机器人框架：使用关闭所有浏览器时套件拆解失败

Question

我将 chromedriver、robotframework 与 SeleniumLibrary 一起使用，所有测试都运行良好，但套件拆解失败。我似乎无法找出原因。帮助将不胜感激。 日志显示：

父套件拆解失败：BadStatusLine: ''

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

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

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

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
• 硒 3.141.0

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

Answer 1

您使用的 selenium 版本可能会导致此问题。

• 见：https://github.com/robotframework/robotframework/issues/2137

要查看哪些版本的 selenium 支持您使用的 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

快速解决方法是将Run Keyword And Ignore Error 添加到您的 Suite Teardown 中，它仍然会执行有效的命令，但会跳过类似这样的错误命令

*** 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

Answer 3

错误BadStatusLine: '' 传播自 python 的 httplib - http 通信的核心模块（从它的名字可以明显看出 :)），并且来自 selenium 和 webdriver 之间的通信错误浏览器。
它与 Robot Framework 的 SeleniumLibrary/Selenium2Library 没有任何关系——它只是 selenium 库的一个包装器（我必须承认它非常好）。

因此，寻找那个方向的错误 - 您安装的 selenium 库的版本与已安装的 chromedriver 无法正常工作 - 一个发送到另一个数据，这对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（显着）比另一个更新时，确实会发生这种问题。
