SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams eliminate deployment surprises and flaky releases by building reproducible container images, orchestrating development and test environments, and establishing layered automated testing and observability so bugs are caught before production.

Core Features & Use Cases

  • Containerization & Build Optimization: Design multi-stage Dockerfiles that minimize image size and surface build caching opportunities.
  • Local-to-CI Orchestration: Configure Docker Compose to link Redis, SQLite and FastAPI for deterministic integration testing and developer workflows.
  • Testing Pyramid Implementation: Set up Vitest for front-end unit tests, pytest-asyncio for backend async tests, and Playwright for end-to-end scenarios.
  • CI/CD & Observability: Create GitHub Actions workflows that run layered tests, build and publish images, and inject Sentry DSN with logging export for production error tracking.
  • Use Case: Turn a partially tested microservice into a production-ready artifact by adding container optimizations, comprehensive tests, a CI pipeline, and Sentry instrumentation to reduce incident mean time to detection.

Quick Start

Use the devops-testing-engineer skill to generate an optimized multi-stage Dockerfile, a Docker Compose development stack with Redis and SQLite, Vitest and pytest-asyncio test suites, Playwright e2e tests, and a GitHub Actions workflow with Sentry integration for your repository.

FAQPage Schema
How do I set up a Docker Compose stack with Redis and FastAPI for integration testing?

Set up Docker Compose orchestration to link Redis, SQLite, and FastAPI for deterministic integration testing. This environment creates reproducible local development workflows that mirror CI pipelines to catch bugs early.

What's the best way to structure Vitest and pytest-asyncio tests for a containerized application?

Structure a layered testing pyramid using Vitest for front-end unit tests and pytest-asyncio for backend asyncio tests. This strategy isolates frontend and backend logic validation before running broader integration checks.

How do I inject Sentry DSN in GitHub Actions workflows for CI/CD pipelines?

Inject Sentry DSN during GitHub Actions workflows to enable production error tracking and logging export. This CI/CD integration ensures runtime exceptions are captured immediately after deployment, reducing incident detection time.

Does multi-stage Docker build optimization reduce image size for FastAPI and Redis services?

Multi-stage Docker builds minimize final image size and surface build caching opportunities for FastAPI and Redis services. This optimization creates reproducible container images, eliminating deployment surprises and flaky releases.

Can I use Playwright for end-to-end testing in a Docker Compose development environment?

Playwright end-to-end tests run within the Docker Compose development environment to validate complete user scenarios. This ensures the containerized FastAPI application and its Redis dependencies function correctly together before release.

Why does my GitHub Actions workflow fail when running layered tests in Docker containers?

GitHub Actions workflows must properly orchestrate Docker Compose to link Redis and SQLite before running layered tests. Ensure the CI workflow builds optimized images and configures the testing pyramid correctly to prevent flaky releases.
