[Java EE] Implement a test for REST endpoint

1. We have the Bookendpoint.java:

 Packagecom.pluralsight.bookstore.rest;ImportCom.pluralsight.bookstore.model.Book;Importcom.pluralsight.bookstore.repository.BookRepository;ImportJavax.inject.Inject;Importjavax.validation.constraints.Min;Importjavax.ws.rs.*;ImportJavax.ws.rs.core.Context;ImportJavax.ws.rs.core.Response;ImportJavax.ws.rs.core.UriInfo;ImportJava.net.URI;Importjava.util.List;Import StaticJavax.ws.rs.core.MediaType.APPLICATION_JSON;//Api/books@Path ("/books") Public classBookendpoint {@InjectPrivatebookrepository bookrepository; @POST @Consumes (Application_json) PublicResponse createbook (book book, @Context uriinfo uriinfo) { Book=bookrepository.create (book); URI Createeduri=uriinfo.getbaseuribuilder (). Path (Book.getid (). toString ()). build (); returnresponse.created (Createeduri). build (); } @GET @Produces (Application_json) PublicResponse getbooks () {List<Book> books =Bookrepository.findall (); if(books.size () = = 0) {            returnresponse.nocontent (). build (); }        returnResponse.ok (books). build (); } @GET @Path ("/{id: \\d+}") @Produces (Application_json) PublicResponse GetBook (@PathParam ("id") @Min (1) (Long id) { book Book=bookrepository.find (ID); if(Book = =NULL) {            returnResponse.Status (Response.Status.NOT_FOUND). build (); }        returnResponse.ok (book). build (); }    //Api/books/count@GET @Path ("/count")     PublicResponse countbooks () {Long nbofbooks=Bookrepository.countall (); if(Nbofbooks = = 0) {            returnresponse.nocontent (). build (); }        returnResponse.ok (nbofbooks). build (); } @DELETE @Path ("/{id: \\d+}")     PublicResponse Deletebook (Long id) {bookrepository.delete (ID); returnresponse.nocontent (). build (); }}

2. Creating a test for the REST endpoint:

 Packagecom.pluralsight.bookstore.rest;ImportCom.pluralsight.bookstore.model.Book;ImportCom.pluralsight.bookstore.model.Language;Importcom.pluralsight.bookstore.repository.BookRepository;Importorg.jboss.arquillian.container.test.api.Deployment;ImportOrg.jboss.arquillian.junit.Arquillian;ImportOrg.jboss.arquillian.test.api.ArquillianResource;ImportOrg.jboss.shrinkwrap.api.ShrinkWrap;ImportOrg.jboss.shrinkwrap.api.asset.EmptyAsset;Importorg.jboss.shrinkwrap.api.spec.JavaArchive;ImportOrg.junit.After;Importorg.junit.Test;ImportOrg.junit.runner.RunWith;Importjavax.ws.rs.client.Entity;ImportJavax.ws.rs.client.WebTarget;ImportJavax.ws.rs.core.Response;Importjava.util.Date;Import StaticJavax.ws.rs.core.MediaType.APPLICATION_JSON;Import StaticJavax.ws.rs.core.Response.Status.CREATED;Import StaticJavax.ws.rs.core.Response.Status.NO_CONTENT;Import Staticorg.junit.assert.*; @RunWith (Arquillian.class) Public classBookendpointtest {//Testable tell Wildfly does not have this test,//cause we want to test from outside by using HTTP@Deployment (testable =false)     Public Staticjavaarchive createdeployment () {returnShrinkwrap.create (javaarchive.class). addclass (bookrepository.class). addclass (book.class). addclass (Language.class). addclass (Bookendpoint.class). addclass (jaxrsconfiguration.class).
