Questions and Answers

In the context of software testing, what fundamentally constitutes a 'bug'?

A coding error made by a programmer during software development.
A state of the software that causes it to crash unexpectedly.
A deviation of the actual result from the expected result. (correct)
A situation where the software does not meet the exact specifications outlined in the requirements document.

Which of the following most accurately describes the relationship between 'error', 'fault', and 'failure' in software?

A 'fault' is a deviation from the expected result, caused by a 'failure' that originated from an 'error'.
The terms are interchangeable, and any one can lead to the others in a cyclical manner.
A 'failure' leads to a 'fault', which is caused by an 'error'.
An 'error' is a human action that leads to a 'fault', which can then cause a 'failure'. (correct)

When is software testing considered complete?

Upon achieving 100% test coverage.
Software testing is a continuous endeavor, and the probability exists that bugs will be missed by testers. (correct)
After all planned tests have been executed.
When the project's budget for testing is exhausted.

What is Software Testing?

Software Testing is a method to check if the software matches expected requirements and is defect-free.

Why is Testing Important?

Testing finds defects, confirms user needs, averts problems, and delivers quality products.
