帮我写一套企业般的Httprunner测试框架整体代码

当然，以下是一个简单的企业级Httprunner测试框架的整体代码示例：

# conftest.py
import pytest
from py.xml import html
from datetime import datetime


@pytest.mark.optionalhook
def pytest_html_results_summary(prefix, summary, postfix):
    prefix.extend([html.p("测试执行时间：%s" % datetime.now())])


# tests/conftest.py
import pytest
from httprunner import HttpRunner


@pytest.fixture(scope="session")
def prepare_session(request):
    # 在测试会话开始前执行的操作
    runner = HttpRunner()
    runner.run("path/to/suite.yml")
    request.config.cache.set("runner", runner)


@pytest.fixture(scope="function")
def prepare_function(request):
    # 在每个测试用例执行前执行的操作
    runner = request.config.cache.get("runner")
    testcase = runner.testcase_parser.get_testcase(request.node.name)
    testcase["variables"]["env"] = "test"
    testcase["variables"]["token"] = "xxx"
    runner.run_testcase(testcase)


# tests/test_example.py
def test_example(prepare_session, prepare_function):
    pass


# tests/test_another_example.py
def test_another_example(prepare_session, prepare_function):
    pass


# test_suite.yml
config:
  name: "Example Test Suite"
  variables:
    - env: ""
    - token: ""

testcases:
  - name: "Example Test Case"
    variables:
      - env: "${env}"
      - token: "${token}"
    request:
      url: "http://example.com/api/endpoint"
      method: "POST"
      headers:
        Content-Type: "application/json"
      json:
        key: value
      validate:
        - eq: [status_code, 200]
        - eq: [body.success, true]

以上是一个简单的企业级Httprunner测试框架的代码示例。你可以根据实际需求进行适当的修改和扩展，包括配置、测试用例、前置后置处理等部分。
