ISTQB Certified Tester Foundation Level (CTFL 2018) — Question 4

Which of the following options describe the chain of events in the correct sequence?

Answer options

• A. Error, fault, failure.
• B. Fault, bug, mistake.
• C. Mistake, failure, fault.
• D. Failure, bug, error.

Correct answer: A

Explanation

The correct sequence is A: Error, fault, failure, as it reflects the progression from an error that leads to a fault and ultimately results in a failure. The other options misplace the terms or introduce irrelevant concepts, like bugs and mistakes, which do not align with the defined sequence of events.
