As a TA-E, you have successfully verified that a test automation environment and all other components of the TAS are working as expected. Now your goal is to verify the correct behavior for a given automated test suite that will be run by the TAS. Which of the following should NOT be part of the verifications aimed at achieving your goal?

• A.Do all automated tests within the suite always provide the same results across multiple runs?
• B.Does the level of intrusion of automated test tools influence confidence in the suite's test results?
• C.Are all automated tests within the suite complete in terms of test data, including expected results?
• D.Is the connectivity between the TAS and the necessary internal and external systems available and stable?

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

Which of the following recommendations can help improve the maintainability of test automation code?

• A.Avoid using static analyzers on test automation code and other development tools, as they are designed to improve the maintainability of SUT code
• B.Avoid adopting design patterns that introduce high levels of abstraction in test automation code, such as the flow model pattern
• C.Use error codes in test automation code instead of exceptions (if exceptions are supported by the programming language) for error handling
• D.Avoid producing test automation code containing methods with too many levels of nesting, as deeply nested code is more difficult to understand

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 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
• C.Has a higher level of intrusion than the alternative implementation, and therefore its test scripts are less likely to produce false positives
• D.Has a lower level of intrusion than the alternative implementation, and therefore its test scripts are more likely to produce false positives

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