Exploratory Testing Knowledge 3

Question 1

Which concept best describes using known error-prone areas of a codebase to guide exploratory testing?

Accepted Answer

Risk-based test focus

Answer

Risk-based focus directs exploratory effort toward areas most likely to contain defects, such as recently changed or historically buggy modules.

Question 2

What is the 'test oracle problem' in exploratory testing?

Accepted Answer

The challenge of determining whether an observed result is correct without a definitive reference

Answer

Without a clear oracle, the tester must rely on domain knowledge, heuristics, and judgment to decide if behavior is acceptable.

Question 3

Which heuristic model uses the acronym 'SFDIPOT' to guide exploratory testing?

Accepted Answer

The San Francisco Depot Model (James Bach's heuristic)

Answer

SFDIPOT (Structure, Function, Data, Interfaces, Platform, Operations, Time) is a product element heuristic by James Bach to ensure broad coverage.

Question 4

In exploratory testing, what is 'pairing'?

Accepted Answer

Two testers working together simultaneously—one drives, one observes and takes notes

Answer

Pairing (pair testing) combines two perspectives in real time, catching more issues and building shared knowledge.

Question 5

What does 'time-boxing' provide in an exploratory testing session?

Accepted Answer

A fixed duration that creates focus and makes sessions reportable and manageable

Answer

Time-boxing (e.g., 90-minute sessions) keeps exploration focused, prevents rabbit holes, and makes effort visible to managers.
