Jun 1, 2025June 2025 — Coursemology/coursemology2: The team delivered two critical CI/CD improvements that directly enhance reliability, speed, and visibility of the release process. (1) CI/CD Infra: Fixed CircleCI Playwright dependencies installation by switching Ubuntu archive mirrors to a more reliable mirror, eliminating sporadic build failures. (2) CI/CD Coverage Reporting: Migrated coverage tooling from Cobertura to LCOV, enabled branch coverage, and improved test-result handling by collecting/persisting all reports before uploading to Codecov. Impact: more stable and faster CI feedback loops, clearer coverage signals for quality decisions, and improved pipeline reliability for every release. Technologies/skills demonstrated: CircleCI, Playwright, Linux package management, LCOV/Cobertura coverage tooling, Codecov integration, test-result orchestration, and CI pipeline reliability improvements.
