1. An API's response to a request made to the corresponding endpoint should return some specific data about a payment transaction in JSON format. In particular, your goal is to write the test automation code, keeping it as short as possible, aimed at determining whether that response includes certain properties (transaction_id, amount, status, timestamp) with the data types and formats expected. Assuming that the TAF provides all the necessary support to validate the specified API response, how would you BEST achieve your goal?

A) Specify the schema for the expected response data (properties, data types, and formats) and validate the actual response data against this schema
B) Write custom code that parses the actual response data and checks whether the extracted properties, data types, and formats are as expected
C) Use an artificial intelligence algorithm based on machine learning and image recognition to implement a self-healing capability
D) Write a single assertion for each property to check whether the data types and formats for that property are as expected in the actual response

2. 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 SUT1 and client-side automation for SUT2
B) The TAS should support mainly client-side automation for both SUT1 and SUT2
C) The TAS should support mainly server-side automation for both SUT1 and SUT2
D) The TAS should support mainly client-side automation for SUT1 and server-side automation for SUT2

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

4. Consider choosing an approach for the automated implementation of manual regression test suites written at the UI level for some already developed web apps. The TAS is based on a programming language that allows the creation of test libraries and provides a capture/playback feature that allows recognition and interaction with all widgets in the web UIs being tested. The automated tests will be implemented by team members with strong programming skills. The chosen approach should aim to reduce both the effort required to maintain automated tests and the effort required to add new automated tests. Which of the following approaches would you choose?

A) Linear scripting
B) Test-Driven Development (TDD)
C) Capture/playback
D) Structured scripting

5. 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) Modify the TAF so that test scripts are based on the page object model, rather than the flow model pattern
B) Split the suite into sub-suites and run each of them concurrently on different test environments
C) Implement a mechanism to automatically reboot the entire web app in the event of a crash
D) Modify the architecture of the SUT to improve its testability and, if necessary, the TAA accordingly
