Question 1

What benefits do static analysis tools have over test execution tools?

Accepted Answer

A

Explanation: :

Question 2

To test a function, the programmer has to write a _________, which calls the function to be tested and passes it test data:

Accepted Answer

B

Explanation: A driver is a piece of code that calls a function or module to be tested and passes it the necessary test data. It is commonly used in bottom-up integration testing to simulate the higher-level modules that invoke the function being tested. Stubs, on the other hand, are used to simulate lower-level modules. Reference: ISTQB CTFL Syllabus V4.0, Section 4.3.1​​.

Question 3

Boundary value testing:

Accepted Answer

B

Explanation: Boundary value testing focuses on testing at the boundaries between partitions. It tests conditions on, below, and above the edges of input and output equivalence classes to identify defects that occur at the boundaries. This technique is different from equivalence partitioning, which divides input data into partitions but does not specifically target boundary conditions. Reference: ISTQB CTFL Syllabus V4.0, Section 4.2.1​​.

Question 4

In a review meeting a moderator is a person who:

Accepted Answer

B

Explanation: In a review meeting, the moderator is responsible for ensuring the meeting runs smoothly, mediating between participants, and managing time effectively. The moderator's role includes facilitating communication and making sure all participants have the opportunity to contribute. Taking minutes of the meeting is typically done by a recorder or scribe, not the moderator. Reference: ISTQB CTFL Syllabus V4.0, Section 3.2.4​​.

Question 5

Which of the following defines the expected result of a test?

Accepted Answer

A

Explanation: A test case defines the expected result of a test. The ISTQB CTFL syllabus v4.0 explains that a test case includes a set of input values, execution preconditions, expected results, and execution postconditions developed for a particular objective or test condition​​.

Question 6

Which of the following could be a reason for a failure? 1) Testing fault 2) Software fault 3) Design fault 4) Environment Fault 5) Documentation Fault

Accepted Answer

D

Explanation: Failures in software can be caused by various reasons, including testing faults, software faults, design faults, environment faults, and documentation faults. The ISTQB CTFL syllabus v4.0 discusses that these types of issues can all contribute to failures in software, highlighting the importance of thorough testing and review processes throughout the software development lifecycle​​.

Question 7

What is retesting?

Accepted Answer

D

Explanation: Retesting, also known as confirmation testing, involves executing a previously failed test case after the defect has been fixed. The objective is to ensure that the original defect has been successfully removed. This type of testing is critical in verifying that the defect fixes are effective and that the software now operates as expected under the same conditions that previously caused the failure. Reference: ISTQB CTFL Syllabus V4.0 - Section 1.4.2, Retesting

Question 8

Which of the following principles should be followed when introducing a test tool into an
organization?
(i) Assessing organizational maturity to establish whether a tool will provide expected benefits.
(ii) Requiring a quick payback on the initial investment.
(iii) Including a requirement for the tool to be easy to use without having to train unskilled testers.
(iv) Identifying and agreeing requirements before evaluating test tools.

Accepted Answer

B

Explanation: Assessing organizational maturity (i) is very important when deciding whether to introduce a test tool, as implementing a tool in an immature test organization with poor processes is unlikely to produce any benefits. A quick return on the initial investment (ii) in a test tool is rare. Having a requirement that a tool should be easy to use for untrained and unskilled testers (iii) is generally a false hope. This is comparable with expecting someone who has never driven a car to be able to drive safely and effectively. Agreeing requirements before evaluating tools (iv) is essential. Not to do so would be comparable with building and testing a system without requirements. In conclusion, (i) and (iv) are good principles to follow when introducing a tool and (ii) and (iii) are not.

Question 9

Which of the following is true of iterative development?

Accepted Answer

B

Explanation: Iterative development involves users in the testing throughout the development process. This approach allows for continuous feedback from users, ensuring that the evolving system meets user requirements and expectations. Unlike the traditional waterfall model, iterative development accommodates changes and improvements based on user feedback, making it suitable for dynamic environments like website development. Reference: ISTQB CTFL Syllabus V4.0, Section 2.1.3​​.

Question 10

A new testing tool has been selected for an organisation and a pilot project has successfully
completed. The next step is to deploy the tool within the organization.
What is a key success factor in tool deployment?

Accepted Answer

C

Explanation: Providing support for the test team using the tool is crucial for successful deployment. This includes training the test team on how to effectively use the tool, offering ongoing support to address any issues, and integrating the tool into existing processes. By ensuring that the team is well-equipped and confident in using the tool, the organization can maximize the benefits of the tool and improve overall testing efficiency​​.

Question 11

Which option is part of the ‘implementation and execution’ area of the fundamental test process?

Accepted Answer

B

Explanation: The implementation and execution phase of the fundamental test process involves the execution of the tests according to the test plan, where the main task is to compare the actual results of the test execution against the expected results. This phase ensures that the tests are carried out and the discrepancies between the actual and expected outcomes are identified and documented. This information is critical to determining whether the software behaves as intended and meets the specified requirements. Reference: ISTQB CTFL Syllabus V4.0 - Section 1.4.1, Test Activities and Tasks

Question 12

A test case starts at S1 and triggers 4 events in sequence: E1, E4, E5, E7. What will be the finishing state and the output(s) from the test case? [K3] Refer to the exhibit https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/CTFL-FOUNDATION/page_114_img_1.jpg

Accepted Answer

C

Explanation: According to the state transition table and the sequence of events, starting from state S1 and triggering events E1, E4, E5, and E7 will lead the system to state S4 with the output O4. Each event transitions the system from one state to another, producing the specified output at each step until the final state and output are reached​​.

Question 13

Which statement correctly describes debugging? [K2]

Accepted Answer

D

Explanation: Debugging is the process where developers identify, locate, and correct defects. Testers are then responsible for confirming that the correction has resolved the original defect. This separation of responsibilities ensures that defects are properly fixed and verified. Reference: ISTQB CTFL Syllabus, version 4.0, explains the roles of developers and testers in the debugging process​​.

Question 14

Functional and structural tests are alternative test types that may be used separately or together at which test level? [K1]

Accepted Answer

B

Explanation: Functional and structural tests are types of testing techniques that can be applied at various levels of testing. According to the ISTQB CTFL syllabus, functional and structural tests are not restricted to any specific test level but are applicable across all levels of testing. This includes component, integration, system, and acceptance testing. The use of both types of tests helps ensure comprehensive testing coverage, addressing both the functional requirements and the internal structure of the software product​​.

Question 15

Which of the following is a valid objective of testing? [K1]

Accepted Answer

C

Explanation: A valid objective of testing is to prevent defects. While correcting defects and locating defects in the code are part of the testing process, the primary goal is often to prevent defects by identifying issues early in the development cycle and improving the overall quality of the software. Ensuring no defects are present is an unrealistic objective, as testing can demonstrate the presence of defects but not their absence. Reference: ISTQB CTFL Syllabus, version 4.0, emphasizes the objectives of testing, including defect prevention as a key goal​​.
