ISQI ISTQB Certified Tester Advanced Level - Test Automation Engineering CTAL-TAE (Syllabus v2.0) Sample Questions:

1. 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) 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
B) Log all the messages directly on the corresponding log files associated with the specific execution to ensure the permanent storage of test execution logs
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 in memory using a circular buffer and periodically flush the buffer to the corresponding log files associated with the specific execution

2. Which of the following statements about the relationship between TAA, TAS and TAF is true?

A) A TAF can be used to implement a TAS, which is an implementation of a TAA
B) A TAS can be used to implement a TAF, which is an implementation of a TAA
C) A TAF can be used to implement a TAA, which is an implementation of a TAS
D) A TAS can be used to implement a TAA, which is an implementation of a TAF

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

4. An automated test script makes a well-formed request to a REST API in the backend of a web app to add a single item for a product (with ID = 710) to the cart and expects a response confirming that the product is successfully added. The status line of the API response is HTTP/1.1 200 OK, while the response body indicates that the product is out of stock. The API response is correct, the test script fails but completes, and the message to log is: The product with ID = 710 is out of stock. Cart not updated. When this occurs, you are already aware that both the failed test and the API are behaving correctly and that the problem is in the test data. The TAS supports the following test logging levels: FATAL, ERROR, WARN, INFO, DEBUG. Which of the following is the MOST appropriate test logging level to use to log the specified message?

A) INFO
B) WARN
C) DEBUG
D) FATAL

5. (Which of the following aspects of "design for testability" is MOST directly associated with the need to define precisely which interfaces are available in the SUT for test automation at different test levels?)

A) Autonomy
B) Controllability
C) Architecture transparency
D) Observability
