The concept in JIRA is:
Story - you create a story of what the feature should achieve
Task - is a development unit of work
Test - is a specific test to run - for example - test there is only one collect location available
Test Set - is a group of tests. In our case we could create a test set for - Collection Only
Test Plan - is a plan of a group of tests to complete. So we could create two plans - Collection Only Post Code On, then another for Collection Only - Post Code Off. Both would use the same tests but used for different post coding scenarios
Test Execution - is an instance of a test plan - ie one run of a test plan
JIRA SECTIONS
BACKLOG - shows development tasks in sprints - a section of work
TEST PLANS - a custom link Tim added goes to the list of current test plans
TEST EXECUTIONS - a custom link to show the list of available test executions
