httprunner用例结构(前后置)

说���：httprunner 结合 pytest 的前后置方式

1. 用例级别前后置

1.1. setup teardown

class TestCaseRefTestcase(HttpRunner):    # 用例级别前后置    def setup(self):        logger.warning("------用例级别前置")    def teardown(self):        logger.warning("------用例级别后置")    config = (        Config("request methods testcase: reference testcase")        .variables(            **{                "foo1": "testsuite_config_bar1",                "expect_foo1": "testsuite_config_bar1",                "expect_foo2": "config_bar2",            }        )        .base_url("https://postman-echo.com")        .verify(False)    )    teststeps = [        Step(            RunTestCase("request with functions")            .with_variables(                **{"foo1": "testcase_ref_bar1", "expect_foo1": "testcase_ref_bar1"}            )            .call(Requests)            .export(*["foo3"])        ),        Step(            RunRequest("post form data")            .with_variables(**{"foo1": "bar1"})            .post("/post")            .with_headers(                **{                    "User-Agent": "${get_user_agent()}",                    "Content-Type": "application/x-www-form-urlencoded",                }            )            .with_data("foo1=$foo1&foo2=$foo3")            .validate()            .assert_equal("status_code", 200)            .assert_equal("body.form.foo1", "bar1")            .assert_equal("body.form.foo2", "bar21")        ),    ]if __name__ == "__main__":    TestCaseRefTestcase().test_start()

2. 类级别前后置

2.1. setup_class

    def setup_class(self):        logger.warning("------类级别前置")

2.2. teardown_class

    def teardown_class(self):        logger.warning("------类级别后置")

3. 模块级别前后置

3.1. conftest.py

import uuidfrom typing import Listimport pytestfrom httprunner import Config, Stepfrom loguru import logger@pytest.fixture(scope="session", autouse=True)def session_fixture(request):    """setup and teardown each task"""    logger.warning(f"-------conftest模块级别前置---------")    total_testcases_num = request.node.testscollected    testcases = []    for item in request.node.items:        testcase = {            "name": item.cls.config.name,            "path": item.cls.config.path,            "node_id": item.nodeid,        }        testcases.append(testcase)    logger.debug(f"collected {total_testcases_num} testcases: {testcases}")    yield    logger.debug(f"teardown task fixture")    logger.warning(f"-------conftest模块级别后置---------")    # teardown task    # TODO: upload task summary@pytest.fixture(scope="function", autouse=True)def testcase_fixture(request):    """setup and teardown each testcase"""    logger.warning(f"-------conftest函数级别前置---------")    config: Config = request.cls.config    teststeps: List[Step] = request.cls.teststeps    logger.debug(f"setup testcase fixture: {config.name} - {request.module.__name__}")    def update_request_headers(steps, index):        for teststep in steps:            if teststep.request:                index += 1                teststep.request.headers["X-Request-ID"] = f"{prefix}-{index}"            elif teststep.testcase and hasattr(teststep.testcase, "teststeps"):                update_request_headers(teststep.testcase.teststeps, index)    # you can update testcase teststep like this    prefix = f"HRUN-{uuid.uuid4()}"    update_request_headers(teststeps, 0)    yield    logger.warning(f"-------conftest函数级别前置---------")    logger.debug(        f"teardown testcase fixture: {config.name} - {request.module.__name__}"    )    summary = request.instance.get_summary()    logger.debug(f"testcase result summary: {summary}")

4. 优先级顺序效果展示
