Free ISTQB ISTQB-CTFL Practice Exam with Questions & Answers | Set: 5

Comprehensive and Detailed In-Depth Explanation:

Test automation improves efficiency and accuracy, but it does NOT eliminate manual testing (D).

(A) is correct because automation speeds up execution.

(B) is correct as automated tests produce consistent and unbiased results.

(C) is correct because automation reduces human errors in repetitive tests.

However, manual testing remains essential for exploratory testing, usability testing, and complex test scenarios.

There are two main approaches to test estimation:

Expert-based approach:

The Wideband Delphi estimation technique is an example of this approach.

Involves consulting expert​ (ISTQB not-for-profit association)​ate testing efforts.

This technique gathers estimates from multiple experts, discusses their differences, and achieves consensus.

Metrics-based approach:

Relies on historical data and metrics to predict future testing efforts.

According to the ISTQB Certified Tester Foundation Level (CTFL) v4.0 syllabus, the expert-based approach relies on experts' experience and knowledge, which aligns with the Wideband Delphi technique【6†source】.

Matching the main review process activities with the specific review activities, we see that planning includes estimating effort and timeframe (2) and selecting people to participate (4). Initiating a review involves distributing work products and other material (5). Issue communication and analysis includes evaluating the review findings (6). Fixing and reporting would entail creating defect reports (1) and recording the updated status of defects (3).

According to the decision table in the image, a Preferred Guest Card holder with a Silver room is eligible for an upgrade to Gold Luxury (YES), while a non-Preferred Guest Card holder, regardless of room type, is not eligible for any upgrade (NO). Therefore, Customer A (a Preferred Guest Card holder with a Silver room) would be offered an upgrade to Gold Luxury, and Customer B (a non-Preferred Guest Card holder with a Platinum room) would not be offered any upgrade. References = The answer is derived directly from the decision table provided in the image; specific ISTQB Certified Tester Foundation Level (CTFL) v4.0 documents are not referenced.

Comprehensive and Detailed In-Depth Explanation:

Branch testing is a structural testing technique that ensures each branch (decision point) in the control flow is executed at least once. The goal is to measure branch coverage, which is the number of branches exercised divided by the total number of branches.

(A) describes statement testing, not branch testing.

(B) and (D) introduce confusion between decisions and statements, whereas branch testing focuses on control flow branches.

In simple terms, branch testing checks that all possible decision outcomes (true/false) are executed, whereas statement testing only ensures that each line of code is executed.

State transition testing is a black-box testing technique where test cases are designed to cover states and transitions of a state machine.

Given the state model with the following transitions:

PLACED -> IN PRODUCTION

IN PRODUCTION -> CANCELLED

IN PRODUCTION -> SHIPPED

SHIPPED -> INVOICED

INVOICED -> CANCELLED

CANCELLED -> PLACED

To cover all transitions at least once, we need to create a sequence that covers all six transitions.

Option A: IN PRODUCTION -> CANCELLED -> PLACED -> IN PRODUCTION -> CANCELLED -> PLACED

- Misses SHIPPED -> INVOICED and INVOICED -> CANCELLED transitions.

Option B: IN PRODUCTION -> SHIPPED -> INVOICED -> CANCELLED -> PLACED -> IN PRODUCTION

- Covers all transitions.

Option C: PLACED -> IN PRODUCTION -> SHIPPED -> CANCELLED ​ (ISTQB not-for-profit association)​​ (Udemy)​sses INVOICED -> CANCELLED transition.

Option D: PLACED -> CANCELLED -> PLACED -> CANCELLED -> PLACED -> IN PRODUCTION -> CANCELLED

- Misses SHIPPED -> INVOICED and INVOICED -> CANCELLED transitions.

Given these, Option B covers all the transitions【6†source】【9†source】.
