We will develop a banking application using Spring Boot. This course will help you learn how to build an application by testing various problems that arise during development using JUnit.

Even if you create the same function, the code of a junior developer who has just learned JavaScript syntax and that of an experienced senior developer will be quite different. Of course, even if the results are the same. The reason the latter's code is recognized is because of its well-designed structure and scalability to respond to changes. This lecture will learn about how to create such good code.

In this course, you will learn NodeJS, which allows you to develop backends using the Javascript language, and develop API servers using NodeJS using the test-driven development (TDD) method. You will also understand the basic principles of ExpressJS, a representative web framework for NodeJS, and learn how to develop REST APIs used in mobile and web services.

Learn how to build web applications with TDD using Spring Boot. You will learn how to maintain developer productivity and build reliable web applications with TDD.

This course covers essential content that C# application developers with 0.5 to 3 years of experience must know.

This is a job-oriented QA practical course for beginners preparing for QA employment, where you will complete test cases and checklists used directly in the field by designing and performing tests yourself using real service examples.

Are you hesitant about writing test code? Experience the A to Z of Spring environment testing through this lecture!

This course includes demonstrations used to explain the theories and applications of lasers and optics. Learners can vividly observe and understand the fundamental phenomena of lasers.
