Pytest

Init

Run

更改配置pytest.ini与项目同级

# content of pytest.ini
# Example 1: have pytest look for "check" instead of "test"
[pytest]
;更改目录递归
norecursedirs = .svn _build tmp*;更改命名约定
python_files = check_*.py
python_classes = Check
python_functions = *_check
;可以通过在模式之间添加空格来检查多个 glob 模式
;python_files = test_*.py example_*.py;将命令行参数解释
;addopts = --tb=short
;addopts = --pyargs
;export PYTEST_ADDOPTS="-v"
addopts = -vv --html-report=report.html

引进@pytest.mark.parametrize中ids导致编码乱码

def pytest_collection_modifyitems(items):for item in items:item.name = item.name.encode('utf-8').decode('unicode-escape')item._nodeid = item._nodeid.encode('utf-8').decode('unicode-escape')

定义自己对失败断言的解释 pytest_assertrepr_compare(config, op, left, right)
- config (Config) – The pytest config object.
- op (str) – The operator, e.g. “==”, “!=”, “not in”.
- left (object) – The left operand.
- right (object) – The right operand.

# content of conftest.py
from test_foocompare import Foodef pytest_assertrepr_compare(op, left, right):if isinstance(left, Foo) and isinstance(right, Foo) and op == "==":return ["Comparing Foo instances:",f"   vals: {left.val} != {right.val}",]

# content of test_foocompare.py
class Foo:def __init__(self, val):self.val = valdef __eq__(self, other):return self.val == other.valdef test_compare():f1 = Foo(1)f2 = Foo(2)assert f1 == f2

output

3. 根据命令行选项将不同的值传递给测试函数

# content of conftest.py
import pytestdef pytest_addoption(parser):parser.addoption("--cmdopt", action="store", default="type1", help="my option: type1 or type2")@pytest.fixture
def cmdopt(request):return request.config.getoption("--cmdopt")

# content of test_sample.py
def test_answer(cmdopt):if cmdopt == "type1":print("first")elif cmdopt == "type2":print("second")assert 0  # to see what was printed

output

如果需要更详细信息

# content of conftest.py
import pytestdef type_checker(value):msg = "cmdopt must specify a numeric type as typeNNN"if not value.startswith("type"):raise pytest.UsageError(msg)try:int(value[4:])except ValueError:raise pytest.UsageError(msg)return valuedef pytest_addoption(parser):parser.addoption("--cmdopt",action="store",default="type1",help="my option: type1 or type2",type=type_checker,)

output

$ pytest -q --cmdopt=type3
ERROR: usage: pytest [options] [file_or_dir] [file_or_dir] [...]
pytest: error: argument --cmdopt: invalid choice: 'type3' (choose from 'type1', 'type2')

Report

1. 向测试报告标题添加信息

1.1

# content of conftest.pydef pytest_report_header(config):return "project deps: mylib-1.1"

output

$ pytest
=========================== test session starts ============================
platform linux -- Python 3.x.y, pytest-8.x.y, pluggy-1.x.y
project deps: mylib-1.1
rootdir: /home/sweet/project
collected 0 items========================== no tests ran in 0.12s ===========================

1.2 返回字符串列表，这些字符串将被视为多行信息

# content of conftest.pydef pytest_report_header(config):if config.get_verbosity() > 0:return ["info1: did you know that ...", "did you?"]

output 仅在使用“-v”运行时才会添加信息

$ pytest -v
=========================== test session starts ============================
platform linux -- Python 3.x.y, pytest-8.x.y, pluggy-1.x.y -- $PYTHON_PREFIX/bin/python
cachedir: .pytest_cache
info1: did you know that ...
did you?
rootdir: /home/sweet/project
collecting ... collected 0 items========================== no tests ran in 0.12s ===========================

2. 分析测试持续时间 `pytest --durations=3`

# content of test_some_are_slow.py
import timedef test_funcfast():time.sleep(0.1)def test_funcslow1():time.sleep(0.2)def test_funcslow2():time.sleep(0.3)

output

$ pytest --durations=3
=========================== test session starts ============================

0.10s call     test_some_are_slow.py::test_funcfast
============================ 3 passed in 0.12s =============================

3. 增量测试 - 测试步骤

如果前置步骤其中一个步骤失败，则后续步骤将预期失败。

# content of conftest.pyfrom typing import Dict, Tupleimport pytest# store history of failures per test class name and per index in parametrize (if parametrize used)
_test_failed_incremental: Dict[str, Dict[Tuple[int, ...], str]] = {}def pytest_runtest_makereport(item, call):if "incremental" in item.keywords:# incremental marker is usedif call.excinfo is not None:# the test has failed# retrieve the class name of the testcls_name = str(item.cls)# retrieve the index of the test (if parametrize is used in combination with incremental)parametrize_index = (tuple(item.callspec.indices.values())if hasattr(item, "callspec")else ())# retrieve the name of the test functiontest_name = item.originalname or item.name# store in _test_failed_incremental the original name of the failed test_test_failed_incremental.setdefault(cls_name, {}).setdefault(parametrize_index, test_name)def pytest_runtest_setup(item):if "incremental" in item.keywords:# retrieve the class name of the testcls_name = str(item.cls)# check if a previous test has failed for this classif cls_name in _test_failed_incremental:# retrieve the index of the test (if parametrize is used in combination with incremental)parametrize_index = (tuple(item.callspec.indices.values())if hasattr(item, "callspec")else ())# retrieve the name of the first test function to fail for this class name and indextest_name = _test_failed_incremental[cls_name].get(parametrize_index, None)# if name found, test has failed for the combination of class name & test nameif test_name is not None:pytest.xfail(f"previous test failed ({test_name})")

# content of test_step.pyimport pytest@pytest.mark.incremental
class TestUserHandling:def test_login(self):passdef test_modification(self):assert 0def test_deletion(self):passdef test_normal():pass

output

–junitxml={report}.xml

https://docs.pytest.org/en/stable/reference/reference.html
pytest v6.0+ 默认 xunit2 不支持 testcase添加属性
建议设置

pytest.ini中配置junit_family=xunit1
pytest -o junit_family=xunit1

<?xml version="1.0" encoding="utf-8"?>
<testsuites><testsuite name="pytest" errors="0" failures="0" skipped="0" tests="2" time="0.113"timestamp="2025-03-10T14:53:08.040765+08:00" hostname="Ding-Perlis-MP1Y70F1"><testcase classname="set_classname" name="set_name" file="test_case.py" line="49" time="0.006"/><testcase classname="set_classname" name="set_name" file="test_case.py" line="49" time="0.001"/></testsuite>
</testsuites>

1. testsuite

1.1 在测试套件级别添加属性节点 record_testsuite_property

支持xunit2

import pytest@pytest.fixture(scope="session", autouse=True)
def log_global_env_facts(record_testsuite_property):record_testsuite_property("ARCH", "PPC")record_testsuite_property("STORAGE_TYPE", "CEPH")class TestMe:def test_foo(self):assert True

output


<testsuite errors="0" failures="0" name="pytest" skipped="0" tests="1" time="0.006"><properties><property name="ARCH" value="PPC"/><property name="STORAGE_TYPE" value="CEPH"/></properties><testcase classname="test_me.TestMe" file="test_me.py" line="16" name="test_foo" time="0.000243663787842"/>
</testsuite>

2. testcase

2.1 记录测试的其他信息 record_property

请注意，使用此功能将中断对最新JUnitXML架构的架构验证。当与某些CI服务器一起使用时，这可能是一个问题

方法一 test_case.py

def test_function(record_property):record_property("example_key", 1)assert True

方法二 contest.py

# content of conftest.pydef pytest_collection_modifyitems(session, config, items):for item in items:for marker in item.iter_markers(name="test_id"):test_id = marker.args[0]item.user_properties.append(("test_id", test_id))# content of test_function.py
import pytest@pytest.mark.test_id(1501)
def test_function():assert True

output


<templt><testcase classname="test_function" file="test_function.py" line="0" name="test_function" time="0.0009"><properties><property name="example_key" value="1"/></properties></testcase><testcase classname="test_function" file="test_function.py" line="0" name="test_function" time="0.0009"><properties><property name="test_id" value="1501"/></properties></testcase>
</templt>

2.2 向testcase元素添加额外的xml属性 record_xml_attribute

record_xml_attribute 是一个实验性的特性，它的接口在未来的版本中可能会被更强大和通用的东西所取代。然而，功能本身将保持不变
请注意，使用此功能将中断对最新JUnitXML架构的架构验证。当与某些CI服务器一起使用时，这可能是一个问题

方法一 test_case.py

import pytest@pytest.mark.parametrize("case", ["case1", "case2"])
def test_case(case, record_xml_attribute):record_xml_attribute('classname', 'set_classname')  # 重写 valuerecord_xml_attribute('name', 'set_name')  # 重写 valuerecord_xml_attribute('index', '123')  # 新增 key, valueprint("hello world")assert True

方法二 contest.py

# edit to contest.py
import pytest@pytest.fixture(autouse=True)
def record_index(record_xml_attribute):record_xml_attribute('index', '123')  # 新增 key, value

output

<?xml version="1.0" encoding="utf-8"?>
<testsuites><testsuite name="pytest" errors="0" failures="0" skipped="0" tests="2" time="0.113"timestamp="2025-03-10T14:53:08.040765+08:00" hostname="Ding-Perlis-MP1Y70F1"><testcase classname="set_classname" name="set_name" file="test_case.py" line="49" index="123" time="0.006"><system-out>hello world</system-out></testcase><testcase classname="set_classname" name="set_name" file="test_case.py" line="49" index="123" time="0.001"/></testsuite>
</testsuites>
