What is the use of Error Guessing?

In software testing error guessing is a method in which experience and skill play an important role. As here possible bugs and defects are guessed in the areas where formal testing would not work. That’s why it is also called experience-based testing which has no specific method of testing. This is not a formal way of performing testing still it has importance as it sometimes solves many unresolved issues also.

• Determine Which Areas Are Ambiguous: Error guessing is a technique used by testers to find unclear or poorly specified software areas that might not have clear specifications. Testers can highlight areas of the application that need more explanation or elaboration in the requirements by estimating with confidence.
• Experience-Based Testing: Testers use their expertise and understanding of typical software dangers to estimate possible flaws. This method works especially well for complicated or inadequately documented systems when experience is essential for identifying flaws.
• Testing Based on Risk: By enabling testers to concentrate on software components that pose a high risk, it is consistent with a risk-based testing methodology. Based on their assessment of regions where flaws have a higher chance of affecting the system, testers prioritize their testing efforts.
• Early Error Identification: Early defect detection during testing is made possible by error guessing. By addressing faults at an early stage, testers can contribute to the overall quality of the product by identifying potential issues before the execution of formal test cases.

Software application is a part of our daily life. May be on a laptop or maybe on our mobile phone, or it may be any digital device/interface our day starts with the use of various software applications and also ends with the use of various software applications. That’s why software companies are also trying their best to develop good quality error-free software applications for the users.

So when a company develops any software application software testing plays a major role in that. Testers not only test the product with a set of specified test cases they also test the software by coming out of the testing documents. There the term error guessing comes which is not specified in any testing instruction manual still it is still performed. So in this article, we will discuss that error then error guessing, where and how it is performed. The benefits that we get by performing it. So let’s start the topic.

Actually, an error appears when there is any logical mistake in code by the developer. It’s very hard for a developer to find an error in a large system. To solve this problem Error guessing technique is used. Error guessing technique is a software technique where a test engineer guesses and tries to break the software code. Error Guessing technique is also applied to all of the other testing techniques to produce more effective and workable tests.
