Docker Bamboo代理中Robot Framework+Selenium无法下载JSON文件

Robot Framework测试下载文件失败问题解决

报错信息

关键字'File Should Exist'重试10次后失败。
最后一次错误信息：文件'/tmp/downloads/importResults.json'不存在。

背景信息

测试在Docker（docker-compose）部署的Bamboo代理环境中运行
DOWNLOAD_DIR配置为/tmp/downloads，已从主机挂载到容器内部
测试执行完成后，容器内及主机上的该目录均为空
根因：Chrome默认将JSON响应在页面内打开而非触发下载，仅配置download.default_directory不足以改变这一行为

修复方案

更新login.resource文件，扩展Chrome偏好设置，添加强制下载JSON文件的配置：

Login into Site with User and Password
    [Documentation]     打开站点并使用指定凭据登录（无SSO）
    [Arguments]     ${username}     ${password}     ${MFA_KEY}
        ${BROWSER_TYPE_DEFINED}          Get Variable Value    ${BROWSER_TYPE}
        # 如果设置了DOWNLOAD_DIR（比如Bamboo代理环境变量）则使用，否则默认用EXECDIR（本地执行目录）
        ${DOWNLOAD_DIR} =    Get Variable Value    ${DOWNLOAD_DIR}    ${EXECDIR}
        Set Suite Variable    ${DOWNLOAD_DIR}    ${DOWNLOAD_DIR}
        # 新增配置：强制Chrome下载JSON文件，而非在页面打开
        ${prefs}=    Create Dictionary    download.default_directory=${DOWNLOAD_DIR}
        ...    download.prompt_for_download=False
        ...    download.directory_upgrade=True
        ...    plugins.always_open_pdf_externally=True
        ...    plugins.plugins_list=[{"enabled":False,"name":"Chrome PDF Viewer"}]
        ...    text/json=${DOWNLOAD_DIR}
        ...    application/json=${DOWNLOAD_DIR}
        IF  "${BROWSER_TYPE_DEFINED}" == "CI"
            Open Browser   ${URL}   Headless Chrome     options=add_experimental_option('excludeSwitches', ['enable-logging']);add_experimental_option('prefs', ${prefs});add_argument('--headless');add_argument('--no-sandbox');add_argument('--disable-dev-shm-usage')   remote_url=${BrowserServers["CI"]}
        ELSE
            Open Browser    ${URL}   ${Browsers["${Browser}"]}     options=add_experimental_option('excludeSwitches', ['enable-logging']);add_experimental_option('prefs', ${prefs})
        END
        Set Default Browser Window Size
        Set Global Script Timeout

Bamboo脚本代码

注：原配置中bamboo.DOWNLOAD_DIR存在拼写错误/tmp/downlodas，已修正为/tmp/downloads

export TOTAL_AGENTS_COUNT=${bamboo.TOTAL_AGENTS_COUNT}
export MFA_KEY=${bamboo.AGENT0_MFA_KEY_ADMIN}
export DOWNLOAD_DIR=${bamboo.DOWNLOAD_DIR}
echo "here: $MFA_KEY"
echo "--suite xray-settings-graphql" > scripts/run_test.cfg
echo 'List of suites in current run_config_process_1.cfg file:'
cat scripts/run_config_process_1.cfg
echo 'Run Tcs'
ls -ld /tmp/downloads
echo "hello" > /tmp/downloads/testfile.txt
cat /tmp/downloads/testfile.txt
