• assert a constructed Request driven straight through the Router dispatches on method and path with no port bound, that an unregistered method on a matched path is a 404 and not a 405, that a <param> stops at a slash, and that registering GET also registers a HEAD in front of it whose body is stripped but whose content-length still reports the GET body length
• assert a handler taking only a Request receives the captures through the request.params extension getter, backed by a shelf_router/params context key that survives request.change, and that params outside a Router is an empty unmodifiable map rather than null
• assert a handler taking extra arguments is filled positionally in route-pattern order with the closure's parameter names ignored, and that a wrong argument count is accepted at registration and fails as a NoSuchMethodError on the first matching request
• assert the unmatched route returns Router.routeNotFound itself, one shared instance that can be read more than once, that returning it from a handler resumes matching while an identical-looking Response.notFound ends the request, and that notFoundHandler replaces it
• assert Pipeline runs middleware in declaration order inbound and the reverse outbound, proven by a response header each middleware appends to and by one they overwrite where the outermost writer wins, and that middleware answering without calling the inner handler cuts out everything declared below it
• assert a shelf body is single-subscription whether it was passed as a String or as a Stream, that the second read throws StateError synchronously out of readAsString, and that change() shares the drained Body so only change(body: ...) restores it
• assert a logging middleware that reads the response body forwards an unreadable response, that the request-side version breaks the route handler through the router's own request.change, and that both are fixed by putting the read body back
• assert header lookup is case-insensitive on requests and responses while the stored keys keep the case they were written with, and that a request served over loopback arrives with lowercase keys because dart:io lowercases them off the wire
