Out of the box, Polarion ALM provides a good foundation for test planning (Test Plan) and test execution (Test Runs). But what if you do not plan your test cases upfront, and instead you need to make sure the test scenarios related to user stories covered in current sprint are executed and verified. Or better yet, define who should actually verify the product increments of the actual sprint.
We have designed a framework with which users can still separate a test specification (test cases) and test results (test records) and have the testing primarily driven by user stories.
