Why should you take this Testing course?

Well what's the point of building amazing, beautiful, enterprise-level applications if they don't work?

Here at ZTM we're big fans of test-driven development (TDD), which means you'll learn how to write clean code and catch bugs before they even have a chance to rear their ugly heads. We're all about that bug-free life. 🚫🐛🚫

But if you want to live that bug-free life you've got to know when and how to use the right test to get the job done! That's why this course covers everything you need to know including:

Unit Testing: Unit testing is a software testing technique where individual blocks of code, also known as "units," are tested in isolation.

The goal is to ensure that each unit works as intended and can operate effectively with other units. It is typically automated and helps catch errors early in the development process.

Unit testing is like checking each individual brick of a Lego set to make sure it's in good shape before building your Lego masterpiece!

Integration Testing: Integration testing is another software testing technique where the interaction between different components of a software application is tested.

It verifies that the various modules of the software work together seamlessly, without any conflicts or issues. Integration testing is often done after unit testing and is critical for ensuring that the software works as intended.

It's like making sure that all your Lego pieces fit together perfectly (okay that's enough Lego metaphors!).

End-to-End (E2E) Testing: End-to-end testing (or "E2E") is a software testing technique that involves testing a software application in its entirety. It verifies that the software can perform as expected in real-world scenarios and interactions.

End-to-end testing typically involves testing the software from the user's perspective, and it checks the functionality, performance, and security of the entire system.

It's like taking a new car out for a test drive before you buy it - you want to make sure that everything is working smoothly in a real-world environment.

Backend Testing: Backend testing is a software testing technique that focuses on testing the backend of a software application. It verifies the functionality of the database, the application server, and the APIs that the software uses to communicate with the backend. It's essential for ensuring that the software performs as intended and that the user experience is chef's kiss.

Backend testing is like checking the plumbing in your house. You want to make sure that all the pipes are in good condition and that water is flowing correctly throughout your home.

API Testing: API testing is a web application testing technique that verifies the functionality of the application programming interfaces (APIs) that the software uses to communicate with the backend systems.

The goal is to ensure that the APIs are working as expected and that the software can access and retrieve data from the backend.

Different Frameworks Testing: You want to make sure that the testing framework you're using is the best fit for your software and that it will help you achieve the best results.

Different frameworks testing is like trying on different shoes to see which ones fit you best.

Test Driven Development (TDD): Test-driven development is a software development technique where the tests are written before the code is written. It involves writing small, automated tests that can be run frequently, and it helps ensure that the software is reliable and easy to maintain. The goal is to ensure that the code is written to pass the tests, which helps catch errors early in the development process.

Think of it as making a plan before you start building your Lego masterpiece (okay I lied, looks like there's room for one more Lego metaphor!). You want to make sure that you have a clear idea of what you want to achieve and that you're building your software with a solid foundation, and TDD helps you do that.

Clean Code: Clean code is a software development practice that focuses on writing code that is easy to read, understand, and maintain. It involves using naming conventions, comments, and whitespace to make the code more readable, and it's essential for ensuring that the software is easy to modify, test, debug, and extend.

Having clean code is like having a clean house - everything you do becomes easier.

Bug-Free Code: Bug-free code is a software development goal where the software is free from errors or bugs that involves testing the software to ensure that it performs as expected and that it does not have any defects or issues.

The goal of bug-free code is to ensure that the software is reliable, secure, and provides a seamless user experience. After all you want to make sure that your software is functioning perfectly, without any errors or glitches, so that your users have a smooth experience, right?

What's the bottom line?

This course will push you and challenge you to gain a deeper understanding of web application testing so that you can become a top 10% Developer 💪.

And... you have nothing to lose.
