What is the difference between positive testing and negative testing?

Positive testing is a testing technique where the system is tested with valid and expected inputs to ensure that it functions correctly and produces the desired outputs. It focuses on validating the system's ability to handle normal and expected scenarios.

On the other hand, negative testing is a testing technique where the system is tested with invalid and unexpected inputs to check its ability to handle abnormal or erroneous conditions. It aims to identify and uncover any potential flaws or vulnerabilities in the system by intentionally providing incorrect or invalid inputs.

In summary, the main difference between positive testing and negative testing lies in the type of inputs used. Positive testing focuses on valid and expected inputs, while negative testing focuses on invalid and unexpected inputs.
