Nov 1, 2025Clinical-Genomics/cg — 2025-11 monthly summary: Delivered targeted test automation improvements for critical startup work and a major bug fix to the delivery messaging path. Key contributions include Nallo start-available integration tests and dev-start-available test coverage with parameterized tests and sample creation utilities, plus refined test structure and config-file creation verification. A separate refactor made delivery message generation independent of app tags, enabling Microsalt workflows and fixing related errors by always using the delivery message path. These changes increase test coverage, reliability, and maintainability, and support Microsalt use cases for production workflows.

Sep 1, 2025Month: 2025-09 — Clinical-Genomics/cg delivered improvements to start-available automation with stronger reliability and observability. Implemented end-to-end integration tests using pytest-httpserver, gated test execution to explicit requests to reduce CI noise, and enhanced logging to report the number of cases to be started across Balsamic, MIP, and Nextflow pipelines. Updated CI to include these tests, enabling earlier regression detection and better auditability. No major bugs fixed this month in cg. Overall impact: increased automation confidence, clearer pipeline workload visibility, and stronger cross-pipeline coordination.

Aug 1, 2025August 2025 (2025-08) monthly summary for Clinical-Genomics/cg: Delivered a targeted refactor of start command generation for Microsalt workflows. The start command construction was moved from the Submitter class to the MicrosaltCaseConfig model, introducing a new get_start_command method. This change removes the WORKFLOW_LAUNCH_COMMAND_MAP, reducing runtime decision points and simplifying future maintenance. The effort included comprehensive unit tests validating the new method and behavior, increasing startup reliability and test coverage. The change is tracked under commit 64a4260542553e54223d267367fdc4e1b9aa8d5c (Rework subprocess submitter (#4549)(patch)).

Jun 1, 2025June 2025 – Clinical-Genomics/cg: Delivered a reliability enhancement for the Ticket Inbox Rsync workflow. Added a dedicated inbox-creation job executed before rsync to prevent race conditions, and refactored Slurm sbatch header generation to support optional headers and enforce dependency on successful inbox creation. This improves end-to-end ticket processing reliability, reduces intermittent rsync failures, and strengthens batch job orchestration. The change reduces manual troubleshooting and accelerates ticket ingestion and data movement, aligning with business goals for robustness and efficiency.
