The error part.inside

user: the script can change it: the error says what happened in the experiment’s names, and what to write instead.

On the refusal list: no test names this code, since no file under tests/ names it. A test may still raise it without naming it, and none asserts it: what its message and action say is read from the source below. The hook that records which codes a test raises has not landed, so until it does the list says names and never raises. The list (docs/ratchets/refusal_codes.txt) only shrinks.

Where MIME gives it, with what its message says happened and what its action says to do ({…} is filled in from the experiment):

• in mime/build/_plan.py:

  • what happened: body {…}'s part {…} lies inside {…}, which is not another part of the body that lies inside none

  • what to do: name in inside= a part that lies inside none. {…}

• in mime/build/_plan.py:

  • what happened: {…}: inside={…} is not a part's name

  • what to do: name in inside= the part it lies inside: Part(..., inside="shell")
