如何在断言失败时延迟HTTP请求 - 在记录的jmeter脚本中

时间：2016-02-24 22:45:54

标签： jmeter load-testing

我有一个用于我的Web应用程序负载测试的录制脚本。在其中一个HTTP请求中，我需要检查“已完成”状态文本的响应消息。如果状态不是“已完成”，那么我需要运行一次循环5次以检查状态是否为“已完成”。

我知道断言我可以检查“已完成”状态但不确定如何在转移到下一个HTTP请求之前使HTTP请求等待并检查循环5次。

任何帮助将不胜感激。谢谢！

您可以使用循环控制器 + 如果控制器来满足您的要求。

测试计划应该几乎如下所示。

enter image description here

让我们假设我们有一个变量completed.status = false

如果条件应为"${completed.status}"=="false"，则默认情况下首先调用以获取状态。

Beanshell断言应该在条件满足时更改completed.status = true。

如果不满足条件 - Beanshell应为计时器vars.put("wait", "3000")创建另一个变量。使用${wait}计时器等待3秒钟再拨打一个电话。因此，如果第一个呼叫本身的状态为“已完成”，则定时器不会延迟!!

请查看实施上述逻辑的附件样本测试计划。
