Worked on the google/filament repository to implement configurable build-time testing for Filament components, focusing on optimizing build systems and configuration using CMake. Developed a build option that enables component tests only when required, updating the build process to conditionally include backend tests based on this setting. This approach reduced continuous integration and local build times by avoiding unnecessary test executions in non-testing builds, streamlining resource usage while maintaining test coverage when needed. Leveraged skills in build configuration, CMake, and testing to ensure that test builds are performed only when explicitly enabled, improving feedback loops and overall development efficiency for the project.
