Hi Bruce,
Thank you for the review.

Are you concerned about new test case or new test case file?
>From a new test case perspective, we are testing a new use case, hence we need it. May be few parts can be combined such as generating the keys.
>From a new test case file perspective, combining this use case with existing files was making the code difficult to manage. Hence we decided to add a new file.
There are more test cases because of multiple configuration options present in hash table.
