In April 2025, Geir Storli modernized the test infrastructure for the vespa-engine/vespa repository by migrating core test suites to Google Test, focusing on components such as the query builder, file header, and transaction log client. Using C++ and CMake, he standardized test assertions and replaced ad-hoc exception handling with clearer, framework-based checks. This work reduced test fragility and improved the clarity of test outcomes, resulting in faster CI feedback and lower maintenance overhead. By consolidating test patterns and leveraging gtest, Geir enhanced the reliability of critical code paths and made the test framework more accessible for future contributors.
