机器人框架：使用“关闭所有浏览器”时，套件拆解失败

我正在使用chromedriver ， 机器人框架与SeleniumLibrary ，所有测试工作正常，但套件拆解失败。 我似乎无法找出原因。 非常感谢帮助。 日志显示：

家庭套房拆解失败：BadStatusLine：''

已安装的版本

• chromedriver 2.45.615291
• 机器人框架3.1.1
• python 2.7.12
• SeleniumLibrary 3.3.1
• Selenium 3.141.0

我注销了导致BadStatusLine错误的原因，我希望这有助于找到解决方案

你正在使用的硒版本可能导致这种情况。

• 请参阅： https ： //github.com/robotframework/robotframework/issues/2137

要查看哪些版本的selenium支持您正在使用的python版本，请查看。 https://github.com/robotframework/SeleniumLibrary/blob/master/README.rst#support

*** Settings ***
Suite Setup    Open Database Connection
Test Setup     Login
Suite Teardown    Suite shutdown
Library    SeleniumLibrary

*** Test cases ***
...
...

*** Keywords ***
Suite shutdown
    Disconnect from Database
    Close All Browsers

Answer 2

快速修复将向您的套件拆分添加Run Keyword And Ignore Error它仍然会执行有效的命令，但会跳过错误命令

*** Settings ***


Library  Selenium2Library
Suite Teardown   Run Keyword And Ignore Error  Suite shutdown



*** Test Cases ***
Test Keyword
    Open Browser  http://google.com  chrome

*** Keywords ***
Suite shutdown
     Erro1234r # This should fail due to no keyword named Erro1234r, it skips this and closes all browsers
     Close All Browsers

错误BadStatusLine: ''从python的httplib传播 - http通信的核心模块（显而易见的是它的名字:)），并且来自selenium和浏览器webdriver之间通信中的错误。
它与Robot Framework的SeleniumLibrary / Selenium2Library没有任何联系 - 它只是一个包装器（我必须承认的一个非常好的包装）在selenium库上。

因此，在这个方向上查找错误 - 已安装的selenium库的版本与安装的chromedriver不chromedriver - 一个发送到其他数据，这对于收件人来说是意外的。
我建议升级到两者的最新版本 - 当一个（明显）比另一个更新时，会发生这种打嗝。
