- What is Defect Cascading in Software Testing?
Defect cascading in Software testing means triggering of other defects in an application. When a defect is not identified or goes unnoticed while testing, it invokes other defects. It leads to multiple defects in the later stages and results in an increase in a number of defects in the application.
For example, if there is a defect in an accounting system related to negative taxation then the negative taxation defect affects the ledger which in turn affects other reports such as Balance Sheet, Profit & Loss etc.,

The variation between the actual results and expected results is known as a defect. If a developer finds an issue and corrects it by himself in the development phase then it’s called a defect.
- What is a Bug?
If testers find any mismatch in the application/system in testing phase then they call it as Bug.
- What is an Error?
We can’t compile or run a program due to a coding mistake in a program. If a developer unable to successfully compile or run a program then they call it as an error.
- What is a 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 a failure.
- What is Bug Severity?
Bug/Defect severity can be defined as the impact of the bug on customer’s business. It can be Critical, Major or Minor. In simple words, how much effect will be there on the system because of a particular defect.
- What is Bug Priority?
Defect priority can be defined as how soon the defect should be fixed. It gives the order in which a defect should be resolved. Developers decide which defect they should take up next based on the priority. It can be High, Medium or Low. Most of the times the priority status is set based on the customer requirement.
