Contract
- assert the test conn is an in-process struct with a fabricated loopback peer, and that the deprecated conn.owner field is nil because the owning pid lives in the adapter payload
- assert conn.status is nil and conn.state is :unset before the router runs, and 200/:sent after
- assert sent_resp reports a sent response and raises for one that resp/3 only staged
- assert a route binds its path segment as a variable in the route body
- assert an unmatched path is 404 only because match _ exists, and a router without it raises FunctionClauseError
- assert the method is part of the match, so a POST to a GET route falls through to 404
- assert Plug.Parsers is what turns a JSON body into conn.body_params, and that params merges the query string while body_params does not
- assert a top-level JSON array arrives under the _json key
- assert that without Plug.Parsers body_params stays Plug.Conn.Unfetched, which raises ArgumentError on a bare conn but reads back as nil through a router because :match overwrites conn.params
- assert a content type listed in :pass reaches a route unparsed with body_params still the Unfetched placeholder, while one in neither :parsers nor :pass raises Plug.Parsers.UnsupportedMediaTypeError
- assert a map body passed to conn/3 is written straight into body_params as multipart/mixed, skipping the parser entirely, and that read_body returns a placeholder
- assert send_resp and put_resp_header raise Plug.Conn.AlreadySentError once the response is sent
- assert put_resp_content_type appends charset=utf-8 and stores a lowercase header name that get_resp_header matches exactly
