Function TestToHTTPHeader_AcceptListValue_FoldedSingleHeader

pkg/util_test.go:890–903

TestToHTTPHeader_AcceptListValue_FoldedSingleHeader pins the wire behaviour that the duplicate-Accept TypeError fix depends on: an axios-style `Accept: application/json, text/plain, */*` mock must replay as ONE wire header so server middlewares using `dict(**request.headers)` do not see duplicate `a

(t *testing.T)

// replay as ONE wire header so server middlewares using
// `dict(**request.headers)` do not see duplicate `accept` keys.
