Playframework(18)RESTFul and Testing/Logging

Playframework(18)RESTFul and Testing/Logging

Finally, I decide to use Specs2 to test all my things. I may need to read more detail if I use this.

Testing the Controller
package controllers

import play.api.libs.json._
import play.api.mvc._
import models.Book

trait BookController {

  this: Controller =>

  def listBooks = Action {
    Ok(Json.toJson(Book.books))
  }

  def saveBook = Action(BodyParsers.parse.json) { request =>
    val b = request.body.validate[Book]
    b.fold(
      errors => {
        BadRequest(Json.obj("status" -> "OK", "message" -> JsError.toFlatJson(errors)))
      },
      book => {
        Book.addBook(book)
        Ok(Json.obj("status" -> "OK"))
      }
    )
  }

  def getBook(id:String) = Action {
    Book.getBook(id) match {
      case Some(b) => Ok(Json.toJson(b))
      case _ => Ok(Json.obj("status" -> "OK", "message" -> "Book Not Found!"))
    }
  }

  def deleteBook(id:String) = Action {
    Book.deleteBook(id)
    Ok(Json.obj("status" -> "OK"))
  }

  def updateBook(id:String) = Action(BodyParsers.parse.json){ request =>
    val b = request.body.validate[Book]
    b.fold(
      errors => {
        BadRequest(Json.obj("status" -> "OK", "message" -> JsError.toFlatJson(errors)))
      },
      book => {
        book.id = Some(id)
        Book.updateBook(book)
        Ok(Json.obj("status" -> "OK"))
      }
    )
  }

}

object BookController extends Controller with BookController

package controllers

import play.api.libs.json.JsValue
import play.api.mvc._
import play.api.test._
import scala.concurrent.Future

/**
* Created by carl on 9/9/15.
*/
class BookControllerSpec extends PlaySpecification with Results{

  class TestController() extends Controller with BookController

  "Book API#listBooks" should {
    "size should be 2" in {
      val controller = new TestController
      val result: Future[Result] = controller.listBooks.apply(FakeRequest())
      val bodyText: JsValue = contentAsJson(result)
      bodyText must not be null
    }
  }

}

This command will do the work
