Introduction to unit tests
Unit testing is a software development process in which the smallest functionality of the application is tested and examined to check whether it works as expected or not. A unit is the smallest part of any application. Every test code written for a unit of an application is independent of each other. The goal of unit testing itself is to perform an individual tests and make sure that each piece is correct.
Convention for writing unit tests
If you follow certain guidelines and principles while writing unit tests, it makes your code maintainable and readable. The following are a few techniques that we can use while writing unit tests for any application:
- Unit testing should be carried out in small units—for a single class or a method.
- Unit testing should be carried out in isolation, meaning that a unit test should not be dependent on any other classes or methods, which is achieved by mocking such dependencies.
- Since unit testing is done in smaller parts, these should...
