Question

打开浏览器$ {REMOTE_URL} $ {HEADLESS}

我想从命令行将headlesschrome值传递给Open Browser关键字

Answer 1

如果您想使chrome无头工作，则以下代码应该可以工作。当您想要参数化时，请放弃此文档-https://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#resource-and-variable-files

创建所有变量并将其存储在文件中，然后，在调用以下任何代码时，请使用以下语法，或，从命令行传递如下所示的各自的name：value，以使其在机器人代码中使用

robot -v <<variable file>> *.robot

OR

robot -v name:value *.robot

更好的方法

Xvfb是X窗口系统的无头显示服务器，相反，如果使chrome / firefox无头运行，为什么不使用以下方法。

安装用于Robot Framework的XvfbRobot库，这是一个用于创建虚拟显示的机器人库，可用于在无头模式下运行硒测试。

pip install robotframework-xvfb

示例

*** Test Cases ***
Create Headless Browser
    Start Virtual Display    1920    1080
    Open Browser   http://google.com
    Set Window Size    1920    1080
    ${title}=    Get Title
    Should Be Equal    Google    ${title}
    [Teardown]    Close Browser
