Pytest - 重命名fixture函数名称（name）
-
fixture 设置参数
name=value后，可以重命名fixture函数名称，运行时传入重命名后的fixture函数名即可。 -
使用重命名的fixture函数，可以使用装饰器：
@pytest.mark.usefixtures()；
import pytest
# 编写fixture
@pytest.fixture(name="open_browser_and_login")
def login():
print("\\nFixtrue：输入账号，密码先登录")
# 此处需传入重命名后的fixture函数名
@pytest.mark.usefixtures("open_browser_and_login")
def test_s1():
print("\\n用例test_s1：装饰器调用重命名后的login函数")
def test_s2(open_browser_and_login):
print("\\n用例test_s2：直接调用login函数")
if __name__ == \'__main__\':
pytest.main([\'-q\', \'test_py.py\'])
pytest学习和使用18-pytest.ini配置文件如何使用？
(18-pytest.ini配置文件如何使用？)
1 配置文件的作用
- 改变
pytest的运行方式； pytest.ini是一个固定的文件；pytest.ini用来读取配置信息。
2 文件格式
# 文件名为：pytest.ini
[pytest]
addopts =
xfail_strict =
3 查看pytest.ini的选项
- 使用命令：
pytest --help
- 如下：
C:\\Users\\Administrator>pytest --help
usage: pytest [options] [file_or_dir] [file_or_dir] [...]
positional arguments:
file_or_dir
general:
-k EXPRESSION only run tests which match the given substring expression. An expression is a python evaluatable
expression where all names are substring-matched against test names and their parent classes.
Example: -k test_method or test_other matches all test functions and classes whose name
contains test_method or test_other, while -k not test_method matches those that dont
contain test_method in their names. -k not test_method and not test_other will eliminate the
matches. Additionally keywords are matched to classes and functions containing extra names in
their extra_keyword_matches set, as well as functions which have names assigned directly to
them. The matching is case-insensitive.
-m MARKEXPR only run tests matching given mark expression.
For example: -m mark1 and not mark2.
--markers show markers (builtin, plugin and per-project ones).
-x, --exitfirst exit instantly on first error or failed test.
--fixtures, --funcargs
show available fixtures, sorted by plugin appearance (fixtures with leading _ are only shown
with -v)
--fixtures-per-test show fixtures per test
--pdb start the interactive Python debugger on errors or KeyboardInterrupt.
--pdbcls=modulename:classname
start a custom interactive Python debugger on errors. For example:
--pdbcls=IPython.terminal.debugger:TerminalPdb
--trace Immediately break when running each test.
--capture=method per-test capturing method: one of fd|sys|no|tee-sys.
-s shortcut for --capture=no.
--runxfail report the results of xfail tests as if they were not marked
--lf, --last-failed rerun only the tests that failed at the last run (or all if none failed)
--ff, --failed-first run all tests, but run the last failures first.
This may re-order tests and thus lead to repeated fixture setup/teardown.
--nf, --new-first run tests from new files first, then the rest of the tests sorted by file mtime
--cache-show=[CACHESHOW]
show cache contents, dont perform collection or tests. Optional argument: glob (default: *).
--cache-clear remove all cache contents at start of test run.
--lfnf=all,none, --last-failed-no-failures=all,none
which tests to run with no previously (known) failures.
--sw, --stepwise exit on test failure and continue from last failing test next time
--sw-skip, --stepwise-skip
ignore the first failing test but stop on the next failing test

(X)passed, (p)assed, (P)assed with output, (a)ll except passed (p/P), or (A)ll. (w)arnings are
enabled by default (see --disable-warnings), N can be used to reset the list. (default: fE).

def test_case_02(self):
print("case_02")
if __name__ == __main__:
pytest.main(["-v", "test_ini.py", "-m=case"])
- 标签多容易出错，可以写入到
pytest.ini：
# pytest.ini
[pytest]
markers =
name: run the name
old: run the old
case: run the test_case
- 标记后可使用
pytest --markers查看：
(venv) F:\\pytest_study\\test_case\\test_i>pytest --markers
@pytest.mark.name: run the name
@pytest.mark.old: run the old
@pytest.mark.case: run the test_case
@pytest.mark.forked: Always fork for this test.
@pytest.mark.flaky(reruns=1, reruns_delay=0): mark test to re-run up to reruns times. Add a delay of rerun
s_delay seconds between re-runs.
@pytest.mark.repeat(n): run the given test function `n` times.
@pytest.mark.run: specify ordering information for when tests should run in relation to one another. Provided
by pytest-ordering. See also: http://pytest-ordering.readthedocs.org/
@pytest.mark.no_cover: disable coverage for this test.
@pytest.mark.allure_label: allure label marker
@pytest.mark.allure_link: allure link marker
@pytest.mark.allure_display_name: allure test name marker
@pytest.mark.allure_description: allure description
@pytest.mark.allure_description_html: allure description html
@pytest.mark.filterwarnings(warning): add a warning filter to the given test. see https://docs.pytest.org/en/
stable/warnings.html#pytest-mark-filterwarnings
@pytest.mark.skip(reason=None): skip the given test function with an optional reason. Example: skip(reason="n
o way of currently testing this") skips the test.
@pytest.mark.skipif(condition, ..., *, reason=...): skip the given test function if any of the conditions eva
luate to True. Example: skipif(sys.platform == win32) skips the test if we are on the win32 platform. See h
ttps://docs.pytest.org/en/stable/reference.html#pytest-mark-skipif
@pytest.mark.xfail(condition, ..., *, reason=..., run=True, raises=None, strict=xfail_strict): mark the test
function as an expected failure if any of the conditions evaluate to True. Optionally specify a reason for be
tter reporting and run=False if you dont even want to execute the test function. If only specific exception(
s) are expected, you can list them in raises, and if the test fails in other ways, it will be reported as a t
rue failure. See https://docs.pytest.org/en/stable/reference.html#pytest-mark-xfail
@pytest.mark.parametrize(argnames, argvalues): call a test function multiple times passing in different argum
ents in turn. argvalues generally needs to be a list of values if argnames specifies only one name or a list
of tuples of values if argnames specifies multiple names. Example: @parametrize(arg1, [1,2]) would lead to
two calls of the decorated test function, one with arg1=1 and another with arg1=2.see https://docs.pytest.org
/en/stable/parametrize.html for more info and examples.
@pytest.mark.usefixtures(fixturename1, fixturename2, ...): mark tests as needing all of the specified fixture
s. see https://docs.pytest.org/en/stable/fixture.html#usefixtures
@pytest.mark.tryfirst: mark a hook implementation function such that the plugin machinery will try to call it
first/as early as possible.
@pytest.mark.trylast: mark a hook implementation function such that the plugin machinery will try to call it
last/as late as possible.
5.2 xfail_strict
- 设置
xfail_strict = True可以让那些标记为@pytest.mark.xfail但实际通过显示XPASS的测试用例被报告标记为失败； - pytest.ini的写法：
[pytest]
markers =
name: run the name
old: run the old
case: run the test_case
xfail_strict = True
- 代码为：
# -*- coding:utf-8 -*-
# 作者：虫无涯
# 日期：2023/3/15
# 文件名称：test_ini01.py
# 作用：pytest.ini的使用
import pytest
@pytest.mark.name
def test_name():
print("name is xiaoming")
@pytest.mark.old
def test_old():
print("old is 20")
@pytest.mark.xfail()
def test_weight():
a = 30
b = 60
assert a != b
@pytest.mark.case
class TestCase:
def test_case_01(self):
print("case_01")
def test_case_02(self):
print("case_02")
if __name__ == __main__:
pytest.main(["-v", "test_ini01.py", "-m=case"])
- 结果如下，可以看到测试结果为失败：
test_ini01.py::test_name PASSED [ 20%]name is xiaoming
test_ini01.py::test_old PASSED [ 40%]old is 20
test_ini01.py::test_weight FAILED [ 60%]

========================= 1 failed, 4 passed in 0.05s =========================
5.3 addopts
addopts参数可以更改默认命令行选项；- 比如测试完生成报告，失败重跑3次，一共运行2次，通过分布式去测试：
addopts = -v --reruns=2 --count=2 --html=reports.html --self-contained-html -n=auto
- 把以上命令加入
pytest.ini，就不用在命令行重复去写这些参数：
[pytest]
markers =
name: run the name
old: run the old
case: run the test_case
xfail_strict = True
addopts = -v --reruns=2 --count=2 --html=reports.html --self-contained-html -n=auto
- 运行结果：

addopts常用参数：
| 参数 | 说明 |
|---|---|
-s |
表示输出调试信息，用于显示测试函数中print()打印的信息 |
-v |
未加前只打印模块名，加v后打印类名、模块名、方法名，显示更详细的信息 |
-q |
表示只显示整体测试结果 |
-vs |
这两个参数可以一起使用 |
-n |
支持多线程或者分布式运行测试用例（前提需安装pytest-xdist插件） |
-html |
生成html的测试报告（前提需安装pytest-html插件） 如：pytest -vs --html ./reports/result.html |
5.4 log_cli
- 控制台实时输出日志；
log_cli=True或False（默认）；log_cli=True：

- 加了
log_cli=True之后，可以清晰看到哪个package、module下的用例执行情况。
5.5 norecursedirs
- pytest 收集测试用例时，会递归遍历所有子目录；
- 如果有些目录不需要执行，可使用
norecursedirs参数简化pytest的搜索工作； - 方法如下，多个路径用空格隔开：
norecursedirs = .* build dist CVS _darcs arch *.egg
- 比如：
[pytest]
markers =
name: run the name
old: run the old
case: run the test_case
xfail_strict = True
# addopts = -v --reruns=2 --count=2 --html=reports.html --self-contained-html -n=auto
log_cli = False
norecursedirs = .* build dist CVS _darcs arch *.egg report test_case log
- 也可以使用
norecursedirs修改pytest的默认用例收集规则； - 其中默认用例收集规则为：
文件名以 test_*.py 文件和 *_test.py
以test_ 开头的函数
以Test 开头的类，不能包含 __init__ 方法
以test_ 开头的类里面的方法
- 比如修改为：
[pytest]
python_files = test* test_* *_test
python_classes = Test* test*
python_functions = test_* test*

[pytest]
markers =
name: run the name
old: run the old
case: run the test_case
xfail_strict = True
addopts = -v --reruns=2 --count=2 --html=reports.html --self-contained-html -n=auto
log_cli = False
norecursedirs = .* build dist CVS _darcs arch *.egg report test_case log
python_files = test* test_* *_test
python_classes = Test* test*
python_functions = test_* test*
