How do I map Angular tests/test suites back to JIRA to track them?

I am struggling how to track my test coverage for an Angular app back to the requirements documentation. Currently all requirements are pages in Confluence which map to JIRA cases for tractability. However, I am not sure how to map my angular tests back to the JIRA requirement issue cases? How do most teams manage their tests to ensure their requirements are tested?

Any guidance would be appreciated.
