Continue reading →: Testing HTTP Clients in Java with WireMock and Spring Boot
When a Spring Boot application calls an external REST API, integration tests face a familiar problem: the real service might be slow, unavailable, or simply impossible to control. WireMock solves this by running a local HTTP server that simulates the external API. You define stubs — rules that say „if…

Every application needs at least two environments: one where you can break things safely, and one where you absolutely cannot.
