What is the difference between manual testing and automated testing?

Manual testing is the process of executing test cases manually without the use of any automation tools. It involves validating the functionality of the application by human intervention. On the other hand, automated testing involves using automation tools to run pre-scripted tests on the software or application. This method of testing is faster, more reliable, and efficient compared to manual testing.

When would you choose to use each method in a project?

Manual testing is suitable for scenarios where the test cases are ad-hoc, exploratory, or require human judgment. It is ideal for scenarios where the test cases change frequently or when the application's user interface needs to be evaluated. On the other hand, automated testing is preferred for repetitive test cases, regression testing, load testing, and scenarios requiring multiple data sets. Automated testing is recommended when the project has a long lifespan or requires frequent testing to ensure the stability of the application.
