Aug 1, 2025Monthly summary for 2025-08: Stability and build reliability improvements. Key outcomes include stabilizing course management automation tests and tightening build configuration to reduce CI failures and improve release confidence. Specifically, the course management tests were made reliable by removing an unnecessary check on a disabled confirmation dialog and reworking the UI interaction sequence, while build reliability was improved by updating pom.xml dependencies to align with latest requirements. These changes contributed to fewer flaky tests, faster feedback cycles, and a more predictable release process.
