Question

似乎钩子函数pytest_report_teststatus的拆解部分/触发器在具有yield语句的任何会话范围内的固定装置之后执行。我该如何改变？例如，这是我的钩子函数：

def pytest_report_teststatus(report,): 
    """
    Using the pytest hook pytest_report_teststatus.  This will give us
    the test result of each test function.
    Note, this hook can get called up to 3 times for one test funtion.
    Test Setup, Call, and Teardown.  Call is the actual test function.

    This hook function will write out test results for each
    test to the summary.log file.

    """
    sum_log = dnet_generic.get_logger()
    if report.when == 'setup' and report.outcome == 'failed':
        sum_log.info("\n    --------------------------------------")
        sum_log.info("    ---- Test Setup Stage FAILED!")
        sum_log.info(f'    ---- Test: {report.nodeid}' )
        sum_log.info("    --------------------------------------\n")
    elif report.when == 'call':
        now = datetime.datetime.now()
        end_time = now.strftime('%a %b %d %H:%M:%S %Z %Y')
        sum_log.info("\n    --------------------------------------")
        sum_log.info('    ---- Test Function completed at: %s' % (end_time) )
        sum_log.info(f'    ---- Test: {report.nodeid}' )
        sum_log.info(f'    ---- Result: {report.outcome.upper()}' )
        sum_log.info("    --------------------------------------\n")
    elif report.when == 'teardown' and report.outcome == 'failed':
        sum_log.info("\n    --------------------------------------")
        sum_log.info("    ---- Test Teardown Stage FAILED!")
        sum_log.info(f'    ---- Test: {report.nodeid}' )
        sum_log.info("    --------------------------------------\n")

这是带有yield语句的会话作用域夹具：

@pytest.fixture(scope="session")
def logger(testinfo):

    sum_log = dnet_generic.get_logger(initialize=True)

    ############################################################
    # Don't like to do this but I'm going to add a new key
    # to testinfo which defines the summary.log logger
    # Since dictionaries are mutable this should work fine....
    ############################################################
    testinfo.update({"sum_log" : sum_log })

    start_time = testinfo['start_time'].strftime('%a %b %d %H:%M:%S %Z %Y')
    script_name = sys.argv[0]
    script_args = sys.argv[1:] # all remaining arguments other than script name
    script_basename = os.path.basename(script_name)

    sum_log.info("\n\n----------------------------------------------------------")
    sum_log.info("----------------------------------------------------------")
    sum_log.info('-----Pytest Session Started' )
    sum_log.info('-----Start Time:: %s' % (start_time) )
    sum_log.info('-----Results for script_name %s' % (script_basename))
    sum_log.info('-----Script Arguments %s' % ' '.join(map(str,script_args)))
    sum_log.info("----------------------------------------------------------")
    sum_log.info("----------------------------------------------------------")

    yield sum_log

    now = datetime.datetime.now()
    end_time = now.strftime('%a %b %d %H:%M:%S %Z %Y')
    script_basename = os.path.basename(script_name)

    sum_log.info("+++++++++++++++++++++++++++++++++++++++++++++")
    sum_log.info("+++++++++++++++++++++++++++++++++++++++++++++")
    sum_log.info('-----Pytest Session Ended' )
    sum_log.info('-----End Time: %s' % (end_time) )
    sum_log.info("+++++++++++++++++++++++++++++++++++++++++++++")
    sum_log.info("+++++++++++++++++++++++++++++++++++++++++++++")

我只有拆解问题。如果我在一个模块中有5个独立的测试功能，则此钩子将被调用5次，并将适当的消息写到日志文件中，然后Session作用域的夹具最后将日志写到日志文件中。

这是当yield语句后另一个“作用域”夹具失败时日志文件的输出的样子（我需要在“ Pytest Session Ended”消息之前出现Teardown消息：

+++++++++++++++++++++++++++++++++++++++++++++
+++++++++++++++++++++++++++++++++++++++++++++
-----Pytest Session Ended
-----End Time: Wed Apr 08 02:48:31  2020
+++++++++++++++++++++++++++++++++++++++++++++
+++++++++++++++++++++++++++++++++++++++++++++

    --------------------------------------
    ---- Test Teardown Stage FAILED!
    ---- Test: lag/test_preconfig_setup.py::test_lag_load_balance[au22-bundle-28130-4-80-128-True-60-lag_setup_test.yml]
    --------------------------------------

将会话日志从夹具“记录器”传输到测试会话相关的钩子。
示例 - “pytest_sessionstart”和“pytest_sessionfinish”
(https://docs.pytest.org/en/stable/_modules/_pytest/hookspec.html#pytest_sessionfinish)
我的简单检查 -

@pytest.hookspec(firstresult=True)
def pytest_sessionstart(session):

    print("\n+++++++++++++++++++++++++++++++++++++++++++++")
    print('\n-----Pytest Session Started')
    print("\n+++++++++++++++++++++++++++++++++++++++++++++")


@pytest.hookspec(firstresult=True)
def pytest_sessionfinish(session, exitstatus):

    print("\n+++++++++++++++++++++++++++++++++++++++++++++")
    print('\n-----Pytest Session Ended')
    print("\n+++++++++++++++++++++++++++++++++++++++++++++")

使用您的“pytest_report_teststatus”，当夹具在产出后失败

pytest_report_teststatus挂钩在会话范围内的拆卸固定装置之后执行
