Excerpts from this guide's answers.

Q2. What is manual testing?

Manual testing is testing performed by a person who designs or executes checks without relying on a test script to perform the entire test flow automatically. The tester observes behavior, explores risks, and evaluates results against requirements or expectations.

Q64. What is a blocker defect?

A blocker prevents meaningful testing or a critical business activity, such as an environment that cannot start or a core workflow that cannot proceed. The label should be defined consistently within the project.
