将unittest脚本改为pytest， unittest中的setUp()方法处理

  直接使用pytest运行unittest脚本时，pytest无法使用unittest下的setUp()，这也是pytest和unittest为数不多差异。有两种替换方法：
unittest源码示例：

from unittest import TestCase
from ApiT.feed.feed_video_parse import video_parse

class Test_video_parse(TestCase):
    def setUp(self, url_videos = ['https://v.ixigua.com/JhshhQo/','https://v.kuaishou.com/5WIabR', 'https://v.douyin.com/Jhs8bpj/',
                      'https://b23.tv/wGJ4hU']):
        # 西瓜、快手、抖音、bilibili视频类型校验
        self.url_videos = url_videos

    def test_video_parse(self, url_video = 'https://youtu.be/B6pRp8aCYXQ'):
        # 返回结构校验
        res = video_parse(url_video)

        # 返回的dict格式，即正常解析视频地址
        if isinstance(res, dict):
            assert res['data'].__contains__('id')
            assert res['data'].__contains__('thumb')
            assert res['data'].__contains__('source_site')
            assert res['data'].__contains__('source_url')
            assert res['data'].__contains__('video')
            assert res['data'].__contains__('parse')

            if url_video.__contains__('kuaishou') or url_video.__contains__('youtu'):
                pass
            else:
                assert res['data'].__contains__('time_length')
        else:
            print('error ! ')

    def test_video_parse_type(self):

        for url_video in  self.url_videos :
            self.test_video_parse(url_video)

1. 将setUp()变更为pytest可以识别的方法：

   def setup_method(self, method, url_videos = ['https://v.ixigua.com/JhshhQo/','https://v.kuaishou.com/5WIabR', 'https://v.douyin.com/Jhs8bpj/',
                         'https://b23.tv/wGJ4hU']):
           # 西瓜、快手、抖音、bilibili视频类型校验
           self.url_videos = url_videos
   

2. 使用pytest.fixture注解：
   1. 将setUp()方法重名为非特殊方法名，比如：one
   2. 给one()方法添加@pytest.fixture()注解
   3. 在调用到one()方法的地方添加`@pytest.mark.usefixtures(‘one’)，指明该方法会调用one()

      from unittest import TestCase
      
      import allure
      import pytest
      
      from ApiT.feed.feed_video_parse import video_parse
      
      @allure.feature('视频解析接口测试')
      class Test_video_parse():
          @pytest.fixture()
          def one(self,  url_videos = ['https://v.ixigua.com/JhshhQo/','https://v.kuaishou.com/5WIabR', 'https://v.douyin.com/Jhs8bpj/',
                            'https://b23.tv/wGJ4hU']):
              # 西瓜、快手、抖音、bilibili视频类型校验
              self.url_videos = url_videos
      
          def test_video_parse(self, url_video = 'https://youtu.be/B6pRp8aCYXQ'):
              # 返回结构校验
              res = video_parse(url_video)
      
              # 返回的dict格式，即正常解析视频地址
              if isinstance(res, dict):
                  assert res['data'].__contains__('id')
                  assert res['data'].__contains__('thumb')
                  assert res['data'].__contains__('source_site')
                  assert res['data'].__contains__('source_url')
                  assert res['data'].__contains__('video')
                  assert res['data'].__contains__('parse')
      
                  if url_video.__contains__('kuaishou') or url_video.__contains__('youtu'):
                      pass
                  else:
                      assert res['data'].__contains__('time_length')
              else:
                  print('error ! ')
          @pytest.mark.usefixtures('one')
          def test_video_parse_type(self):
      
              for url_video in  self.url_videos :
                  self.test_video_parse(url_video)
