ISQI ISTQB Certified Tester Advanced Level - Test Automation Engineering CTAL-TAE (Syllabus v2.0) 認定 CTAL-TAE_V2 試験問題:

1. (In User Acceptance Testing (UAT) for a new SUT, in addition to the manual tests performed by the end- users, automated tests are performed that focus on the execution of repetitive and routine test scenarios. In which of the following environments are all these tests typically performed?)

A) Production environment
B) Integration environment
C) Build environment
D) Preproduction environment

2. 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

3. 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

4. Which of the following practices can be used to specify the active (i.e., actually available) features for each release of the SUT and determine the corresponding automated tests that must be executed for a given release?

A) Feature-driven development
B) The use of feature files
C) The use of feature toggles
D) Test-driven development

5. 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) Interface segregation principle
B) Open-closed principle
C) Dependency inversion principle
D) Liskov substitution principle
