1fill in blank

easy

Complete the code to define a contract test that checks the response status code.

Rest API

def test_api_response():
    response = client.get('/api/data')
    assert response.status_code == [1]

Complete the code to check that the response content type is JSON.

Rest API

def test_content_type():
    response = client.get('/api/data')
    assert response.headers['Content-Type'] == [1]

💡 Hint

Common Mistakes

Using text/html which is for web pages

Using application/xml which is for XML data

The API should return data in JSON format, so the content type must be application/json.

3fill in blank

hard

Fix the error in the contract test that verifies the JSON response has a 'name' field.

Rest API

def test_response_has_name():
    response = client.get('/api/user')
    data = response.json()
    assert [1] in data

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

A'name'

B'username'

C'id'

D'email'

💡 Hint

Common Mistakes

Checking for 'username' instead of 'name'

Checking for 'email' which is not required

The contract requires the JSON response to include the 'name' field.

4fill in blank

hard

Fill both blanks to create a contract test that verifies the 'age' field is an integer and greater than 18.

Rest API

def test_age_field():
    response = client.get('/api/user')
    data = response.json()
    assert isinstance(data['age'], [1]) and data['age'] [2] 18

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

💡 Hint

Common Mistakes

Using str instead of int

Using < instead of >

The 'age' field must be an integer and greater than 18 to meet the contract.

5fill in blank

hard

Fill all three blanks to write a contract test that filters users with 'active' status and checks their 'email' contains '@'.

Rest API

def test_active_users_email():
    response = client.get('/api/users')
    users = response.json()
    active_users = [user[1] user in users if user['status'] [2] 'active']
    assert all('[3]' in user['email'] for user in active_users)

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

B==

C@

D!=

💡 Hint

Common Mistakes

Using '!=' instead of '==' for status check

Missing '@' in email check

Incorrect list comprehension syntax

The list comprehension uses for to iterate, == to check status, and '@' to verify emails.
