How to pring/log the build-in exception stack trace?

[Jobs Lam]

I write an library with Python. 

A build-in expcetion was rasied when I debug some funtion in robot.But I could not know the line that occured.

Because only the exception message have been logged but not the exception stack trace .

How can the robot framework log/print the build-in exception stack trace that rasied in python?

[Kevin O.]

use the arguments to the runner:

--loglevel DEBUG

This will cause stacktraces to be appear in the log.

see http://robotframework.googlecode.com/hg/doc/userguide/RobotFrameworkUserGuide.html?r=2.8.4#debugging-problems
