Python 机器人无效 Return 来自关键字用法

Question

我正在尝试在 Robot 中执行以下代码并遇到以下错误。我很难找出问题所在

${job_id}=    Run Keyword And Return If    "${cur_build}" != "<my_Build>"    perform software upgrade    ${wd}    <device_name>    <my_build>

下面是 xml 输出。

编辑

所以我明白了运行 Keyword 和 Return if 只能用在 Keywords 中，不能用在 Testcase 中。但是，我将如何在测试用例中执行以下操作

if <some_cond>:
   ${my_var}=    <Keyword A>
   Keyword B=    ${my_var}

一种方法是添加定义新关键字，但是有没有办法在测试用例中执行此操作而不定义任何新关键字

请让我知道以下代码是否符合您的目的

*** Variables ***
@{list1}          @{EMPTY}
@{list2}          This    is    list    list1

*** Test Cases ***
Conditional Test Case1
    ${flag}=    Set Variable If    @{list1}!=@{EMPTY}    ${true}    ${false}
    ${rc}=    Run Keyword If    ${flag}==${true}    Log Multiple Values    ${list1}
    ${rc}=    Run Keyword Unless    ${flag}==${false}    Log Multiple Values    ${rc}

Contitional Test Case2
    ${flag}=    Evaluate    len(${list2}) is not None
    ${rc}=    Run Keyword If    ${flag} == ${true}    Log Multiple Values    ${list2}

*** Keywords ***
Log Multiple Values
    [Arguments]    @{list_args}
    [Documentation]    This keyword logs its arguments and also returns them
    Log Many    @{list_args}
    [Return]    @{list_args}
