Course Description:

Are you ready to elevate your Next.js skills to the next level? 🚀 With this course, you'll dive deep into testing your Next.js applications from top to bottom. Tests are your safety net, ensuring that your app functions as expected and free of those dreaded, unexpected bugs. In today's competitive job market, knowing how to write tests is not just a bonus—it's essential.

Comprehensive Next.js App Testing: This course meticulously covers all aspects of testing a Next.js application, including:

• UI Unit Tests: Testing the user interface elements for functionality and aesthetics.
• API Unit Tests: Ensuring your backend APIs deliver the correct data under the right conditions.
• Next.js Routes: Verifying that each route in your Next.js app behaves as designed.
• Cached Pages: Testing static pages cached by Next.js for correctness.
• Data Updates: Ensuring new or updated data is handled correctly, both in the cache and through SWR's refresh interval.
• Authentication: Validating that only authorized users can access certain parts of your app.
• End-to-End (E2E) Tests: Simulating a complete user flow from start to finish for a full picture of app functionality.

Technologies Featured: The course leverages a variety of testing tools and technologies:

• Jest: For comprehensive unit testing.
• React Testing Library: To test the UI components in isolation.
• Mock Service Worker (MSW): For simulating network requests and responses.
• Cypress: For end-to-end testing.
• Cypress Testing Library: To integrate React Testing Library with Cypress for seamless E2E testing.

Testing Techniques: You'll learn a multitude of testing techniques, including:

• Using a test database to simulate real-world data scenarios.
• Employing environment variables to manage different test environments.
• Utilizing Jest module mocking to isolate tests and prevent side effects.
• Exploring the definitions and tradeoffs behind testing to make informed decisions about what to test.

Practice What You've Learned:

The course is interactive, with "code quizzes" to challenge your understanding by writing code based on the concepts covered. For sections that are more concept-heavy, multiple-choice quizzes will help reinforce your learning.

Test a Pre-written App:

To provide a real-world context, a Next.js app has already been written for you to test. This app is a concert venue platform called "Popular Concert Venue." It features shows from quirky bands like The Joyous Nun Riot and Avalanche of Cheese. The app is designed to be tested with randomized, mad-libs style band descriptions and images, adding an element of fun to the learning experience.
