February 2025 monthly summary for RedHatInsights development across rhc and yggdrasil. Focused on delivering business value through reliability, improved UX, broader testing, and clearer logging. Key outcomes include securing correct content behavior, hardening CLI interactions, expanded test and documentation coverage, and robust service integration testing. Key features delivered and major bugs fixed (selected highlights): - Content Feature Enablement Validation (rhc): Prevent using --content-template when the content feature is disabled by adding a validation. (commit 16c18a3a6081760f3f1d3623521e21f23da13478) - Connect Command robustness and UX (rhc): Improved reliability and user experience: validate authentication options for JSON output, dynamically display feature IDs in help, and improve exit code handling for incorrect CLI usage; ensure machine-readable output is directed to stdout when appropriate. (commits bb3aa93638f7c9d3024dd050e9aa29aff25c465f; 7dc9aeb736ade3dd4eab0dac8e020e83d4f1fae6; fe3928748dd6d5e7a04b08b92ec26cfaf8b3e1f9; 8bf15f3137e2283266f6515f6273b4238aaff2b2) - Testing, Documentation, and Man Page Coverage Improvements (rhc): Added integration tests for connect JSON output, TESTING.md, expanded man-page coverage, and ensured tests cover invalid option combinations.
