pytest文档40-pytest.ini配置用例查找规则(面试题)

前言

面试题:pytest如何执行不是test开头的用例？如执行 xxx_*.py这种文件的用例。
pytest.ini 配置文件可以修改用例的匹配规则。

pytest命令行参数

cmd打开输入pytest -h 查看命令行参数找到 [pytest] ini-options

• pythonfiles (args)      匹配 python 用例文件， 如test.py、  _test.py

• python_classes (args)    匹配 class 类名称   如Test*.py

• pythonfunctions (args)  匹配函数和class里面方法  如test*

修改匹配规则

pytest 默认查找用例匹配规则

• 测试文件以test_开头（以_test结尾也可以）

• 测试类以Test开头，并且不能带有 init 方法

• 测试函数以test_开头

如果我们想匹配以 xxx_*.py的文件，pytest.ini 文件放到项目的根目录。
在 pytest.ini 文件添加一项 python_files 即可

[pytest]

python_files = xxx_*.py

使用案例

写一个 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")

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

def test_2():
print("world")
