Test deployment of models
${response} deploy model from file ${CURDIR}/../../bpmn/demo_for_robot.bpmn
Starting a process instance
*** Settings ***
Library CamundaLibrary ${CAMUNDA_HOST}
*** Variables ***
${CAMUNDA_HOST} http://localhost:8080
*** Test Cases ***
Test starting process
#GIVEN
${process_definition_key} Set Variable demo_for_robot
# WHEN
${process_instance} start process ${process_definition_key}
Execute Task
"Executing task" bascialy means, you execute a robot task that fetches a workload from camunda, processes it and returns its workload back to camunda during completion. Main keywords involved are:
