Which of the following are static techniques?

A walkthrough is indeed a static technique because it involves reviewing and examining documents or code without executing them. During a walkthrough, team members or stakeholders come together to discuss and understand the material, which allows for the identification of potential issues or areas of improvement before any actual testing or execution occurs. This technique focuses on gathering feedback and ensuring that the content is clear, complete, and meets its requirements without engaging in the dynamic execution of the software.

In contrast, techniques like state transition testing, decision table testing, and statement testing involve dynamic behaviors of the application or system being tested, where the software is executed to validate its functionality against the defined test cases. These testing methods are carried out in a runtime environment, aiming to assess how the system behaves under various conditions, rather than analyzing the documents or code statically.
