Robot Framework跨关键字传参方法及传值失败排查

你的脚本存在3个直接导致变量传递失败的错误：

• 为creating the merchant关键字错误声明了入参${randomMerchantName}：该变量是关键字内部生成的，不需要外部传入，且你调用关键字时未传对应参数，本身就会触发参数缺失报错；同时同名局部变量会覆盖后续Set Suite Variable的作用域，导致全局变量设置失效。
• 虽然为creating the merchant配置了返回值，但测试用例调用该关键字时未接收返回值，后续delete merchant也没有定义入参接收变量，无法拿到生成的商户名。
• 删除关键字逻辑里的断言部分漏写了变量前缀$，{merchant_delete_PopUpmessage}会被识别为普通字符串而非变量，也会触发执行报错。

给两种可直接运行的实现方式，按需选择即可：

方案1：基于套件作用域变量传递（匹配你原本的实现思路） #

删除creating the merchant中多余的入参声明，修正变量拼写错误即可，修正后完整代码：

***** Test Cases *****
create merchant
    Given creating the merchant
    Then delete merchant

***** Keywords *****
creating the merchant
    ${random_number}     Generate Random Number
    Set Suite Variable    ${random_number}
    Fill Text    ${new_MerchantId}      ${random_number}
    ${randomMerchantName}    Generate Random Name    ${8}
    Set Suite Variable    ${randomMerchantName}
    Fill Text   ${new_MerchantName}     ${randomMerchantName}
    Fill Text    ${orgNumber}       23421
    Click    ${new_merchantAddButton}
    Click    ${PopUp_Okbutton}

delete merchant
    Click   ${Agreement_titlecontainer}
    Click    ${back_button}
    Sleep    10s
    Fill Text    ${MerchantName}    ${randomMerchantName}
    Click    ${merchant_SearchIcon}
    Click    ${Merchant_deleteIcon}
    Get Text    ${merchant_delete_confirmationPopUp}     *=     ${merchant_delete_PopUpmessage}
    Click    ${PopUp_Okbutton}
    Click    ${PopUp_Okbutton}

方案2：基于返回值+入参传递（更推荐，作用域清晰无全局污染） #

不使用全局套件变量，创建商户关键字返回生成的随机名称，删除商户关键字显式声明入参接收变量，用例层完成值传递，可维护性更强，修正后代码：

***** Test Cases *****
create merchant
    Given creating the merchant
    ${merchant_name}    creating the merchant
    Then delete merchant    ${merchant_name}

***** Keywords *****
creating the merchant
    ${random_number}     Generate Random Number
    Fill Text    ${new_MerchantId}      ${random_number}
    ${randomMerchantName}    Generate Random Name    ${8}
    Fill Text   ${new_MerchantName}     ${randomMerchantName}
    Fill Text    ${orgNumber}       23421
    Click    ${new_merchantAddButton}
    Click    ${PopUp_Okbutton}
    [Return]    ${randomMerchantName}

delete merchant
    [Arguments]    ${randomMerchantName}
    Click   ${Agreement_titlecontainer}
    Click    ${back_button}
    Sleep    10s
    Fill Text    ${MerchantName}    ${randomMerchantName}
    Click    ${merchant_SearchIcon}
    Click    ${Merchant_deleteIcon}
    Get Text    ${merchant_delete_confirmationPopUp}     *=     ${merchant_delete_PopUpmessage}
    Click    ${PopUp_Okbutton}
    Click    ${PopUp_Okbutton}
