Error Guessing - (Testing Techniques)

Error guessing is a popular testing technique used to identify defects and issues in software applications. As the name suggests, this technique involves guessing at potential faults in the application based on past experience and intuition. In this tutorial, we'll discuss how to use error guessing as a testing technique in software development.

Syntax

There is no specific syntax for error guessing as a testing technique.

Example

Suppose you are testing a new e-commerce website that allows users to purchase items online. To use error guessing as a testing technique in this scenario, you might guess at potential issues based on past experience and common sense:

• Entering an invalid shipping address could result in the package being delivered to the wrong address or not being delivered at all.
• Attempting to purchase an item that is out of stock could result in the user being charged for the item without receiving it.
• Providing incorrect payment information could result in the user being unable to purchase the item.

These are just a few examples of potential issues that could be identified using error guessing as a testing technique.

Explanation

Error guessing involves using experiences, insights, intuition, and knowledge about the application to guess potential errors and defects. This testing technique is based on the premise that past errors and faults can lead to similar errors and faults in the future. Error guessing is often used in conjunction with other testing techniques, such as exploratory testing, to provide a holistic approach to finding defects in software applications.

Use

Error guessing can be used in a variety of scenarios, including:

• Testing applications where requirements may not be well-defined or documented
• Testing new or untested features
• Testing applications where source code is not available
• Testing applications where time is limited

Important Points

Here are some important points to keep in mind when using error guessing as a testing technique:

• Error guessing can be subjective and may depend on the experience and intuition of the tester.
• Error guessing is not a comprehensive testing technique and should be used in conjunction with other testing techniques.
• Testers should document and communicate any defects or issues identified through error guessing to the development team.

Summary

In this tutorial, we discussed error guessing as a testing technique in software development. We covered the syntax, example, explanation, use, and important points of using error guessing to identify defects and issues in software applications. By incorporating error guessing into your testing strategy, you can identify potential faults and issues early on in the development process and improve the overall quality of your software application.
