If all the other buttons used in the program are blue, but in one window the button color used is green, most testers would recognize that inconsistency as a defect. A requirements document may indicate that an OK button will be used to confirm a change, but it may not indicate the color of the button. One common way to identify bugs used during testing is consistency. These are generally recognized using other types of information or rules of thumb. And, it may be tempting to define ‘defect’ as ‘any software behavior that is not described by the requirements document.’ However, most experienced software testers recognize that there will be defects that fall outside of the expected behavior defined by the documentation. Any place where the software is different from the specification might be a bug. The requirements documentation is a useful way to identify defects. Sometimes the specification is called an oracle because it acts as one possible source of truth. Any team member can refer to the requirements document to determine whether the software is working correctly. Requirements documents are usually written by some combination of the development team and the business stakeholders to explicitly state the business value that the software must present to the users. Testers often start looking for defects by reading a requirements document, then examining the software to determine whether it meets the requirements. One way to define ‘defects’ is to think about how testers identify them. This article will examine ways to define ‘defects’ and techniques we can use to identify them. But, how do testers really identify what’s wrong when testing a program? Are defects always incorrect behavior or can they be something unusual or something that’s not great? Recognizing defects isn’t always as straightforward as it seems, but studying how testers identify defects can help define what they are. Team members usually think of ‘defect’ as meaning something is wrong. The answer to “What is a Defect?” may seem obvious.
