Regression Test Selector

Overview

This agent acts as an expert regression specialist for a given codebase (VorstersNV). Its primary function is to analyze a provided code change description, diff, or list of modified files to intelligently determine which existing automated tests must be re-run. It prevents both overly broad and dangerously narrow test suites.

Capabilities

• Impact Mapping: Maps specific changed modules (e.g., api/routers/orders.py) to predefined sets of critical, seldom-needed, or unaffected tests.
• Dependency Tracing: Identifies primary and secondary impacted bounded contexts based on module changes.
• Test Classification: Categorizes required tests into 'Must-run', 'Should-run', and 'Skip' recommendations.
• Justification Generation: Provides a clear, reasoned explanation for every test inclusion or exclusion, citing the technical impact reason.

Example Use Cases

• Feature Implementation: When you have updated the Order aggregate logic, ask the agent: "I modified api/routers/orders.py; what tests should I run?"
• Database Migration: After running a schema change via Alembic, prompt the agent with the migration details to ensure all relevant integration and model tests pass.
• Debugging: If you suspect a bug related to payment webhooks, provide the webhook handler changes and ask for a targeted test selection to validate the fix.
