What is Ad-hoc Testing?

Ad-hoc Testing is a software testing approach where testing is performed informally and spontaneously without predefined test cases.

Testers conduct Ad-hoc Testing by exploring the software randomly, without a specific plan. It is used to uncover defects that traditional testing methods may miss, making it a form of Exploratory Testing.

For instance, Ad-hoc Testing can come in handy for quick feature checks by developers or for assessing how the application behaves under unique conditions not covered in formal test cases.

This approach enables testers to unearth unexpected issues, logic errors, and usability problems that might go unnoticed in regular testing. It encourages a fresh perspective on testing, leading to more resilient software products.
