Hi all,

I was using JMeter for a while, but found JMeter does not handle misconfiguration well in many cases.

Specifically, when users provide a wrong configuration option and JMeter produces a wrong result (or crashes), JMeter should explicitly dump error message pointing to the mis-configured option, rather than failing silently, or dumping stack traces, or simply restoring to the default behavior.

I have found many places in JMeter which can be improved, to give users better experience.

As a very simple example, JMeter permits users to specify the output file format via: "jmeter.save.saveservice.output_format"   option (the legal values can be "xml" or "csv").

However, if a careless user types "jmeter.save.saveservice.output_format = xxxml" or other unsupported file format, JMeter will automatically restore to using "CSV" format without notifying users that they provide a wrong configuration option value. This occurs to me a few times, and makes me really confused.

I believe such places should be further improved to make JMeter more user-friendly.

I found a couple of such places. and wondering whether JMeter developers would like to know them, and how do you think about such "mis-handling"?

Thanks
