I started crafting my simulations using https://gist.github.com/groovybayo/4691670 to bootstrap the whole project, thinking I would be able to just run gatling from the command-line under CI. Once I had a complete simulation working, complete with composition and some run-time behavior controls, my next task is to get it running from the command-line.
I wrote a wrapper script to pass the configuration settings based on Engine.scala, wrapper.sh.
–wrapper.sh--------------------
export GATLING_HOME=/kando/server/gatling
export GATLING_CONF=${GATLING_HOME}/src/test/resources
TARGET=${GATLING_HOME}/target
RESULTS=${TARGET}/results
REQUESTS=${GATLING_CONF}/request-bodies
BINARIES=${TARGET}/test-classes
SOURCES=${GATLING_HOME}/src/test/scala/com/company/group/gatling/simulations
DESCRIPTION=nutty
#echo running TestSimulation via Gatling
-s ${SIMULATION}
#cmd="${GATLING_HOME}/bin/gatling.sh -rf ${RESULTS} -bf ${REQUESTS} -sbf ${BINARIES} -sd ${DESCRIPTION}"
cmd="${GATLING_HOME}/bin/gatling.sh -rf ${RESULTS} -bf ${REQUESTS} -sf ${SOURCES} -sd ${DESCRIPTION}"
echo ${cmd}
${cmd}
–wrapper.sh--------------------
I have my project organized as follows:
src/test/scala/com/company/group/gatling:
- core/
- services/
- simulations/
- titles.title/
- tools/
with Engine, IDEPathHelper, & Recorder under src/test/scala.
Took me a few runs (and digging into the Gatling source) that -sbf & -sf are mutually exclusive.
When run as above, I get the following errors:

I’ve tried, instead, to run using the binaries compiled from the IDE. That simply results in this error:

My preference would be to have gatling build the sources on the fly and not have to re-org all the classes. I will if I have to, though.
