Why does the skill insist on using 'bun run test' instead of 'bun test'?

Using 'bun run test' ensures that Vitest is used as the test runner, which provides a richer feature set and better compatibility than Bun's built-in basic runner.

Can this skill help with monorepo testing?

Yes, it includes specific expertise in Vitest's Projects mode for orchestrating tests across multiple workspaces in a monorepo.

Does it support API testing?

Yes, it provides specialized patterns for testing Hono routes and other HTTP endpoints, including contract testing and integration flows.

Which testing frameworks does the Test Engineer skill support?

The skill primarily focuses on Vitest for unit and integration testing, and Playwright for end-to-end (E2E) browser automation.

How does this skill handle code quality?

It uses Biome for high-performance linting and formatting, providing standardized configurations and pre-commit hook recommendations.
