The complete guide to testing javascript & node applications

🌟 Course Title: The Complete Guide to Testing JavaScript & Node Applications

🚀 Course Headline: Become Job Ready for Advanced Node.js Development by Mastering Testing from Scratch, Jest, Cypress, Mocha, and More! 🚀

Introduction: When I started learning how to test, everything looked so easy. 🧐 Assert 2 + 2 = 4 ? Sure, it seemed like a piece of cake on paper. But when I was faced with a real-world application, the reality was terrifying. I couldn't keep up at my job, and it was downright depressing. I didn't understand what mocking was, nor did I grasp topics like stubbing or spying. It felt like a whole different language!

That's why I created this course. You're going to start from scratch, gaining a foundational understanding of testing concepts and terminology. We'll explore:

• Unit Testing: The backbone of your application's reliability.
• Test Runners: Your orchestra conductor in the test symphony.
• Assertion Libraries: The tools that tell you whether your code meets expectations.
• Test Suites and Organising Tests: Keeping your tests clean, maintainable, and readable.
• Running Tests: Automating your testing process for efficiency and accuracy.

The Learning Journey: We'll dive into writing unit tests for real-world functions, ensuring you understand what it feels like to test a project that behaves like the ones you'll encounter in the industry. We have a full-stack, advanced JavaScript application built with the latest features, and we'll use it as our canvas to paint our testing skills.

There will be plenty of assignments and code reviews to ensure you fully grasp what we're teaching in this course. Our hands-on approach means you'll be practicing and refining your new skills from day one.

Advanced Topics: After you've got the hang of writing basic tests, we'll delve into more advanced testing techniques, including:

• Feature / Integration Testing: Ensuring your application behaves as expected under different scenarios.
• Mocking: Simulating complex dependencies with ease.
• Spying & Stubbing: Observing and intercepting function calls to ensure correct behavior and data flow.
• Asynchronous Tests: Handling the tricky world of async operations without breaking a sweat.
• Database Testing: Testing your application's interaction with databases, ensuring data integrity and reliability.
• End to End Testing: Verifying the entire flow of your application, from start to finish, for a comprehensive validation.

Test Driven JavaScript Development: We'll immerse ourselves in TEST DRIVEN JAVASCRIPT DEVELOPMENT (TDD), learning the RED, GREEN, REFACTOR TESTING CYCLE. You'll understand how to apply this methodology into your projects to build more robust and bug-free applications.

Conclusion: Are you ready to elevate your JavaScript engineering skills to an advanced level? 🚀 Enrol now in "The Complete Guide to Testing JavaScript & Node Applications" and let's embark on this transformative journey together!
