如何解决机器人框架中的 urlopen 错误？

Question

代码 下面是计算器android程序测试使用robotframework AppiumLibrary的示例代码

*** Settings ***
Library           AppiumLibrary     run_on_failure=Log Source
#Library           Selenium2Library
#Library           OperatingSystem

#Setup    Open    Calculator
#Teardown    Close    Application

*** Variables ***
${DEV.APPIUM_SERVER}    =   https://127.0.0.1/wd/hub
${DEV.PLATFORM_VERSION}     =   7.0.1
${DEV.PLATFORM_NAME}    =   Android
${DEV.DEVICE_NAME}  =   device1 
${DEV.PACKAGE_NAME} =   com.google.android.calculator
${DEV.ACTIVITY_NAME}    =   com.android.calculator2.Calculator

#Elements locators for various
${EQUALS_SIGN}  =   xpath=//*[contains(@text,'=')]
${DISPLAYED_RESULT} =   xpath=//*[contains(@resource-id,'id/result')]


${td_Digit1}    =   5
${td_Digit2}    =   2
${td_Expcted_Addition_Result}   =   7
${td_Expected_Subtraction_Result}   =   3

上面的代码运行后出现以下错误

测试用例 1：加法 URLError:urlopen 错误未知 url 类型：= http

Appium 服务器已经在系统中运行。请帮我找出错误

Answer 1

缺少 AppiumServer URL 上的端口，来自示例：

http://localhost:4723/wd/hub

在你的情况下（如果真的是 HTTPS 到 localhost），也许你可以试试：

http://127.0.0.1:443/wd/hub
