JSON Schema Validation with REST-assured - assert values not in json schema - json

Is there a way how to assert that API response contains values which are NOT in JSON schema? (e.g.: "name": "Nick")
API response example (name is not specified in schema below):
{
"id": "390",
"name": "Nick",
"data": {
"leagueId": 35,
"homeTeam": "Norway",
"visitingTeam": "England",
}
}
JSON schema:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"properties": {
"id": {
"type": "string"
},
"data": {
"type": "object",
"properties": {
"leagueId": {
"type": "integer"
},
"homeTeam": {
"type": "string"
},
"visitingTeam": {
"type": "string"
}
},
"required": [
"leagueId",
"homeTeam",
"visitingTeam"
]
}
},
"required": [
"id",
"data"
]
}
Comparison code example:
#Test
public void givenUrl_whenValidatesResponseWithInstanceSettings_thenCorrect() {
JsonSchemaFactory jsonSchemaFactory = JsonSchemaFactory.newBuilder()
.setValidationConfiguration(
ValidationConfiguration.newBuilder()
.setDefaultVersion(SchemaVersion.DRAFTV4).freeze())
.freeze();
get("/events?id=390").then().assertThat()
.body(matchesJsonSchemaInClasspath("event_0.json")
.using(jsonSchemaFactory));
}

Json schema validation for object which may have two forms

I'm trying to figure out how to validate a JSON object which may have 2 forms.
for examples
when there is no data available, the JSON could be
{
"student": {}
}
when there is data available, the JSON could be
{
"student":{
"id":"someid",
"name":"some name",
"age":15
}
}
I wrote the JSON schema in this way, but it seems not working
{
"$schema": "http://json-schema.org/draft-07/schema#",
"$id": "http://json-schema.org/draft-07/schema#",
"title": "JSON schema validation",
"properties": {
"student": {
"type": "object",
"oneOf": [
{
"required": [],
"properties": {}
},
{
"required": [
"id",
"name",
"age"
],
"properties": {
"id": {
"$id": "#/properties/student/id",
"type": [
"string",
"null"
]
},
"name": {
"$id": "#/properties/student/name",
"type": [
"string",
"null"
]
},
"age": {
"$id": "#/properties/student/age",
"type": [
"number"
]
}
}
}
]
}
}
}
I was wondering is there a way to validate it. Thank you!
An empty properties object, and an empty required object, do nothing.
JSON Schema is constraints based, in that if you don't explicitly constrain what is allowed, then it is allowed by default.
You're close, but not quite. The const keyword can take any value, and is what you want in your first item of allOf.
You can test the following schema here: https://jsonschema.dev/s/Kz1C0
{
"$schema": "http://json-schema.org/draft-07/schema",
"$id": "https://example.com/myawesomeschema",
"title": "JSON schema validation",
"properties": {
"student": {
"type": "object",
"oneOf": [
{
"const": {}
},
{
"required": [
"id",
"name",
"age"
],
"properties": {
"id": {
"type": [
"string",
"null"
]
},
"name": {
"type": [
"string",
"null"
]
},
"age": {
"type": [
"number"
]
}
}
}
]
}
}
}

JSON Schema for child objects with different set of keys

I have JSON data of which is an array of data like
[
{
"type": "background_color",
"data": {
"backgroundColor": "F9192D"
}
},
{
"type": "banner_images",
"data": {
"images": [
{
"url": "https://example.com/abc.jpg",
"id": 3085
},
{
"url": "https://example.com/zyx.jpg",
"id": 3086
}
]
}
},
{
"type": "description_box",
"data": {
"text": "Hello 56787"
}
}
]
The data is an array of object which has two keys type and data. The type and keys of the data will be defined by the type of data it has.
Like for background_color type, the data should have backgroundColor property, while for banner_images, data should have images which is an array of other properties.
Till now, What I have done is
{
"definitions": {},
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "array",
"title": "category schema",
"description": "Used to validate data of category",
"examples": [],
"required": [],
"items": {
"type": "object",
"required": [
"type",
"data"
],
"properties": {
"type": {
"type": "string",
"enum": ["background_color", "banner_images", "description_box"]
},
"data": {
"type": "object" // How to define data property here for each use case
}
}
}
}
I'm not getting how to define the data property for each use case?
You can use if/then/else blocks to define conditional constraints.
The values of if and then are schemas. If the if schema is valid, then the then schema is applied, otherwise, the allOf subschema (allOf[0] in this example) would pass validation.
There are a few different ways to do this, but this is clean when you don't have any additional or special requirements. Please come back if you do =]
In this example, I've added banner_images...
You can test it working here.
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "array",
"title": "category schema",
"description": "Used to validate data of category",
"items": {
"type": "object",
"required": [
"type",
"data"
],
"properties": {
"type": {
"type": "string",
"enum": [
"background_color",
"banner_images",
"description_box"
]
},
"data": {
"type": "object"
}
},
"allOf": [
{
"if": {
"properties": {
"type": {
"const": "banner_images"
}
}
},
"then": {
"properties": {
"data": {
"required": [
"images"
],
"properties": {
"images": {
"type": "array"
}
}
}
}
}
}
]
}
}
For reference, here's the part of the JSON Schema draft-7 spec document that details the behaviour: https://datatracker.ietf.org/doc/html/draft-handrews-json-schema-validation-01#section-6.6

I have a custom connector which returns a JSON response .I am trying to parse the response to JSON since i want to use the response later in other flows. So that I am using Parse JSON Action from Data operations connector. Following is the JSON response and the JSON schema i provided to Parse JSON.

Any one knows what is the issue on this ?How we can I convert above json response
Looks like the Use sample payload to generate schema couldn't generate right schema.
So you could go to this liquid studio site and paste the JSON payload then click the Generate Schema button, then you will get the Json Schema.
And I test the Schema, it worked perfectly.
Hope this could help you, if you still have other questions,please let me know.
Schema looks incorrect. try with the below schema:
{
"type": "array",
"items": [
{
"type": "array",
"items": [
{
"type": "object",
"properties": {
"key": {
"type": "string"
},
"value": {
"type": "object",
"properties": {
"id": {
"type": "string"
},
"name": {
"type": "string"
}
},
"required": [
"id",
"name"
]
}
},
"required": [
"key",
"value"
]
},
{
"type": "object",
"properties": {
"key": {
"type": "string"
},
"value": {
"type": "string"
}
},
"required": [
"key",
"value"
]
}
]
}
]
}

allow one of all based on the same base type

I have the following json schema:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"description": "schema validating people and vehicles",
"definitions": {
"base": {
"properties": {
"age": {
"type": "integer"
}
},
"required": [
"age"
]
},
"person": {
"$ref": "#/definitions/base",
"additionalProperties": false,
"properties": {
"firstName": {
"type": "string"
},
"lastName": {
"type": "string"
},
"sport": {
"type": "string"
}
},
"required": [
"firstName"
]
},
"vehicle": {
"$ref": "#/definitions/base",
"additionalProperties": false,
"properties": {
"vehicle": {
"type": "string"
},
"price": {
"type": "integer"
}
}
}
},
"type": "object",
"oneOf": [
{
"$ref": "#/definitions/person",
},
{
"$ref": "#/definitions/vehicle",
}
]
}
And i want it to validate against
{"firstName":"John", "lastName":"Doe", "sport": "football", "age": 15}
and the following
{"type": "car", "price": 100, "age": 3}
I get the following error JSON is valid against more than one schema from 'oneOf'. Valid schema indexes: 0, 1..
Why is it valid against more then one? (firstName is only defined in person and type is only defined in vehicle.)
JSON Schema doesn't support inheritance.

json schema for dynamic array

I have the following json
{
"Dettype": "QTY",
"Details": [
{
"12568": {
"Id": 12568,
"qty":1,
"Freq":"2",
"Option": 0,
"promote":"yes"
},
"22456": {
"Id": 22456,
"qty":2,
"Freq":"3",
"Option": 1,
"promote":"no"
}
}
]
}
For the above json i need to write a json schema file which will valdiates the request.
but the problem is in array the key value for each item changes dynamically. If it is some constant value i can write but don't how to do the dynamic pattern
JSON schema i got
{
"type": "object",
"additionalProperties": true,
"properties": {
"Dettype": {
"type": "string"
},
"Details": {
"type": "array",
"items": {
"type": "object",
"additionalProperties": true,
"properties": {
"**DYNAMIC VALUE**": {
"type": "object",
"additionalProperties": true,
"properties": {
"Id": {
"type": "integer"
},
"qty": {
"type": "integer"
},
"Freq": {
"type": "string"
},
"Option": {
"type": "integer"
},
"promote": {
"type": "string"
}
}
}
}
}
}
}
}
Can some one tell what changes need to be done for schema
This is what patternProperties is for.
Here it seems your object member keys are always digits; therefore you can write things like this:
"type": "object",
"patternProperties": {
"^\\d+$": {
"type": "object",
"etc": "etc"
}
}
You can also use additionalProperties if you want all properties to match some schema:
{
"type": "object",
"additionalProperties": {
"type": "object",
"etc": "etc"
}
}
