Pytest x-dist INTERNALERROR 尝试使用 ssh 在远程 Windows 主机上进行 运行 测试
Pytest x-dist INTERNALERROR when trying to run tests on remote Windows host using ssh
我有 Ubuntu 主机环境：
Python 3.6.9，pytest-4.6.9，execnet 1.7.1，x-dist 1.31.0
和 Windows 主机：Windows 版本 10.0.19041.508，python 3.7.5，pytest 5.4.1，execnet 1.7.1
我想在 Ubuntu 的 Windows 主机上 运行 测试，使用 x-dist 插件：
pytest -v -d --tx ssh=admin@10.15.20.15 --rsyncdir /etc/ansible/autotests/release C:\users\Public\test_create_session.py
我收到错误：

当我 运行 在其他 Windows 主机上进行相同的测试时，一切正常，没有错误。我认为这个 Windows 主机响应出乎意料，但我不明白是什么问题。有人可以帮助我吗？
问题出在远程 Windows 主机上。系统没有 python 解释器（在环境变量 Path 中）的路径（仅供用户使用）。我在系统的 Path 环境变量中添加了 Python 和 Pytest 的路径，它起作用了！
我是如何找到这个的：
我制作了一个简单的脚本来检查 execnet（远程代码执行）是否工作：
import execnet, os
gw = execnet.makegateway(ssh="admin@10.15.20.15")
channel = gw.remote_exec("""
import sys, os
channel.send((sys.platform, tuple(sys.version_info), os.getpid()))
""")
platform, version_info, remote_pid = channel.receive()
print(f"Platform: {platform}, Version Info: {version_info}, Remote Pid: {remote_pid}")
这个脚本没有用，我意识到问题不在pytest，而是在远程主机，无法执行代码。这样我就开始检查系统变量
