Blazemeter：属性未在线程组之间交换

提问于

我正在使用JMeter测试API，它在本地工作正常 . 但是，当我将测试计划和参数文件上传到Blazemeter时，它运行不正常并抛出错误

javax.script.ScriptException：ReferenceError：第1行未定义“getFinancialDashboard_responseCode”

在日志中 . getFinancialDashboard_responseCode 是我在前一个线程组中定义的属性，其值被传递给拆解线程组，以根据响应代码将通知推送到消息传递应用程序 .

我试图在Blazemeter上的测试配置中定义此属性，但这有不同的用途，即覆盖该值 . 在Blazemeter上的配置中定义此属性会使测试成功执行，但会覆盖线程组中设置的当前值并使其发送不需要的通知 .

这是完整的异常日志：

如何处理Blazemeter中的属性，以便可以在线程组之间交换值？

    我强烈怀疑你的测试“在本地工作正常”，因为很可能你已经配置了你的If控制器：

    JMeter If Controller - BAD

    这在JavaScript方面是不正确的 . 如果 really 已在某处定义 getFinancialDashboard_responseCode ，则应使用以下条件：

    ${__groovy(!props.get('getFinancialDashboard_responseCode').equals('200'),)}

    还要确保选中 Interpret Condition as Variable Expression? 框：

    JMeter Groovy

    更多信息：6 Tips for JMeter If Controller Usage

    如果您因任何原因想继续使用JavaScript，则需要将您的条件修改为：

    • 使用__P() function获取属性

    • 环绕属性函数调用， 200 用引号括起来：

    "${__P(getFinancialDashboard_responseCode,)}" != "200"

    但请注意，从性能角度来看，与Groovy相比，JavaScript工作得更糟 .

    另外请注意，您应该能够接触到BlazeMeter Support，它应该更快，获得真正的专业响应的机会将远远高于社区论坛 .
