java参数化selenium junit中的一个变量，以加载测试在jmeter上运行的网站

Question

我需要加载测试一个执行XHR对象的网站。 正常的负载测试在这种情况下不适用，因为负载测试寻找的是服务器端，而我对客户端感兴趣

我唯一需要参数化的是用户名，以使脚本同时运行

我确实使用了Katalon Recorder以JUnit的形式获取自动化代码，然后将其输入selenium，然后将其导出为jar文件，并在Jmeter中使用

该代码适用于单个用户，但我想不出一种方法来让脚本同时运行

在当前状态下，页面会为单个用户保守地加载，一旦页面中的元素被加载，它就会移动到下一个页面，以此类推

您需要将脚本链接到ApacheJMeter_core library。这将允许您访问JMeterContext类，该类通过JMeterVariables类提供对JMeter Variables的读/写访问

相关代码如下所示：

JMeterVariables vars = JMeterContextService.getContext().getVariables();
String username = vars.get("username"); // this will read `${username}` JMeter Variable
