通过标记表达式执行
pytest -m demo
这条命令会执行被装饰器@pytest.mark.demo装饰的所有测试用例

生成html报告:
pytest -m demo --html=Report/report.html

生成xml报告:
pytest -m demo --junitxml=Report/report.xml

运行指定模块:
pytest -m demo --html=Report/report.html TestCases/test_pytest.py

运行指定测试目录
pytest -m demo --html=Report/report.html TestCases/

通过节点id来运行:
pytest TestCases/test_pytest.py::TestDemo::test_demo01

通过关键字表达式过滤执行
pytest -k "MyClass and not method"
这条命令会匹配文件名、类名、方法名匹配表达式的用例
