Unit testing is an essential part of any software development process. It helps developers ensure the accuracy of their code and identify bugs before they become major issues. Unit testing allows developers to test individual components of their code in isolation, so they can quickly identify and address any issues before they become more complex. It also helps developers catch errors early in the development process, saving time and money. Unit testing is a great way for developers to ensure their code is running smoothly and efficiently, and it also gives them peace of mind.
