How to get the complete log for bean shell scripts in jmeter

问题

I am using Apache JMeter 3.1 and in my test suite I have a BeanShell PreProcessor. When I run the scrip, in the Log Viewer I can see there are errors in the bean shell script. But the error message is very limited, how can I get the complete error?

For example, an error I see in the Log Viewer is as follows,

ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval Sourced file: inline evaluation of: ``// Following is a sample for input // "abc.org/def/xyz . . . ''

Is there a way I can retrieve the complete error?

回答1:

You can enable debug output in at least 2 ways:

• Adding debug() directive to the beginning of your Beanshell script - debugging output will go to STDOUT (JMeter console)

• Putting your code inside the try block like:

  try {
      //your code here
  }
  catch (Throwable ex) {
      log.error("Something went wrong", ex);
      throw ex
  }
  

  This way full exception stacktrace will be available in jmeter.log file

I would rather recommend switching to JSR223 Elements and Groovy language as Groovy is more Java-compliant and provides better performance. See Groovy Is the New Black for details.
