如何在 Robot Framework 中清除或删除列表中的值

Question

我写了一个测试用例，它会从 excel 表中读取登录详细信息，并为每对详细信息登录和注销。

我正在从 Excel 中读取数据，每行详细信息都传递给列表并将其作为输入发送到另一个关键字/函数以进行登录。

注销后，我只想删除列表中的值，它显示为成功，但在下次运行时它也显示旧值。

我搜索了，我没有得到任何关键字来清除所有列表值。

有人可以帮我解决这个问题吗？代码如下：

在输出中它显示为删除值，但下一次运行，它也显示旧值

Answer 1

尝试使用关键字“创建列表”作为 FOR 循环的最后一步，而不是“删除值”用户定义的关键字。此外，如果每行的列数不同，请将变量 ${cellCount} 移动到循环内

    Get Data from Excel
    Open Excel Sheet    ${excelName}
    @{sheetNames}    Get Sheet Names
    ${sheetName}    Set Variable    @{sheetNames}[0]
    ${rowCount}    Get Row Count    ${sheetName}

    : FOR    ${rindex}    IN RANGE    1    ${rowCount}
    \    ${cellCount}    Get Column Count    ${sheetName}
    \    @{rowValues}    Get Values    ${sheetName}    ${rindex}    ${cellCount}
    \    Log to console    row values are for index ${rindex} : @{rowValues}
    \    Login to the CLM    @{rowValues}
    \    Log    cell count is : ${cellCount}
    \    Change Language to English
    \    Sleep    ${delay}
    \    Logout from CLM
    \    @{rowValues}    Create List

“@{rowValues} 创建列表”：此命令将清除列表中的值

Answer 2

在我的情况下，我想要清除的列表是全局的，所以我无法使用 Create List 清除它。在这种情况下，一个

:FOR     ${elem}    IN    @{list}
    Remove values from list    ${list}    ${elem}

帮助。
