Check List

Tests

There are a lot of function tests in test_check_and_mutate.cpp.

• Manual test (add detailed scripts or steps below)

>>> use temp
OK
>>> exist a b 
False

>>> check_and_mutate a -c b -t exist -r
Load mutations, like
  set <sort_key> <value> [ttl]
  del <sort_key>
Print "ok" to finish loading, "abort" to abort this command
>>> set b1 c1

Mutate failed, because check not passed.
