Review comment: This might be better as: ``` assertThat(destinationKey).satisfiesAnyOf( key -> assertThat(jedis.smembers(key)).containsExactlyInAnyOrder(setMembers), key -> assertThat(jedis.exists(key)).isFalse()); ``` which removed the need for an AtomicReference and more directly asserts one of the conditions we're interested in, i.e. that there is nothing at the destination key, rather than just asserting that if there is something there, that it's empty. ########## File path: geode-for-redis/src/integrationTest/java/org/apache/geode/redis/internal/commands/executor/set/AbstractSDiffStoreIntegrationTest.java ########## @@ -0,0 +1,243 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one or more contributor license + * agreements.

I think 3 test cases would be sufficient; one where the destination key is a RedisSet and the diff we're producing is not empty, one where the destination key is not a RedisSet and the diff we're producing is not empty, and one where the destination key is not a RedisSet and the diff we're producing is empty. Combined with all of the coverage for the empty destination key case, this should be pretty comprehensive. -- This is an automated message from the Apache Git Service.
