What is the difference between functional testing and automation testing?

In the field of software testing, functional testing and automation testing are two different concepts that serve distinct purposes.

Functional Testing:

Functional testing is a manual testing process where testers validate the functionality of an application by executing test cases against its features and components. It focuses on verifying whether the software behaves as expected and meets the requirements specified in the functional specifications.

Automation Testing:

Automation testing involves using specialized tools and scripts to automate the execution of test cases. It is utilized to increase test efficiency, repeatability, and accuracy. Automation testing is beneficial for executing repetitive and time-consuming tests, regression testing, and load testing.

Differences:

• Functional testing is manual, while automation testing is automated.
• Functional testing requires human intervention to execute test cases, while automation testing relies on tools and scripts.
• Automation testing is ideal for repetitive and large-scale testing tasks, while functional testing is suitable for exploratory testing and usability testing.
• Functional testing is more flexible in adapting to changes in software requirements, while automation testing requires maintenance of test scripts.

Both functional testing and automation testing play crucial roles in ensuring the quality and reliability of software applications.
