Master production-level testing in Next.js in just one course — and close the key gap between yourself and the level of a senior developer.
Most developers deploy projects “on a wing and a prayer.” Only a few write truly reliable tests that catch real bugs before they go into production. This course is designed to help you join their ranks.
You will learn why the “write a couple of unit tests and relax” approach doesn’t work, how to build a comprehensive testing strategy, and why 80-90% coverage does not guarantee application security. Testing is not a point, but a system.
The course is structured around three key stages:
- In-depth understanding of testing — you will learn how test architecture works, how to design stable, scalable test systems, and how to approach refactoring with confidence.
- Testing a real production application — you will work not with “toy” examples, but with a full-fledged StackOverflow analogue: authentication, server actions, database, API, AI integrations, and asynchronous processes.
- Active practical tasks — you will independently write tests for key scenarios, reinforcing real production patterns.
During the course, you will master the modern testing stack: Jest, React Testing Library, Playwright, Artillery, as well as CI/CD via GitHub Actions and CircleCI.
The course is designed for developers with solid JavaScript knowledge and basic experience with React and Next.js. No testing experience is required — you will learn everything in practice, step by step, using real production scenarios.
The result: after the course, you will be able to confidently test complex Next.js applications, catch bugs before production, and meet the requirements of mid-level and senior developers.
