testability

What I Do

Ensure every feature you build is testable from the start. This skill teaches:

1. Testing pyramid (fast → slow)
2. API exposure patterns for testability
3. Local testing setup
4. Integration with staging tests
5. When to use each testing layer

Core Philosophy

"If you can't test it locally, you can't test it."

Every feature should be testable at multiple levels. Design for testability, don't bolt it on later.
