Exploratory testing is an approach where testers simultaneously design and execute tests, using their knowledge and intuition to explore the application.

Question 2

What is 'shift-left testing' in modern software development?

Accepted Answer

Moving testing activities earlier in the development lifecycle

Answer

Shift-left testing moves testing activities earlier in the SDLC so defects are caught sooner when they are cheaper to fix.

Question 3

Which metric measures the ratio of defects found during testing versus total defects found including post-release?

Accepted Answer

Defect removal efficiency

Answer

Defect Removal Efficiency (DRE) measures the percentage of defects caught during testing before the software reaches production.

Question 4

In agile testing, what are 'acceptance criteria'?

Accepted Answer

Conditions that must be satisfied for a user story to be considered complete

Answer

Acceptance criteria are specific, measurable conditions that a user story must meet to be accepted by the product owner.

Question 5
