Developed and integrated a comprehensive suite of MIRV execution tests and performance benchmarks for the openfrontio/OpenFrontIO repository, focusing on validating core game mechanics and establishing baseline performance metrics. Leveraging TypeScript and unit testing frameworks, the work included designing tests for launch, targeting, and warhead distribution scenarios, as well as benchmarking throughput across sparse, dense, and large-world map conditions. All tests were structured to align with repository conventions and prepared for continuous integration and quality assurance processes. This effort enhanced test coverage, provided actionable performance insights, and laid the groundwork for future UI and translation verification within the game development workflow.
