Why is Java code unit testing important?

For decades, unit testing has been a strong technique for software quality assurance. Unit tests ensure that an application adheres to its software design standards and performs as expected. Unit tests, when done properly, reduce problems and expose them early in the development lifecycle, improve code readability, facilitate code reuse, and speed up deployment. Testable code is created through good unit tests, which enhances quality. That code will have fewer flaws, resulting in fewer bug patches and a quicker project completion. Developers can use unit tests to quickly find and remedy problems. Whenever you add new features to a piece of software, you may need to make changes to the previous design and code, which may be both costly and risky. If you apply the unit testing methodology, you may save a lot of time and make the entire process go much more quickly and smoothly.For more info- https://eiliana.com/blogitem/career-as-a-java-game-programmer-an-overview
