Spring Boot application is not covered by tests

[munterfi]

When Dependabot proposes updates for dependencies, the current build passes successfully even if the Spring Boot application fails to start.

So we should add a Spring Boot Test, which also starts the application.

Example: Dependabot PR #139 passes, but while running the application locally or during CI/CD, the Spring Boot application crashes with the following error:
