Is their any test case repository(Storing test case) in JIRA

Pretty much answered by the answers to questions you've already asked - see https://answers.atlassian.com/questions/37041901 as an example.

To save you re-reading though, no.  JIRA is an issue tracker, not a test case manager.  There are addons that can do it, and integrations for test-case managers, and you should have a look in the marketplace to see which one(s) might suit you.
