Manual testing and automated testing are two distinct approaches to software testing, each with its own advantages and limitations. Here are the key differences between manual testing and automated testing:

1. Definition:
Manual Testing:

Involves the execution of test cases by a human tester without the use of automation tools.
Testers manually perform test steps, analyze results, and report defects.
Automated Testing:

Involves using automation tools to execute pre-scripted tests on software applications.
Automated tests are written to perform specific actions and verify expected outcomes.
2. Execution:
Manual Testing:

Tests are executed manually by human testers who interact with the application's user interface.
Each step is performed manually, and observations are recorded.
Automated Testing:

Tests are executed by automation tools, which follow pre-defined scripts to interact with the application.
Automation tools perform actions such as clicking buttons, entering data, and verifying outcomes.
