COMMENT "a"bc" to COMMENT "a\"bc"
```
A reword suggestion.
Reasons: Before my change, the statement is "If this change need a document change, I have updated the document",
and there is a grammar error in it evidently: "change" cannot be paired with "need".
Either "changes need" or "change need" will be ok at the grammar level.
According to the context, "changes need" will be better.
Now, the statement is "If these changes need document changes, I have updated the document".
1. Rename run-ut.sh to run-be-ut.sh
2. Find all test files from build dir instead of declaring separately in the script
3. Add gtest output to collect the result of unit test.
