ISQI ISTQB Certified Tester Advanced Level - Test Automation Engineering CTAL-TAE (Syllabus v2.0) 認定 CTAL-TAE_V2 試験問題:
1. Consider a TAS implemented to perform automated testing on native mobile apps at the UI level, where the TAF implements a client-server architecture. The client runs on-premise and allows creation of automated test scripts using TAF libraries to recognize and interact with the app's UI objects. The server runs in the cloud as part of a PaaS service, receiving commands from the client, translating them into actions for the mobile device, and sending the results to the client. The cloud platform hosts several mobile devices dedicated for use by this TAS. The device on which to run test scripts/test suites is specified at run time. You are currently verifying whether the test automation environment and all other TAS/TAF components work correctly. Which of the following activities would you perform to achieve your goal?
A) Check whether the TAF libraries that the test scripts will use to recognize and interact with the app's UI objects (widgets) function as expected
B) Manage the infrastructure that hosts the server, including hardware, software updates, and security patches
C) Check whether all test scripts that will be executed by the TAS as part of a given test suite have expected results
D) Check whether the references to the device on which the given test scripts/test suites will be executed are correctly hard-coded within these test scripts/test suites
2. (Which of the following statements refers to a typical advantage of test automation?)
A) Automated tests can allow defects to be detected earlier than manual tests because their execution times can be shorter
B) Automated tests can determine whether actual results match expected results, even for non-machine- interpretable results
C) On average, automated tests written at the API level are likely to run faster than automated tests written at the UI level
D) Artificial intelligence can be used to help identify redundant tests within large, long-running automated regression test suites
3. Automated tests run by a TAS on a SUT can be subject to sudden bursts of messages to log during their execution. All log messages that occur during execution must be permanently stored in the corresponding test execution logs by the TAS for later analysis. If logging is not performed correctly, these bursts can reduce the execution speed of these automated tests, causing them to produce unreliable results. Which of the following solutions would you expect to be MOST useful to address this issue for TAS logging?
A) Log all the messages in memory using a circular buffer and periodically flush the buffer to the corresponding log files associated with the specific execution
B) Use a Network Time Protocol (NTP) server to ensure that the clocks of the machines running TAS and SUT are synchronized with a common time source
C) Avoid logging the messages that occur during the specified bursts to minimize any potential performance overhead in test execution
D) Log all the messages directly on the corresponding log files associated with the specific execution to ensure the permanent storage of test execution logs
4. A suite of automated test cases was run multiple times on the same release of the SUT in the same test environment. Consider analyzing a test histogram that shows the distribution of test results (pass, fail, etc.) for each test case across these runs. Which of the following potential issues is MOST likely to be identified as a result of such an analysis?
A) Unstable automated test cases
B) Maintainability issues in automated test cases
C) Security vulnerabilities in automated test cases
D) Outliers in test execution times
5. 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) Test-Driven Development (TDD)
B) Linear scripting
C) Capture/playback
D) Structured scripting
