Why the tcp keep-alive connection will be automaticly closed after the junit sampler was executed by jmeter?

[Ma Haiyin]

I has written a junit case that create a tcp keepalive connection and send a simple string.

But when I run the junit case in jmeter, I found that the tcp connection object will be disposed and closed after the test case was executed.

Although I have tried to resolve it, I can‘t find any usable information.

Maybe the problem can be stated as "How to test the tcp keepalive connection by using Jmeter JUnit Sampler instead of Jmeter tcp sampler?"

I faced the same problem with TCP sampler (jmeter), socket is closed after request even when we used "re-use connection". 

Did you find useful "JUnit Request"?

Thanks,
