Test automation does not inherently find more defects than manual testing; it executes pre-scripted tests against the software. The effectiveness of finding defects is determined by the quality of the test cases, whether automated or manual. Automated tests run the same steps consistently every time they are executed, which means they are not designed to find new defects unless the test scripts are updated to reflect changes in the test cases or the system under test.

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.

Introducing a ‘TAS error’ status (b) would provide a clear distinction between failures caused by the SUT and those due to issues within the TAS itself, which is essential for accurate failure analysis and effective defect reporting. Including system configuration information (e), such as software/firmware and operating system versions, is also critical. This information can significantly aid developers in reproducing issues, as it provides context about the environment in which the test was executed.

In an Agile project, it is crucial to maintain the integrity of the regression suite to ensure that it reliably verifies the application’s functionality as new changes are introduced. When inconsistencies in test results are observed, as in the case of the two test cases that passed in sprints 1 and 4 but failed in sprints 2 and 3, it is important to address these issues promptly to prevent potential defects from being overlooked.

Quarantining the inconsistent test cases allows the regression suite to continue to be executed without the risk of these tests affecting the overall results. This approach also enables the Test Automation Engineer (TAE) to conduct a root cause analysis in parallel to determine why the test cases are producing inconsistent results. By doing so, the TAE can identify whether the issue lies within the test cases themselves, the test environment, or the application under test.

This course of action aligns with best practices for maintaining test reliability and effectiveness in an Agile environment, where rapid iterations and continuous integration are key. It ensures that the rest of the regression suite can still provide valuable feedback on the application’s quality, while the problematic tests are being investigated and resolved.

Separating test definition from test execution in a Test Automation Architecture (TAA) is crucial for ensuring flexibility and maintainability in test automation efforts. The best reason for this separation is option B: It allows the test definition to be completed without knowledge of the tool that will be used for execution. This separation abstracts the process of defining what to test (test definition) from how to test (test execution). By decoupling these aspects, test definitions can be written in a more tool-agnostic manner, focusing solely on the testing objectives, requirements, and criteria without being constrained by the capabilities or limitations of any specific test execution tools. This approach not only enhances the reusability of test cases across different tools and environments but also facilitates easier maintenance and updates to the test suite as testing tools evolve or change. It enables a more sustainable and adaptable test automation framework that can better respond to changes in technology, tools, and testing needs over time.
