1、fixture之 yield 实现 teardown

 

  a、带有 yield 的函数在 Python 中被称之为 generator(生成器) ,可以暂时简单的理解为函数的return , 后面可以加返回值  yield  login_status, code 。

     项目层级如下:

     018、fixture之 yield 实现 teardown_IT

 

  conftest.py 代码如下:

import pytest


@pytest.fixture(scope='class')
def open_browser():
    print('\n打开浏览器')
    result = '打开浏览器成功'

    # yield 相当于return ,可返回值; 此处返回result的值 ;
    yield result

    print('\n关闭浏览器')

  test_ff.py 代码如下:

class TestWeb():

    # 调用open_browser接受返回值
    def test_open_web(self, open_browser):
        result = open_browser
        print(result)
        print('\n打开网站')

    def test_close_web(self):
        print('\n关闭网站')

  执行结果如下:
