Automated tests run by a TAS on a SUT can be subject to sudden bursts of messages to log during their execution. All log messages that occur during execution must be permanently stored in the corresponding test execution logs by the TAS for later analysis. If logging is not performed correctly, these bursts can reduce the execution speed of these automated tests, causing them to produce unreliable results. Which of the following solutions would you expect to be MOST useful to address this issue for TAS logging?

• A. Avoid logging the messages that occur during the specified bursts to minimize any potential performance overhead in test execution
• B. Log all the messages in memory using a circular buffer and periodically flush the buffer to the corresponding log files associated with the specific execution
• C. Use a Network Time Protocol (NTP) server to ensure that the clocks of the machines running TAS and SUT are synchronized with a common time source
• D. Log all the messages directly on the corresponding log files associated with the specific execution to ensure the permanent storage of test execution logs

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. Modify the TAF so that test scripts are based on the page object model, rather than the flow model pattern
• C. Implement a mechanism to automatically reboot the entire web app in the event of a crash
• D. Modify the architecture of the SUT to improve its testability and, if necessary, the TAA accordingly

A SUT (SUT1) is a client-server system based on a thin client. The client is primarily a display and input interface, while the server provides almost all the resources and functionality of the system. Another SUT (SUT2) is a client-server system based on a fat client that relies little on the server and provides most of the resources and functionality of the system. A given TAS is used to implement automated tests on both SUT1 and SUT2. The main objective of the TAS is to cover as many system functionalities as possible through automated tests executed as fast as possible. Which of the following statements about the automation solution is BEST in this scenario?

• A. The TAS should support mainly client-side automation for SUT1 and server-side automation for SUT2
• B. The TAS should support mainly server-side automation for both SUT1 and SUT2
• C. The TAS should support mainly server-side automation for SUT1 and client-side automation for SUT2
• D. The TAS should support mainly client-side automation for both SUT1 and SUT2

As a TAE, you are evaluating a test automation tool to automate some UI tests for a web app. The automated tests will first locate the required HTML elements on the web page using their corresponding identifiers (locators), then perform actions on those elements, and finally check the presence of any expected text for an HTML element. These tests are independent of each other and are organized into a test suite that must be run every night against the most recent build of the web app. There is a high risk that the web app will crash while running some automated tests. Based only on the given information, which of the following is your MOST important concern related to the evaluation of the test automation tool?

• A. Does the test automation tool provide a feature to specify automated tests in a descriptive meta- language that is not directly executable on the web app?
• B. Does the test automation tool support a licensing scheme that allows accessing different feature sets?
• C. Does the test automation tool offer a feature to create a mock server that simulates the behavior of a real API by accepting requests and returning responses?
• D. Does the test automation tool offer a feature to restore the web app, recover from the failed test, skip such tests, and resume the next one in the suite?

As a TA-E, you have successfully verified that a test automation environment and all other components of the TAS are working as expected. Now your goal is to verify the correct behavior for a given automated test suite that will be run by the TAS. Which of the following should NOT be part of the verifications aimed at achieving your goal?

• A. Are all automated tests within the suite complete in terms of test data, including expected results?
• B. Is the connectivity between the TAS and the necessary internal and external systems available and stable?
• C. Do all automated tests within the suite always provide the same results across multiple runs?
• D. Does the level of intrusion of automated test tools influence confidence in the suite's test results?
