Is there already a clear API for a “test framework” or “interactive
REPL” to declare itself as such?

Do all the test frameworks and interactive REPL implementations already
follow that API?

I ask this to know whether your proposal entails that each
implementation of a test framework or REPL will likely behave
differently from other implementations in how it fits into the above
categories.
