These changes improve test coverage, reduce feedback cycles, and lay groundwork for backup capabilities in production deployments.

May 2025: PMM CI improvements in Jenkins pipelines delivering higher nightly test reliability, expanded Nomad and multi-client test coverage, and PMM v3 matrix upgrade validation. Focused on business value: fewer nightly failures, broader validation across client configurations, and stronger upgrade risk detection across environments.

April 2025: Key features delivered and bugs fixed across Percona-Lab/jenkins-pipelines and percona/pmm-ui-tests. Features delivered include an upgraded testing framework for PMM v3 with a new Jenkins pipeline runner and expanded upgrade test coverage, plus MySQL 8.4 support in PMM upgrade/UI tests through pipeline/config updates. Major bugs fixed include modal visibility correctness across sessions and stabilization of Percona Server integration tests by adjusting DB connection ports and refining query-count validation. These efforts improve upgrade reliability, broaden test coverage, and reduce flakiness in UI and integration tests. Technologies demonstrated include Jenkins pipelines, Docker image tagging, test orchestration, localStorage-based UI state handling, database connectivity tuning, and Query Analytics validation.

Month: 2025-03 — Percona-Lab/jenkins-pipelines delivered a major PMM Package Testing Pipeline Enhancement. It introduces a matrix of tests across OS distributions and package types, with new parameters for tarball links and client configurations, and reorganized stages that run tests in parallel to boost efficiency and coverage. This work is tracked in commit 7e91a54422c3075a18bab2504e2755c0bc444ee9 (PMM-13803: Package test for pmm matrix (#3235)). Major bugs fixed: none documented this month. Overall impact: faster and more robust PMM package testing, enabling broader validation across environments and accelerating release readiness. Technologies demonstrated: Jenkins CI/CD pipelines, matrix-style testing, parameterization, and parallel execution across multiple OS/package combinations.

February 2025 monthly summary focusing on delivering features, fixing pipeline issues, and strengthening test infrastructure across Percona-Lab/jenkins-pipelines and percona/pmm-ui-tests. Key changes delivered automated reporting and migration tooling, addressed a critical network issue in the testing pipeline, and improved test reliability across UI tests. Highlights include: - UI test reporter integration in pipelines and added credentials for automated UI tests, enabling reporter functionality in CodeceptJS tests. - PMM v2 to v3 migration pipeline: automated environment setup, tag/config management, PMM client config, pre-migration and migration tests, log collection, and build-status reporting. - Network connectivity fix in the testing pipeline to ensure Docker containers communicate on the pmm-qa network. - PMM Migration Test Suite Reliability Improvements in pmm-ui-tests: consolidation of two infra changes, including migration test robustness improvements and a fix for Aurora monitoring DataTable v2 issues.

January 2025 monthly summary for Percona-Lab/jenkins-pipelines. Focused on cross-distro PMM 3 client installation reliability and automated PMM 3 development client provisioning to accelerate testing and deployment pipelines. Delivered two main outcomes: 1) Cross-distro PMM 3 client install adjustments and 2) PMM 3 development client provisioning. These changes reduce environment-specific issues, shorten setup times, and improve automation coverage for PMM 3 adoption in CI/CD workflows.

December 2024 monthly summary focusing on key accomplishments, major bug fixes, and overall impact across two repositories.
