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.

 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.

Confirmation testing, also known as retesting, involves verifying that defects identified during earlier tests have been fixed. The ISTQB guidelines suggest that confirmation tests are suitable candidates for automation because they are often repetitive and need to be run multiple times to confirm that the defect has indeed been fixed and does not reappear in subsequent releases. Automating these tests can save time and resources, and when incorporated into a regression test suite, they can provide continuous feedback on the status of the application under test.

References = The ISTQB Test Automation Engineer syllabus and study materials emphasize the importance of automating confirmation tests as part of a comprehensive test strategy. This includes integrating automated confirmation tests into the regression suite to ensure that previously fixed defects do not reoccur, thus maintaining the integrity of the software over time123.
