【问题描述】:
我想获取有关在测试call 阶段引发的异常的信息,并将它们添加到使用pytest-html 插件创建的报告中。所以我为pytest_runtest_makereport创建了hookwrapper:
@hookimpl(hookwrapper=True)
def pytest_runtest_makereport(call):
outcome = yield
result = outcome.get_result()
errors = getattr(result, "errors", [])
if result.when == "call":
if result.failed:
if error := call.excinfo:
errors.append(error.typename)
result.errors = errors
else:
logger.info("PASSED")
要将此信息添加到测试报告中,我正在使用:
def pytest_html_results_table_html(report, data):
del data[:]
if errors := getattr(report, "errors", []):
data.append(html.div(", ".join(errors), class_="failed log"))
不幸的是,pytest_html_results_table_html 报告实例中没有错误字段。如果我将result.errors = errors 添加到拆卸阶段,字段会出现在报告对象中,但它有空列表。
我知道有一个extra 字段,但pytest-html 将它直接添加到报告中。我想在添加这些值之前对它们做一些事情。
那么我在这里缺少什么?如何将此值从pytest_runtest_makereport 传递给pytest_html_results_table_html?
我正在使用的示例测试类:
from logging import getLogger
from pytest import fixture
logger = getLogger()
class TestVariousOutputs:
@fixture()
def setup(self):
logger.info("Run setup")
raise RuntimeError("Error raised during setup")
@fixture()
def teardown(self):
logger.info("Run setup")
yield
logger.info("Run teardown")
raise RuntimeError("Error raised during teardown")
def test_pass(self):
logger.info("Run test")
assert True
def test_fail(self):
logger.info("Run test")
assert False, "Assert False"
def test_raise_error(self):
logger.info("Run test")
raise RuntimeError("Error raised during test run")
def test_setup_raise_error(self, setup):
logger.info("Run test")
assert True
def test_teardown_raise_error(self, teardown):
logger.info("Run test")
assert True
def test_teardown_raise_error_and_test_fails(self, teardown):
logger.info("Run test")
assert False, "Assert False but teardown should also fail"
