// Notes: How to write a new module integrate test case in logservice?
// 1. cp test_ob_simple_log_basic_func.cpp test_ob_simple_log_xxx.cpp
// 2. modify const string TEST_NAME, class name and log file name in
// test_ob_simple_log_xxx.cpp
// 3. add ob_unittest_clog() item and set label for test_ob_simple_log_xxx in
// unittest/cluster/CMakeFiles.txt
// 4. write new TEST_F
