When writing test cases, it would be very helpful to be able to run the test case with cached API calls. For example, if you need to debug into the output code for your test, having to re-run the whole test and make API calls is slow, costly and unnecessary. It would be helpful if you could used a cached result so that instead of making a live call to an LLM, it simply returns the cached value. This would allow you to quickly reach the output code.
