What is Testing?

Software testing is a process of evaluating the functionality of a software application to ensure that it meets the specified requirements and delivers the desired results. Testing is an essential part of the software development life cycle and helps in identifying defects or errors in the software.

There are various types of testing, including:

• Unit testing - Testing individual units or components of the software to ensure they function correctly.
• Integration testing - Testing the interactions between different units or components to ensure they work together as expected.
• System testing - Testing the entire system as a whole to validate that it meets the specified requirements.
• Acceptance testing - Testing the software from the end-user's perspective to determine if it meets their needs and requirements.

Testing can be performed manually or automated, depending on the requirements and resources available. Automated testing involves using tools and scripts to execute test cases and compare actual results with expected results.

Overall, testing plays a crucial role in ensuring the quality, reliability, and performance of software applications before they are released to users.
