com.fasterxml.jackson.core.JsonParseException: Unrecognized token

[Cema N]

Hi,

I'm using to Wiremock to mock my response.

My Json Schema and Json body is as below:

Json Schema:

{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "title": "Product set",
    "items": {
        "title": "product",
        "type": "object",
        "properties": {
            "productId": {
                "type": "number"
            },
            "productName": {
                "type": "string"
            },
            "productPrice": {
                "type": "number",
                "minimum": 0
            },
            "dimensions": {
                "type": "object",
                "properties": {
                    "length": {"type": "number"},
                    "width": {"type": "number"},
                    "height": {"type": "number"}
                }
            }
        },
        "required": ["productId", "productName"]
    }
}

Json Body:


                        "product":{
                            "productId":"5",
                            "productName":"Television",
                            "productPrice":1200,
                            "dimensions":[{
                            "length":35,
                            "width":50,
                            "height":45
                            }]
}
}

I have validated the Json body with schema with an online available validator and body conforms to schema.

I'm using below code to send the response and Json schema as string, where content contains the schema.

assertThat(response.toString(), matchesJsonSchema((content)));


But while I try to assert against schema i get the below error:

io.restassured.module.jsv.JsonSchemaValidationException: com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'com': was expecting ('true', 'false' or 'null')

Kindly advise.

Hi Johan,

Thank you the reply. I have attached both JSON schema and body the question itself. I have also pasted the json file am using for wiremock.
Let me know what I may be missing:

{
    "request": {
            "method": "GET",
            "url": "/test/GETJsonSchemaValidation"
    },
    "response": {
            "status": 200,
            "headers": {
                    "Content-Type": "application/json"
            },
            "jsonBody" : {

                        "product":{
                            "productId":"5",
                            "productName":"Television",
                            "productPrice":1200,
                            "dimensions":[{
                            "length":35,
                            "width":50,
                            "height":45
                            }]
}
}
    }
}

Thanks,
Cema

What is the JSON you want to validate? Your schema doesn't seem to take all of those properties into account? 

I've tried http://www.jsonschemavalidator.net/ and if I pass in your schema and the JSON:

{
                            "productId":"5",
                            "productName":"Television",
                            "productPrice":1200,
                            "dimensions":[{
                            "length":35,
                            "width":50,
                            "height":45
                            }]}

which I suspect is what you're trying to validate it works. This also works when I try it in REST Assured:

assertThat("{ \"productId\":\"5\",\n" +
                "                            \"productName\":\"Television\",\n" +
                "                            \"productPrice\":1200,\n" +
                "                            \"dimensions\":[{\n" +
                "                            \"length\":35,\n" +
                "                            \"width\":50,\n" +
                "                            \"height\":45\n" +
                "                            }]\n" +
                "    }", JsonSchemaValidator.matchesJsonSchema("\n" +
                "{\n" +
                "    \"$schema\": \"http://json-schema.org/draft-04/schema#\",\n" +
                "    \"title\": \"Product set\",\n" +
                "    \"items\": {\n" +
                "        \"title\": \"product\",\n" +

                "            },\n" +
                "            \"productName\": {\n" +
                "                \"type\": \"string\"\n" +
                "            },\n" +
                "            \"productPrice\": {\n" +
                "                \"type\": \"number\",\n" +
                "                \"minimum\": 0\n" +
                "            },\n" +
                "            \"dimensions\": {\n" +

                "                    \"length\": {\"type\": \"number\"},\n" +
                "                    \"width\": {\"type\": \"number\"},\n" +
                "                    \"height\": {\"type\": \"number\"}\n" +
                "                }\n" +
                "            }\n" +
                "        },\n" +
                "        \"required\": [\"productId\", \"productName\"]\n" +
                "    }\n" +
                "}"));

Thank you Johan. I was passing the response as a string using response.toString. I changed it to response.prettyPrint() and it worked.

Thanks again as i was stuck with this for 3 days now.

Cema

Ah ok, I can see that it is confusing. You could probably change it to "asString()" instead to avoid pretty printing to the console.

Thank you Johan. "asString()" worked like a charm.
