Definition of Done

In order to verify work is done:

• Checkout the branch
• Run the whole project with ./mvnw clean verify -DskipTests
• Change to the project: cd datasafe-storage/datasafe-storage-impl-s3/
• Run the module without skipTests ../../mvnw clean verify. Check accurate number of tests is run
• Start docker and run the module without skipTests ../../mvnw clean verify -PIT. Check accurate number of tests is run

Repeat this for each subproject of datasafe storage that might have an integration test.
