Check List

Tests

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

• Manual test (add detailed scripts or steps below)

>>> use temp
OK
>>> check_and_set a -c b -t exist -s b1 -v c1 -r
hash_key: "a"
check_sort_key: "b"
check_type: exist
set_sort_key: "b1"
set_value: "c1"
set_value_ttl_seconds: 0
return_check_value: true

Set failed, because check not passed.

Check value not exist.
