improve-ut — Автоматическое обновление юнит-тестов на основе изменений кода

--- name: improve-ut description: "Analyzes changed files and improves unit test coverage using project-specific testing conventions from .trellis/spec/ unit-test specs. Determines test scope (unit vs integration vs regression), adds or updates tests following existing patterns, and runs validation. Use when code changes need test coverage, after implementing a feature, after fixing a bug, or when test gaps are identified." --- # Improve Unit Tests (UT) Use this skill to improve test coverage after code changes. ## Usage ```text $improve-ut ``` ## Source of Truth Discover and read unit-test specs dynamically: ```bash # Discover available packages and their spec layers python3 ./.trellis/scripts/get_context.py --mode packages ``` Look for packages with `unit-test` spec layer in the output. For each discovered `unit-test/` directory, read all relevant spec files inside it (for example `index.md`, `conventions.md`, `integration-patterns.md`, `mock-strategies.md`). > If this skill conflicts with the unit-test specs, the specs win. --- ## Execution Flow 1. Inspect changed files: - `git diff --name-only` 2. Decide test scope using unit-test specs: - unit vs integration vs regression - mock vs real filesystem flow 3. Add/update tests using existing project test patterns 4. Run validation: ```bash pnpm lint pnpm typecheck pnpm test ``` 5. Summarize decisions, updates, and remaining test gaps. --- ## Output Format ```markdown ## UT Coverage Plan - Changed areas: ... - Test scope (unit/integration/regression): ... ## Test Updates - Added: ... - Updated: ... ## Validation - pnpm lint: pass/fail - pnpm typecheck: pass/fail - pnpm test: pass/fail ## Gaps / Follow-ups - <none or explicit rationale> ```
