ASSERT failures result in immediate termination of the test. EXPECT returns a failure but continues execution. Reserve ASSERT for required functionality (node initialization, queue creation, etc) where the rest of the test cannot run if that call fails. Use EXPECT everywhere else Change-Id: I1c11326fc3ae22b50fa83b07b3b49af1e1f4e69e
