What is WireMock for JUnit?

Can you explain what WireMock is and how it works with JUnit?

WireMock is a tool for mocking HTTP services. It allows you to simulate API responses in your tests, making it easier to test your application without relying on external services.

How do I set up WireMock in a JUnit test?

To set up WireMock in a JUnit test, you can use the @Rule annotation to create a WireMockServer instance. Here's a simple example:

import com.github.tomakehurst.wiremock.junit.WireMockRule;
import org.junit.Rule;
import org.junit.Test;

public class MyTest {
    @Rule
    public WireMockRule wireMockRule = new WireMockRule(8080);

    @Test
    public void testMyService() {
        // Your test code here
    }
}

What are some common use cases for WireMock?

Common use cases for WireMock include testing microservices, simulating third-party APIs, and creating reliable tests that don't depend on external systems.

Can WireMock be used for performance testing?

Yes, WireMock can be used for performance testing by simulating various load scenarios and measuring how your application responds under different conditions.
