Excellent point. This is exactly why I asked on this forum. Thank you.

Problem is that we are creating a small framework from scratch. To
implement a valid "application as a test" approach, the framework would have
to already exist. This is why I was discussing unit tests as specification,
not validation.

Once the framework is done, many apps will be based on it and I'm sure that
defects will be found.

Can we close the loop in another way? By emphasizing that unit tests can be
changed by the implementing team?

That isn't going to happen. Let's look for alternatives.

That's the core of the advice I'm taking away. Any followup to my comments?
