前言：

pytest可以规定那些要跑，那些不跑，跑特定的哪些？比如以下的这个例子：

#!/usr/bin/env/python
# -*-coding:utf-8-*-import pytest@pytest.mark.runtest
def test_run():
print("run")def test_not_run():
passdef test_not_run1():
passclass TestClass:
def test_method(self):
passif __name__ == "__main__":
pytest.main(["-s", "test_case.py", "-m=runtest"]) #代表只跑标识为runtest的case

运行结果：显示一个执行，3个没有被选择

只运行用runcase标记的测试，cmd运行的时候，加个-m 参数，指定参数值runcase

如果不想执行runcase标记的case的时候，只需要在配置里面添加一个not runcase，比如以下：

#!/usr/bin/env/python
# -*-coding:utf-8-*-import pytestdef test_run():
print("run")@pytest.mark.runtest
def test_not_run():
print("run")def test_not_run1():
print("run")class TestClass:
def test_method(self):
pass

运行结果：三个执行完，一个没有被选择

Process finished with exit code 0

cmd命令：pytest -v -m “not runtest”

-v 注定的函数节点id：

如果想指定运行某个.py模块下，类里面的一个用例，如：TestClass里面testmethod用例
每个test开头(或_test结尾)的用例，函数(或方法)的名称就是用例的节点id，指定节点id运行用-v 参数

$ pytest -v test_server.py::TestClass::test_method

当然也能选择运行整个class
