Spring Boot Java Base Project

This project is a base project with the following utilities:

• RESTFul controller
• Spring JPA with Postgres
• WebClient as HTTP client

Testing end to end

We set up an end-to-end testing using:

• SpringBootTests framework with a random port
• WireMock server as HTTP mock server
• RestAssured as HTTP client and assertion
• ObjectMapper as JSON normalizer and assertion

How end to end tests works

The following is what happens:

• Spring boot starts the project in a random port
• A WireMock server is started
• A Postgres database is started using tests containers
• By each test:
  • JSON mocks are injected in the WireMock server before each test run
  • A RESTFul call is made using RestAssured to the Spring Boot controller
  • An assert is performed against the status response code
  • The JSON response is extracted
  • The JSON response is normalized, alongside with its expected response
  • The actual and expected JSON are compared
  • JSON mocks are reset
