During December 2024, JGoshi developed a targeted testing capability for the microsoft/STL repository, focusing on improving continuous integration efficiency. They introduced a dedicated CMake target, 'test-only-edg', which enables selective execution of EDG tests, and extended the Python-based test infrastructure by adding a corresponding parameter in params.py and updating tests.py to honor this flag. This approach allowed the team to run only EDG-specific tests when needed, reducing unnecessary test execution and accelerating feedback cycles. JGoshi’s work demonstrated depth in build system configuration, Python scripting, and test automation, resulting in a more focused and reliable CI process for the project.
