Worked on enhancing the test suite for the COMP4959_Project repository, focusing on improving the validation of turn order mechanics within the game’s backend. Applied Elixir to refactor and modernize existing tests, removing outdated cases and introducing a targeted test that better reflects current gameplay logic. This approach increased the accuracy and relevance of automated testing, reducing flaky results and aligning the suite with recent code changes. Emphasized backend development and testing best practices to improve maintainability and reliability, enabling faster feedback cycles and safer releases. The work supported more confident deployments by ensuring core game functionality was thoroughly validated.
