    • Specification-based Testing

    • Error Guessing

    • Structure-Based Testing

    • Mutation Analysis

    Correct Answer
    A. Error Guessing
    Explanation
    Error Guessing is a test design technique where testers use their knowledge and experience to anticipate and guess what defects might be present in the item under test. This technique does not rely on formal specifications or structured approaches, but rather on the intuition and creativity of the testers. They try to identify potential errors or defects based on their understanding of the system, its components, and their past experiences with similar systems. Error Guessing is a valuable technique for uncovering defects that might not be easily identified through other formal testing methods.

    Exploratory Testing is a test technique based on the following Idea: Select one:

    • Learn, design tests, and execute tests simultaneously

    • Try something, anything, and see what happens

    • Type randomly on the keyboard to force errors

    • Identify test criteria and develop test cases as early as possible

    Correct Answer
    A. Learn, design tests, and execute tests simultaneously
    Explanation
    Exploratory Testing is a test technique where testers learn, design tests, and execute tests simultaneously. This means that instead of following a predefined test plan, testers explore the software application by trying different scenarios and observing the outcomes. This approach allows testers to uncover unexpected defects and gain a deeper understanding of the system under test. By learning, designing tests, and executing tests simultaneously, testers can adapt their testing approach in real-time based on their findings, making it an effective technique for finding defects in complex and dynamic systems.

    Code coverage goals should usually be based on: Select one:

    • Program complexity and the skills of the developer

    • Program complexity and the risk of failure

    • The time available for testing

    • Program complexity and the skills of the tester

    Correct Answer
    A. Program complexity and the risk of failure
    Explanation
    Code coverage goals should usually be based on program complexity and the risk of failure. This is because code coverage measures how much of the code is being tested, and it is important to prioritize testing efforts based on the complexity of the program and the potential risks or failures that could occur. By focusing on areas of the code that are more complex or have a higher risk of failure, developers and testers can ensure that they are allocating their testing resources effectively and efficiently.

    Rate this question:

  • 7. 

    Which statement is correct? Select one:

    • 100% statement coverage always guarantees 100% path coverage

    • 100% decision or branch coverage always guarantees 100% statement coverage

    • If a program implements loops, the number of test cases needed to achieve 100% statement coverage is essentially infinite

    • The number of tests to achieve 100% path coverage will always be more than the number to achieve 100% statement coverage

    Correct Answer
    A. 100% decision or branch coverage always guarantees 100% statement coverage
    Explanation
    100% decision or branch coverage always guarantees 100% statement coverage because every decision or branch in a program corresponds to at least one statement. Therefore, if all decisions or branches are covered, all statements will also be covered. However, the reverse is not necessarily true, as there may be statements that are not associated with any decision or branch.

    Rate this question:

  • 8. 

    In structure-based testing a number of levels of coverage are define() Which is the correct ordering from the least comprehensive to the most comprehensive? Select one:

    • 100% path coverage, 100% multiple condition coverage, 100% statement coverage, 100% decision/branch coverage

    • 100% statement coverage, 100% condition coverage, 100% conformance coverage, 100% path coverage

    • 100% statement coverage, 100% decision/branch coverage, 100% condition coverage, 100% path coverage

    • 100% statement coverage, 100% path coverage, 100% decision/branch coverage, 100% multiple condition coverage

    Correct Answer
    A. 100% statement coverage, 100% decision/branch coverage, 100% condition coverage, 100% path coverage
    Explanation
    The correct ordering from the least comprehensive to the most comprehensive is as follows: 100% statement coverage, 100% decision/branch coverage, 100% condition coverage, 100% path coverage. This means that statement coverage is the least comprehensive, as it only ensures that every statement in the code has been executed at least once. Decision/branch coverage is more comprehensive as it ensures that every decision or branch in the code has been executed at least once. Condition coverage is even more comprehensive as it ensures that every condition in the code has been evaluated to both true and false at least once. Finally, path coverage is the most comprehensive as it ensures that every possible path through the code has been executed at least once.

    Rate this question:

  • 9. 

    Which of these statements is true? Select one:

    • 100% path coverage from testing does not guarantee sufficient testing of a component

    • 100% path coverage is less comprehensive than 100% branch coverage

    • 100% path coverage will find most or all defects in a component

    • All of the above

    Correct Answer
    A. 100% path coverage from testing does not guarantee sufficient testing of a component
    Explanation
    100% path coverage from testing does not guarantee sufficient testing of a component. This means that even if all possible paths in the code have been tested, there may still be other aspects of the component that have not been adequately tested. Path coverage only ensures that each possible path has been executed at least once, but it does not guarantee that all possible inputs, conditions, or scenarios have been tested. Therefore, it is possible for defects to remain undetected even with 100% path coverage.

    A. Reviewing requirements specification for ambiguity
    Explanation
    Reviewing requirements specification for ambiguity is a static testing technique because it involves analyzing the requirements documentation to identify any unclear or ambiguous statements. This technique helps to ensure that the requirements are clear, consistent, and free from any potential misunderstandings. By reviewing the requirements specification, potential issues can be identified and addressed early in the development process, reducing the risk of misunderstandings and costly rework later on.

    Rate this question:

  • 11. 

    Static Analysis of program source code often can identify: Select one:

    • All defects before the code is executed

    • Who developed and tested the code

    • Process improvement opportunities

    • The same defects as dynamic testing

    Correct Answer
    A. Process improvement opportunities
    Explanation
    Static analysis of program source code can often identify process improvement opportunities. This is because static analysis involves analyzing the code without executing it, which allows for the detection of potential issues, inefficiencies, and areas for improvement in the development process itself. By analyzing the code, developers can identify patterns, coding standards violations, code smells, and other indicators that can be used to enhance the overall development process and make it more efficient and effective. It helps in identifying areas where the development team can improve their coding practices, enhance code quality, and reduce the likelihood of defects in the future.

    Correct Answer
    A. Re-testing
    Explanation
    Re-testing refers to the process of rerunning tests on a system to ensure that any identified defects or issues have been properly fixed. It involves executing the same tests that were previously run to verify that the system is now functioning as expected. This is different from regression testing, which focuses on testing the unchanged parts of the system to ensure that the modifications or fixes have not introduced any new issues. Confidence testing and change testing are not the correct terms to describe this process.

    Which of the following are triggers for maintenance testing? 1. The period of time since last regression testing a system 2. New operating system installations 3. Changes in corporate policies and government regulations 4. Converting a legacy system to a software package 5. Developing a new software application Select one:

    • 2, 3, 4, and 5

    • 1, 2, 3, and 4

    • 2, 3, and 4

    • 2, 3, and 5

    Correct Answer
    A. 2, 3, and 4
    Explanation
    Maintenance testing is performed to ensure that a system or software remains functional and meets the changing requirements. Triggers for maintenance testing include new operating system installations (2), changes in corporate policies and government regulations (3), and converting a legacy system to a software package (4). These factors may impact the functionality and performance of the system, requiring testing to ensure that it continues to work as intended. Developing a new software application (5) is not specifically mentioned as a trigger for maintenance testing, so it is not included in the answer. The period of time since last regression testing a system (1) is not mentioned as a trigger for maintenance testing either.

    Regression testing means: Select one:

    • Testing of a previously tested program to ensure that defects have not been introduced or uncovered due to program modifications

    • Going back and re-executing a previous test level when defects are found() For example, testing the design when coding errors are found()

    • Testing with respect to user needs, requirements, and business processes to determine whether the system meets its acceptance criteria

    • Testing to determine the system's or component's compliance to standards, regulations, or conventions

    Correct Answer
    A. Testing of a previously tested program to ensure that defects have not been introduced or uncovered due to program modifications
    Explanation
    Regression testing refers to the process of retesting a previously tested program to ensure that any modifications or changes made to the program have not introduced any new defects or uncovered any existing defects. This type of testing is crucial in ensuring that the program continues to function correctly after any changes have been made. By conducting regression testing, any potential issues or bugs can be identified and fixed before the program is deployed or released to users.

    Rate this question:

  • 39. 

    An impact analysis after maintenance to an existing system evaluates: Select one:

    • The skills and knowledge of testers to perform regression testing

    • Different test design techniques to use for re-testing after a change

    • How changes to a system might affect the unchanged areas of the system

    • How long a legacy system can remain operational and not need replacement

    Correct Answer
    A. How changes to a system might affect the unchanged areas of the system
    Explanation
    An impact analysis after maintenance to an existing system evaluates how changes to a system might affect the unchanged areas of the system. This involves examining the potential impact of the changes on the overall functionality, performance, and stability of the system. It helps identify any potential risks or issues that may arise due to the changes and allows for proper planning and mitigation strategies to be put in place. This analysis is important to ensure that the system remains reliable and functional after the maintenance activities.

    Confidence testing is also called 

    • Change testing

    • Re-testing

    • Smoke testing

    • Regression testing

    Correct Answer
    A. Smoke testing
    Explanation
    Smoke testing is a type of confidence testing that focuses on quickly identifying major defects or issues in a software application. It is performed early in the testing process to ensure that the critical functionalities of the software are working as expected before conducting more comprehensive testing. Smoke testing aims to determine if the application is stable enough for further testing or if it requires further debugging. It is typically a subset of regression testing and is used to gain confidence in the software's basic functionality.
