Does this skill help with End-to-End (E2E) testing?

Yes, it includes specialized guidance and implementation templates for E2E testing using modern tools like Playwright and Cypress.

What is the recommended testing structure?

The skill advocates for the Testing Pyramid: 70% Unit tests for speed, 20% Integration tests for contracts, and 10% E2E tests for critical user journeys.

Which programming languages does this skill support?

Designing Tests provides specific templates, framework recommendations, and best practices for JavaScript, TypeScript, Python, and Go.

How does it improve code coverage?

The skill provides a strategy for identifying what to cover, including business logic and edge cases, along with JSON configurations for setting coverage thresholds.

Can it help with mocking external APIs?

Absolutely. It includes strategies and code examples for mocking external services, databases, and APIs using tools like MSW and fake timers.

Streamlines the creation and optimization of comprehensive testing strategies across unit, integration, and E2E layers.

소개

Designing Tests is a specialized Claude Code skill that provides standardized workflows and implementation patterns for building robust software testing infrastructures. It guides developers through the entire testing lifecycle—from selecting the right frameworks for JavaScript, Python, or Go to defining coverage thresholds and implementing the Arrange-Act-Assert (AAA) pattern. Whether you are improving code coverage, debugging flaky tests, or setting up a testing pyramid from scratch, this skill ensures your codebase remains reliable and maintainable using industry-best practices for mocking, data management, and validation.
