Recently I was conducting internal training on using WireMock for testing web applications — especially the backend. Here I would like to share how to start WireMock and use it in your tests.

What is WireMock?

WireMock is a flexible and powerful API mocking tool that allows developers and testers to simulate HTTP-based APIs. It provides a simple and intuitive interface for creating mock APIs, making it easier to test applications that depend on external services. With WireMock, you can create mock responses, simulate various scenarios, and validate the behaviour of your application under different conditions.
