Worked on modernizing the test suite for the spryker/robotframework-suite-tests repository, focusing on updating API error handling tests related to empty cart UUIDs in the RfQ API. Addressed a bug by aligning Robot Framework test cases with recent API contract changes, specifically updating expected response statuses and error codes to reflect new behaviors for blank UUID scenarios. Utilized API testing methodologies and Robot Framework scripting to ensure the suite accurately validated the revised error handling logic. This work improved test reliability ahead of the general availability release, demonstrating attention to evolving API specifications and maintaining robust automated test coverage.
