Exit criteria typically may consist of which of the following?

Exit criteria are essential elements that help determine whether testing can be considered complete. They typically outline the conditions that must be fulfilled before concluding the testing phase of a project. One significant aspect of exit criteria includes specific measures related to the quality and performance of the software, such as estimates of defect density or reliability measures.

Defect density refers to the number of confirmed defects divided by the size of the software entity, which helps gauge the quality of the software. Reliability measures provide insight into how well the software performs under various conditions and over time. These metrics give stakeholders a clear understanding of the software's readiness for release, ensuring that it meets the required quality standards.

The other choices represent other important aspects of the testing process but do not directly relate to the criteria for determining when testing can be considered complete. The choice relating to templates for test documentation and the adequacy of test approaches focuses more on the process rather than the measurements of quality itself. Discussions on disaster recovery are indeed critical for software development but pertain more to overall project risk management rather than the specific exit criteria for testing.
