[3. 用例并行执行 pytest-parallel](#3. 用例并行执行 pytest-parallel)

1. pytest-html

管理员打开 Anaconda Prompt 输入： pip install pytest-html

查询是否安装成功：

1.1 PermissionError: [Errno 13] Permission denied: 'D:\\software\\python3\\anconda3\\Lib\\site-packages\\pytest_html\\pycache\\tmp_ttoasov'

1.检查对应路径下的文件是否存在，且被占用。如果文件不存在，就找到对应文件即可；如果文件存在，被占用，将占用程序暂时关闭。

2.修改cmd的权限，以管理员身份运行。

3.检查是否是打开了文件夹。

hhhhhhh
Traceback (most recent call last):
  File "D:\software\python3\anconda3\lib\tempfile.py", line 256, in _mkstemp_inner
    fd = _os.open(file, flags, 0o600)
PermissionError: [Errno 13] Permission denied: 'D:\\software\\python3\\anconda3\\Lib\\site-packages\\pytest_html\\__pycache__\\tmp_ttoasov'

During handling of the above exception, another exception occurred:

pytest_html\\pycache\\tmp_ttoasov 没有这个文件删除这个文件夹再试试

1.2错误原因

1、文件被占用

2、文件找不到

3、无权限访问

4、打开的不是文件，而是一个目录

D:\software\python3\anconda3\Lib

Python 3.6 解决&quot;PermissionError: [Errno 13] Permission denied&quot; - 简书

管理员方式运行 pycharm

import pytest

if __name__=='__main__':

    pytest.main(['-s','-v', './test_project','--html=./report/result.html'])

3. 用例并行执行 pytest-parallel

pip install pytest-parallel

运行： pytest -q test_paralle.py

web 自动化并行执行可能会相互干扰。少用
