying to catch a panic in TestPostToCommunityChat in MessengerCommunitiesShardingSuite.

1. Compile the package tests into a binary

   go test -c ./protocol
   

2. Run stress tests:

   stress \\
   	-count 1000 '
   	./protocol.test \\
   	-test.run TestMessengerCommunitiesShardingSuite \\
   	-testify.m TestPostToCommunityChat
