ISTQB CT-TAE 問題集

質問 1：
You have been asked to implement test automation for a project that is not meeting its deadlines. After further analysis you discover that the manual testers are not able to keep up with the new feature testing because the regression testing is taking 75% of their time. As a result, the new features are being released with many defects and customers are complaining about the quality.
Given this information, what metric SHOULD you be tracking to show the value of test automation for this project?
A. Percentage of builds accepted/rejected by the automated tests.
B. Percentage of code covered by the test automation.
C. Number of defects found by test automation.
D. Equivalent Manual Test Effort for the automated tests.

質問 2：
Assume that you are the TAE responsible for the correct functioning of a TAS, deployed in a test environment that consists of a few machines running the same version of the operating system. The TAS has been working and stable since its deployment, it has been used to run an automated test suite consisting of many similar automated test. The infrastructure team is planning to update the operating system on these machines by installing a new the service pack for security reasons. Since the vendor of the operating system assurance full backward compatibility, the infrastructure team assurance that there will be no impacts on the functioning of the TAS.
What is the BEST approach to confirm the correct functioning of the TAS in this scenario?
A. Do not run any tests because you can immediately confirm the correct functioning of the automated test suite
B. Make sure that the infrastructure team has completed installing the service pack on the machines where SUT is running, then run the whole automated test suite to verify its behavior
C. Verify the behavior of the whole automated test suite by running all the automated tests
D. Verify the behavior of the automated tests by running a small tests, then gradually run the remaining tests to confirm the correct functioning of the whole automated test suite.

質問 3：
What are the four horizontal layers of the gTAA?
A. Test adaptation, test execution, test design, test definition
B. Test generation, test execution, test definition, test APIs
C. Test generation, test definition, test execution, test adaptation
D. Test definition, test execution, test reporting, test adaptation

質問 4：
New features have been added for the current release of a SUT.
Which action would NOT be appropriate for the TAE to perform when evaluating the impact on the TAS?
A. Review existing keywords to see if they need to be modified.
B. Run existing automated tests against the updated SUT to verify and record any changes to their correct operation.
C. Evaluate compatibility with existing test tools and, where necessary, identify alternative solutions.
D. Gather feedback from the Business Analysts to determine if the current TAS will meet the needs of the new features.

質問 5：
You are reviewing the testability of your SUT.
Which of the following BEST refers to the characteristic of OBSERVABILITY?
A. The ability of the SUT to prevent unauthorized access to its components or data.
B. The ability to exercise the SUT by entering inputs, triggering events and invoking methods
C. The ability of the SUT to perform its intended function for a specified period of time
D. The ability to identify states, outputs, intermediate result and error messages in the SUT
正解：D

質問 6：
You have inherited a TAS that is working well it uses keyword-driven scripting and was well architected. The automation architect who built the system has now moved on to another company. The TAS is working across several projects and has a multiple library of keywords, categorised by project. The individual project teams maintain these keyword scripts.
Based only on the given information, what is the MOST significant risk for the TAS?
A. The keyword driven scripts may become out of date if not maintained
B. The level of abstraction, coupled with the departure of the architect may make the system hard to maintain
C. Because the keyword scripts are maintained by different teams, there is a likelihood that good coding standards are not followed
D. New projects may not work as well with the TAS as the current projects
正解：B

質問 7：
Consider a TAS associated to dynamically changing software frequent releases. Your goal is to determine the amount of effort required to maintain the automated tests of the regression test suite for each new release of the SUT.
What is the MOST important metric to collect to achieve your goal?
A. The number of automated tests requiring maintenance, for each new release of the SUT.
B. The code coverage achieved with the automated tests, for each new release of the SUT
C. The number of automated tests which fail because of a single software defect, for each new release of the SUT
D. The time it takes to execute all the automated tests, for each new release of the SUT.
正解：A

質問 8：
You are currently designing the TAA of a TAS. You have been asked to adopt an approach for automatically generating and executing test cases from a model that defines the SUT. The SUT is a state-based and event-driven that is described by a finite-state machine and exposes its functionality via an API. The behavior of the SUT depends on hardware and communication links that can be unreliable.
Which of the following aspects is MOST important when designing the TAA in this scenario?
A. Adopting a test definition strategy based on use case/exception case coverage for the definition layer.
B. Looking for tools that allow performing setup and teardown of the test suites and the SUT.
C. Looking for tools that allows direct denoting of exceptions and actions depending on the SUT events.
D. Adopting a test definition strategy based on classification tree coverage for the test definition layer.
正解：A
