Re-testing in the Conformance Test Suite (CTS)

Question

If I find a defect when conformance testing and need to update and re-deploy code as a result, do I have to repeat all the previously passed Conformance Test Suite (CTS) test scenarios again, or do I only need to repeat the one which failed due to the defect?

Answer

Each scenario must be executed in a single session with each step running sequentially. A scenario cannot be reinitiated without commencing from the first step. For example, if a Participant fails on step 4 of 10 within Scenario 3 they will need to re-execute Scenario 3 in its entirety until it achieves a 100% pass.
