CT-TAE Exam Dumps : Certified Tester Test Automation Engineer

 The most significant risk for the Test Automation System (TAS) in this scenario is related to the level of abstraction and the departure of the automation architect. The architect’s role is crucial in designing and maintaining the architecture of the TAS. Their departure can lead to challenges in understanding the system’s design and making necessary updates or changes. The level of abstraction means that the system is designed in a way that may not be easily understood without the architect’s insight, which can make maintenance difficult. This risk is compounded when the TAS is used across several projects, each with its own library of keywords, which requires a deep understanding of the system’s architecture to manage effectively.

References = This answer is based on the principles outlined in the ISTQB Test Automation Engineer syllabus, which discusses the importance of maintainability and the risks associated with high levels of abstraction in test automation architectures12. The syllabus also emphasizes the role of the automation architect in ensuring the long-term success of the TAS2.

 In a scenario where manual testers are overwhelmed by regression testing, leading to insufficient coverage of new features and an increase in defects, the most pertinent metric to track the value of test automation is the Equivalent Manual Test Effort (EMTE) for the automated tests (Option B). This metric compares the effort required to execute tests manually with the effort saved through automation. By quantifying the time and resources saved by automating regression tests, the TAE can demonstrate the TAS's impact on freeing up manual testers to focus on new feature testing, thereby improving the overall quality and efficiency of the testing process. Tracking EMTE highlights the direct benefits of automation in optimizing testing resources and supports the business case for continued or expanded investment in test automation, especially in scenarios where meeting deadlines and maintaining product quality are critical challenges.

For the scenario of automating functional tests at the system test level via the Command Line Interface (CLI) of the SUT, with the requirements for fast and cheap maintenance, low cost for adding new tests, and high independence from the automation tool, the most suitable scripting technique is Data-driven scripting. This approach externalizes test data from the scripts into separate data files or repositories, allowing for the reuse of test scripts with different sets of data. Data-driven scripting is ideal for meeting the specified requirements because it enables rapid execution of a large number of test cases by merely changing the input data, without the need to alter the scripts themselves. This significantly reduces maintenance costs and the effort required to add new tests, as the core script remains the same. Moreover, this technique enhances the independence of the automated tests from the specific tools used, as the focus is on the data and the generic actions performed by the scripts, making it the most suitable choice for the described needs.
