Kenneth Howe commented on GEODE-3335:
-------------------------------------
The test framework with {{ManagnementTestRule}} provides the locator and the
test creates a manager and 3 members for an expected count of 5.
Flaky failures are caused by looking for an exact member count of 4. Typically
in an IDE the test runs fast, so that when {{verifyNavigationApis}} is called
there are four members returned from the {{distributedSystemMXBean}}, and after
a few iterations in {{awaitMemberCount}} the count increases to the 5.
However, when this fails in a CI pipeline, the call to {{awaitMemberCount}}
doesn't happen until the count has reached 5 - {{expectedCount = 4}} is never
seen and the await times out.
