Unit testing is a software testing method where individual units or components of a software are tested in isolation.

• Unit testing helps in identifying bugs early in the development process

• It ensures that each unit of code is working as expected

• Unit tests are usually automated and run frequently during development

• Examples of unit testing frameworks include JUnit for Java, NUnit for .NET, and pytest for Python

Unit testing is performed by writing test cases for individual units or components of the software to ensure they work as expected.

• Write test cases for each unit or component of the software

• Execute the test cases to verify the functionality of the unit

• Check for expected outcomes and compare with actual results

• Use testing frameworks like JUnit, NUnit, or PyTest

• Automate unit tests to run them regularly during development

I have used JUnit for performing unit testing in Java projects.

• JUnit is a popular unit testing framework for Java

• It provides annotations like @Test to define test methods

• JUnit assertions like assertEquals are used to verify expected results
