Unit Testing

Monitor dbt execution using the dbt Artifacts package. Use this skill when you need to track test and model execution history, analyze run patterns over time, monitor data quality metrics, or enable programmatic access to dbt execution metadata across any dbt version or platform.

Apply context-driven testing principles where practices are chosen based on project context, not universal 'best practices'. Use when making testing decisions, questioning dogma, or adapting approaches to specific project needs.

Advanced visual regression testing with pixel-perfect comparison, AI-powered diff analysis, responsive design validation, and cross-browser visual consistency. Use when detecting UI regressions, validating designs, or ensuring visual consistency.

WCAG 2.2 compliance testing, screen reader validation, and inclusive design verification. Use when ensuring legal compliance (ADA, Section 508), testing for disabilities, or building accessible applications for 1 billion disabled users globally.

AI agents as force multipliers for quality work. Core skill for all 19 QE agents using PACT principles.

Apply the Holistic Testing Model evolved with PACT (Proactive, Autonomous, Collaborative, Targeted) principles. Use when designing comprehensive test strategies for Classical, AI-assisted, Agent based, or Agentic Systems building quality into the team, or implementing whole-team quality practices.

Apply London (mock-based) and Chicago (state-based) TDD schools. Use when practicing test-driven development or choosing testing style for your context.

Run tests using justfile tasks (just test-local for local development, just test-unit, just test-it). Use after implementing features, fixing bugs, when user mentions tests, validation, or before commits. Primary command is 'just test-local' which runs without external dependencies.

Measure quality effectively with actionable metrics. Use when establishing quality dashboards, defining KPIs, or evaluating test effectiveness.

Advanced exploratory testing techniques with Session-Based Test Management (SBTM), RST heuristics, and test tours. Use when planning exploration sessions, investigating bugs, or discovering unknown quality risks.

Use when running or gating tests; standardizes uv run commands and JSON checks.

Comprehensive guide for creating REST API endpoints in Bruno. Use when working with Bruno collections, creating .bru files, configuring API endpoints, setting up authentication, writing pre/post-request scripts, organizing Bruno collections, or testing REST APIs with Bruno.

Use when writing or updating tests (Python, JS/Hoot, integration, or tours).

Run Tecton plan and tests via Pants in the data-science repo. Handles long-running commands with proper output capture to avoid truncation.

Use when writing unit tests for Angular components, services, pipes, or directives. Triggers on requests to "write tests", "add tests", "create spec", "test this component", or when test files need to be created/modified.

Expert performance engineer specializing in system optimization, bottleneck identification, and scalability engineering. Masters performance testing, profiling, and tuning across applications, databases, and infrastructure with focus on achieving optimal response times and resource efficiency.

Systematic 9-dimension validation machine for testing ideas before building. Covers problem severity, market sizing, timing, competitive moats, unit economics, founder-market fit, technical feasibility, GTM clarity, and risk profile. Makes GO/NO-GO decisions based on evidence, not assumptions.
