Manual Testing Vs Automation Testing

Difference Between Manual and Automation Testing

Software testing is a crucial phase in the software development life cycle, aimed at ensuring the quality and reliability of a software application. Two primary approaches to software testing are manual testing and automation testing. Each approach has its unique characteristics, advantages, and limitations. In this article, we’ll explore the key differences between manual and automation testing.

Manual Testing: When a tester executes the process for finding errors, defects, missing requirements manually that called the manual testing. 

Automation Testing: When a tester executes the process for finding errors, defects and missing requirements with the help of an automation tool that called automation testing.

Manual testing is mostly suitable for UI testing, ad-hoc testing and exploratory testing.Automation testing is not suitable for UI testing, ad-hoc testing and exploratory testing.
Manual testing is less reliable due to errors occurs by humanAutomation testing is more reliable due to test scripts which can be automated.
Manual testing can be done by anyone.Automation testing can be done by testers who have automation testing knowledge.
Manual testing is suitable for all types of software products.Automation testing is suitable only for stable software products. It is mainly used for regression testing.


Ultimately, the difference between manual and automation testing depends on project requirements, resource availability, and the specific testing objectives. In many cases, a combination of both approaches is employed to leverage their respective strengths.
