Features and purpose

Write minimal, focused tests following KISS and YAGNI principles - test only core user flows during development, defer edge case testing, test behavior not implementation, use clear test names, mock external dependencies, and ensure fast test execution. Use this skill when creating test files, writing unit tests, integration tests, or component tests. Use when working with test frameworks (Jest, Vitest, pytest, RSpec, JUnit, Mocha), when deciding what to test and when, when writing test cases for critical paths and primary workflows, when mocking external services or databases, or when ensuring tests run quickly for developer productivity. Apply when creating test files (.test.ts, .spec.ts, test_*.py, *_test.go) or when implementing behavior-driven test cases.
