* Performance - Does the test method perform well? Will it cause significant slowdown to CI jobs?
* Ease of reproduction - Does the prototype require a particular platform or tool to be set up? How easy would it be for an external user to run the prototype?
* Comprehensibility - Accounting for the lower code quality of a prototype, would developers unfamiliar with the tests based on the prototype be able to understand them easily?
* Portability - How well can this approach be ported to multiple platforms? This would allow us to ensure that there are no double-accesses due to a bug that only affects a specific target.
Once each prototype is complete, choose the best approach to implement the careful-access testing. Implement tests using this approach for each of the PSA interfaces that require careful-access testing:
