Developed parameterized test support for the JUnit OpenFeature Extension within the open-feature/java-sdk-contrib repository, focusing on enhancing test execution reliability and context management. The work involved modifying the extension to correctly intercept and manage OpenFeature contexts for each iteration of parameterized tests, ensuring accurate context handling across diverse test runs. Comprehensive test cases were implemented in Java using JUnit to validate the feature across multiple flag types, improving both test coverage and CI stability. The solution was delivered as a focused change set, demonstrating a methodical approach to software development, testing, and extension enhancement within the OpenFeature and Java ecosystem.
