• A.A TAS can be used to implement a TAF, which is an implementation of a TAA
• B.A TAS can be used to implement a TAA, which is an implementation of a TAF
• C.A TAF can be used to implement a TAA, which is an implementation of a TAS
• D.A TAF can be used to implement a TAS, which is an implementation of a TAA

The last few runs for a suite of automated keyword-driven tests on a SUT were never completed. The test where the run was aborted was not the same between runs. Currently, it is not possible to identify the root cause of these aborts, but only determine that test execution aborted when exceptions (e.g., NullPointerException, OutOfMemoryError) occurred on the SUT by analyzing its log files. Test execution log files are currently generated, in HTML format, by the TAS as follows: all expected logging data is logged for each keyword in intermediate log files. This data is then inserted into the final log file only for keywords that fail, while only a configurable subset of that data is logged for keywords that execute successfully. Which of the following actions (assuming it is possible to perform all of them) would you take FIRST to help find the root cause of the aborts?

• A.Log all expected logging data in the final test execution log file, not only for keywords that fail, but also for keywords that execute successfully
• B.Use appropriate colors to effectively visually highlight different types of information in the test execution log files
• C.Log the stack trace and amount of memory available to the SUT at the start and end of each test in the suite, in the SUT log files
• D.Split the generated log file into smaller parts, load them into external files that are loaded into the browser in transparent mode when needed

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.Implement a mechanism to automatically reboot the entire web app in the event of a crash
• B.Split the suite into sub-suites and run each of them concurrently on different test environments
• 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

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.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
• B.Log all the messages directly on the corresponding log files associated with the specific execution to ensure the permanent storage of test execution logs
• C.Avoid logging the messages that occur during the specified bursts to minimize any potential performance overhead in test execution
• D.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

(Which of the following aspects of "design for testability" is MOST directly associated with the need to define precisely which interfaces are available in the SUT for test automation at different test levels?)

• A.Controllability
• B.Architecture transparency
• C.Autonomy
• D.Observability
