What types of testing does this skill cover?

This skill covers unit tests for functions and classes, integration tests for APIs and services, end-to-end tests for user flows, frontend component testing (React, Vue, or other frameworks), and CI/CD pipeline integration testing.

Does this skill work with specific testing frameworks?

No, this skill applies to JavaScript/TypeScript projects generally and is not tied to one specific testing framework, making it adaptable to various modern testing tools.

Can this skill help with test-driven development (TDD)?

Yes, applying test-driven development (TDD) is one of the core topics covered by this skill.

What should I input when using this skill?

Input a JavaScript/TypeScript testing task such as setting up test infrastructure, writing a specific test type, or integrating tests into CI/CD, and you'll receive actionable testing guidance and patterns.

Does this skill cover mocking and external dependencies?

Yes, mocking external dependencies and APIs is included as part of the testing strategies covered by this skill.

Overview

JavaScript Testing Patterns

A guide for unit, integration, end-to-end, and component testing in JavaScript/TypeScript, plus mocking dependencies and CI/CD test setup. Use when setting up test infrastructure, writing tests at any level, mocking dependencies, or integrating tests into CI/CD.

What it does

JavaScript Testing Patterns is a guide for implementing robust testing strategies in JavaScript and TypeScript applications using modern testing frameworks and best practices.

When to use - and when NOT to

Use this skill when setting up test infrastructure for new projects, writing unit tests for functions and classes, creating integration tests for APIs and services, implementing end-to-end tests for user flows, mocking external dependencies and APIs, testing React, Vue, or other frontend components, implementing test-driven development, or setting up continuous testing in CI/CD pipelines. It is not for tasks unrelated to JavaScript testing patterns or for work in a different domain or tool outside this scope.

Inputs and outputs

Given a testing task, the skill applies relevant best practices and produces actionable, verifiable testing steps matched to the scenario - unit, integration, end-to-end, component, or CI/CD test setup. Detailed patterns and examples are available in resources/implementation-playbook.md.

Who it's for

JavaScript and TypeScript developers and teams setting up or extending a test suite - unit, integration, end-to-end, component, or CI/CD-integrated - who want a consistent set of testing patterns to apply across scenarios.
