• Question 51:

  Assume that, as part of the design choices made for a TAA, 3-switch coverage is the technique that has been selected for determining which test cases have to be produced for automated model-based testing.

  Which of the following layers of the gTAA does this design choice refer to?

  A. Test generation layer
  B. Test definition layer
  C. Test execution layer
  D. Test adaptation layer
  A. Test generation layer

• Question 52:

  You are working as a TAE for a company who are re-designing their website. The new website provides information for customers and there are two minor features being developed:

  1. Request a newsletter.

  2. Ability to contact the organisation with a question or comment.

  The website must be "mobile friendly" and available on all major web browsers.

  You have been tasked to provide an automated solution for web browsers only and to concentrate on the two minor features.

  What would be a KEY challenge with automation in this context?

  A. A low level of intrusion is likely from use of existing UI elements, but depending on the solution this might be more complex than a higher level of intrusion.
  B. Because there is a high level of intrusion there may be many false alarms.
  C. Automation might not be possible on the mobile devices.
  D. The benefits of automation might not be achieved for many years due to the complexities of the SUT and automation solution.
  C. Automation might not be possible on the mobile devices.

  ---

  Explanation

  The key challenge in this context is ensuring that the automated solution is compatible with mobile devices. Since the website must be "mobile friendly," it is crucial that the automation covers the functionality on mobile platforms. However, automating tests for mobile browsers can be more complex due to the variety of devices, screen sizes, and operating systems. This complexity can make it challenging to ensure that the automation is effective across all potential user scenarios.

These resources emphasize the importance of designing automation that is adaptable to different environments and can handle the intricacies of mobile platforms.

• Question 53:

  You have just gone through a lengthy installation process with the TAS on a SUT. This installation required setting a number of configuration parameters and tuning the interface code. The TAS is now working on the SUT.

  At this point, what should you do to verify that the changes you made to the TAS are correct?

  A. Re-install the TAS on the SUT without deleting the previous version and see if any changes result.
  B. Install the TAS on another SUT to see if it will install and work well on other SUTs.
  C. Remove any intrusive tools of the TAS and test it again on the SUT.
  D. Run test scripts with known failures and verify that they now pass.
  B. Install the TAS on another SUT to see if it will install and work well on other SUTs.

• Question 54:

  Which of the following metrics could suggest, under certain condition that an automated regression test suite has NOT been updated for new functionalities added to the SUT?

  A. The ratio of comments to executable statements in the SUT code.
  B. The SUT code coverage provided by the execution of the regression test suite.
  C. The defect density in the automation code of the regression test suite.
  D. The ratio of commands to executable statements in the automation code of the regression test suite
  B. The SUT code coverage provided by the execution of the regression test suite.

  ---

  Explanation

  The SUT code coverage metric is crucial in determining whether the test suite has been updated to cover new functionalities. If the code coverage does not increase or remains the same after new functionalities are added, it suggests that the test suite has not been adequately updated to include tests for the new code. This is because code coverage measures the extent to which the source code of the program is executed when a particular test suite runs. A test suite that is not updated for new functionalities will not execute the new parts of the code, hence the code coverage will not reflect the new additions.

  References:

  The answer is verified using the ISTQB Test Automation Engineer documents and training resources, which emphasize the importance of maintaining code coverage with the evolution of the SUT to ensure that the test suite remains effective over time.

• Question 55:

  Consider a TAS that uses a keyword-driven framework. The SUT is a web application and there is a large set of keywords available for writing the automated tests that relate to highly specific user actions linked directly to the GUI of the SUT.

  The automated test written with the keywords are statically analyzed by a custom tool which highlight's repeated instances of identical sequence of keywords. The waiting mechanism implemented by the TAS for a webpage load is based on a synchronous sampling within a given timeout. The TAS allows checking a webpage load every seconds until a timeout value.

  Based only on the given information, which of the following recommendations would you provide for improving the TAS (assuming it is possible to perform all of them)?

  A. Changing the scripting approach to data-driven scripting
  B. Implementing keywords with a higher level of granularity
  C. Changing the wait mechanism to explicit hard-coded waits
  D. Establishing an error recovery process for TAS and SUT
  B. Implementing keywords with a higher level of granularity
  D. Establishing an error recovery process for TAS and SUT

  ---

  Explanation

  In a keyword-driven framework, especially when dealing with a web application, having a large set of highly specific keywords can lead to redundancy and inefficiency. Implementing keywords with a higher level of granularity can help reduce the number of repeated instances of identical sequences of keywords, as identified by the static analysis tool. This approach promotes reusability and maintainability of test scripts, making the test automation suite more robust and easier to manage. It also aligns with the principles of modularity and abstraction, which are key in test automation engineering.

  References:

  The ISTQB CT-TAE materials emphasize the importance of maintaining a manageable level of abstraction in keyword-driven frameworks to ensure that the automated tests are efficient, maintainable, and provide clear insights into the SUT's behavior.

• Question 56:

  A project plans to automate tests for a desktop application only through its command line interface. Test cases already exist in manual form, and the main challenge is connecting the automated scripts to the specific SUT interface.

  Which gTAA layer is MOST directly concerned with this challenge?

  A. Test Generation layer
  B. Test Definition layer
  C. Test Adaptation layer
  D. Configuration Management layer
  C. Test Adaptation layer

  ---

  Explanation

  Option C is correct because the Test Adaptation layer provides the specific adapters and mechanisms needed to interact with the SUT interface, in this case the command line interface.

  Option A is incorrect because the Test Generation layer is concerned with deriving or generating tests, not connecting them to the SUT.

  Option B is incorrect because the Test Definition layer focuses on specifying and implementing the tests at an abstract level.

  Option D is incorrect because configuration management supports control of artifacts and versions, but does not provide the interface connection itself.

• Question 57:

  Consider A TAS for testing a desktop application via its GUI. All the test cases of the automated test suite contain the same identical sequences of steps at the beginning (to create the necessary objects when doing a preliminary configuration of the test environment and at the end (to remove everything created -specifically for the test itself during the preliminary configuration of the test environment). All automated test cases use the same set of assertion functions from a shared library, for verifying the values in the GUI fields ( e.g text boxes).

  What is the BEST recommendation for improving the TAS?

  A. Implementing keywords with higher level of granularity
  B. Improving the architecture of the application in order to improve its testability
  C. Adopting a set of standard verification methods for use by all automated tests
  D. Implementing standard setup and teardown functions at test case level
  D. Implementing standard setup and teardown functions at test case level

  ---

  Explanation

  The best recommendation for improving the Test Automation System (TAS) in this scenario is to implement standard setup and teardown functions at the test case level. This approach promotes reusability and efficiency by allowing the same initial and final sequences of steps to be used across multiple test cases. By centralizing these sequences into common functions, any changes to the setup or teardown process only need to be made in one place, thus reducing maintenance efforts and potential for errors. Furthermore, it streamlines the execution of test cases and makes the automation framework more robust and easier to manage.

  References:

  This recommendation aligns with the ISTQB Test Automation Engineer guidelines, which advocate for the use of reusable components and functions to enhance the maintainability and scalability of the test automation architecture. The principles of designing an effective TAS include creating modular and reusable components that can be shared across different test cases, which is essential for improving the overall efficiency and reliability of the test automation efforts.

• Question 58:

  Which of the following is NOT a technical design consideration for a TAA?

  A. The number of users for the SUT
  B. Availability of interfaces for the SUT to be testable
  C. Standards and Legal requirements, e.g data privacy
  D. Data used by the SUT, e.g configuration, users
  A. The number of users for the SUT

  ---

  Explanation

  The technical design considerations for a Test Automation Architecture (TAa)- are primarily focused on the technical aspects that will influence the design and development of the test automation solution. This includes the availability of interfaces for the SUT to be testable, which is crucial for automating tests, as well as adhering to standards and legal requirements like data privacy to ensure compliance and protect sensitive information. The data used by the SUT, such as configuration data and user data, is also a key consideration as it affects how tests are designed and executed. However, the number of users for the SUT is not a technical design consideration for a TAA; it is more related to performance testing and scalability rather than the technical design of the test automation itself.

  References:

  The ISTQB Test Automation Engineer (CT-TAe)- certification materials provide detailed insights into the design, development, and maintenance of test automation solutions, covering the necessary technical considerations for a TAA.

• Question 59:

  Your company has been using a home-grown tool for test automation for a rapidly evolving web application. The testing team is technical and has been maintaining the tool, which was originally coded in C#. This tool has worked well for small

  projects, but cannot scale for the larger projects without a major re-write that will take about two years. It is also becoming outdated and does not support any mobile testing at all. You are looking for a replacement tool. Your evaluation of the tools is shown in the table below:

  Given this information, which tool should you recommend to your management?

  A. Tool 1
  B. Tool 2
  C. Tool 3
  D. Stay with the existing tool
  B. Tool 2

• Question 60:

  Your TAS has been running successfully on a Windows/GUI based SUT for some years. The SUT has undergone minimal change over the years to maintain business as usual, deploying six-monthly releases for minor enhancements and bug fixes using a waterfall lifecycle. The TAS has not changed at all during this period. The current project for the SUT will be using the Scrum methodology to deliver a more modern, competitive, user interface. It is in the release planning stage with an agreed release backlog and set of sprints outlined.

  The move from lengthy waterfall releases to shorter sprints has led you to conduct a review of the current TAS to make sure it is robust and fully optimised for the timescale challenges of the new project.

  What two steps would be BEST to undertake during the review?

  a)- Ensure that new automation code is using the same naming conventions as existing code. b)- Perform a full regression run in Sprint 1 to identify what improvements could be made to the TAS for future sprints. c)- Ensure that the TAS is using the latest libraries for the operating system. d)- Review the functions that act upon the controls for the GUI for possible consolidation. e)- Involve the test team to see what ease-of-use improvements they would like to see made to the TAS.

  A. c and d
  B. b and c
  C. a and b
  D. d and e
  D. d and e

  ---

  Explanation

  Transitioning from a waterfall to a Scrum methodology for a Windows/GUI based SUT requires the TAS to be agile and adaptable to frequent changes. The best steps to undertake during the review would be: d)- Review the functions that act upon the controls for the GUI for possible consolidation. This step is crucial because it directly addresses the adaptability of the TAS to the new user interface, ensuring that the functions are optimized for the modernized UI. e)- Involve the test team to see what ease-of-use improvements they would like to see made to the TAS. The test team's involvement is essential for identifying practical improvements from a user perspective, which can significantly enhance the efficiency and effectiveness of the TAS during the iterative sprints of the Scrum methodology.

  These steps are aligned with the ISTQB's emphasis on ensuring that the TAS is not only technically sound but also user-friendly and responsive to the needs of the test team, which is critical in an agile environment.
