Does it support snapshot testing?

Yes, it integrates with Bun's native snapshot testing for verifying complex outputs in the __snapshots__ directory.

What is the primary purpose of the Outfitter Testing skill?

It provides standardized testing patterns and utilities specifically designed for @outfitter/* packages, leveraging the Bun test runner for high performance.

Can I test Model Context Protocol (MCP) tools with this skill?

Yes, it includes a dedicated createMcpHarness utility specifically designed to invoke tools and validate input schemas and results.

How does this skill handle file system side effects during tests?

It provides a withTempDir utility that creates an isolated directory for file operations and automatically cleans up after the test finishes.

How do I mock environment variables using this skill?

The skill provides a withEnv utility that allows you to temporarily set environment variables for the duration of a specific test block.

Streamlines testing for Outfitter packages using specialized harnesses, deep-merged fixtures, and Bun-native patterns.

The Outfitter Testing skill provides a comprehensive suite of patterns and utilities for testing @outfitter/* packages. It enables developers to test handlers directly without transport layers, utilize specialized harnesses for CLI and Model Context Protocol (MCP) tools, and manage complex test data with deep-merged fixtures. By providing built-in utilities for environment mocking, temporary directory isolation, and context spying, it ensures that testing remains fast, isolated, and reliable within the Bun ecosystem.
