0三、pytest查找測試策略

默認狀況下,pytest會遞歸查找當前目錄下全部以test開始或結尾的Python腳本,並執行文件內的全部以test開始或結束的函數和方法.

etc
├── robocop.toml
├── test_data.py
└── test_demo.py

---

1、執行某文件夾下全部test打頭的py文件中test打頭的函數(測試用例)

╰ pytest -v etc
=================================================== test session starts ====================================================
platform darwin -- Python 3.7.4, pytest-4.4.0, py-1.8.0, pluggy-0.13.0 -- /Users/zhouwanghua/Code/Leyan/python/robocop/bin/python

2、執行某個py文件下全部的測試用例:

╰ pytest -v etc/test_demo.py            
=================================================== test session starts ====================================================
platform darwin -- Python 3.7.4, pytest-4.4.0, py-1.8.0, pluggy-0.13.0 -- /Users/zhouwanghua/Code/Leyan/python/robocop/bin/python

collected 2 items                                                                                                          

etc/test_demo.py::test_demo PASSED                                                                                   [ 50%]
etc/test_demo.py::test_demo2 PASSED   
================================================= 2 passed in 0.01 seconds =================================================

---

3、測試某個文件中的某1個測試用例

╰ pytest -v etc/test_demo.py::test_demo2
=================================================== test session starts ====================================================
platform darwin -- Python 3.7.4, pytest-4.4.0, py-1.8.0, pluggy-0.13.0 -- /Users/zhouwanghua/Code/Leyan/python/robocop/bin/python

etc/test_demo.py::test_demo2 PASSED                                                                                  [100%]
