ISQI CTAL-TAE Exam : ISTQB Certified Tester Advanced Level, Test Automation Engineering

Consider a TAS that is going to be deployed for the first time. The TAS requires share resources and run it its own test environment. The infrastructure for the TAS has been created along with maintenance procedures. It is very unlikely the TAS will be required to work in other target Environments. There is a high-risk that when the TAS is deployed in its own test environment, a number of existing application will no longer work because of conflicts with the existing shared resources.
Which of the following activities would you expect to be MOST effective at mitigating the risk associated with the first deployment of the TAS?

• A. Testing the TAS for its ability to be implemented in other target test environments.
• B. Testing the TAS for regressions due to optimization that fix non-functional issues.
• C. Testing the TAS for ITS ability to run a shared test environment
• D. Testing the TAS for application compatibility issues in the target environment

Which of the following statements about contract testing is TRUE?

• A. The differences between the two approaches to contract testing stem primarily from which side creates the contract: this creation is done by the provider for the provider-driven approach and by the consumer (s) for the consumer-driven approach
• B. Contract testing, regardless of the approach chosen (provider-driven or consumer-driven) does not need to rely on the creation of stubs/mocks since it is used to implement integration testing, not unit
  /component testing
• C. Contract testing can be viewed as a specialized form of API testing that can be applied to effectively and efficiently test integration between microservices, but only if they interact with REST APIs
• D. Contract testing can be viewed as a specialized form of API testing that can be applied to effectively and efficiently test integration between systems, but only if they interact synchronously

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 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
• B. Check whether all test scripts that will be executed by the TAS as part of a given test suite have expected results
• C. 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
• D. Manage the infrastructure that hosts the server, including hardware, software updates, and security patches

An automated test case that should always pass sometimes passes and sometimes fails intermittently (non- deterministic behavior) when executed in the same test environment, even if no code (i.e., SUT code or the test automation code) has been changed. Which of the following statements about the root cause of this non- deterministic behavior is TRUE?

• A. The specified root cause is a race condition that can be identified by also analyzing the log files of the test case, the SUT, and the TAF
• B. The specified root cause must be in the instability of the test environment, since no code has been changed
• C. Determining the specified root cause is certainly easier than if the automated test always fails (deterministic behavior)
• D. Determining the specified root cause may require, in addition to the TAE, the support of others such as developers and system engineers

Which of the following statements about the reuse of TAS artefacts is TRUE?

• A. Reusable TAS artifacts associated with the definition layer of the TAA include the adaptors to the SUT components and/or interfaces
• B. To enable reuse of TAS artefacts, a good design for reuse is built into the TAA and to further action are needed during the TAS lifecycle
• C. Reusable TAS artefacts can include components (or parts of components) associated with different layers of the TAA
• D. Communications maintenance and improvements for reusing TAS artefacts are modify addressed during the design of the TAA
