The project allows to test different process instance versions running after the sample acme application upgrade.

Prerequisites

• Containerization software e.g. Docker desktop
• bash shell

How to run

./run_test.sh

How does it work

	#!/bin/bash
	set -e
	echo '--- Testing upgrade from release-0.1.0 -> release-0.2.0'
	# start postgres database to store version 0.1.0 data

	# generate v 0.1.0 data
	./mvnw --projects release-0.1.0 clean test -Dspring.profiles.active=generateData

Generate data for release 0.1.0:

The tests on the process instance from version 0.1.0 performed on the version 0.2.0.
