I won’t use Wiremock with Spring Boot anymore for smaller simpler services.

Spring and Spring boot is my day to day tech as part of my present organisation, along with it unit/ integration testing is something which we all do for maintaining the code quality and code coverage.

Recently I was just writing few unit tests in my code, used @SpringBootTest for the tests.

The code was nothing more than consuming the downstream endpoints using the RestTemplate class - very straightforward. Generally teams(including mine) would make use of a mock downstream server(wiremock or something custom) to satisfy the availability of the mock endpoints during the unit/ integration test run.

So I came up with an idea of creating an endpoint corresponding to the downstream in the test package itself by creating a @RestController class in the test package.

I would rather name the tests here as Implementation tests like a boundary between integration and unit tests, a combination of both.

Code & Config

The example for this POC is here.

It is very easy codebase to explore with & you will easily be able to get the idea about it.
