NEW QUESTION # 24
Which of the following statements best captures the difference between data-driven and keyword-driven test automation?
- A. Data-driven test automation extends keyword-driven automation by defining data corresponding to business processes.
- B. Data-driven test automation is more maintainable than keyword-driven test automation.
- C. Keyword-driven test automation extends data-driven automation by defining keywords corresponding to business processes.
- D. Keyword-driven test automation is easier to develop than data-driven test automation.
Answer: C
Explanation:
Keyword-driven test automation is a framework where test cases are written using keywords that represent the actions or tests to be performed on the system. This is an extension of data-driven test automation, which focuses on separating test scripts from the test data, allowing the same test script to be run with various sets of data. Keyword-driven test automation further abstracts the process by allowing tests to be written in a more human-readable form that corresponds to business processes. This approach can improve maintainability and readability of test cases, making them easier to understand and modify. It's not necessarily the case that one is more maintainable or easier to develop than the other (Options C and D); rather, they serve different purposes in test automation strategy.
NEW QUESTION # 25
You are involved in testing a system in the medical domain. Testing needs to comply with the FDA requirements and is rated as being safety critical. A product risk assessment has been performed and various mitigation actions have been identified. Reliability testing is one of the test types that needs to be performed throughout the development lifecycle.
Based on the information provided, which of the following activities would need to be addressed in the test plan?
- A. Design and execution of specific tests that evaluate the software's tolerance to faults in terms of handling unexpected input values.
- B. Testing whether the installation/de-installation can be completed.
- C. Perform a vulnerability scan.
- D. Design and execution of test cases for scalability.
Answer: A
Explanation:
In the context of safety-critical systems, particularly in the medical domain, reliability is of utmost importance. For such systems, it is crucial to ensure that the software can handle unexpected input values and continue to operate without failure. This is essential to ensure patient safety and compliance with FDA requirements. Vulnerability scans (option A) are more related to security testing, whereas scalability (option C) and installation/de-installation (option D) are important but not specifically related to the reliability and safety criticality of the system in the medical domain.
NEW QUESTION # 26
Which of the following statements about performance testing tools is NOT correct?
- A. Significant factors to consider in the implementation of performance testing tools include the flexibility of the tool to allow different operational profiles to be easily implemented, and the hardware and network bandwidth required to generate the load.
- B. Typical metrics and reports provided by performance testing tools include the number of simulated users throughout the test, and the number and type of transactions generated by the simulated users, and the arrival rate of the transactions.
- C. Performance testing tools generate a load by simulating a large number of virtual users following their designated operational profiles to generate specific volumes of input data.
- D. Performance testing tools typically drive the application by simulating user interaction at the graphical user interface level to more accurately measure response times.
Answer: D
Explanation:
The statement about performance testing tools that is NOT correct is that they typically drive the application by simulating user interaction at the graphical user interface (GUI) level to more accurately measure response times. In practice, performance testing tools often simulate user interactions at a protocol or service level rather than the GUI level. This approach allows the tools to generate a high load by simulating many virtual users, which would be challenging to achieve with GUI-level interactions due to the higher resource consumption and slower execution speed associated with GUI automation.
Performance testing tools are designed to assess the performance of a system under a particular load and are not primarily focused on the user interface. They simulate multiple users accessing the system simultaneously, which helps in identifying bottlenecks, understanding the system's behavior under load, and determining how the system scales with increasing load. The tools typically simulate user requests to the server, bypassing the GUI to directly test the backend, APIs, or other service endpoints. This method allows for more efficient and scalable testing, enabling the simulation of thousands of users without the overhead of rendering the GUI.
NEW QUESTION # 27
You have been assigned to perform a review on code provided below:
Which type of defect should you report as part of the code review?
- A. No defects should be reported, code is correct.
- B. Endless loop
- C. Unreachable code
- D. Too many nested levels
Answer: B
Explanation:
The code provided contains a potential endless loop. The loop is conditioned on the variable 'E' being less than 1 (IF E < 1), but within the loop, there is no operation that modifies the value of 'E'. Therefore, once the loop is entered, if the condition A > B holds true, the value of 'E' remains unchanged, leading to an endless loop situation. The decrement of 'A' in line 15 does not guarantee an exit condition for the loop, as it does not affect the value of 'E'. This is a control flow defect that could cause the program to hang or crash.
NEW QUESTION # 28
At which test level would reliability testing most likely be performed?
- A. System testing
- B. Component testing
- C. Functional acceptance testing
- D. Static testing
Answer: A
Explanation:
Reliability testing is aimed at verifying the software's ability to function under expected conditions for a specified period of time. It is typically conducted during system testing, where the software is tested in its entirety to ensure that all components work together as expected in an environment that closely simulates the production environment. Reliability testing is not typically associated with static testing, component testing, or functional acceptance testing, as these levels of testing do not address the overall behavior of the system over time.
NEW QUESTION # 29
Which of the following statements is TRUE regarding tools that support component testing and the build process?
- A. Component testing tools are typically specific to the programming language and may be used to automate unit testing.
- B. Component testing tools are the basis for a continuous integration environment.
- C. Component testing and build automation tools are only used by developers.
- D. Build automations tools facilitate manual testing at a low level by allowing the change of variables values during test execution.
Answer: A
Explanation:
Component testing tools, which are often specific to a programming language, are used to automate unit tests (answer C). These tools help to validate the functionality of individual components or units of code in isolation from the rest of the application. While build automation tools are indeed used by developers and are related to continuous integration (answers A and D), and they can facilitate testing at various levels (answer B), component testing tools' primary purpose is to support the testing of individual components, often through automated unit tests, which can be specific to the language in which the components are written.
NEW QUESTION # 30
Consider the pseudo code provided below:
Given the following tests, what additional test(s) (if any) would be needed in order to achieve 100% statement coverage, with the minimum number of tests?
Test 1: A = 7, B = 7, Expected output: 7
Test 2: A = 7, B = 5, Expected output: 5
- A. No additional test cases are needed to achieve 100% statement coverage.
- B. A=6, B=12, Expected output: Bingo! and A=7, B=9, Expected output: 7
- C. A=6, B=12, Expected output: Bingo!
- D. A=7, B=9, Expected output: 7
Answer: A
Explanation:
100% statement coverage means that every line of code is executed at least once during testing. Based on the provided pseudo-code and the test cases given:
Test 1 executes the MIN = B statement when A and B are equal.
Test 2 executes the MIN = A statement and skips the inner IF since B is not equal to 2*A.
All statements within the code have been executed by these two tests, hence no additional test cases are needed to achieve 100% statement coverage.
NEW QUESTION # 31
Consider the code fragment provided below:
The comment frequency of the code fragment is 13%.
To which non-functional quality characteristic does a good level of comment frequency especially contribute?
- A. Usability
- B. Portability
- C. Maintainability
- D. Performance Efficiency
Answer: C
Explanation:
The comment frequency in a code fragment relates to the number of comments in relation to the code size. A good level of comment frequency can significantly contribute to the maintainability of the software. Maintainability is a non-functional quality characteristic that refers to the ease with which a software system can be modified to correct defects, update features, improve performance or other attributes, or adapt to a changed environment. Comments in the code help developers understand the logic, purpose, and functionality of the code, which is crucial when modifications are required. This does not directly contribute to portability, usability, or performance efficiency, which are concerned with different aspects of the software's operation and user interaction.
NEW QUESTION # 32
You are working on an internet banking project. Your company is offering this product to the financial market. For each new customer, some customization will typically be needed. To make the product successful there is a strong focus during development on a reliable and maintainable architecture. To support architectural reviews, a checklist will be developed. Within the checklist specific sections will be attributed to reliability and maintainability.
Which question from the list below should you include in the maintainability section of the architectural review checklist?
- A. Will the system use n-version programming for critical components?
- B. Does the system have user-friendly error messages?
- C. Does the password protection of the system adhere to the latest regulations?
- D. Will the user interface be implemented independently from the other software modules?
Answer: D
Explanation:
In the context of an internet banking project where reliability and maintainability are emphasized, a key factor for maintainability is the modularity of the system. Implementing the user interface independently from other software modules (answer B) can significantly enhance maintainability. This is because it allows changes to be made to the user interface without impacting the underlying business logic or data access layers, making the system more adaptable to change. This kind of separation of concerns is a recognized best practice in software design for maintainability. The other options (A, C, and D) relate more to reliability and security aspects than to maintainability.
NEW QUESTION # 33
Within an embedded software project, the maintainability of the software is considered to be critical. It has been decided to use static analysis on each delivered software component.
Which of the following metrics is NOT a maintainability metric typically used with static analysis?
- A. Number of Lines of Code (LOG)
- B. Number of Function Calls
- C. Comment Frequency
- D. Mean Time Between Failures
Answer: D
Explanation:
Maintainability metrics typically used with static analysis include measures that reflect the complexity and understandability of the code, such as Number of Lines of Code (LOC), Number of Function Calls, and Comment Frequency. These metrics help in assessing how easily the software can be understood, modified, and maintained. Mean Time Between Failures (MTBF), on the other hand, is a reliability metric. It measures the time elapsed between inherent failures of a system during operation. MTBF is used to predict the system's reliability and is not directly related to the maintainability of the code. Reliability metrics like MTBF would be used in the testing phase to measure the operational reliability of the system rather than during static analysis for maintainability assessment.
NEW QUESTION # 34
A software company based in Spain that develops mobile applications expects many small updates in the future, e.g., due to changing configurations and customer feedback. The company also wants to focus on being able to change the software effectively and efficiently during initial development without introducing new defects.
Which maintainability sub-characteristic should be covered by the test approach during the initial development?
- A. Modifiability
- B. Re-usability
- C. Analysability
- D. Modularity
Answer: A
Explanation:
In the context of a software company in Spain developing mobile applications with an expectation of many small updates due to changing configurations and customer feedback, focusing on being able to change the software effectively and efficiently during initial development without introducing new defects is crucial. The maintainability sub-characteristic that should be covered by the test approach during the initial development is Modifiability.
Modifiability refers to the ease with which a software product can be modified to correct faults, improve performance or other attributes, or adapt to a changed environment. In a scenario where frequent and small updates are anticipated, ensuring that the software architecture and design support easy modification is vital. This not only aids in implementing changes more rapidly but also helps in maintaining the stability and integrity of the application, thereby preventing the introduction of new defects. The focus on modifiability ensures that the software remains responsive to customer feedback and evolving requirements without compromising on quality or performance.
NEW QUESTION # 35
Consider the pseudo code provided below regarding a customer request for cash withdrawal from an ATM.
If the customer has sufficient funds in their account
OR the customer has the credit granted
THEN the ATM machine pays out the requested amount to the customer
Which of the following test cases would be the result of applying multiple condition testing, but would NOT be the result of applying modified condition/decision testing?
- A. TC 3: Customer does not have sufficient funds. Credit has not been granted.
- B. TC 4: Customer has sufficient funds. Credit has been granted.
- C. TC 1: Customer has sufficient funds. Credit has not been granted.
- D. TC 2: Customer does not have sufficient funds. Credit has been granted.
Answer: A
Explanation:
Multiple condition testing requires each possible combination of conditions to be tested, whereas modified condition/decision testing (MC/DC) requires each condition to be shown to independently affect the outcome. In the case of the ATM withdrawal, TC 3 (Customer does not have sufficient funds and credit has not been granted) would not result in the machine paying out, which is a result of applying multiple condition testing. However, for MC/DC, this test case would not be included because it doesn't provide an independent assessment of either condition's effect on the decision since both conditions are negative and the outcome is as expected (no payout).
NEW QUESTION # 36
Below is the pseudo-code for the Win program:
The bingo program contains a data flow anomaly. Which data flow anomaly can be found in this program?
- A. Variable 'D" is defined but subsequently not used.
- B. The program does not contain any comments.
- C. It is recommended to use a variable instead of the hard-coded print results "Win" and *Loose".
- D. Variable 'A" is not assigned a value before using it.
Answer: A
Explanation:
The pseudo-code provided for the "Win" program reads in variables A, B, C, and D. However, only variables A, B, and C are used in the conditional statements to determine if the output will be "Win" or "Loose". Variable 'D' is never used after it is read, which is a classic example of a 'defined but not used' data flow anomaly. This means that while there is an instruction to read a value into variable 'D', there is no subsequent use of this variable in the program's logic or output.
NEW QUESTION # 37
The following characteristics were identified during an early product risk-assessment for a software system:
* the software system needs to manage synchronization between various processes
* microcontrollers will be used that will limit product performance
* the hardware that will be used will make use of timeslots
* the number of tasks supported in parallel by the software system is large and are often highly complex.
Based on the information provided, which of the following non-functional test types is MOST appropriate to be performed?
- A. Maintainability testing
- B. Time-behaviour testing
- C. Portability testing
- D. Security testing
Answer: B
Explanation:
The characteristics listed in the question point towards the need to manage synchronization between processes and make efficient use of limited hardware resources, such as microcontrollers and timeslots. Additionally, the complexity and concurrency of tasks highlight the importance of the software's performance over time. Time-behaviour testing is the most appropriate non-functional test type to perform in this scenario as it focuses on evaluating the timing aspects of the system, such as response times, processing times, and throughput rates. It ensures that the system meets its time-related requirements, which is critical for systems reliant on synchronization and limited by hardware performance constraints.
NEW QUESTION # 38
There are multiple activities the Technical Test Analyst performs regarding test automation. Which of the following activities is a typical test automation activity that the Technical Test Analyst will perform?
- A. Execute the test cases and analyze any failures that may occur.
- B. Decide regarding a test automation project based on a business case.
- C. Define the business process keywords and related actions.
- D. Train the Test Analyst and Business Analyst to use and supply data for the test scripts.
Answer: A
Explanation:
A Technical Test Analyst is primarily involved in the technical aspects of test preparation and execution. One of their typical activities includes the execution of test cases, particularly those that are automated, and the subsequent analysis of any test failures to identify defects and issues. This activity is more technical than defining business processes or training other analysts, and while making decisions based on a business case may be part of their role, it is not an activity directly related to test automation.
NEW QUESTION # 39
Consider the following control flow graph:
The control flow represents a software component of a car navigation system. Within the project the maximum cyclomatic complexity to be allowed is set at 5.
Which of the following statements is correct?
- A. No defect needs to be reported since the cyclomatic complexity of the component is calculated at 5.
- B. A defect needs to be reported since the cyclomatic complexity of the component is calculated at 6.
- C. No defect needs to be reported since the cyclomatic complexity of the component is calculated at 3.
- D. No defect needs to be reported since the cyclomatic complexity of the component is calculated at 4
Answer: B
Explanation:
Cyclomatic complexity is a measure of the number of linearly-independent paths through a program's source code, which is often used as a measure of the complexity of a program. The control flow graph provided represents the logic of a software component and has more than 5 nodes with decision points, indicating that the complexity would exceed the maximum allowed value of 5. The calculation for cyclomatic complexity is V(G) = E - N + 2P, where E is the number of edges, N is the number of nodes, and P is the number of connected components. In this case, the calculated cyclomatic complexity exceeds the allowed threshold, thus a defect should be reported.
NEW QUESTION # 40
You are working on project where re-use of software is an objective. You are involved in the project as a Technical Test Analyst and have been given the task to develop a checklist for code reviews.
Which question from the list below should you implement as part of the code review checklist?
- A. Are all modules, data, and interfaces uniquely identified?
- B. Are all variables defined with meaningful, consistent and clear names?
- C. Can each item be implemented with the techniques, tools, and resources available?
- D. Is it possible during acceptance testing to verity whether the item has been satisfied?
Answer: A
Explanation:
For a project where the reuse of software components is a key objective, it is essential to ensure that all modules, data, and interfaces are uniquely identified. This facilitates the tracking, maintenance, and reuse of these components in different parts of the software or in other projects. Unique identification helps in preventing confusion and conflicts that may arise due to the reuse of components that have the same name but different functionalities or interfaces.
NEW QUESTION # 41
Which of the following is a generic risk factor that should be considered by a Technical Test Analyst during a product risk analysis?
- A. Complexity of new technology.
- B. Frequency of use of the affected feature by end-users.
- C. Visibility of failure leading to negative publicity and potential image damage.
- D. High change rate of business requirements.
Answer: A
Explanation:
A Technical Test Analyst during a product risk analysis would consider the complexity of new technology as a generic risk factor. Complex new technology can introduce uncertainties and potential issues that may not be well-understood, which can increase the risk of defects. Frequency of use, visibility of failure, and high change rate of business requirements are also valid considerations, but they are more specific to particular scenarios or aspects of the product rather than the generic technological complexity which is always a concern regardless of the context.
NEW QUESTION # 42
Consider the pseudo code provided below:
Which of the following options provides a set of test cases that achieves 100% decision coverage for this code fragment, with the minimum number of test cases?
Assume that in the options, each of the three numbers in parenthesis represent the inputs for a test case, where the first number represents variable "a", the second number represents variable "b", and the third number represents variable "c".
- A. (4,5. 0); {5, 4, 5)
- B. (5. 4, 0); (3, 2, 5); (4, 5, 0)
- C. (5. 3,2)
- D. (5. 3, 2); (6, 4, 2); (5, 4, 0)
Answer: D
Explanation:
To achieve 100% decision coverage with the minimum number of test cases, we need to ensure that every branch of the decision is taken at least once. For the code provided:
The first condition (a>b) is true for the first two test cases and false for the third.
The second condition (b>c) is true for the first test case, false for the second, and does not matter for the third since the first condition is false.
Therefore, with these three test cases, we cover all possible outcomes of the decision, ensuring 100% decision coverage.
