Well, reading the documentation was not helpful but reading the jersey integration tests source code was.

In the JerseyTest instance you need to override the configureClient method and pass in the MultiPartFeature class.

@Override
protected void configureClient(ClientConfig config) {
    config.register(MultiPartFeature.class);
}

Working Code:

import static org.hamcrest.Matchers.is;

import javax.ws.rs.Consumes;
import javax.ws.rs.FormParam;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.Application;
import javax.ws.rs.core.Form;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import org.glassfish.jersey.client.ClientConfig;
import org.glassfish.jersey.media.multipart.FormDataBodyPart;
import org.glassfish.jersey.media.multipart.FormDataMultiPart;
import org.glassfish.jersey.media.multipart.MultiPartFeature;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.test.JerseyTest;
import org.junit.Test;

public class TestMultiPartTest extends JerseyTest {

    @Override
    protected Application configure() {
        ResourceConfig rc = new ResourceConfig(ServerSideResource.class);
        rc.register(MultiPartFeature.class);
        return rc;
    }

    @Override
    protected void configureClient(ClientConfig config) {
        config.register(MultiPartFeature.class);
    }

    @Path("test")
    public static class ServerSideResource {

        @POST
        @Path("/multipart")
        @Consumes(MediaType.MULTIPART_FORM_DATA)
        // @Produces(MediaType.APPLICATION_JSON)
        public Response file(FormDataMultiPart formParams) {
            System.out.println("found multipart resource");
            return Response.ok().build();
        }

        @POST
        @Path("/encoded")
        @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
        // @Produces(MediaType.APPLICATION_JSON)
        public Response file(@FormParam("field3") String field3) {
            System.out.println("found encoded resource");
            System.out.println("got form.field3 value: " + field3);
            return Response.ok().build();
        }

    }

    @Test
    public void testAnotherWay() {
        WebTarget target = target("test/encoded");
        final Form form = new Form();
        form.param("field3", "field3 value");
        System.out.println("testAnotherWay");
        Response response = target.request().post(Entity.form(form), Response.class);
        System.out.println(response);
    }

    @Test
    public void testPostMultiPartFile() {
        final WebTarget target = target().path("test/multipart");
        final FormDataMultiPart mp = new FormDataMultiPart();
        final FormDataBodyPart p = new FormDataBodyPart("field1", "CONTENT ONE");
        mp.bodyPart(p);
        final FormDataBodyPart p2 = new FormDataBodyPart("field2", "CONTENT TWO");
        mp.bodyPart(p2);

        System.out.println("field1: " + mp.getField("field1").getValue());
        System.out.println("field2: " + mp.getField("field2").getValue());
        System.out.println("making multipart request");
        final Response r = target.request().post(Entity.entity(mp, MediaType.MULTIPART_FORM_DATA), Response.class);
        System.out.println(r);
        assertThat("response is 200", r.getStatus(), is(200));
    }

    @Test
    public void testPostEncodedForm() {
        final WebTarget target = target().path("test/encoded");
        final Form form = new Form();
        form.param("field3", "field3 value");
        System.out.println("making encoded request");

        final Response r = target.request().post(Entity.form(form), Response.class);
        System.out.println(r);
        assertThat("response is 200", r.getStatus(), is(200));
    }

}
