22 | Defect, Error, Bug, Failure

Published on Aug 17, 2021 | By Tesvan team

What is a Defect

  

The variation between the actual results and expected results is known as defect. If a developer finds an issue and corrects it by himself in the development phase then it’s called a defect.

   

Bug

If testers find any mismatch in the application/system in testing phase then they call it as Bug. As I mentioned earlier, there is a contradiction in the usage of Bug and Defect. People widely say the bug is an informal name for the defect.

   

Error

We can’t compile or run a program due to coding mistake in a program. If a developer unable to successfully compile or run a program then they call it as an error.

   

Failure

Once the product is deployed and customers find any issues then they call the product as a failure product. After release, if an end user finds an issue then that particular issue is called as failure
