ISTQB Test Levels and Types 3

Question 1

In the V-model, what is the relationship between test levels and development phases?

Accepted Answer

Each test level corresponds to a development phase on the opposite side of the V

Answer

Test levels replace development phases to save time

Answer

Only system testing and unit testing exist in the V-model

Answer

Test levels are entirely independent of development activities

Question 2

In integration testing, what is a 'driver'?

Accepted Answer

A replacement component that calls or invokes the component under test

Answer

A test automation tool that executes scripts

Answer

A type of specialized test data for integration scenarios

Answer

A coverage metric measuring integration completeness

Question 3

Operational acceptance testing (OAT) primarily focuses on:

Accepted Answer

Validating operational readiness including backup, recovery, and maintenance procedures

Answer

Verifying that all functional requirements are met

Answer

Testing user interface design and accessibility

Answer

Checking cross-browser and cross-platform compatibility

Question 4

What is the purpose of 'impact analysis' in maintenance testing?

Accepted Answer

Identifying which parts of the system are affected by a change to scope regression testing

Answer

Analyzing the business impact of detected defects

Answer

Measuring how much testing effort a change will require

Answer

Assessing the impact of testing delays on release schedules

Question 5

How does contract acceptance testing differ from user acceptance testing (UAT)?

Accepted Answer

Contract acceptance testing verifies compliance with contractual specifications; UAT validates against user needs

Answer

Contract acceptance testing is performed by the development team; UAT is performed by users

Answer

Contract acceptance testing only covers non-functional requirements

Answer

Contract acceptance testing always precedes system testing

Question 6

Which statement about non-functional testing is MOST accurate according to ISTQB?

Accepted Answer

Non-functional testing evaluates 'how well' the system performs, covering qualities like speed, security, and usability

Answer

Non-functional testing can only begin after all functional testing is complete

Answer

Non-functional testing is always less important than functional testing

Answer

Non-functional testing only applies at the system test level

Question 7

In ISTQB terminology, what distinguishes alpha testing from beta testing?

Accepted Answer

Alpha testing is conducted at the developer's site; beta testing is conducted at customer sites or in the field

Answer

Alpha testing is done by developers; beta testing is done by independent testers

Answer

Alpha testing focuses on functional requirements; beta testing focuses on performance

Answer

Alpha testing uses white-box techniques; beta testing uses black-box techniques
