Questions 5

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?

Options:

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 in memory using a circular buffer and periodically flush the buffer to the corresponding log files associated with the specific execution

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 directly on the corresponding log files associated with the specific execution to ensure the permanent storage of test execution logs

Questions 8

You are working on a TAS for standalone application. The automated tests are developed based on a automation framework that allows interaction with GUI elements using on object orientated API. The GUI elements include menus, buttons, radio buttons, text toolbars and their properties.

Options:

A.

Verify the testability support with the providers of the third party components

B.

All the automated tests will use these test interfaces when interacting with the SUT. Assume that you are currently verifying the correctness of the automated test environment and test tool setup.

Which of the following would you expect to be the MOST specific risk associated with this scenario?

Options:

A.

The connectivity from the TAS to the dedicated test interfaces will not work

B.

Questions 10

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 façade 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)?

Options:

A.

Modify the TAF so that test scripts are based on the page object model, rather than the flow model pattern

B.

Implement a mechanism to automatically reboot the entire web app in the event of a crash

C.

Split the suite into sub-suites and run each of them concurrently on different test environments

D.

Modify the architecture of the SUT to improve its testability and, if necessary, the TAA accordingly

Questions 21

Consider a TAS deployed into production. The SUT is a web application and the test suite consists of a set of automated regression tests developed via GUI. A keyword-driven framework has been adopted for automating the regression tests. The tests are based on identification at low-levels of the web page components (e.g class indexes, tab sequence indexes and coordinates) in the next planned release the SUT will be subject to significant corrective maintenance (bug-fixes) and evolution (new features) Maintenance costs to update the test scripts should be as low as possible and the scripts must be highly reusable.

Which of the following statements is most likely to be TRUE?

The keyword-driven framework is not suitable, it would be better to adopt a structured-scripting approach

B.

False positive errors are likely to occur when running the automated tests on the new releases without modifying the test

C.

The total execution time of the automated regression test suite will decrease for each planned release.

D.
