浅谈Pytest中的marker

没有注册marker

我们写一个简单的测试

# test_demo.py

import pytest

@pytest.mark.login

def test_demo():

    assert True

你运行的话会有如下提示

test_demo.py:4: PytestUnknownMarkWarning: Unknown pytest.mark.login - is this a typo?  You can register custom marks to avoid this warning - for details, see https://docs.pytest.org/en/stable/how-to/mark.html

    @pytest.mark.login

-- Docs: https://docs.pytest.org/en/stable/how-to/capture-warnings.html

上面两个文档值得你的仔细阅读

注册marker方式一：pytest.ini

新建一个文件pytest.ini(在哪里创建?你应该要知道，跟你的项目结构有关)，写入如下内容

[pytest]

markers:

    login: login test demo

再次运行就不会有PytestUnknownMarkWarning

注册marker方式二：pytest_configure

创建一个conftest.py

def pytest_configure(config):

    config.addinivalue_line(

        "markers", "login: login test demo"

    )

效果是一样的

带marker运行

通过命令行参数-m即可

比如现在有这个case

import pytest

@pytest.mark.login

def test_demo1():

    assert True

@pytest.mark.logout

def test_demo2():

    assert True

contest.py

def pytest_configure(config):

    config.addinivalue_line("markers", "login: login test demo",)

    config.addinivalue_line("markers", "logout: logout test demo")# 注意一个marker要写一个addinivalue_line

运行的时候带上-m login即可选择登录用例进行测试

而-m的语法还比较复杂，可以参考-k的

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 don't

  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'.

关于marker的其他

查询markers

pytest --markers

# 能查到当前注册的markers

命令行参数--strict-markers

pytest.main(['-sv','--strict-markers',__file__])   # 强制markers必须要注册

或者放pytest.ini中
```
[pytest]

addopts = --strict-markers
```

会产生如下信息

=================================== ERRORS ====================================

________________________ ERROR collecting test_demo.py ________________________

'login' not found in `markers` configuration option

=========================== short test summary info ===========================

ERROR test_demo.py

!!!!!!!!!!!!!!!!!!! Interrupted: 1 error during collection !!!!!!!!!!!!!!!!!!!!

============================== 1 error in 0.08s ===============================

marker是pytest中pick用例的多种方式之一(-m)，其他pick用例的方式比如-k，--allure的几个

  --allure-severities=SEVERITIES_SET

  --allure-epics=EPICS_SET

  --allure-features=FEATURES_SET

  --allure-stories=STORIES_SET

  --allure-ids=IDS_SET  Comma-separated list of IDs.

  --allure-link-pattern=LINK_TYPE:LINK_PATTERN
