Class DropwizardClientRule

java.lang.Object

org.junit.rules.ExternalResource

io.dropwizard.testing.junit.DropwizardClientRule

All Implemented Interfaces:

org.junit.rules.TestRule

public class DropwizardClientRule
extends org.junit.rules.ExternalResource

Test your HTTP client code by writing a JAX-RS test double class and let this rule start and stop a Dropwizard application containing your doubles.

Example:

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

     @ClassRule
    public static DropwizardClientRule dropwizard = new DropwizardClientRule(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 DropwizardClientRule 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.
