Testing JavaScript

• Understand the importance of automated testing in ensuring code reliability and user trust.
• Learn how to implement a four-layer testing strategy, covering static analysis, unit tests, integration tests, and end-to-end (E2E) tests.
• Gain the skills to use modern tools like Jest, Cypress, and DOM Testing Library for testing JavaScript applications.
• Develop the ability to apply testing techniques across various JavaScript frameworks, including React, Angular, and Vue.
• Achieve confidence in shipping production-ready code that minimizes bugs and improves maintainability.

This comprehensive course, led by expert Kent C. Dodds, provides an in-depth guide to testing JavaScript applications. It covers essential techniques and tools for automated testing, helping developers deliver reliable, bug-free software. The course is designed to be framework-agnostic, allowing learners to apply the principles across any JavaScript-based project.
