NEW QUESTION # 11
Which sequence of stated in the answer choices is correct in accordance with the following figure depicting the life-cycle of a defect?
Answer: C
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).

NEW QUESTION # 12
Consider the following iteration planning tasks where a tester can provide value:
- Break down user stories into tasks (particularly testing tasks)
- Estimate test effort for all testing tasks
- Identify and refine functional and non-functional aspects of the test object Which ONE of the following tasks should be ADDED to the above list?
Answer: B
Explanation:
During iteration planning, testers provide input on risk analysis, testability, and the feasibility of test automation. Participating in risk analyst is (B) helps identify areas needing more extensive testing.
(A) is incorrect because the test strategy is usually set at a higher level (project or release level).
(C) is incorrect as release planning is broader than iteration planning.
(D) is incorrect since writing user stories is mainly the responsibility of the product owner, though testers contribute to defining acceptance criteria.
Risk-based test prioritization ensures testing efforts are aligned with business needs and software risks.
NEW QUESTION # 13
A requirement specifies that if the total amount of sales (TAS) made during the year by a corporate seller is
300000€ or more, the bonus that must be paid to the seller is 100% of a certain amount agreed upon at the beginning of the year. The software contains a fault as it implements this requirement with the decision "IF (TAS = 300000)" instead of "IF (TAS >= 300000)". The application of the 3-value boundary value analysis to this problem consists of the following three test cases (TAS is an integer variable):
TC1 = 299999 TC2=300000 TC3=300001
Which of the following statements is true?
Answer: B
Explanation:
The problem described involves a software implementation error in a decision statement for calculating a bonus based on the Total Amount of Sales (TAS). The requirement states that if TAS is 300,000€ or more, a bonus should be paid. However, the software incorrectly implements this with "IF (TAS = 300000)" instead of
"IF (TAS >= 300000)".
Applying Boundary Value Analysis (BVA) to this situation involves selecting test cases at the boundaries of the input domain, including just below, at, and just above the boundary conditions.
* Test Case TC1 = 299999:
* This value is just below the boundary (300,000).
* Expected Result: No bonus should be paid.
* Actual Result: No bonus paid.
* TC1 does not highlight the fault because the implemented condition "IF (TAS = 300000)" and the correct condition "IF (TAS >= 300000)" both yield the same result (no bonus).
* Test Case TC2 = 300000:
* This value is exactly at the boundary.
* Expected Result: Bonus should be paid.
* Actual Result: Bonus paid.
* TC2 does not highlight the fault because the implemented condition "IF (TAS = 300000)" and the correct condition "IF (TAS >= 300000)" both yield the same result (bonus paid).
* Test Case TC3 = 300001:
* This value is just above the boundary.
* Expected Result: Bonus should be paid.
* Actual Result: No bonus paid due to the incorrect implementation.
* TC3 highlights the fault because the implemented condition "IF (TAS = 300000)" fails to pay the bonus, whereas the correct condition "IF (TAS >= 300000)" would pay the bonus.
* BVA focuses on the edges of input ranges where errors are more likely.
* The critical values are just below, at, and just above the boundary.
Boundary Value Analysis (BVA):Verification:According to the ISTQB CTFL syllabus, BVA is an essential technique for identifying potential errors at the boundaries of input ranges. This is because developers are more likely to make mistakes at these extremes.
Therefore, TC3 (300001) is the test case that would highlight the fault in the software's implementation of the decision condition.
NEW QUESTION # 14
A typical objective of testing is to ensure that:
Answer: A
Explanation:
This answer is correct because a typical objective of testing is to ensure that a software has been tested using a combination of test techniques, such as black-box, white-box, or experience-based techniques, that are appropriate for the test objectives, test levels, and test types. Testing using a combination of test techniques can increase the effectiveness and efficiency of testing, as different techniques can target different aspects of the software quality, such as functionality, usability, performance, security, reliability, etc. Testing using a combination of test techniques can also reduce the risk of missing defects that could be detected by one technique but not by another.

NEW QUESTION # 15
Which of the following statements is true?
Answer: B
Explanation:
Failures can be caused by defects, but also by environmental conditions. A failure is an event in which the software system does not perform a required function or performs a function incorrectly, according to the expected behavior. A defect is a flaw in the software system or a deviation from the requirements or the specifications, that may cause a failure. However, not all failures are caused by defects, as some failures may be caused by environmental conditions, such as hardware malfunctions, network interruptions, power outages, incompatible configurations, etc. Environmental conditions are factors that affect the operation of the software system, but are not part of the software system itself. The other statements are false, because:
* A defect does not always produce a failure, while a bug always produces a failure. This statement is false, because a defect may or may not produce a failure, depending on the inputs, the outputs, the states, or the scenarios of the software system, and a bug is just another term for a defect, so it has the same possibility of producing a failure as a defect. For example, a defect in a rarely used feature or a hidden branch of the code may never produce a failure, while a defect in a frequently used feature or a critical path of the code may produce a failure often. A bug is not a different concept from a defect, but rather a synonym or a colloquial term for a defect, so it has the same definition and implications as a defect.
* A defect may cause a failure which, when occurring, always causes an error. This statement is false, because an error is not a consequence of a failure, but rather a cause of a defect. An error is a human action or a mistake that produces a defect in the software system, such as a typo, a logic flaw, a requirement misunderstanding, etc. An error is not observable in the software system, but rather in the human mind or the human work products, such as the code, the design, the documentation, etc. A failure is not a cause of an error, but rather a result of a defect, which is a result of an error. For example, an error in the code may cause a defect in the software system, which may cause a failure in the software behavior.
* Bugs are defects found during component testing, while failures are defects found at higher test levels.
This statement is false, because bugs and failures are not different types of defects, but rather different terms for defects and their manifestations. As mentioned before, bugs are just another word for defects, and failures are the events in which the software system does not perform as expected due to defects.
Bugs and failures can be found at any test level, not only at component testing or higher test levels. Test levels are the stages of testing that correspond to the levels of integration of the software system, such as component testing, integration testing, system testing, and acceptance testing. Defects and failures can occur and be detected at any test level, depending on the test objectives, the test basis, the test techniques, and the test environment.
