readME文件

总结:
1.模块级别最大,因为不管是函数式测试用例,还是类方式的测试用例,都在一个模块中
2.函数级别仅仅是针对,函数式测试用例生效(setup_function()不能再类方式中使用,类方式中要使用setup_method())
3.类级别和方法级别,是针对于类方式编写的测试用例生效
4.setup和teardown是可以替换函数级别和方法级别的前置后置


1.运行单个用例
pytest .\码同学\pytest_study\test_by_class.py::TestLogin::test_login_userisnull
2.运行整个类下 的所有用例
pytest -sv .\码同学\pytest_study\test_by_class.py
3.右键执行所有用例:光标放在所有第一个方法顶部

4.右键执行某一个用例:贯标放在对应的函数上

总结:
requests库的请求方法参数众多,划分如下:

global全局参数使用:不通的函数中如果想使用的话就用global


查询参数就用params=params
表单参数就用data=data
json参数就用json=json
文件参数就用files=files
请求头信息headers就用headers=headers
