Vitest test runner for JavaScript and TypeScript. Fast, modern alternative to Jest. Vite-native, ESM support, watch mode, UI mode, coverage, mocking, snapshot testing. Use when setting up tests for Vite projects, migrating from Jest, or needing fast test execution.
This skill should be used when performing AI-powered mutation testing to evaluate and improve unit test quality. It generates targeted code mutants, runs tests to identify surviving mutants, and strengthens or creates tests to kill them. Accepts a file path, directory, or defaults to git diff changed files.
pytest testing patterns for Python. Triggers on: pytest, fixture, mark, parametrize, mock, conftest, test coverage, unit test, integration test, pytest.raises.
Graph-informed mutation testing triage. Parses codebases with Trailmark, runs mutation testing and necessist, then uses survived mutants, unnecessary test statements, and call graph data to identify false positives, missing test coverage, and fuzzing targets. Use when triaging survived mutants, analyzing mutation testing results, identifying test gaps, finding fuzzing targets from weak tests, running mutation frameworks (including circomvent and cairo-mutants), or using necessist.
Advises on testing approach — when to unit test vs integration test, coverage goals, and test organization. Use when writing tests or planning test strategy.
Apex code quality guardrails for Salesforce development. Enforces bulk-safety rules (no SOQL/DML in loops), sharing model requirements, CRUD/FLS security, SOQL injection prevention, PNB test coverage (Positive / Negative / Bulk), and modern Apex idioms. Use this skill when reviewing or generating Apex classes, trigger handlers, batch jobs, or test classes to catch governor limit risks, security gaps, and quality issues before deployment.
Stage 1 spec compliance review. Triggers: /review stage 1. Verifies implementation matches design specification — functional completeness, TDD compliance, and test coverage. Do NOT use for code quality checks — use quality-review instead. Do NOT use for debugging.
Review whole-repo test quality, rerun coverage, score remaining worth-testing files, inspect slow-drift and stale test debt, and publish the next testing batch. Use every few weeks or before large breaking changes and rearchitecture.
Vitest - Modern TypeScript testing framework with Vite-native performance, ESM support, and TypeScript-first design
Defines ROI-based coverage targets with critical path identification, layer-specific targets, and explicit "don't test this" guidelines. Use for "test coverage", "coverage strategy", "test priorities", or "coverage targets".
pytest testing patterns for Python. Triggers on: pytest, fixture, mark, parametrize, mock, conftest, test coverage, unit test, integration test, pytest.raises.
Create a Frappe Framework v15 DocType with proper controller, service layer, repository, and test files. Triggers: "create doctype", "new doctype", "frappe doctype", "add doctype", "/frappe-doctype". Generates production-ready DocType with type annotations, lifecycle hooks, and multi-layer architecture integration.
