This feature is available in QAlity Plus - Test Management for Jira exclusively.
You can filter your test cases by project, Jira statuses, and text.
Project Filter
You can choose from all the projects you have access to. You can view more than one project at a time. If you want to display all projects, remove all individual project selections from the 'Project' filter.
Status Filter
The 'Status' filter uses the statuses that are assigned to your projects. This means that your custom statuses can also be displayed. You can view more than one status at a time. If you want to display all statuses, remove all individual status selections from the 'Status' filter.
Remember that these are Jira issue statuses, not test case execution statuses.
Text Filter
You can also filter your test cases by text. The filter will show all test cases that have the text you are searching for included in the summary.
