User Story As a test engineer, I want to ensure all 49 tests pass at >=99% rate on all 5 platforms so that the test suite meets OTE conformance requirements. Description This story focuses on final validation and tuning to achieve the >=99% pass rate threshold required for OTE migration. After fixes from Story 2, this involves fine-tuning, addressing any remaining edge cases, and validating sustained pass rates across all platforms. This is a validation-focused story that ensures the work from Story 2 has achieved the required quality bar. Required AWS platform: >=99% pass rate for all 49 tests Azure platform: >=99% pass rate for all 49 tests vSphere platform: >=99% pass rate for all 49 tests GCP platform: >=99% pass rate for all 49 tests Nutanix platform: >=99% pass rate for all 49 tests Documentation of final pass rates per platform Nice to have Identification of tests approaching but not exceeding 99% for future monitoring Performance benchmarks for test execution times Engineering Details Target: All 49 tests at >=99% pass rate All 5 platforms must meet threshold: AWS, Azure, vSphere, GCP, Nutanix Measurement period: Minimum 1 week of consistent results OTE conformance requirement: >=99% pass rate Use CI data from platform periodic runs Acceptance Criteria AWS platform shows >=99% pass rate for all 49 tests Azure platform shows >=99% pass rate for all 49 tests vSphere platform shows >=99% pass rate for all 49 tests GCP platform shows >=99% pass rate for all 49 tests Nutanix platform shows >=99% pass rate for all 49 tests Pass rate data is validated over at least 1 week of test runs Documentation confirms all platforms meet OTE conformance requirements
