1 pytest学习笔记 - 1.1 运行pytest
1.1 运行pyest 在命令行执行pytest --help
usage: pytest [options] [file_or_dir] [file_or_dir] [...]
... ...1.1.1 pytest不携带参数 pytest不带参数时会扫描当前目录下的所有目录、子目录中符合测试用例标准的文件(test_*.py, *_test.py)并执行这些文件。
1.1.2 pytest携带文件名、目录、或者文件列表、目录列表
携带文件名执行指定文件名中的测试用例(函数名满足test_...)。携带目录名执行指定目录中的所有测试文件中的所有测试用例(文件名满足test_....py或..._test.py)。携带文件列表执行文件列表中所有文件中的所有测试用例。携带目录列表执行指定目录列表中的所有测试文件中的所有用例(会递归扫描所有子目录)。
