Which of the following best describes error guessing?

Error guessing is a testing technique that relies on the tester's intuition and experience to anticipate possible defects in the software. When a tester uses this approach, they draw on their knowledge of the application, its components, and previous experiences with similar systems or applications. By leveraging this contextual understanding, testers can predict where defects are likely to exist, allowing them to create targeted test cases that focus on those high-risk areas.

This method is particularly useful in Agile environments where rapid iterations may not allow for extensive documentation or regression testing. Testers can make informed guesses about where issues are most likely to arise based on their familiarity with the software development process, common pitfalls, and the behavior of similar applications.

In contrast, using documented bugs to create tests looks back at known issues rather than proactively predicting new defects. Software metrics provide quantitative data that can inform testing but do not directly involve the intuitive aspect characteristic of error guessing. Executing tests randomly is not a strategic approach and lacks the insight required to uncover defects effectively. Thus, anticipating potential defects based on past experience is the most accurate depiction of error guessing.
