CTFL4 Free Practice Test

In addition to thorough testing of the requirements specification, a development team aims to involve users as early as possible in the development process, using practices such as prototyping, to ensure that the software systems being developed will meet the users' expectations. This approach is especially useful at mitigating the risks associated with one of the seven testing principles, which one?

1. A. Tests wear out
2. B. Absence-of-errors fallacy
3. C. Working software over comprehensive documentation.
4. D. Defects cluster together

Correct Answer: B
The absence-of-errors fallacy is the mistaken belief that just because a software system is free of defects, it will meet the user's needs and expectations. Involving users early through practices like prototyping helps ensure that the development team is building the right system that meets user expectations, not just a system that is defect-free. This approach aligns with the testing principle that emphasizes understanding the users' needs and ensuring the system fulfills them. This principle is explained in the ISTQB CTFL Syllabus v4.0.

You are testing the latest version of an air-traffic control system prior to production deployment using exploratory testing. After following an unusual sequence of input steps, the system crashes. After the crash, you document a defect report with the following information:
•Title: System crashes unexpectedly during input.
•Brief summary: System crashes when an unusual sequence of inputs is used.
•Version: V1.001
•Test: Exploratory testing prior to production deployment
•Priority: Urgent
•Risk: High
•References: Screenshot of crashed application What critical Information Is missing from this report?

1. A. Conclusions, recommendations, and approvals.
2. B. Change history.
3. C. Description of the defect to enable reproduction.
4. D. Status of defect

Correct Answer: C
The critical information missing from the defect report is a detailed description of the defect to enable reproduction. A clear and concise description of the steps taken to reproduce the defect is essential for developers to understand the context and to be able to replicate the issue in their environment. Without this information, it can be challenging to diagnose and fix the defect. The ISTQB CTFL syllabus emphasizes the importance of providing all necessary details in a defect report to facilitate effective communication and resolution.

Which of the following is an advantage of the whole team approach?

1. A. It helps avoid the risk of tasks associated with a user story not moving through the Agile task board at an acceptable rate during an iteration.
2. B. It helps team members understand the current status of an iteration by visualising the amount of work left to do compared to the time allotted for the iteration
3. C. It helps the whole team be more effective in test case design by requiring all team members to master all types of test techniques.
4. D. It helps team members develop better relationships with each other and make their collaboration more effective for the benefit of the project.

Correct Answer: D
The whole team approach, often advocated in Agile methodologies, emphasizes collaboration and collective responsibility among all team members. This approach enhances the relationships within the team and improves overall collaboration, which in turn benefits the project's success. According to the ISTQB CTFL Syllabus v4.0, the whole team approach fosters better communication and cooperation, leading to more effective problem-solving and higher-quality outcomes.

Exploratory testing is an experience-based test technique

1. A. Where a developer and a tester work together on the same workstation while the developer actively writes code, the tester explores the code to find defects.
2. B. That can be organised into sessions guided by test charters outlining test objectives that will guide the testers' exploration
3. C. Where a team of testers explores all possible test techniques in order to determine the most suitable combination of these techniques to apply for a test project.
4. D. That aims at finding defects by designing tests that exercise all possible combinations ofinput values and preconditions

Correct Answer: B
Exploratory testing is an experience-based test technique where testers actively engage with the software, learning about its behavior while simultaneously designing and executing tests. According to the ISTQB CTFL syllabus, exploratory testing can be structured into sessions guided by test charters, which outline the test objectives and provide direction for the testers' exploration. This method is particularly useful in situations where test documentation is limited or where rapid feedback is needed. Thus, option B correctly describes how exploratory testing can be organized.

Which two of the following statements describe the advantages provided by good traceability between the test basis and test work products?

1. A. Analyzing the impact of changes.i
2. B. A measure of code quality.ii
3. C. Accurate test estimation.i
4. D. Making testing auditabl
5. E. Select the correct Answer:
6. F. i and ii
7. G. i and iv
8. H. i and iii
9. I. ii and iii

Correct Answer: B
Good traceability between the test basis and test work products provides several advantages: i.Analyzing the impact of changes:Traceability allows for easy identification of which parts of the test work products will be affected by changes in the requirements or design, facilitating impact analysis. iv.Making testing auditable:Traceability ensures that there is a clear connection between the requirements and the test cases, which makes the testing process auditable and provides evidence that all requirements have been tested.
