Why Test Your Code in Go? 🤔

You've heard it before: "But it works on my machine!" This common excuse can lead to headaches down the line. Quality tests are your shield and sword against bugs and regressions, ensuring that your code performs as expected, not just locally but across various environments. By investing time in writing effective unit and integration tests, you'll actually save development time, reduce maintenance efforts, and create more reliable software.

What You'll Learn 📚

This course is a deep dive into testing within the Go ecosystem, where you'll:

• Understand the Importance of Testing: Learn why testing is crucial for the health and longevity of your codebase.
• Master Go Testing Tools: Get hands-on experience with Go's built-in testing suite.
• Build and Test Real Projects: Apply your skills by creating four practical applications, each accompanied by a comprehensive test suite.
  • A Prime Number CLI
  • A Web Application for user login and profile picture upload
  • A REST API using JWT tokens and interacting with a Postgres database
  • A Single Page Web Application (SPA) demonstrating JWT and Refresh Token usage with testing

Hands-On Testing Scenarios 🔍

Throughout the course, you'll learn to test a variety of functionalities:

• Testing Routes and Handlers: Understand how to ensure your web routes and handlers work as expected.
• Database Operations: Learn to test interactions with databases using the Repository pattern.
• Middleware Testing: Secure your applications by writing tests for your middleware.
