(Which of the following statements refers to a typical advantage of test automation?)

• A. On average, automated tests written at the API level are likely to run faster than automated tests written at the UI level
• B. Automated tests can determine whether actual results match expected results, even for non-machine- interpretable results
• C. Automated tests can allow defects to be detected earlier than manual tests because their execution times can be shorter
• D. Artificial intelligence can be used to help identify redundant tests within large, long-running automated regression test suites

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. 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
• B. First upgrade the OS, then implement the change in the API authentication method, and finally run all the updated test scripts
• C. Implement one change at a time and run a subset of the updated test scripts after each change
• D. First implement the change in the API authentication method, then upgrade the OS, and finally run all the updated test scripts

Which of the following BEST describes why it is important to separate test definition from test execution in a TAA?

• A. It allows specify test cases without being closely tied to the tool to run them against the SUT
• B. It allow choosing different paradigms (e.g event-driven) for the interaction TAS and SUT
• C. It allows testers to find more defects on the SUT
• D. It allows developing steps of the test process without being closely tied to the SUT interface.

A release candidate of a SUT, after being fully integrated with all other necessary systems, has successfully passed all required functional tests (90% were automated tests and 10% were manual tests). Now, it is necessary to perform reliability tests aimed at evaluating whether, under certain conditions, that release will be able to guarantee an MTBF (Mean Time Between Failures) in the production environment higher than a certain threshold (expressed in CPU time). Which of the following test environments is BEST suited to perform these reliability tests?

• A. Build environment
• B. Preproduction environment
• C. Local development environment
• D. Integration environment

Which of the following is NOT a technical design consideration for a TAA?

• A. Standards and Legal requirements, e.g data privacy
• B. Availability of interfaces for the SUT to be testable
• C. Data used by the SUT, e.g configuration, users
• D. The number of users for the SUT
