我使用Robot Framework.

在我的HTML页面上,我有一个简单的按钮.单击它时,它会下载pdf文件.

如果文件已下载,我如何查看Robot Framework？

TKS

我找到了一个解决方案,请转到@ ombre42：

${SERVER}                  ${SERVER_DEV}
${NAME}                 Robot
${FILE_NAME}                Robot.pdf
${CLASS_NAME}               in
${DOWNLOAD_DIRECTORY}       C:robot_download

Scenario: User can download
    Create Directory    ${DOWNLOAD_DIRECTORY}
    ${CHROME_OPTIONS}=  Evaluate    sys.modules['selenium.webdriver'].ChromeOptions()   sys,selenium.webdriver
    ${disabled} Create List     Chrome PDF Viewer
    ${prefs}    Create Dictionary   download.default_directory=${DOWNLOAD_DIRECTORY}    plugins.plugins_disabled=${disabled}
    Call Method ${CHROME_OPTIONS}   add_experimental_option prefs   ${prefs}
    Create Webdriver    Chrome  chrome_options=${CHROME_OPTIONS}
    Goto    ${SERVER}
    Click Element ${NAME}
    Wait Until Element Is Visible   css=div.${CLASS_NAME}   8
    Page Should Contain ${NAME}
    Set Selenium Speed  10s
    Download PDF    ${NAME}
    File Should Exist   C:robot_download${FILE_NAME}

解决方法

该解决方案非常适合浏览器.对于Chrome,您可以告诉Chrome在哪里下载文件.选择新文件夹可以监视下载的状态.此外,由于您正在下载PDF,因此需要禁用PDF插件以防止显示PDF而不是下载PDF.这是一个使用简单页面和PDF文件在我的机器上运行的测试.
