💡 Hint

Common Mistakes

Using 201 which means created, not OK.

Using 404 which means not found.

Using 500 which means server error.

The status code 200 means the request was successful. We check this with pm.response.to.have.status(200).

2fill in blank

medium

Complete the code to check if the JSON response has a property named 'userId'.

Postman

pm.test('Response has userId', function () { pm.expect(pm.response.json()).to.have.property([1]); });

Drag options to blanks, or click blank then click option'

A'name'

B'id'

C'userId'

D'email'

💡 Hint

Common Mistakes

Using property names that do not exist in the response.

Forgetting to put quotes around the property name.

We check if the JSON response has the property userId by passing its name as a string to have.property.

3fill in blank

hard

Fix the error in the code to correctly validate the response JSON schema.

Postman

const schema = [1];
pm.test('Schema is valid', function () { pm.response.to.have.jsonSchema(schema); });

Drag options to blanks, or click blank then click option'

D{ type: 'object', properties: { id: { type: 'number' } }, required: ['id'] }

💡 Hint

Common Mistakes

Using a string instead of an object for the schema.

Using null or numbers instead of a schema object.

The schema must be a valid JavaScript object describing the JSON structure. Option D is correct syntax.

4fill in blank

hard

Fill both blanks to check that the response JSON has a 'name' property of type string.

Postman

const schema = { type: 'object', properties: { name: { type: [1] } }, required: [[2]] };
pm.test('Name property is string', function () { pm.response.to.have.jsonSchema(schema); });

Drag options to blanks, or click blank then click option'

A'string'

B'name'

C'number'

D'id'

💡 Hint

Common Mistakes

Using 'number' instead of 'string' for the type.

Forgetting to put quotes around the required property name.

The property 'name' should be of type 'string' and must be required, so the required array includes 'name'.

5fill in blank

hard

Fill all three blanks to validate a response JSON with 'id' as number, 'email' as string, and both required.

Postman

const schema = {
  type: 'object',
  properties: {
    id: { type: [1] },
    email: { type: [2] }
  },
  required: [[3]]
};
pm.test('Validate id and email', function () {
  pm.response.to.have.jsonSchema(schema);
});

Drag options to blanks, or click blank then click option'

A'number'

B'string'

C'id', 'email'

D'email'

💡 Hint

Common Mistakes

Putting the required properties without quotes or as separate strings.

Mixing up the types for id and email.

The 'id' property type is 'number', 'email' is 'string', and both are required, so the required array includes both 'id' and 'email' as strings.
