FERC — Post-Patching Production Sanity Test Automation
Background
The Federal Energy Regulatory Commission (FERC) manages a wide portfolio of mission-critical applications that support regulatory operations across the energy sector. To maintain security and stability, monthly operating system and application patches were applied across environments. Each patch cycle required extensive validation to ensure that applications remained functional and reliable after updates.
Challenge
The post-patching validation process was highly resource-intensive. Each month, more than thirty applications had to be tested manually, requiring a team of eight testers working for a full day. This repetitive cycle consumed significant QA resources, created backlogs, and delayed deployments. While essential for system stability, the manual approach made it difficult to keep pace with frequent production changes and slowed the delivery of new features.
Solution
Our team implemented a production automation strategy to streamline post-patching validation. Comprehensive automated suites were developed to verify functionality across all applications, ensuring that critical workflows were smoke tested consistently and efficiently. The automation was designed to run unattended, producing complete reports in minutes instead of hours. In addition to monthly cycles, the solution enabled on-demand execution whenever patches, configuration changes, or new features were introduced. Knowledge transfer sessions were conducted with QA staff to ensure sustainable adoption and long-term maintainability.
Results
- Monthly post-patching validation reduced from 8 hours (8 testers) → 30 minutes unattended
- Sanity test coverage achieved across 30+ applications in every cycle
- On-demand execution enabled rapid validation for out-of-cycle changes
- QA resources were freed to focus on higher-value analysis and oversight
