pytest文檔40-pytest.ini配置用例查找規則(面試題)

前言

面試題:pytest如何執行不是test開頭的用例？如執行 xxx_*.py這種文件的用例。
pytest.ini 配置文件可以修改用例的匹配規則。

pytest命令行參數

cmd打開輸入pytest -h 查看命令行參數找到 [pytest] ini-options

• python_files (args) 匹配 python 用例文件， 如test_*.py、 *_test.py
• python_classes (args) 匹配 class 類名稱 如Test*.py
• python_functions (args) 匹配函數和class里面方法 如test_*

  rsyncignore (pathlist)   list of (relative) glob-style paths to be ignored for
  looponfailroots (pathlist) directories to check for changes

修改匹配規則

pytest 默認查找用例匹配規則

• 測試文件以test_開頭（以_test結尾也可以）
• 測試類以Test開頭，並且不能帶有 init 方法
• 測試函數以test_開頭

如果我們想匹配以 xxx_*.py的文件，pytest.ini 文件放到項目的根目錄。
在 pytest.ini 文件添加一項 python_files 即可

[pytest]

python_files =  xxx_*.py

使用案例

寫一個 xxx_yoyo.py 的文件用例

#  xxx_yoyo.py
# 作者：上海-悠悠 QQ交流群：779429633
def test_1():
    print("hello")


def test_2():
    print("world")

cmd 輸入 pytest 執行，就可以匹配到了

D:\soft\demo>pytest
============================= test session starts =============================

xxx_yoyo.py hello

匹配測試用例類和方法相關配置參考如下

[pytest]

python_files =  xxx_*.py *_xxx.py
python_classes = Test*
python_functions = test_*

多個匹配規則中間用空格隔開,其它配置參考這篇https://www.cnblogs.com/yoyoketang/p/9550648.html
