In this article, We will see the difference between bug and defect, What is a bug, defect, error, and failure.
What is a Bug?
A bug in software testing is a divergence from the customer's requirements, or, to put it another way, a discrepancy between the expected result and the actual result in an application or a module that is discovered by the testing team throughout the testing phase.
What is a Defect?
Defects, which are discovered during the development phase of an application's unit testing, occur when the functionality of the program does not function as the client requires. Like A flaw could be caused by entering incorrect data or by any programming error.
What is an Error?
A software engineer's slip-up, misunderstanding, or mistake is referred to as an error in software testing. Software engineers, analysts, programmers, and testers are all considered developers. For instance, a programmer can type a variable name improperly or a developer might misunderstand a design notation, both of which could result in an error. It is produced as a result of a bad login, loop, or syntax.
What is a Failure?
If the customer discovers any problems with the software after it has been completed and delivered to them, that indicates that the software has failed.

Bug Vs Defect: What's the Difference?
