RobotFramework seleniumlibrary 在网络命名空间中打开无头浏览器

Question

我需要在我的设置中使用网络命名空间，它工作得很好。
但是，当涉及到通过 seleniumLibrary 进行测试以打开浏览器并测试网络界面时，我似乎无法让它与网络命名空间一起工作。

我可以通过运行ning firefox 在命名空间中手动运行 firefox，它可以访问指定命名空间的网络。
我如何在 RobotFramework 中使用 seleniumLibrary 执行此操作？

我有这个 atm：

*** Settings ***
Documentation   Test browser access in netns

Library   OperatingSystem
Library   SeleniumLibrary

Force Tags  test_123

*** Test Cases ***
Test Browser In Netns
    Open Browser    192.168.0.100  browser=ff
    Close Browser

运行这会产生错误：\

WebDriverException: Message: Service geckodriver unexpectedly exited. Status code was: 69

运行这个外部网络命名空间没有产生任何错误，并且 100% 通过。

Answer 1

创建 netns 时不会自动添加和向上环回。
这需要加上ip netns exec net-$name ip link set dev lo up。
GeckoDriver 将尝试将自己绑定到 127.0.0.1 上的随机端口，因此 lo 不启动，它自然会失败。
