Free Practice Questions for ISTQB ISTQB-CTFL Exam

Good testing practice dictates that each test level (e.g., unit testing, integration testing, system testing) should have distinct test objectives aligned with the phase of the software development lifecycle it addresses. This ensures that testing is effective and relevant at each stage. According to the ISTQB CTFL Syllabus v4.0, establishing clear test objectives that are consistent with the development phase helps in achieving specific goals and improving the overall quality of the software product​​.

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).

 A correct list of boundary values for the age input should include the minimum and maximum values of each age group (0, 12, 13, 18), as well as the values just below and above each boundary (-1, 19). Boundary value analysis is a test design technique that involves testing the values at or near the boundaries of an input domain or output range, as these values are more likely to cause errors than values in the middle. Option A satisfies this condition, as it has all six boundary values (-1, 0, 12, 13, 18, 19). Option B has two values from the same equivalence class (12 and 13), option C has only four boundary values (0, 12, 18, 19), and option D has no boundary values at all.

One of the common risks associated with test automation tools is the underestimation of the effort required to maintain test scripts. Test scripts can become outdated or broken due to changes in the application, requiring significant effort to update and maintain them. This risk is highlighted in the ISTQB CTFL syllabus under the discussion of the benefits and risks of test automation.

Rule 5 in the decision table indicates that when the object is within 5 metres of the vehicle and the sensitivity mode is switched "on", no LED is lit. This matches the conditions and actions described in the decision table provided, ensuring that only the red LED is lit when the sensitivity mode is on and the object is within 1 metre, otherwise no LED is lit .

A formal review is a type of review that follows a defined process with formal entry and exit criteria and roles and responsibilities for participants. A formal review can have various roles involved, such as manager, moderator, author, reviewer and scribe. The manager responsibilities in formal review include all except one of the following:

Planning the review (correct responsibility)

Determines if the review objectives have been met (incorrect responsibility)

Decide on the execution of reviews (correct responsibility)

Allocate time for review (correct responsibility) The responsibility of determining if the review objectives have been met belongs to the moderator role, not to the manager role. Verified References: [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus - Springer], Chapter 3, page 28-29.

Entry and exit criteria are used to determine when to start and stop testing, respectively.

Entry Criteria:

These are conditions that should be met before testing begins.

Examples:

2. The test automation tool has been installed and properly configured

4. The performance test environment has been set-up and is available

5. The user stories have proper acceptance criteria defined

Exit Criteria:

These are conditions that should be met before testing concludes.

Examples:

1. A defined level of code coverage has been achieved

3. The number of unresolved defects is within the predefined limit

6. The testing budge​ (ISTQB not-for-profit association)​ spent and the project sponsor bears the risk of not testing any further

According to the ISTQB Certified Tester Foundation Level (CTFL) v4.0 syllabus, these criteria help in effectively managing the testing process【6†source】.

Comprehensive and Detailed In-Depth Explanation:

Testing and debugging are separate but related activities. Testing executes the software to identify failures that result from defects (A). Debugging is the developer's responsibility and involves finding the cause of a failure (defect), analyzing it, and fixing the defect. The ISTQB syllabus explicitly differentiates these activities. Testing does not modify the software, whereas debugging does.
