Question 7

Which of the following statements is incorrect regarding the involvement of testers in the software development lifecycle (SDLC)?

A. Testers should contribute to all activities in the SDLC and participate in design discussions.

B. Testers should be involved from the beginning of the SDLC to increase understanding of design decisions and detect defects early.

C. Testers should only be involved during the testing phase.

D. Testers' involvement is essential; developers find it difficult to be objective.

Correct Answer:C
Involving testers only during the testing phase is incorrect as per the ISTQB CTFL syllabus. Effective involvement of testers is crucial throughout the entire software development lifecycle (SDLC). This includes early stages such as requirement analysis and design, which allows testers to understand the design decisions and detect defects early. Early involvement helps in better understanding the project and ensures that quality is built into the product from the beginning. Furthermore, the ISTQB syllabus emphasizes the importance of testers contributing to all activities in the SDLC, including design discussions, to enhance defect detection and prevention.

Solution:

Does this meet the goal?

A. Yes

B. No

Correct Answer:A

Question 9

Which of the following statements describes regression testing?

A. Retesting of a fixed defectI

B. Testing of an already tested programII

C. Testing of new functionality in a programI

D. Regression testing applies only to functional testingV Tests that do not nave to be repeatable, because They are only used once

E. II, IV, V

F. I, III, IV

G. II

H. I, IV

Correct Answer:C
Regression testing is the re-running of functional and non-functional tests to ensure that previously developed and tested software still performs as expected after a change1 It does not involve retesting of a fixed defect, testing of new functionality, or applying only to functional testing. Tests that are used for regression testing should be repeatable, because they are used to verify the stability of the software after each change2 References = ISTQB Certified Tester Foundation Level (CTFL) v4.0 Syllabus, Chapter 4, Section 4.2.2, Page 291; ISTQB Glossary of Testing Terms v4.0, Page 292

Question 10

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 design and implementation.

B. Tool support for static testing.

C. Tool support for test execution and logging.

D. Tool support for performance measurement and dynamic analysis.

Correct Answer:B
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.
References:ISTQB CTFL Syllabus, Section 3.1, "Static Testing."

Question 11

Testing Quadrants, as a model, is effective in aligning stakeholders within Agile teams. Which of the following examples demonstrates this?

A. Using Testing Quadrants, the test manager is able to measure and communicate test coverage to all stakeholders.

B. Using Testing Quadrants, the test manager is able to communicate potential product risk to all stakeholders.

C. Using Testing Quadrant, the test manager is able to prioritize defects by linking these to a specific type of test.

D. Using Testing Quadrants, the test manager is able to differentiate and describe the types of tests to all stakeholders.

Correct Answer:D
The Testing Quadrants model helps Agile teams by categorizing different types of tests and their purposes. This differentiation helps test managers explain the testing strategy to all stakeholders, ensuring everyone understands the scope and objectives of each test type. This model aids in planning, executing, and tracking testing activities across different quadrants, making it easier to align with stakeholders' expectations and project goals.Reference:ISTQB CTFL Syllabus V4.0, Section 5.1.7

Question 12

Which of the following statements best describe Behavior-Driven Development (BDD)?

A. A collaborative approach that allows every stakeholder to contribute to how the softwarecomponent must behave.

B. Expresses the behavior of an application with test cases written in Given When Then format.

C. Is used to develop code guided by automated test cases.

D. A psychological technique in which the team's behavior in agile teams is evaluated.

Correct Answer:A
Behavior-Driven Development (BDD) is a collaborative approach that enhances communication among project stakeholders, including developers, testers, and business analysts. It involves defining how software should behave through examples written in a common language understandable by all stakeholders, often using the Given-When-Then format.
