【问题描述】：

有人可以发布示例代码来创建两个浏览器实例并在使用 Robot Framework 的浏览器（不使用 SeleniumLibrary）库之间切换吗？

即：如何为Switch Browser关键字获取正确的browser id。

Switch Browser ${browser_id}

到目前为止的完整代码：

Library          Browser
Library          String
Library          Collections

** Variables **
${url1}=    https://www.google.com
${url1}=    https://www.bing.com
@{browser_ids}=    Create List

** Test Cases **
Open Browser 1
    [Tags]   UI    dev
    New Browser    chromium    headless=false
    New Context    viewport={'width': 1920, 'height': 1080}
    New Page       ${url1}

Open Browser 2
    [Tags]   UI    dev
    New Browser    chromium    headless=false
    New Context    viewport={'width': 1920, 'height': 1080}
    New Page       ${url2}

** Keywords **
Switch to Browser2
    Switch Page    ${browser_ids}[1]

Switch to Browser1
    Switch Page    ${browser_ids}[0]

Store Active Browser Id
    ${active_id}=    Get Page Ids   ACTIVE    ACTIVE    ACTIVE
    Log To Console    ${active_id}
    ${active_id}=    Split String    ${active_id}[0]    =
    Log To Console    ${active_id}[1]
    Append To List    ${BROWSER_IDS}    ${active_id}

浏览器库具有浏览器/上下文/页面实例的自动拆卸功能，因此您必须在套件设置中创建所有需要的实例。解决方法如下：

*** Settings ***
Library          Browser
#Library          OperatingSystem
Library          Collections
Library          String
Suite Setup      Create Suite Ecosystem

*** Variables ***

@{bids}
@{cids}
@{pids}
${url1}=    https://www.google.com
${url2}=    https://www.bing.com

*** Test Cases ***

Setup Verification
    [Tags]   UI    dev
    ${bids}=   Get Browser Ids
    Log To console    ${bids}

    ${bids}=   Get Context Ids
    Log To console    ${cids}

    ${pids}=   Get Page Ids
    Log To console    ${pids}

    #${active_id}=    Split String    ${active_id}[0]    =
    Log To Console    ${active_id}[0]
    Append To List    ${bids}    ${active_id}[0]

Store Active Context Id
    ${active_id}=    Get Context Ids   ACTIVE    ACTIVE

    Log To Console    ${active_id}[0]
    Append To List    ${cids}    ${active_id}[0]
