Package io.dropwizard.testing.junit5

Class DropwizardClientExtension

  • All Implemented Interfaces:
    DropwizardExtension
    public class DropwizardClientExtension
extends Object
implements DropwizardExtension
    Test your HTTP client code by writing a JAX-RS test double class and let this extension start and stop a Dropwizard application containing your doubles.

    Example: 

    
    @Path("/ping")
    public static class PingResource {
        @GET
        public String ping() {
            return "pong";
        }
    }

    public static DropwizardClientExtension dropwizard = new DropwizardClientExtension(new PingResource());

    @Test
    public void shouldPing() throws IOException {
        URL url = new URL(dropwizard.baseUri() + "/ping");
        String response = new BufferedReader(new InputStreamReader(url.openStream())).readLine();
        assertEquals("pong", response);
    }
    Of course, you'd use your http client, not URL.openStream().

    The DropwizardClientExtension takes care of:

    • Creating a simple default configuration.
    • Creating a simplistic application.
    • Adding a dummy health check to the application to suppress the startup warning.
    • Adding your resources to the application.
    • Choosing a free random port number.
    • Starting the application.
    • Stopping the application.
