CT-TAE Certified Tester Test Automation Engineer Question and Answers

A test execution report is primarily used to identify problematic areas of the System Under Test (SUT) by maintaining a history of which test cases fail most frequently. This allows teams to track trends over time, pinpoint recurring issues, and focus their testing and development efforts on the most problematic areas. The report serves as a historical record that can be analyzed to improve the quality and reliability of the SUT.

References = The use of test execution reports in test automation is well-documented in industry best practices and resources. These reports are essential for providing a consolidated summary of the testing performed, highlighting areas for improvement, and enabling informed decision-making for optimizing testing strategies12. They are not typically used to understand individual test step failures, measure test coverage, or record how failures have been fixed, as those are often addressed in more specific testing documentation or tools.

The re-occurrence of a defect that has been previously resolved and validated can be attributed to issues in the configuration management process. If the configuration management process is not robust, it may fail to maintain proper synchronization between software archives. This can lead to situations where the defect re-emerges in future releases because the software components are not correctly integrated or updated with the defect fix. Effective configuration management is crucial for ensuring that all software artifacts are correctly versioned and that changes are properly tracked and integrated across all versions of the software. References = The ISTQB Test Automation Engineer syllabus outlines the importance of configuration management in relation to test automation and defect management. It emphasizes the need for proper control and synchronization of software archives to prevent the re-occurrence of defects123.

When evaluating test modeling tools, the inability to export generated test cases into a preferred format like .csv can be a significant limitation. The best next step in this scenario, given that the tool meets all other requirements except for the export facility, is to inquire with the vendor and explore community forums to determine if a solution is available or planned for future releases (Option C). Engaging with the vendor and the user community can provide insights into workarounds, upcoming features, or third-party plugins that might address the export functionality gap. This approach allows leveraging the tool's strengths while exploring possibilities to overcome its limitations without immediately discarding it for lacking a single feature. It also opens opportunities for customization or collaboration with the vendor to enhance the tool's capabilities according to user needs.

For a Test Automation Solution (TAS) that utilizes a third-party capture-replay tool, it is crucial to ensure that: a) The tool is placed under configuration management control. This is important to maintain consistency across different environments and versions, and to manage changes effectively. c) Information about updates and new versions of the tool is obtained and applied. Keeping the tool up-to-date ensures that the latest features and fixes are utilized, which can improve the efficiency and effectiveness of the TAS.

Placing the tool under configuration management control and staying informed about updates are essential practices for maintaining the reliability and integrity of the TAS.

References = The answer is based on the best practices for test automation as outlined in the ISTQB Test Automation Engineer syllabus, which includes the management of test tools and the importance of keeping software up-to-date as part of configuration management123.

 When evaluating the impact of new features on the Test Automation Solution (TAS), it would not be appropriate for the Test Automation Engineer (TAE) to gather feedback from Business Analysts to determine if the current TAS will meet the needs of the new features (Option A). While Business Analysts provide valuable insights into business requirements and the intended functionality of new features, their feedback may not directly inform the technical suitability or readiness of the TAS to handle these new features. Instead, the TAE should focus on technical evaluations such as reviewing existing keywords for necessary modifications (Option B), running existing automated tests against the updated SUT to identify any changes in operation (Option C), and assessing compatibility with existing test tools or identifying alternative solutions (Option D). These actions directly address the technical implications of new features on the TAS, ensuring that the automated testing remains effective and aligned with the evolving requirements of the SUT.

 When designing a Test Automation Architecture (TAA), it is crucial to ensure that all interfaces of the System Under Test (SUT) that are affected by the tests can be controlled by the TAA. This control allows for the execution of test cases, the simulation of various conditions under which the SUT operates, and the verification of the SUT’s behavior under test. The ability to control these interfaces ensures that the automated tests are effective and can interact with the SUT as required.

References = The ISTQB Test Automation Engineer syllabus outlines the importance of control over the SUT interfaces in the context of test automation. It discusses the technical considerations for the SUT when designing a TAA, including the need for interfaces to be controllable to enable effective and efficient automated testing1.

The gTAA structure is designed to organize the test automation process into distinct layers, each with specific responsibilities:

• a. Test generation layer (3): This layer is responsible for designing test directives that allow configuring the algorithms used to automatically produce the test cases for a given model of the System Under Test (SUT). It involves the creation of models from which test cases can be generated.
• b. Test definition layer (4): This layer allows the definition and implementation of test cases and data by means of templates and/or guidelines. It’s where test cases are articulated and documented.
• c. Test execution layer (2): This layer allows the automated test scripts on an abstract level to interact with components, configurations, and interfaces of the SUT. It’s the practical application of the defined test cases against the SUT.
• d. Test adaptation layer (1): Although not explicitly mentioned in the question, the test adaptation layer is implied as the fourth layer. It acquires all the necessary resources before each test and releases all after the run to avoid interdependencies between tests. This ensures that each test is self-contained and does not affect subsequent tests.

References = The information provided is based on the ISTQB Test Automation Engineer syllabus and the principles of the gTAA structure as outlined in the ISTQB certification materials123.

When a Test Automation System (TAS) uses dedicated test interfaces added to the APIs of a System Under Test (SUT), one specific risk is the occurrence of false alarms during testing. These are test failures that do not necessarily signify defects in the SUT but are caused by the test interfaces or the test environment itself. Such false positives can lead to wasted effort in investigating non-issues and can obscure genuine defects, thus posing a significant risk to the accuracy and efficiency of the testing process.

References = The ISTQB Test Automation Engineer syllabus discusses the importance of evaluating risks associated with the test automation environment and tools. It highlights the need to analyze deployment risks and identify technical issues that could lead to failure of the test automation project, including the risk of false positives due to dedicated test interfaces123.

When planning the pilot for an in-house developed Test Automation Solution (TAS), it is essential to conduct training workshops for new users (Option C) and develop a detailed project plan while reserving the necessary budget and resources (Option D). Training workshops ensure that the users are adequately prepared to use the TAS effectively, contributing to the success of the pilot by minimizing user-related issues and enhancing the adoption rate. A comprehensive project plan with allocated budget and resources establishes a structured framework for the pilot, ensuring that all necessary aspects, such as objectives, scope, timeline, and success criteria, are clearly defined and understood. These steps are critical in preparing the organization for the pilot, mitigating risks, and setting a clear path toward evaluating the TAS's effectiveness and potential benefits for the organization.

Automated exploratory testing is challenging because it relies heavily on human intuition, experience, and real-time decision-making, which are difficult to replicate with automated systems. While test automation offers many advantages, such as repeatability and efficiency, it lacks the creativity and adaptability of a human tester exploring the software without predefined scripts or scenarios. This limitation can be significant, especially when the goal is to discover new and unexpected issues within the system under test.

References = The ISTQB CT-TAE materials discuss the objectives, advantages, disadvantages, and limitations of test automation, acknowledging that while automation can significantly enhance testing efficiency, certain aspects like exploratory testing are better suited for manual execution12.

The business case for the pilot project set a very ambitious target: reducing the execution time by 90% for all tests in the regression suite. However, at the end of the pilot, only 40% of the tests were automated with a 60% reduction in execution time. This indicates that the initial target may have been unrealistic within the given timeframe and resources. It’s important for business cases to set achievable goals to ensure that the project can meet its objectives and provide a clear return on investment. Setting realistic targets also helps maintain stakeholder confidence and support for the project. References = The ISTQB Test Automation Engineer syllabus and related materials discuss the importance of realistic planning and setting achievable targets in the context of test automation projects. These resources emphasize that while test automation can significantly improve efficiency, the extent and speed of these improvements must be realistically assessed based on the specific context of the project12345.

The best time to consider legal and/or standard requirements for a System Under Test (SUT) is when developing a Test Automation Solution (TAS) (Option D). Legal and standard requirements often dictate specific testing protocols, data handling procedures, and compliance checks that must be integrated into the testing process. By considering these requirements during the TAS development phase, the automation framework can be designed to incorporate necessary compliance checks, data protection measures, and other regulatory obligations. This proactive approach ensures that the TAS not only effectively tests the functionality and performance of the SUT but also ensures compliance with relevant legal and industry standards, thereby mitigating the risk of legal challenges and enhancing the quality assurance process.

In this scenario, where the main goal is to verify the compatibility of the automation tool with the application and its ability to recognize objects and controls, capture-replay scripting would be the most suitable technique. This approach allows you to record manual test cases as they are performed in the browser and then replay them automatically. It’s a quick way to convert manual tests into automated ones without requiring extensive programming knowledge. Capture-replay tools can help validate that the tool can interact with the application as expected and identify any potential issues with object recognition.

References = The ISTQB Test Automation Engineer syllabus covers the different scripting techniques and their appropriate usage scenarios. For a detailed understanding of capture-replay scripting and its benefits for initial automation efforts, refer to the official ISTQB Test Automation Engineer documents and training resources12.

For any significant automation project, a critical success factor is that the System Under Test (SUT) must be designed for testability (Option C). Testability refers to the ease with which a system can be tested, which includes aspects like accessibility to test interfaces, observability of outputs, controllability of inputs, and the system's ability to be put into a known state for testing. A SUT designed with testability in mind facilitates the creation and execution of automated tests, enhancing the effectiveness, reliability, and coverage of the Test Automation Architecture (TAA). This design consideration directly impacts the efficiency of testing activities, reducing the time and effort required to achieve comprehensive test coverage and identify defects.

 The best internal metric to measure the quality of the Test Automation System (TAS) and the number of problems associated with it would be the defect density within the TAS automation code. This metric provides insight into the robustness and reliability of the automation code itself. A lower defect density indicates higher quality and fewer problems, while a higher defect density may signal the need for improvements in the automation code. This metric is internal because it pertains directly to the quality of the TAS rather than its impact on external processes. References = The ISTQB Test Automation Engineer syllabus and other ISTQB materials emphasize the importance of internal metrics such as defect density to assess the quality and effectiveness of the TAS123.

 In the context of a CRM application with a GUI delivered through Internet Explorer using proprietary Active X and Java controls, keyword-driven scripting is the most suitable technique. This approach separates the test automation code from the test data, allowing for the creation of high-level keywords that represent user actions on the GUI. It is particularly effective in environments where specific commercial automation tools are necessary, as it enables non-technical testers to write automated test cases using a set of predefined keywords. This method enhances the maintainability and reusability of test scripts, making it easier to adapt to changes in the GUI controls or the underlying application.

References = The ISTQB Test Automation Engineer syllabus and materials provide guidance on selecting appropriate scripting techniques based on the characteristics of the application under test and the test automation tools available. It discusses the advantages of keyword-driven scripting in scenarios where rich client capabilities are implemented and specific automation tools are required12.

 Controllability refers to the degree to which a system, such as the System Under Test (SUT), allows inputs to be injected in a controlled manner. When the SUT provides interfaces that can be used to perform actions on it, this characteristic is essential for test automation because it enables the test engineer to manipulate the system’s state and behavior during testing. Controllability is crucial for ensuring that tests can be performed consistently and effectively, as it allows for precise control over the test conditions. References = ISTQB materials define controllability as a key attribute of a testable system. It is discussed in the context of test automation, particularly in relation to the interfaces provided by the SUT that allow for controlled manipulation during testing12.

Linear scripting is the most suitable approach in the described scenario for several reasons:

• Simplicity and Speed: Linear scripting, also known as "record and playback," involves recording steps in a test as they are performed manually on the application under test. This approach is simple and fast to develop, aligning with the need for a solution that is "simple and fast" as mentioned in the question.
• Short-term Use: Given that the maintainability of the scripts is not a concern due to no anticipated changes to the software, the typically high maintenance cost associated with linear scripts is not a drawback in this context. This is because linear scripts can be brittle and may require significant updates if the application changes. However, since the application is a legacy system with no expected changes, this drawback is mitigated.
• Legacy System Context: Legacy systems often have established and stable interfaces, making them less susceptible to the kinds of changes that would typically break linear scripts. This stability makes linear scripting a viable option.
• Infrastructure Migrations: The scripts are intended to verify basic functionality during infrastructure migrations. Linear scripting can effectively capture the end-to-end flow of application usage, ensuring that the basic functionality works as expected after each migration.
• Skill Level Consideration: The Test Analysts have some programming skills but are not necessarily expert programmers. Linear scripting is accessible to individuals with varying levels of programming expertise, making it an inclusive choice that leverages the existing skills of the Test Analysts.

In conclusion, the linear scripting approach aligns with the requirements for simplicity, speed, and suitability for a non-changing legacy system, making it the best choice under the specified conditions.

The first course of action when encountering an object recognition issue with a test automation tool is to collaborate with the development team to see if the object can be modified to be recognizable by the tool. This approach is often the most straightforward and least disruptive to existing test automation frameworks. It maintains the integrity of the test automation strategy while potentially providing a quick resolution to the object recognition problem. References = The ISTQB CT-TAE syllabus emphasizes the importance of addressing test automation issues by working within the existing test framework and collaborating with the development team to resolve issues123. Additionally, industry best practices suggest that modifying the application to be more automation-friendly is a common solution to such problems45.

 The maturity of the test process needs the most attention because it is fundamental to the successful implementation of a Test Automation System (TAS). Given that there is no formal test process and the system has experienced regression defects, focusing on the maturity of the test process will ensure that the test automation is built on a solid foundation. This involves establishing a structured test process that integrates with both the waterfall and agile lifecycle, ensuring that the automated tests are maintainable, reusable, and provide effective coverage. Without a mature test process, the automation efforts may not align with the business requirements and could result in ineffective testing or further regression issues.

References = The ISTQB Test Automation Engineer syllabus and study resources emphasize the importance of a mature test process when implementing test automation. It is essential for ensuring that the automation aligns with the test strategy and provides value to the organization1234.

In the context of testing a major enhancement to an air traffic control user interface with a limited window for regression testing, the best and most cost-efficient approach to mitigate the risk of the test suite not completing overnight is to analyze the regression test suite and remove test coverage duplication and redundancy (Option C). This approach streamlines the test suite by eliminating unnecessary tests, thereby reducing the overall execution time without compromising the test coverage's integrity. It ensures that each test case provides unique value and that the suite as a whole is optimized for efficiency. This method does not require additional resources or environments and leverages the existing test suite and infrastructure, making it a cost-efficient solution to address the potential delay in starting performance and security testing due to extended regression test durations.
