ISQI ISTQB Certified Tester Foundation Level (CTFL) v4.0 Sample Questions (Q73-Q78):

NEW QUESTION # 73
What type of testing measures its effectiveness by tracking which lines of code were executed by the tests?

A. Integration testing
B. Exploratory testing
C. Structural testing
D. Acceptance testing

Answer: C

Explanation:
Structural testing is a type of testing that measures its effectiveness by tracking which lines of code were executed by the tests. Structural testing, also known as white-box testing or glass-box testing, is based on the internal structure, design, or implementation of the software. Structural testing aims to verify that the software meets the specified quality attributes, such as performance, security, reliability, or maintainability, by exercising the code paths, branches, statements, conditions, or data flows. Structural testing uses various coverage metrics, such as function coverage, line coverage, branch coverage, or statement coverage, to determine how much of the code has been tested and to identify any untested or unreachable parts of the code.
Structural testing can be applied at any level of testing, such as unit testing, integration testing, system testing, or acceptance testing, but it is more commonly used at lower levels, where the testers have access to the source code.
The other options are not correct because they are not types of testing that measure their effectiveness by tracking which lines of code were executed by the tests. Acceptance testing is a type of testing that verifies that the software meets the acceptance criteria and the user requirements. Acceptance testing is usually performed by the end-users or customers, who may not have access to the source code or the technical details of the software. Acceptance testing is more concerned with the functionality, usability, or suitability of the software, rather than its internal structure or implementation. Integration testing is a type of testing that verifies that the software components or subsystems work together as expected. Integration testing is usually performed by the developers or testers, who may use both structural and functional testing techniques to check the interfaces, interactions, or dependencies between the components or subsystems. Integration testing is more concerned with the integration logic, data flow, or communication of the software, rather than its individual lines of code. Exploratory testing is a type of testing that involves simultaneous learning, test design, and test execution. Exploratory testing is usually performed by the testers, who use their creativity, intuition, or experience to explore the software and discover any defects, risks, or opportunities for improvement. Exploratory testing is more concerned with the behavior, quality, or value of the software, rather than its internal structure or implementation.

NEW QUESTION # 74
Which sequence of stated in the answer choices is correct in accordance with the following figure depicting the life-cycle of a defect?

A. S0->S1 ->S2->S3->S5->S3->S4
B. S0->S1->S2->S3->S5->S1->S2->S3
C. S0->S1->S2->S3->S5->S1
D. S0->S1->S2~>S3->S4

Answer: A

Explanation:
According to the ISTQB Certified Tester Foundation Level (CTFL) v4.0, the life cycle of a defect typically follows a sequence from its discovery to its closure. In the provided figure, it starts with S0 (New), moves to S1 (Assigned), then to S2 (Resolved), followed by S3 (Verified). If the defect is not fixed, it can be Re-opened (S5) and goes back for verification (S3). Once verified, it is Closed (S4). References: ISTQB Certified Tester Foundation Level (CTFL) v4.0 Syllabus, Section 1.4.3, Page 17.

NEW QUESTION # 75
Which of the following statement about the shift-left approach is false?

A. The shift-left approach can only be implemented with test automation
B. The shift-left approach can involve security vulnerabilities
C. The shift-left approach can be supported by static analysis tools
D. The shift-left approach in testing is compatible with DevOps practices

Answer: A

Explanation:
The statement that the shift-left approach can only be implemented with test automation is false. The shift-left approach emphasizes early testing activities in the software development lifecycle to detect and address defects as soon as possible. While test automation can support shift-left practices, it is not the only method.
The shift-left approach can also involve practices such as static analysis, early requirement reviews, and integrating security vulnerability assessments early in the development process.

NEW QUESTION # 76
Which of the following statements about error guessing is true?

A. Error guessing is a system that adopts artificial intelligence to predict whether software components are likely to contain defects or not
B. Error guessing refers to the ability of a system or component to continue normal operation despite the presence of erroneous inputs
C. Experienced testers, when applying error guessing, rely on the use of a high-level list of what needs to be tested as a guide to find defects
D. Experienced testers, when applying error guessing technique, can anticipate where errors, defects and failures have occurred and target their tests at those issues

Answer: D

Explanation:
This answer is correct because error guessing is a test design technique where the experience and intuition of the tester are used to anticipate where errors, defects and failures have occurred or are likely to occur, and to design test cases to expose them. Error guessing can be based on factors such as the complexity of the system or component, the known or suspected weaknesses of the system or component, the previous history of defects, or the common types of errors in the domain or technology. Error guessing can be used as a complementary technique to other more systematic or formal techniques, or when there is insufficient information or time to apply them.

NEW QUESTION # 77
Consider the following examples of risks identified in different software development projects:
[I]. The contrast color ratio for both normal text and large text of a website does not comply with the applicable accessibility guidelines, making it difficult for many users to read the content on the pages
[II]. A development vendor fails to deliver their software system on time, causing significant delays to system integration testing activities that have been planned as part of a development project for a system of systems
[III]. People in the test team do not have sufficient skills to automate tests at the test levels required by the test automation strategy which does not allow production of an effective regression test suite
[IV]. In a web application, data from untrusted sources is not subject to proper input validation, making the application vulnerable to several security attacks Which of the following statements is true?

A. [II], [III] and [IV] are product risks; [I] is a project risk
B. [I] and [III] are product risks; [II] and [IV] are project risks
C. [I] and [IV] are product risks. [II] and [III] are project risks
D. [IV] is a product risk; [I]. [II] and [III] are project risks

Answer: C

Explanation:
This answer is correct because product risks are risks that affect the quality of the software product, such as defects, failures, or non-compliance with requirements or standards. Project risks are risks that affect the project's schedule, budget, resources, or scope, such as delays, cost overruns, skill gaps, or scope changes. In this case, [I] and [IV] are product risks, as they relate to the accessibility and security of the software product, which are quality attributes. [II] and [III] are project risks, as they relate to the delivery time and the test automation skills of the test team, which are project factors.
