Maybe we could do: `lettuce.set(storeKey, String.valueOf(HASH_SIZE))` before we run the `ConcurrentLoopingThreads` so there would definitely be a value there. ########## File path: geode-redis/src/test/java/org/apache/geode/redis/internal/SupportedCommandsJUnitTest.java ########## @@ -41,6 +41,10 @@ "HMSET", "HSET", "HSETNX", + "HVALS", Review comment: Looks like `HVALS` is in the unsupported and supported lists. ########## File path: geode-redis/src/integrationTest/java/org/apache/geode/redis/internal/executor/hash/AbstractHashesIntegrationTest.java ########## @@ -540,6 +540,22 @@ public void testHLen() { } + @Test + public void testHLenErrorMessage_givenIncorrectDataType() { + jedis.set("farm", "chicken"); + assertThatThrownBy(() -> jedis.hlen("farm")) + .isInstanceOf(JedisDataException.class) + .hasMessageContaining("WRONGTYPE Operation against a key holding the wrong kind of value"); + } + + @Test + public void testHLen_givenWrongNumberOfArguments() { + assertThatThrownBy(() -> jedis.sendCommand(Protocol.Command.HLEN)) + .hasMessageContaining("wrong number of arguments"); + assertThatThrownBy(() -> jedis.sendCommand(Protocol.Command.HLEN, "1", "2")) + .hasMessageContaining("wrong number of arguments"); Review comment: Sorry to keep bugging y'all about this, but I'm wondering if we could switch this up to check for the full error message like we do for other commands: ``` .hasMessage("ERR wrong number of arguments for 'hlen' command"); ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
