jHTTPMock

Very simple mock HTTP Server for Java built with Jetty and JUnit. Inspired by WireMock and Jadler.

Key features:

• fast onboarding
• fluent API
• latency and failure simulation
• minimal dependencies, small footprint
• supports multiple concurrent instances

On the contrary, there is no complex response modelling. Why not? I think the test cases should be as simple as possible and it should not be necessary to implement any complex logic.

Quick Example

The example is using JHttpMock as a JUnit rule.

public class BasicUseCase {
    @Rule
    public MockHttpServerRule mock = new MockHttpServerRule(new JettyMockHttpServer(8081));
    
    @Test
    public void test() {
        // define mock request behaviour
        
        mock
            .onRequest()
            .withUrlEqualTo("/ping")
            .thenRespond()
            .withCode(200)
            .withRandomDelay(Duration.ofMillis(30), Duration.ofMillis(50))
            .withBody("Hello!")
            .orRespondWithProbability(0.01)
            .withCode(503)
            .withFixedDelay(Duration.ofSeconds(5));
           
        // TODO: send HTTP request
        
        // verify mock server interactions
        
        mock
            .verifyThatRequest()
            .withUrlEqualTo("/ping")
            .wasReceivedOnce();
    }
}
