POSTMAN-即使对于错误的响应数据，也会通过架构验证

Question

tests["Valid schema"] = tv4.validate(jsonData, schema); is passed even if "error" and "responseType" is missing in the schema. How to make sure that response and schema both are matching for JSON schema.

when I hit post request on postman, the following is the Response Body in postman

{  
  "statusCode": 400,
  "error": "Bad Request",
  "message": "Email/Phone number not found",
  "responseType": "EMAIL_NOT_FOUND",
  "arabicMessage": "البريد الإلكتروني / رقم الهاتف غير موجود"
  }

Tests in Postman

var jsonData=JSON.parse(responseBody)
var schema ={
    "statusCode": {"type":"integer"},
    "message": {"type":"string"},
    "arabicMessage":{"type":"string"},
    "data": {
        "accessToken": {"type":"string"},
        "userDetails": {
            "_id": {"type":"string"},
            "deviceType": {"type":"string"},
            "countryCode": {"type":"string"},

            "address":{"type":"string"},
            "phoneVerified": {"type":"boolean"},
            "currentLocation": {
                "type": "Point",
                "coordinates": [
                   {"type":"integer"},
                   {"type":"integer"}
                ]
            },
            "appVersion": {"type":"integer"},
            "profilePicURL": {
                "thumbnail": {"type":"string"},
                "original": {"type":"string"}
            },

            "phoneNo": {"type":"integer"},
            "email": {"type":"string"},
            "LastName": {"type":"string"},
            "firstName": {"type":"string"},
            "__v": {"type":"integer"},
            "referralCode":  {"type":"string"},
            "accessToken": {"type":"string"},
            "deviceToken":  {"type":"string"}
        },
        "updateAvailable": {"type":"boolean"},
        "stateCallBookingIds":  {"type":"array"},
        "forceUpdate": {"type":"boolean"}
    }
 };
tests["Valid schema"] = tv4.validate(jsonData, schema);
//here the test is passing even with invalid jsonData which is the data                       
 console.log("Validation failed: ", tv4.error);

Answer 1

There are lots of open issues on the Postman github account about the tv4 module.

There is a similar question on SO here , could your jsonData be different than your schema?

This is an example from a link on the tv4 github page.

"title": "Person",
"type": "object",
"properties": {
    "firstName": {
        "type": "string"
    },
    "lastName": {
        "type": "string"
    },
    "age": {
        "description": "Age in years",
        "type": "integer",
        "minimum": 0
    }
},
"required": ["firstName", "lastName"]
}

You could try adding those fields as required ?

Answer 2

Just leaving this here in case it helps anyone else. tv4.validate has two additional boolean parameters: checkRecursive and banUnkownProperties .

Especially the last one can help finding errors in JSON responses when they contain attributes that weren't defined in the schema.
