Designing the System Under Test (SUT) for testability is important for a good test automation...

 The concept of reusability is not a primary consideration when designing a System Under Test (SUT) for testability. Testability focuses on the ease with which a system can be tested. This includes how well the system can be observed and controlled during testing, and whether its architecture supports testing on all levels. While reusability of code is a beneficial attribute in software development, it does not directly impact the testability of the SUT. Testability is more concerned with observability, controllability, and the clarity of the architecture to facilitate effective and efficient testing. References = The ISTQB Test Automation Engineer syllabus and study materials emphasize the importance of designing an SUT for testability to ensure that automated tests can be performed effectively. These resources outline key considerations such as observability, controllability, and a clearly defined architecture, which are essential for test automation12345.
