pytest 13 使用自定义标记mark

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():
    pass

def test_not_run1():
    pass

class TestClass:
    def test_method(self):
        pass

if __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 pytest

def 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

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

$ pytest -v test_server.py::TestClass

也能选择多个节点运行，多个节点中间空格隔开

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

-k配皮用例名称

可以使用-k命令行选项指定在匹配用例名称的表达式

pytest -v -k not_run

也可以运行所有的测试，根据用例名称排除掉某些用例：

pytest  -k “not not_run” -v

也可以同时选择匹配 “run” 和“not not_run”

pytest  -k “run and not not_run” -v
