Questions # 21:

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?

Options:

The code coverage achieved with the automated tests, for each new release of the SUT

The number of automated tests which fail because of a single software defect, for each new release of the SUT

The time it takes to execute all the automated tests, for each new release of the SUT.

The number of automated tests requiring maintenance, for each new release of the SUT.

Answer

Explanation

The most crucial metric to collect in order to determine the maintenance effort for automated tests in a regression test suite, especially for a system under test (SUT) that undergoes frequent releases, is the number of automated tests requiring maintenance. This metric directly reflects the impact of changes in the SUT on the test suite. High maintenance needs can indicate that the automated tests are tightly coupled to the SUT, which may require a redesign of the test automation strategy to improve maintainability and reduce future effort.

References = The ISTQB Test Automation Engineer syllabus emphasizes the importance of metrics in monitoring the effectiveness of test automation. It specifically mentions the need to manage and optimize testing assets to facilitate maintainability, which aligns with the concept of measuring the number of tests requiring maintenance12.

Questions # 22:

You are executing the first test run of a test automation suite of 200 tests. All the relevant information related to the state of the SUT and to the automated test execution is stored in a small database. During the Automated test run you observe that the first 10 test pass, while an abnormal termination occurs when executing the 11th test. This test does not complete its execution and the overall execution of the suite is aborted. An immediate analysis of the abnormal termination is expected to be time consuming and you have been asked to produce a detailed report of the execution results for the first test run, as soon as possible.

What is the MOST important FIRST step to be taken immediately after the abnormal occurred when executing the 11th test?

Options:

Re-run the test automation suite starting from the 12th test

Return the database to a consistent state that allows subsequent test to run

Take a backup of the database in its current state. So It can be analyzed later

Re-run the test automation suite starting from the 1st test.

Answer

Explanation

The most crucial first step after an abnormal termination is to take a backup of the database in its current state. This ensures that you have a snapshot of the system at the point of failure, which is invaluable for a thorough post-mortem analysis. Without this, you may lose critical information about the state of the system that could help identify the root cause of the failure. Once the backup is secured, you can proceed with restoring the system to a consistent state and continue with subsequent tests or rerun the test suite as needed.

References = The ISTQB Test Automation Engineer syllabus and best practices highlight the importance of error recovery processes and the preservation of test artifacts for analysis. Taking a backup aligns with these guidelines as it allows for an accurate assessment of the failure and aids in improving the

Questions # 23:

You are reviewing the testability of your SUT.

Which of the following BEST refers to the characteristic of OBSERVABILITY?

Options:

The ability of the SUT to perform its intended function for a specified period of time

The ability to exercise the SUT by entering inputs, triggering events and invoking methods

The ability of the SUT to prevent unauthorized access to its components or data.

The ability to identify states, outputs, intermediate result and error messages in the SUT

Answer

Explanation

Observability in the context of a System Under Test (SUT) refers to the degree to which the internal states of the system can be inferred from knowledge of its external outputs. It is a measure of how well internal states of a system can be understood by examining its outputs. In test automation, observability is crucial because it allows testers to understand what is happening inside the SUT without having direct access to its internal workings. This characteristic is essential for identifying and diagnosing issues, understanding system behavior, and ensuring that the system is functioning correctly. High observability means that the system’s outputs, including its states and any intermediate results or error messages, are readily available for examination, which is vital for effective testing and debugging.

References = The ISTQB Test Automation Engineer syllabus and study materials emphasize the importance of observability as part of the testability of systems. It is highlighted as a key characteristic that enables testers to detect defects and understand system behavior through the outputs the system provides during test execution123.

Questions # 24:

Your company is new to test automation and as TAE. you have designed a TAS which successfully supports the SUT for the current project.

There are other systems currently in operation which have been tested manually and more systems are planned over the coming years. Based on this success, your company requires test automation be rolled out to other current and future SUTs with consistency being a key objective.

Which of the following is the BEST way to achieve that?

Options:

Design a new TAS for each SUT, and manage each one through a dedicated automation support team.

Install the current TAS into a central repository so that other tests on different SUTs use the same version of the TAS.

Check for correct connectivity to internal and external systems to ensure that the TAS has been installed and configured correctly for each SUT.

Develop a tool that keeps track of automation failures across the different SUTs and produces regular reports to stakeholders.

Answer

Explanation

Installing the current Test Automation System (TAS) into a central repository allows for consistent use across different Systems Under Test (SUTs). This approach promotes reusability and maintainability of the automation scripts and resources, which is crucial for a company that is expanding its test automation efforts. By using the same version of the TAS, the company ensures that all teams are working with the same tools and standards, which facilitates collaboration and reduces the complexity associated with managing multiple versions of the TAS. Additionally, it helps in streamlining the automation process, as updates and improvements to the TAS can be disseminated quickly and efficiently to all SUTs.

References = The answer is based on the principles outlined in the ISTQB Test Automation Engineer certification materials, which emphasize the importance of consistency, maintainability, and efficiency in test automation practices123.
