An overview of a sample Java EE application
We are going to use PetClinic, available on GitHub. It is a sample spring application with JUnit test cases already written for it.
Note
A sample Spring-based application https://github.com/spring-projects/spring-petclinic .
The PetClinic sample application can be used to build simple and robust database-oriented applications to demonstrate the use of Spring's core functionality. It is accessible via web browser:
A few use cases:
- Add a new pet owner, a new pet, and information pertaining to a visit to the pet's visitation history to the system
- Update the information pertaining to a pet and pet owner
- View a list of veterinarians and their specialties, a pet owner, a pet, and pet's visitation history
