Hey All,

Today, I would let you know the complete guide to Ad Hoc Testing

What is Ad hoc Testing

Ad hoc testing can be done at any time during the software development process, but it is often used during the late stages of testing, such as during alpha and beta testing. Ad hoc testing can also be used to test specific features or areas of the software that are at high risk for defects.

To perform ad hoc testing, testers typically start by exploring the software and trying to use it in as many different ways as possible. They look for unusual behaviors, errors, and any other problems that they can find. Testers may also use their knowledge of the software’s requirements to identify potential areas for defects.

Ad hoc testing can be a very effective way to find bugs, but it is important to note that it is not a replacement for other testing techniques, such as scripted testing and unit testing. Ad hoc testing should be used in conjunction with other testing techniques to get the best results.
