What is Error Guessing ?

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

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

An error appears when the developer makes any logical mistake in the code. It takes a lot of work for a developer to find an error in an extensive system. To solve this problem, the Error guessing technique is used. This technique is a software technique where a test engineer guesses and tries to break the software code. This technique is also applied to all other testing techniques to produce more effective and workable tests.

What is the use of Error Guessing?

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

Where or how to use it?

Error guessing in the Software Testing approach is a sort of black box testing technique, and error guessing is best used as a part of the conditions where other black box testing techniques are performed; for instance, boundary value analysis and equivalence split are not prepared to cover all of the condition which is slanted to Error in the application.

Advantages and Disadvantages of Error Guessing Technique :

Advantages :

effective when used with other testing approaches.

helpful to solve some complex and problematic areas of application.

It identifies errors that may need to be identified through other formal testing techniques.

It helps in reducing testing times.

Disadvantages :

Only capable and skilled tests can be performed.

Dependent on testers’ experience and skills.

Fails to provide a guarantee of the quality standard of the application.

There are more efficient ways of error detection as compared to effort.

Drawbacks of Error Guessing Technique:

I don’t think the software has reached the expected quality.

Provide only partial coverage of an application.

This is a Test design technique where the experience of a tester is used to find the components of software where defects might be present.

It is mostly done by experienced testers who can use their past experience to find defects in software.

Error guessing has no rules for testing, it only uses the testers previous skills.

In error guessing testers can think of situations where software will fail. For example:

  1. Division by zero
  2. Pressing submit button on form without filling any entries.
  3. Entering wring data in the fields and checking software behavior.
