Python使用pytest实现接口自动化的框架代码示例

好的，以下是一个简单的使用pytest实现接口自动化的框架代码示例：

import pytest
import requests

@pytest.fixture()
def api_url():
    return "https://jsonplaceholder.typicode.com"

def test_get_users(api_url):
    response = requests.get(api_url + "/users")
    assert response.status_code == 200
    assert len(response.json()) > 0

def test_get_user(api_url):
    response = requests.get(api_url + "/users/1")
    assert response.status_code == 200
    assert response.json()["name"] == "Leanne Graham"

def test_create_user(api_url):
    new_user = {
        "name": "John Doe",
        "email": "johndoe@example.com",
        "username": "johndoe",
        "address": {
            "street": "123 Main St",
            "suite": "Apt 4",
            "city": "Anytown",
            "zipcode": "12345-6789",
            "geo": {
                "lat": "40.1234",
                "lng": "-73.5678"
            }
        },
        "phone": "555-1234",
        "website": "http://example.com",
        "company": {
            "name": "Example Inc.",
            "catchPhrase": "Making examples since 1999",
            "bs": "Software development"
        }
    }
    response = requests.post(api_url + "/users", json=new_user)
    assert response.status_code == 201
    assert response.json()["name"] == "John Doe"

这个例子中，我们使用了pytest的fixture机制来传递API的基础URL。然后，我们编写了三个测试用例来测试获取用户列表、获取单个用户和创建用户功能。每个测试用例都使用requests库发送API请求，并对响应进行断言，以确保API响应符合预期。使用pytest可以更加方便地组织和运行测试用例，并且能够自动生成测试报告等辅助功能。
