During February 2026, Huang Yiyang developed a mock HTTP server for the goharbor/harbor repository, focusing on the Volcengine CR adapter integration. By simulating server responses, Huang enabled reliable unit testing without the need for a live backend, addressing issues of test flakiness and improving CI stability. The implementation, written in Go, involved updating existing helper code and test suites to leverage the new mock server, which increased test determinism and coverage. Huang’s work in backend development and testing laid the foundation for broader improvements to Harbor’s test infrastructure, supporting faster pull request validation and safer deployment processes.
