选择在JavaScript执行后可用的单选按钮

Question

我的测试用例是预约。问题是，我必须选择的必需单选按钮（对表单是强制性的）可以通过JavaScript函数getTimeSlots()

使用

这是具有功能和输出的Webdeveloper控制台

在这里，WebDeveloper控制台向我显示了约会页面的单选按钮

在我的理解中，我转到约会页面，执行javascript并选择单选按钮并提交表格。但这是行不通的。

Book appointment
    [Tags]  appointment
    Input Text  id:foo  here is bar
    Input Text  id:bar  here is more bar
    Click Element  id:requested_date
    # Get date out of the datepicker
    ${current_date_noon} =  Get Current Date  result_format=%Y-%m-%d 00:00:00
    ${date_in_7d} =  Add Time To Date  ${current_date_noon}  7 days
    ${unixtime} =  get time  epoch  ${date_in_7d}
    ${data_format} =  Set Variable  ${unixtime}000
    Click Element    xpath=//td[@data-date="${data_format}"]

    # FIXME Here I try to select the radiobutton
    Execute Javascript  window.getTimeSlots()
    #Select Radio button  requested_time  19:00 - 19:30
    Click Element  name:requested_time
    Capture Page Screenshot  Screenshot-termin-buchen-{index}.png
    Submit Form

运行代码时，我在控制台中得到以下结果

Book appointment                                                      | FAIL |

如何使用机械手框架选择此单选按钮？

Answer 1

好吧，出现此错误有多种原因。通常，这意味着交互之间DOM的状态发生了变化。由于以SeleniumLibrary 3.3开头的关键字Wait Until不会因此错误而失败。您可以尝试等到元素存在，然后单击它。
