How did you test the backend and REST API?

For testing backend and REST API, I used several approaches:

• Manual testing with tools like Postman or Insomnia to verify the correctness of responses, status codes, headers, and response body.

• Automated testing using frameworks such as pytest with the requests library to write tests that check various API scenarios.

• Integration testing to ensure that interactions between backend components work correctly.

• Load testing with tools like JMeter or Locust to evaluate API performance and stability under load.

• Schema validation using JSON Schema or OpenAPI specifications to ensure data format compliance.

Here's a simple example of a Python test using requests and pytest:

import requests

def test_get_user():
    response = requests.get('https://api.example.com/users/1')
    assert response.status_code == 200
    data = response.json()
    assert 'id' in data and data['id'] == 1
    assert 'name' in data
