Developed and delivered Activity API integration tests and example scenarios for the ExpediaGroup/xap-java-sdk repository, focusing on enhancing test coverage and developer guidance for the Activity API. The work involved creating new Java files to support both Activity listings and details scenarios, as well as implementing integration tests to validate these features. Integration testing and Java development skills were applied to ensure reliable API interactions and to facilitate onboarding for other developers. Additionally, updated copyright years and license headers on all new files to maintain licensing compliance. This contribution improved the SDK’s reliability and strengthened its overall quality for future development.
