Error Guessing

What is Error Guessing?

Error Guessing is an informal testing technique where testers rely on their experience, intuition, and knowledge of common mistakes to identify potential errors in software. It involves guessing where defects might occur based on past experience and testing the software accordingly.

Purpose of Error Guessing

The main purpose of Error Guessing is to uncover defects that may not be found through formal test cases or structured testing methods. Testers use their judgment to predict and pinpoint areas where errors are likely to occur.

How Does it Work?

In Error Guessing, testers apply their knowledge of the application, domain, and typical software bugs to anticipate potential defects. They then design tests specifically aimed at uncovering these anticipated issues, often focusing on critical and high-risk areas.

Benefits

Error Guessing complements formal testing methods by uncovering defects that may be missed by systematic testing approaches alone. It leverages testers' expertise and intuition to identify critical issues early in the testing process.

Conclusion

Error Guessing is a valuable testing technique that enhances the overall quality of software by detecting potential defects early. By combining experience with targeted testing efforts, testers can contribute significantly to improving software reliability and user satisfaction.
