常见的想当然
A caller can treat json.Encoder.Encode as json.Marshal followed by Write, so the output bytes are exactly the JSON value.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- assert that json.NewEncoder(&buf).Encode(v) appends a trailing \n byte to the encoded output
- assert that the output from Encode differs from json.Marshal(v) exactly by that newline
