Hibernate optional query testing

The purpose of this project is to test if Hibernate Reactive can handle optional queries. This idea came by reading https://www.baeldung.com/spring-data-jpa-null-parameters and https://stackoverflow.com/questions/2488930/passing-empty-list-as-parameter-to-jpa-query-throws-error.

NOTE: All Hibernate Reactive test are done with Mutiny.

Formatting

Prerequisite: Npm

Formatting is done by prettier and its plugins:

npm ci
npx prettier --write .

Running the application

Prerequisite: Java, maven and docker (testcontainers)

Tests

Test are ran either from each subproject or form the parent project with the command below

mvn clean test --fail-at-end

Each test launches a postgres in a testcontainer on a random port and each of them loads the import.sql script with the help of Hibernate.
