What type of behaviors do tests typically assess?

Tests are designed to provide a comprehensive assessment of the system or application they are evaluating. This includes assessing both positive and negative behaviors. Positive behaviors refer to how the system should function under expected conditions, ensuring that all desired actions work as intended. Conversely, negative behaviors are equally important as they assess how the system reacts to invalid inputs or unexpected conditions, which helps identify flaws or vulnerabilities.

By evaluating both dimensions, tests can confirm that a system not only performs correctly but also handles errors gracefully and maintains integrity under stress or misuse. This holistic approach is crucial for developing robust software that can handle a variety of real-world scenarios. Recognizing and addressing both positive and negative behaviors leads to more comprehensive testing results and a more reliable end product.
