ISTQB FOUNDATION 4.0 | Tutorial 22 | Sample Questions on Chapter 2 | ISTQB Foundation Mock Questions

Summary

This tutorial video delves into the ISTQB Foundation level certification, focusing on Chapter 2 about testing throughout the SDLC. It clarifies the rule that every development activity has a corresponding test activity, applicable to all SDLC models. The video also explains the 'shift left' approach in testing, emphasizing early execution of test activities. It distinguishes between regression and retesting using a user story example, highlighting the importance of confirming no side effects post-fixes through regression tests. The tutorial aims to prepare viewers for the examination with a clear understanding of testing concepts.

Takeaways

• 📚 The tutorial is focused on the ISTQB Foundation level certification, specifically Chapter 2 about testing throughout the SDLC.
• 🔍 The first question discussed emphasizes the rule that for every SDLC activity, there is a corresponding test activity, applicable to all development models, not just sequential or iterative ones.
• 🤔 The importance of recalling knowledge and understanding topics before looking at the options in exam questions is stressed to avoid being misled by tricky options.
• 🙅‍♂️ Option D in the first question is the correct answer, indicating that the rule of corresponding test activities applies to sequential, incremental, and alternative SDLC models.
• 🚫 The second question highlights the 'shift left' approach in testing, which is about preponing activities, and asks to identify what is NOT an example of this approach.
• 👀 The word 'not' in exam questions is crucial and should not be overlooked, as it can change the meaning of the question completely.
• 🛠️ Option D in the second question is the correct answer, as writing a test script before setting up the configuration management process is not an example of the shift left approach.
• 🔄 The third question involves understanding regression testing, defined as re-running tests that have previously passed to ensure no side effects have been introduced by changes.
• 📊 The table in the third question provides execution history to determine which tests are regression tests and which are retests, based on the outcomes of previous test runs.
• 🗂️ The correct answer for the third question is that only tests 5 and 7 are executed as regression tests, while the others are retests due to failures in previous runs.
• 👋 The tutorial concludes with an invitation for viewers to comment with questions and a reminder to keep learning and exploring.

Q & A

What is the significance of the rule 'for every SDLC activity, there's a corresponding test activity' in software testing?

This rule emphasizes the importance of aligning testing activities with development activities throughout the software development life cycle (SDLC). It ensures that testing is an integral part of the development process, rather than an afterthought, thereby improving the quality and reliability of the software.

In which SDLC model does the rule of corresponding test activities hold true?

The rule of having a corresponding test activity for every SDLC activity is applicable to any development model, not restricted to any particular one. It is a universal principle that ensures comprehensive testing coverage across different phases of the SDLC.

What is the 'shift left' approach in software testing?

The 'shift left' approach in software testing refers to the practice of moving testing activities earlier in the development process compared to traditional methods. This approach aims to identify and address issues earlier, reducing the overall time and cost of fixing bugs and improving the quality of the final product.

Why is it important to pay attention to the word 'not' in multiple-choice questions?

The word 'not' in multiple-choice questions often indicates a negative query, asking for what is not true or an example of a concept. Overlooking this word can lead to incorrect answers, as it inverts the meaning of the question, requiring the test-taker to identify the option that does not fit the described approach or concept.

What is the difference between retesting and regression testing?

Retesting involves executing failed test cases again after fixes have been applied to ensure that the defects have been resolved. Regression testing, on the other hand, involves re-executing test cases that have previously passed to confirm that no new defects have been introduced as a side effect of changes made to fix other issues.

Why is reviewing user requirements before formal acceptance considered a shift left approach?

Reviewing user requirements before they are formally accepted by stakeholders is a shift left approach because it involves conducting a form of static testing early in the process. This proactive step helps identify potential issues in the requirements phase, which can prevent costly changes later in the development cycle.

How does writing a component test before the corresponding code is written exemplify the shift left approach?

Writing a component test before the corresponding code is written exemplifies the shift left approach by preparing for testing early in the development process. This allows developers to have clear expectations and guidelines for what needs to be tested, potentially leading to better code quality and easier identification of issues.

Why is executing a performance efficiency test during component testing considered a shift left approach?

Executing a performance efficiency test during component testing is considered a shift left approach because it involves assessing performance aspects earlier than traditionally done, which is usually at the system testing level. By doing so, potential performance issues can be identified and addressed earlier, reducing the risk of late-cycle surprises.

What does the option D in the second question imply about the shift left approach?

Option D, which states 'writing a test script before setting up the configuration management process,' implies that this action is not an example of the shift left approach. This is because it does not involve preponing testing activities but rather follows a more traditional sequence of development and testing.

How can understanding the definitions of retesting and regression testing help in identifying which tests are executed as regression tests?

Understanding the definitions helps in distinguishing between retesting, which is about verifying fixes for previously failed tests, and regression testing, which is about ensuring that previously passed tests still function correctly after changes have been made. This understanding is crucial for identifying which tests are executed as regression tests, as it focuses on the intent behind each test execution.
