JMeter从入门到荒废-常见问题汇总

启动某个ThreadGroup的时候，启动不了

现象

1. 点击start按钮的时候，结果树和汇总报告都没有任何数据。
   

2. 同时，点击右上角的error log
   
   发现有错误信息：
   错误信息如下：

原因：

1. 在排查过程中，进行了各种设置，都不能生效。

2. 最终发现是，测试计划是有Enable和Disable按钮。现在是Disable的状态
   

3. 同时，Disable的状态，点击start按钮启动的时候，JMeter也不会提示执行计划不是Enable的状态，无法启动。

解决方案

1. 把测试计划，从Disable状态改为Enable状态
