Which type of testing allows testers to derive new tests from the results of previous ones?

Exploratory testing is characterized by its focus on the simultaneous learning, test design, and test execution. In this approach, testers actively explore the application and derive new tests based on their experiences, observations, and results from previous tests. This means that as they uncover new information or evaluate how the system responds under varying conditions, they can adapt their testing strategy and create additional tests that target undefined areas or uncover new risks.

The dynamic nature of exploratory testing allows for a more intuitive and flexible approach, where testers can change their testing focus based on what they learn in real time, making it particularly effective in discovering defects that might not be captured through more structured testing methods. This adaptability enhances the depth and breadth of testing, leading to potentially more effective identification of issues as the testing progresses.
