如何在JMeter中使用Bean Shell断言将数据库查询结果与字符串进行比较

Question

我是JMeter的新手。

在我的测试计划中，我使用

1. 用于连接SQL数据库的JDBC连接配置。

2. JDBC请求以运行选择查询。而且我使用了“变量名”字段来存储数据库响应中的FK_SiteId，如下所示。

3. 我使用了Debug Sampler来在结果中打印FK_SiteId。请找到调试结果。

4. 我正在使用BeanShell断言来比较实际FK_SiteId与预期FK_SiteId，如下所示。

请在下面找到错误消息。

谁能告诉我我要去哪里了

Answer 1

您的变量已保存为FK_SiteId_1。您可以通过以下方式访问此变量：

vars.get("FK_SiteId_1")或直接${FK_SiteId_1}

使用log.info(...检查变量值

我更喜欢使用vars.get解决方案。
