ISTQB FOUNDATION 4.0 | Tutorial 43 | Sample Questions on Chapter 4 | ISTQB Foundation Exam Questions

Summary

This tutorial video delves into the ISTQB Foundation Level certification, focusing on Chapter 4: Test Analysis and Design. It discusses experience-based test techniques, emphasizing the importance of past knowledge and intuition in creating test cases. The video also clarifies misconceptions about statement coverage, explaining that 100% coverage means every instruction has been executed at least once. Furthermore, it highlights the best practices for documenting acceptance criteria using the 'Given-When-Then' format, aiming to reduce misunderstandings and facilitate user story completion.

Takeaways

• 📘 The tutorial focuses on the ISTQB Foundation level certification, particularly Chapter 4 about Test Analysis and Design.
• 🔍 The speaker emphasizes the importance of recalling knowledge about experience-based test techniques before looking at multiple-choice options to avoid confusion.
• 🧐 Experience-based test techniques rely heavily on the tester's past experience, domain knowledge, and intuition, rather than detailed design information.
• 🚫 Option A is incorrect as it suggests test cases are created based on detailed design, which is more aligned with formal techniques like white box testing.
• 🔗 Option B is not suitable as it relates to code coverage metrics, which is different from experience-based techniques.
• 💡 Option C is the correct answer for the first question, highlighting that experience-based techniques depend on the tester's knowledge of the software and business domain.
• 🤔 The second question discusses the implications of achieving 100% statement coverage, which does not guarantee that all possible paths or combinations of inputs have been tested.
• 🛑 Option A is correct for the second question, indicating that each instruction in the code has been executed at least once, which is the essence of 100% statement coverage.
• 🔄 The third question deals with the best way to document acceptance criteria, cautioning against the use of the word 'best' due to potential conflicting answers.
• 📝 Option B is the correct answer for the third question, suggesting that acceptance criteria can be effectively documented using the 'Given-When-Then' format.
• 📑 The tutorial concludes by encouraging continuous learning and understanding of the context, inviting questions and comments for further clarification.

Q & A

What is the main focus of the tutorial in the provided transcript?

The main focus of the tutorial is on test analysis and design, specifically discussing experience-based test techniques and sample questions related to this topic from the ISTQB Foundation Level certification.

What is an experience-based test technique?

An experience-based test technique is a method that relies heavily on the tester's past experience, domain knowledge, and intuition to identify potential defects in the software.

Why is it important to recall knowledge about a topic before looking at the options in a test question?

Recalling knowledge before looking at the options helps to establish a context and prevents confusion or being misled by potentially misleading options.

What is the significance of achieving 100% statement coverage in testing?

Achieving 100% statement coverage means that every line of code has been executed at least once, which helps ensure that all possible paths through the code have been tested.

Why might option B's statement about test suites and statement coverage be misleading?

Option B might be misleading because it suggests that the number of test cases determines coverage, whereas coverage is actually about whether every statement has been executed, not the quantity of test cases.

What does option C in the second question imply about path testing?

Option C implies that every path in the code has been executed at least once, which is not always possible due to loops and the potential for infinite paths, making this statement incorrect for statement coverage.

What does the term 'exhaustive testing' refer to, and why is it impractical?

Exhaustive testing refers to testing every possible input and execution path. It is impractical because it is often impossible to test all combinations, especially in complex systems.

What is the correct answer to the question about acceptance criteria documentation in the script?

The correct answer is using the 'given-when-then' format to describe an example test condition related to a given user story.

Why are retrospectives not suitable for determining acceptance criteria?

Retrospectives are used to capture lessons learned and improve the development and testing process, not to determine how to write acceptance criteria or improve user story writing.

What is the importance of documenting acceptance criteria?

Documenting acceptance criteria is important as it serves as a completion check for a user story, ensuring that the developed feature meets the specified requirements and expectations.

Why is verbal communication not the best method for documenting acceptance criteria?

Verbal communication can lead to misunderstandings and lacks the clarity and permanence of written documentation, which is preferred for acceptance criteria to avoid confusion and ensure consistency.
