Instance Migration Tests

These modules test scenarios in which process instances are started before upgrading Camunda from a minor version to another minor version and completed after. The tests ensure that object instances persisted in the database tables by the engine in a previous minor version can be successfully processed by succeeding versions. The most common use case is migration of execution trees.

Executing Tests

Run mvn clean install -Pinstance-migration,${database-id} where ${database-id} is for example h2.

Running tests with the Maven Wrapper

With mvnw, from the root of the project, run: ./mvnw clean install -f qa/test-db-instance-migration/pom.xml -Pinstance-migration,${database-id} where ${database-id} is for example h2.

Project Structure

• test-fixture-72: Creates the 7.2.0 database schema
• Any test-fixture-7x: Applies patch scripts for version 7.(x-1). Applies migration scripts from 7.(x-1) to 7.x. Starts process instances with engine version 7.x.0
• test-migration: Executes test cases to assure that process instances started by any of the test-fixture modules can be completed with the current engine version
