Question 1

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 adaptation layer

D. Test execution layer

Question 2

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 a lower level of intrusion than the alternative implementation, and therefore its test scripts are less likely to produce false positives

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 more likely to produce false positives

D. 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

Question 3

Some automated regression test scripts run by a TAS in a given test environment make calls to private APIs that require authentication for all requests (the authentication method is the same for all APIs). The SUT is a business-critical system. The following two changes are planned: a change in the authentication method of all APIs and a minor upgrade of the OS (Operating System) in the test environment. You have updated the test scripts to cope with the change in the API authentication method. Which of the following sequences of activities is BEST to ensure that the test scripts are not adversely affected by these changes?

A. First implement the change in the API authentication method, then upgrade the OS, and finally run all the updated test scripts

B. Implement one change at a time and run a subset of the updated test scripts after each change

C. First upgrade the OS, then implement the change in the API authentication method, and finally run all the updated test scripts

D. Implement one change at a time and run a subset of the updated test scripts after each change, and finally run all the updated test scripts

Question 4

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 server-side automation for both SUT1 and SUT2

B. The TAS should support mainly client-side automation for SUT1 and server-side automation for SUT2

C. The TAS should support mainly client-side automation for both SUT1 and SUT2

D. The TAS should support mainly server-side automation for SUT1 and client-side automation for SUT2

Question 5

An automated test case that should always pass sometimes passes and sometimes fails intermittently (non- deterministic behavior) when executed in the same test environment, even if no code (i.e., SUT code or the test automation code) has been changed. Which of the following statements about the root cause of this non- deterministic behavior is TRUE?

A. Determining the specified root cause is certainly easier than if the automated test always fails (deterministic behavior)

B. The specified root cause is a race condition that can be identified by also analyzing the log files of the test case, the SUT, and the TAF

C. Determining the specified root cause may require, in addition to the TAE, the support of others such as developers and system engineers

D. The specified root cause must be in the instability of the test environment, since no code has been changed
