Management has asked me to 'go through my test cases' with them, so I created a filter to gather all of my test cases so that I could export them and then walk through each test explaining what it do...
Not sure exactly if you're using issue links with the test cases or another jira field, but this is what I got using JQL to search for issuelinks. You'll have to add a column in for "links" on the search page, and unfortunately you cannot filter this column (like summary or priority). My issue links are not consistent so I did the search a few different ways:
project = KIM AND issuetype = Test AND issueLinkType = "relates to"
project = KIM AND issuetype = Test AND issueLinkType = "blocks"
