Ques. What do you mean by Defect Triage?

Ans. Defect triage is a process in which the defects are prioritized based on different factors like severity, risk, the time required to fix the bug, etc. The defect triage meeting includes the different stakeholders – the development team, testing team, project manager, BAs, etc. which decide the priority of fixing the defects.

Ques. What is the difference between Latent and Masked Defects?

Ans. A latent defect is an unidentified defect present in the current release but is not visible because the conditions in which the defect could be found have never met. These types of defects occur only when a particular event gets triggered which was concealing their presence. Whereas a masked defect is an existing defect that has not yet caused any failure because another error has masked it or prevented it from getting discovered.

Ques. What is the difference between testing and debugging?

Ans. In software testing, a requirement traceability matrix is a table that relates the high-level requirements with either detailed requirements, test plans, or test cases. RTM helps in ensuring 100% test coverage.

Another difference between the two is – testing can be done without any internal knowledge of software architecture. Whereas debugging requires knowledge of software architecture and coding.
