Simulation as Acceptance Test
For games and complex interactive systems, unit tests verify correctness but batch simulation verifies balance. Run N automated games, record metrics, and treat the first run's numbers as a baseline. Future changes must either match the baseline or explain the deviation.
Acceptance Testing with Playwright
Use BFS link crawling and smoke tests against live URLs to catch broken navigation and UI regressions before users do
Live Infrastructure for Integration Testing
When local services are already running, skip mocks and test the real pipeline end-to-end
Mock vs Live Testing Trade-offs
A decision framework for when to mock dependencies and when to test against real infrastructure
Preflight Gates as Local CI
Run the same checks CI will run before pushing to prevent the most common build failure patterns
Skill-Driven Workflow Automation
Composable slash-command skills turn multi-step developer workflows into repeatable single-command operations that enforce guardrails automatically
Test Pyramid for Static Sites
Layer unit, integration, and acceptance tests so each catches what the others cannot in a static site with a backend API
Testing Cross-Repo Content Pipelines
Validate harvested content spanning multiple repositories with severity levels, slug uniqueness, schema enforcement, and link resolution
