What is the difference between bug and defect?

- A bug is getting a problem at the time of testing, where as a defect is problem that got by the customer in production time.

- A bug is a fault in a program which causes it to behave abruptly. Bugs are usually found either during unit testing done by developer of module testing by testers.

- A defect is found when the application does not conform to the requirement specification. A defect can also be found when the client or user is testing.

Difference between Defect and Failure

a. Defect: Defect is defined as a wrong requirement.
b. Failure: Variation in the result produced by the software from its expected result.

What is the difference between BUG and DEFECT?
BUG is is the issue found in the software during the Testing Lifecycle. Defect is an issue which is not found during the Testing Lifecycle. Issues found by the developers and corrected by the developer himself is DEFECT. Issues found after the production of a software are called DEFECTS. Issues found only during the testing lifecycle are called BUGS. DEFECT and BUG are both issues in an application but depends at what stage they are caught. If they are discovered during the Testing Lifecycle then they are called BUGS but if they are discovered and corrected by the developers themselves or if they are discovered after the production of the software then they are called DEFECTS.
