1 学习起源

https://docs.pytest.org/en/latest/index.html

2 依赖的环境

环境版本
python>=3.6
平台反对linux、windows

3 本文学习环境

  • Python：3.7.0
  • 操作系统：windows10，64位

  • Pycharm：2020.2

4 pytest装置

  • 关上cmd命令行，间接输出：
pip install -U pytest
  • 装置如下：

5 查看pytest版本

  • 应用pip show命令
pip show pytest
(venv) F:\pytest_study>pip show pytestName: pytestVersion: 6.2.4Summary: pytest: simple powerful testing with PythonHome-page: https://docs.pytest.org/en/latest/Author: Holger Krekel, Bruno Oliveira, Ronny Pfannschmidt, Floris Bruynooghe, Brianna Laugher, Florian Bruhin and othersAuthor-email:License: MITLocation: d:\python37\lib\site-packagesRequires: pluggy, importlib-metadata, attrs, iniconfig, toml, py, packaging, atomicwrites, coloramaRequired-by: pytest-xdist, pytest-rerunfailures, pytest-ordering, pytest-metadata, pytest-html, pytest-forked, pytest-cov, allure-pytest
  • 应用--version命令，如果报错提醒如下：
    plugin = ep.load()  File "d:\python37\lib\site-packages\importlib_metadata\__init__.py", line 105, in load    module = import_module(match.group('module'))  File "d:\python37\lib\importlib\__init__.py", line 127, in import_module    return _bootstrap._gcd_import(name[level:], package, level)  File "<frozen importlib._bootstrap>", line 1006, in _gcd_import  File "<frozen importlib._bootstrap>", line 983, in _find_and_load  File "<frozen importlib._bootstrap>", line 967, in _find_and_load_unlocked  File "<frozen importlib._bootstrap>", line 677, in _load_unlocked  File "d:\python37\lib\site-packages\_pytest\assertion\rewrite.py", line 170, in exec_module    exec(co, module.__dict__)  File "d:\python37\lib\site-packages\pytest_rerunfailures.py", line 8, in <module>    from _pytest.resultlog import ResultLogModuleNotFoundError: No module named '_pytest.resultlog'
  • 是因为之前装置过pytest-rerunfailures是用例失败重跑，pytest-rerunfailures不能与pytest 6.1.0以上的版本一起应用，所以卸载pytest-rerunfailures后应用pytest-reportlog来代替即可；
# 卸载pytest-rerunfailurespip uninstall pytest-rerunfailures# 装置pytest-reportlogpip install pytest-reportlog
  • 再次查看pytest版本OK了
(venv) F:\pytest_study>pytest -Vpytest 6.2.4
