ISQI CTAL-TAE_V2 Actual Tests : ISTQB Certified Tester Advanced Level - Test Automation Engineering CTAL-TAE (Syllabus v2.0)

A TAS is used to run on a test environment a suite of automated regression tests, written at the UI level, on different releases of a web app: all executions complete successfully, always providing correct results (i.e., producing neither false positives nor false negatives). The tests, all independent of each other, consist of executable test scripts based on the flow model pattern which has been implemented in a three-layer TAF (test scripts, business logic, core libraries) by expanding the page object model via the facade pattern. Currently the suite takes too long to run, and the test scripts are considered too long in terms of LOC (Lines of Code).
Which of the following recommendations would you provide for improving the TAS (assuming it is possible to perform all of them)?

• A. Split the suite into sub-suites and run each of them concurrently on different test environments
• B. Implement a mechanism to automatically reboot the entire web app in the event of a crash
• C. Modify the TAF so that test scripts are based on the page object model, rather than the flow model pattern
• D. Modify the architecture of the SUT to improve its testability and, if necessary, the TAA accordingly

Which of the following recommendations can help improve the maintainability of test automation code?

• A. Avoid adopting design patterns that introduce high levels of abstraction in test automation code, such as the flow model pattern
• B. Avoid using static analyzers on test automation code and other development tools, as they are designed to improve the maintainability of SUT code
• C. Use error codes in test automation code instead of exceptions (if exceptions are supported by the programming language) for error handling
• D. Avoid producing test automation code containing methods with too many levels of nesting, as deeply nested code is more difficult to understand

In a first possible implementation, the automated test scripts within a suite locate and interact with elements of a web UI indirectly through the browsers using browser-specific drivers and APIs, provided by an automated test tool used as part of the TAS. In an alternative implementation, these test scripts locate and interact with elements of the same web UI directly at the HTML level by accessing the DOM (Document Object Model) and internal JavaScript code. The first possible implementation:

• A. Has the same level of intrusion as the alternative implementation, and therefore the risk of test scripts producing false positives is the same in both cases
• B. Has a higher level of intrusion than the alternative implementation, and therefore its test scripts are less likely to produce false positives
• C. Has a lower level of intrusion than the alternative implementation, and therefore its test scripts are less likely to produce false positives
• D. Has a lower level of intrusion than the alternative implementation, and therefore its test scripts are more likely to produce false positives

Consider a TAS implemented to perform automated testing on native mobile apps at the UI level, where the TAF implements a client-server architecture. The client runs on-premise and allows creation of automated test scripts using TAF libraries to recognize and interact with the app's UI objects. The server runs in the cloud as part of a PaaS service, receiving commands from the client, translating them into actions for the mobile device, and sending the results to the client. The cloud platform hosts several mobile devices dedicated for use by this TAS. The device on which to run test scripts/test suites is specified at run time. You are currently verifying whether the test automation environment and all other TAS/TAF components work correctly. Which of the following activities would you perform to achieve your goal?

• A. Manage the infrastructure that hosts the server, including hardware, software updates, and security patches
• B. Check whether the references to the device on which the given test scripts/test suites will be executed are correctly hard-coded within these test scripts/test suites
• C. Check whether all test scripts that will be executed by the TAS as part of a given test suite have expected results
• D. Check whether the TAF libraries that the test scripts will use to recognize and interact with the app's UI objects (widgets) function as expected

Which of the following layers within the TAA contains technology-specific implementations that enable automated tests to have the execution of their logical actions result in actual interaction with the appropriate interfaces of the SUT?

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