Unable to validate complete JSON schema using tv4 - arrays

Question

Total newb here.
I'm wondering if someone can help because i'm at a loss! I'm trying to assert that the response from a GET API Call meets this monster schema set - Using console.log() it looks like each of the properties is accessed successfully and if i change the object type the test will fail as i'd expect.
Working down the schema - If i try and change a property in the data array i.e from string to boolean the test will still pass although it doesn't meet the required schema i've defined,
Any guidance is massively appreciated!
//Test the schema is valid

// Use tiny validator to validate the results - Error if there are additional properties, and check recursion.
pm.test("Validate schema contains the relevant details", () => {
tv4.validateMultiple(jsonData, schema, true, true);
var jsonData = JSON.parse(responseBody);
// Log all errors to the console
var validationResult = tv4.validateMultiple(jsonData, schema, true, true);
for (var i = 0; i < validationResult.errors.length; i++) {
console.log("path :" + validationResult.errors[i].dataPath + " message :" + validationResult.errors[i].message);
}
});

Answer 1

const schema = {
"type": "object",
"properties": {
"current_page": {
"type": "boolean"
}
}
}
pm.test("Validate schema contains the relevant details", () => {
var jsonData = { "current_page": 2 }
// Log all errors to the console
var validationResult = tv4.validateMultiple(jsonData, schema, true, true);
validationResult.valid ? null : console.log(JSON.stringify(validationResult, null, 2))
pm.expect(validationResult.valid, JSON.stringify(validationResult, null, 2)).to.be.true
});
you don't have expect to assert it that's why it passes always , also as Danny mentioned use
const schema = {
"type": "object",
"properties": {
"current_page": {
"type": "boolean"
}
}
}
pm.test("Validate schema contains the relevant details", () => {
var jsonData = { "current_page": 2 }
pm.response.to.have.jsonSchema(schema)
});
And for array you should use items instead of property:
const schema = {
"type": "object",
"properties": {
"data": {
"type": "array",
"items": {
"properties": {
"id": {
"type": "integer"
},
"name": {
"type": "string"
}
},
"required":["id","name"]
}
}
}
}
pm.test("Validate schema contains the relevant details", () => {
var jsonData = { "data": [{ "id": 2,"name":"test" }] }
// Log all errors to the console
var validationResult = tv4.validateMultiple(jsonData, schema, true, true);
validationResult.valid ? null : console.log(JSON.stringify(validationResult, null, 2))
pm.expect(validationResult.valid, JSON.stringify(validationResult, null, 2)).to.be.true
});
you can create schema with so much ease using :
