BCS ISTQB Certified Tester Foundation Level CTFL 4.0 認定 CTFL4 試験問題 (Q78-Q83):

質問 # 78
During component testing of a program if 100% decision coverage is achieved, which of the following coverage criteria is also guaranteed to be 100%?

A. 100% Stale transition coverage
B. 100% Equivalence class coverage
C. 100% Statement coverage
D. 100% Boundary value coverage

正解：C

解説：
Statement coverage is a structural coverage metric that measures the percentage of executable statements in the source code that are executed by a test suite1. Decision coverage is another structural coverage metric that measures the percentage of decision outcomes (such as branches or conditions) in the source code that are executed by a test suite1. Decision coverage is a stronger metric than statement coverage, because it requires that every possible outcome of each decision is tested, while statement coverage only requires that every statement is executed at least once2. Therefore, if a test suite achieves 100% decision coverage, it also implies that it achieves 100% statement coverage, because every statement in every branch or condition must have been executed. However, the converse is not true: 100% statement coverage does not guarantee 100% decision coverage, because some branches or conditions may have multiple outcomes that are not tested by the test suite2. For example, consider the following pseudocode:
if (x > 0) then print("Positive") else print("Non-positive") end if
A test suite that executes this code with x = 1 and x = -1 will achieve 100% statement coverage, because both print statements are executed. However, it will not achieve 100% decision coverage, because the condition x > 0 has only been tested with two outcomes: true and false. The third possible outcome, x = 0, has not been tested by the test suite. Therefore, the test suite may miss a potential bug or error in the condition or the branch.
The other options, such as stale transition coverage, equivalence class coverage, and boundary value coverage, are not guaranteed to be 100% by achieving 100% decision coverage. Stale transition coverage is a structural coverage metric that measures the percentage of transitions between states in a state machine that are executed by a test suite3. Equivalence class coverage is a functional coverage metric that measures the percentage of equivalence classes (or partitions) of input or output values that are tested by a test suite4. Boundary value coverage is another functional coverage metric that measures the percentage of boundary values (or extreme values) of input or output ranges that are tested by a test suite4. These metrics are independent of decision coverage, because they are based on different aspects of the system under test, such as its behavior, functionality, or specification. Therefore, achieving 100% decision coverage does not imply achieving 100% of any of these metrics, and vice versa.

質問 # 79
Confirmation testing is performed after:

A. the execution of an automated regression test suite to confirm the absence of false positives in the test results
B. a defect is fixed, and if such testing is successful then the regression tests that are relevant for such fix can be executed
C. a defect is fixed and after other tests do not find any side-effect introduced in the software as a result of such fix
D. a failed test, and aims to run that test again to confirm that the same behavior still occurs and thus appears to be reproducible

正解：B

解説：
Confirmation testing is performed after a defect is fixed, and if such testing is successful then the regression tests that are relevant for such fix can be executed. Confirmation testing, also known as re-testing, is the process of verifying that a defect has been resolved by running the test case that originally detected the defect. Confirmation testing is usually done before regression testing, which is the process of verifying that no new defects have been introduced in the software as a result of changes or fixes. Therefore, option D is the correct answer.

質問 # 80
Which one of the following is a typical entry criteria for testing?

A. Availability of testable requirements.
B. Planned tests have been executed.
C. The number of unresolved defects is within an agreed limit.
D. The number of estimated remaining defects is sufficiently low.

正解：A

解説：
A typical entry criterion for testing is the availability of testable requirements. Testable requirements provide a basis for designing and executing test cases. Without clear and testable requirements, it is challenging to determine what needs to be tested and to create effective test cases. Entry criteria ensure that the necessary preconditions are met before testing begins, which helps in conducting efficient and effective testing.
References:ISTQB CTFL Syllabus, Section 5.1.3, "Entry and Exit Criteria."

質問 # 81
Which of the following statements is true?

A. Both in Agile software development and in sequential development models, such as the V-model, test levels tend to overlap since they do not usually have defined entry and exit criteria
B. In Agile software development, the first iterations are exclusively dedicated to testing activities, as testing will be used to drive development, which will be performed in the subsequent iterations
C. In Agile software development, work product documentation tends to be lightweight and manual tests tend to be often unscripted as they are often produced using experience-based test techniques
D. Sequential development models impose the use of systematic test techniques and do not allow the use of experience-based test techniques

正解：C

解説：
This answer is correct because in Agile software development, work product documentation, such as user stories, acceptance criteria, or test cases, tends to be lightweight and concise, as the focus is on working software and frequent communication rather than comprehensive documentation. Manual tests tend to be often unscripted, as they are often produced using experience-based test techniques, such as error guessing or exploratory testing, which rely on the tester's skills, knowledge, and creativity to find defects and provide feedback. References: ISTQB Foundation Level Syllabus v4.0, Section 3.1.1.2, Section 3.2.1.2

質問 # 82
Which ONE of the following elements is TYPICALLYNOTpart of atest progress report?

A. A detailed assessment of product quality
B. Obstacles and their workarounds
C. Test metrics to show the current status of the test process
D. New or changed risks

正解：A

解説：
Comprehensive and Detailed In-Depth Explanation:Atest progress reportprovides an overview of testing activities, metrics, and identified risks. It focuses on tracking testing progress rather thanevaluating overall product quality (B), which is typically included in atest summary reportafter testing is completed.
* (A) is correctbecause obstacles (challenges) are reported to ensure test execution stays on track.
* (C) is correctas test metrics help stakeholders track execution progress.
* (D) is correctbecause new or changed risks impact test focus and priorities.
A test progress reporttracks execution and informs stakeholders about ongoing testing activities.
