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

In the context of system integration testing, entry criteria are specific conditions that must be met before testing can begin. These criteria help ensure that the test environment is ready, and the necessary components and tools are in place to conduct effective testing.

The decision coverage achieved during unit testing is a valid example of entry criteria because it indicates that the unit tests have sufficiently covered the various decisions within the code. A high percentage of decision coverage suggests that the units have been tested thoroughly, thus reducing the likelihood of defects during integration testing. This is essential as system integration testing often builds upon the results of unit testing, and having solid unit testing results helps ensure that the components being integrated are well-prepared.

In examining other options, while availability of testing tools is important, it doesn't guarantee the readiness of the components being tested. Similarly, performance test software release notes and scheduled acceptance test procedures are related to different phases of testing or may indicate preparedness for subsequent testing cycles rather than serving as a direct entry requirement for integration tests. Therefore, the percentage of decision coverage achieved during unit testing directly relates to the readiness of the software components for integration, making it a strong candidate for entry criteria.
