BCS ISTQB Certified Tester Foundation Level CTFL 4.0 Sample Questions (Q29-Q34):

NEW QUESTION # 29
A new web app aims at offering a rich user experience. As a functional tester, you have run some functional tests to verify that, before releasing the app, such app works correctly on several mobile devices, all of which are listed as supported devices within the requirements specification. These tests were performed on stable and isolated test environments where you were the only user interacting with the application. All tests passed, but in some of those tests you observed the following issue: on some mobile devices only, the response time for two web pages containing images was extremely slow.
Based only on the given information, which of the following recommendation would you follow?

A. You should not open any defect report and inform the test manager that the devices on which you observed the issue should no longer be supported so that they will be removed from the requirements specification
B. The issue is related to performance efficiency, not functionality. Thus, as a functional tester, you should not open any defect report as all the functional tests passed
C. You should not open any defect report as the problem is most likely due to poor hardware equipment on the devices where you observed the issue
D. You should open a defect report providing detailed information on which devices and by running which tests you observed the issue

Answer: D

Explanation:
As a functional tester, you should open a defect report providing detailed information on which devices and by running which tests you observed the issue. A defect report is a document that records the occurrence, nature, and status of a defect detected during testing, and provides information for further investigation and resolution. A defect report should include relevant information such as the defect summary, the defect description, the defect severity, the defect priority, the defect status, the defect origin, the defect category, the defect reproduction steps, the defect screenshots, the defect attachments, etc. Opening a defect report is a good practice for any tester who finds a defect in the software system, regardless of the type or level of testing performed. The other options are not recommended, because:
The issue is related to performance efficiency, not functionality, but that does not mean that as a functional tester, you should not open any defect report as all the functional tests passed. Performance efficiency is a quality characteristic that measures how well the software system performs its functions under stated conditions, such as the response time, the resource utilization, the throughput, etc. Performance efficiency is an important aspect of the user experience, especially for web applications that run on different devices and networks. Even if the functional tests passed, meaning that the software system met the functional requirements, the performance issue observed on some devices could still affect the user satisfaction, the usability, the reliability, and the security of the software system. Therefore, as a functional tester, you have the responsibility to report the performance issue as a defect, and provide as much information as possible to help the developers or the performance testers to investigate and resolve it.

NEW QUESTION # 30
Which of the following characterizations applies to a test tool used for the analysis of a developer's code prior to its execution?

A. Tool support for test execution and logging.
B. Tool support for test design and implementation.
C. Tool support for static testing.
D. Tool support for performance measurement and dynamic analysis.

Answer: C

Explanation:
A test tool used for the analysis of a developer's code prior to its execution falls under the category of static testing tools. Static testing involves examining the code and documentation without executing the code. These tools are used to perform static analysis, which helps in identifying potential defects and code quality issues early in the development process. The ISTQB CTFL syllabus specifies that static analysis tools are essential for finding defects that do not manifest themselves during the execution of the program.

NEW QUESTION # 31
A test manager decided to skip static testing since he believes bugs can be found easily by doing dynamic testing. Was this decision right or wrong?

A. The decision was wrong. Ensuring quality mandates that static testing is performed after performing the dynamic testing.
B. The decision was right. Static testing is usually redundant if a product is planned to go through a full-cycle of dynamic testing.
C. The decision was wrong. Static testing can find defects early in the development process, reducing the overall cost of testing and development
D. The decision was right. Most of the bugs are easier to identify during the dynamic testing.

Answer: C

Explanation:
Static testing is a form of testing that does not involve executing the software or system under test. It includes activities such as reviews, inspections, walkthroughs, and analysis of documents, code, and models. Static testing can find defects early in the development process, before they become more expensive and difficult to fix in later stages. Static testing can also improve the quality of the software or system by preventing defects from being introduced in the first place. Static testing can complement dynamic testing, which involves executing the software or system under test and checking the results against expected outcomes. Dynamic testing can find defects that static testing may miss, such as performance, usability, or integration issues. However, dynamic testing alone is not sufficient to ensure quality, as it may not cover all possible scenarios, inputs, or paths. Therefore, a test manager who decides to skip static testing is making a wrong decision, as he or she is ignoring the benefits of static testing and relying solely on dynamic testing, which may not be effective or efficient enough to find and prevent defects.

NEW QUESTION # 32
Which of the following statements about statement coverage is TRUE?

A. Achieving 100% statement coverage ensures that 100% branch coverage is achieved
B. Achieving 100% statement coverage ensures that no variable within the code has been used without being initialised.
C. Achieving 80% statement coverage ensures that 80% of all executable statements within the code have been exercised.
D. Achieving 90% statement coverage ensures that 90% branch coverage is achieved.

Answer: C

Explanation:
Statement coverage measures the percentage of executable statements that have been exercised by a test suite. Achieving 80% statement coverage means that 80% of the executable code lines have been tested. This metric helps in understanding how much of the code has been covered during testing. However, it does not guarantee branch coverage, variable initialization, or detection of all possible defects. The ISTQB CTFL Syllabus v4.0 explains statement coverage as a measure of the extent to which the code has been tested, without implying other types of coverage or testing goals.

NEW QUESTION # 33
Select which of the following statements describe the key principles of software testing?
i. Testing shows the presence of defects, not their absence.
ii . Testing everything Is possible.
iii . Early testing Is more expensive and is a waste of time.
iv . Defects cluster together.
v. Testing is context dependent.
vi. Beware of the pesticide paradox.
vii . Absence of errors is a fallacy.
Select the correct answer:

A. ii, iii, iv, v and vi
B. i, iv, v, vi and vii
C. I, ii, v. vi and vii
D. iii . iv, v. vi and vii

Answer: B

Explanation:
The key principles of software testing include: i. Testing shows the presence of defects, not their absence. iv . Defects cluster together. v. Testing is context dependent. vi. Beware of the pesticide paradox. vii . Absence of errors is a fallacy. These principles highlight the importance of recognizing the limitations and context of testing, as well as the potential for repeated tests to become less effective.
