Worked on enhancing the reliability and efficiency of the bytecodealliance/wasm-micro-runtime project by expanding unit tests for Shared Heap functionality in WebAssembly workloads. Focused on validating thread safety, memory management, and concurrency through comprehensive test cases, including scenarios for memory growth and build flag cleanup. Utilized C++ and CMake to streamline the build process, notably removing the -pthread flag from WASM App builds to reduce threading-related risks and simplify configuration. This work improved regression coverage and accelerated CI feedback, contributing to more stable runtime behavior and faster development cycles, with a strong emphasis on multithreading and unit testing best practices.
