Pytest 测试框架结构(setup/teardown)
测试装置介绍
类型 | 规则 |
---|---|
setup_module/teardown_module | 全局模块级 |
setup_class/teardown_class | 类级,只在类中前后运行一次 |
setup_function/teardown_function | 函数级,在类外 |
setup_method/teardown_method | 方法级,类中的每个方法执行前后 |
setup/teardown | 在类中,运行在调用方法的前后(重点) |
'''
模块级(setup_module/teardown_module)模块始末,全局的(优先最高)
函数级(setup_function/teardown_function)只对函数用例生效(不在类中)
类级(setup_class/teardown_class)只在类中前后运行一次(在类中)
方法级(setup_method/teardown_methond)开始于方法始末(在类中)
类里面的(setup/teardown)运行在调用方法的前后
