In my opinion, it is a bad practice when the code depends on the implementation of the tests.

ok，I will find a way. @vkd There are other ways to bypass the cover detection ?

Add some test code to the official code, someone has done this, such as rsc, in the standard library. So, I don't think this piece needs to be modified.

In your example, there is the different case, because the behavior of a method does not change.

I think better approach is to do it like in go default json.Decode. For reason to save the same behaviour.

@vkd Is this code?
case reflect.Slice:
if v.Type().Elem().Kind() != reflect.Uint8 {
d.saveError(&UnmarshalTypeError{Value: "string", Type: v.Type(), Offset: int64(d.readIndex())})
break
}
b := make([]byte, base64.StdEncoding.DecodedLen(len(s)))
n, err := base64.StdEncoding.Decode(b, s)
if err != nil {
d.saveError(err)
break
}
v.SetBytes(b[:n])There was a problem hiding this comment.
This code may not be used. In json, []byte data is encoded by base64, so it needs to be decoded by base64.StdEncoding.Decode function. But http is not encoded in base64.

Please fix the conflicts and move to 1.11 |

Okay, I'll set aside time on Saturday to fix it. |
