Automated tests at the UI level for a web app adopt an asynchronous waiting mechanism that allows them to synchronize test steps with the app, so that they are executed correctly and at the right time, only when the app is ready and has processed the previous step: this is done when there are no timeouts or pending asynchronous requests. In this way, the tests automatically synchronize with the app's web pages. The same initialization tasks to set test preconditions are implemented as test steps for all tests. Regarding the pre- processing (Setup) features defined at the test suite level, the TAS provides both a Suite Setup (which runs exactly once when the suite starts) and a Test Setup (which runs at the start of each test case in the suite).
Which of the following recommendations would you provide for improving the TAS (assuming it is possible to perform all of them)?

• A. Adopt a manual synchronization with the app's web pages using hard-coded waits instead of the current automatic synchronization
• B. Implement the initialization tasks aimed at setting the preconditions of the tests within the Test Setup feature at the test suite level
• C. Adopt a manual synchronization with the app's web pages using dynamic waits via polling instead of the current automatic synchronization
• D. Implement the initialization tasks aimed at setting the preconditions of the tests within the Suite Setup feature at the test suite level

Consider a TAS aimed at implementing and running automated test scripts at the UI level on web apps. The TAS must support cross-browser compatibility for a variety of supported browsers, by ensuring that the same test script will run on such browsers in the same way without making any changes to it. This is achieved by introducing appropriate abstractions into the TAA for connection and interaction with different browsers.
Because of this, the TAS will be able to make direct calls to the supported browsers using each different browser's native support for automation. Which of the following SOLID principles was adopted?

• A. Open-closed principle
• B. Liskov substitution principle
• C. Dependency inversion principle
• D. Interface segregation principle

(Which of the following statements about how test automation is applied across different software development lifecycle models is TRUE?)

• A. In Agile software development, automated regression test suites sometimes grow so large that they can become difficult to maintain, and thus, it becomes crucial to invest in test automation at multiple test levels
• B. Unlike Agile software development, where automated unit tests are written by developers, often in a test-first fashion, in a V-model, automated unit tests are written by testers as part of unit testing
• C. In a Waterfall model, automated tests are usually executed only during the last phase of the development lifecycle, but their implementation occurs in the early stages
• D. In Agile software development, regardless of context (e.g., type of application to be developed, tools available), test automation must be based on the test automation distribution known as the test pyramid model

Which of the following statements about the relationship between TAA, TAS and TAF is true?

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

A TAS that performs automated testing in a single test environment was successfully manually installed and configured from a central repository, with all its components in the correct versions. It was also verified that all TAS components in this environment are capable of providing reliable and repeatable performance. The TAS will be used to run several suites of automated regression test scripts on various SUTs in the test environment. Your current goal is to complete all preliminary verifications to ensure that the TAS works correctly. Which of the following activities would you perform FIRST?

• A. Create scripts to automatically install and configure the TAS in the test environment from the central repository
• B. Run a given suite multiple times using TAS to determine whether all regression test scripts always provide the same result
• C. Check whether all regression test scripts in a given suite have expected results
• D. Check whether the TAS connectivity to all required internal systems, external systems, and interfaces is available
