How can I use WireMock for advanced API mocking?

WireMock allows you to create complex API mocks with features like stateful behavior, request matching, and response templating. What specific advanced features are you interested in?

Can you explain how to set up stateful behavior?

Sure! Stateful behavior in WireMock can be achieved using scenarios. You define a scenario and specify different responses based on the state. Would you like a code example?

Yes, please provide a code example for that.

Here's a simple example:

stubFor(get(urlEqualTo("/api/resource"))
    .inScenario("My Scenario")
    .whenScenarioStateIs("Started")
    .willReturn(aResponse().withBody("Initial Response")));

stubFor(get(urlEqualTo("/api/resource"))
    .inScenario("My Scenario")
    .whenScenarioStateIs("Initial Response")
    .willReturn(aResponse().withBody("Next Response")));

This sets up a scenario that changes state based on the responses.

That makes sense! How do I reset the scenario state?

You can reset the scenario state by using the resetScenarios method in your WireMock server setup. This will clear all scenario states.
