Which are the TWO most appropriate examples of entry criteria documented in the system integration test plan?

The identification of entry criteria is vital in ensuring that the system is ready for the next phase of testing. In the context of system integration testing, entry criteria define the minimum requirements or conditions that must be met before testing can begin.

One of the appropriate examples of entry criteria is the percentage of decision coverage achieved during unit testing. Achieving a specific level of decision coverage is crucial because it indicates that the unit tests have adequately exercised the various paths in the code. This ensures that the system components are functioning correctly before they are integrated with other parts of the system. This focus on coverage metrics helps mitigate the risk of issues arising from components that have not been sufficiently tested at the unit level, yielding a more stable environment for integration testing.

The other options, while related to testing activities, do not directly address the prerequisites needed before beginning system integration testing. The availability of tools, sign-offs for software releases, and scheduled acceptance test procedures may contribute to the overall testing process but are not fundamental conditions that need to be satisfied before starting the integration tests.
