Cannot run unit test on scala playframework

Question

I am new to playframework. I am trying to run a unit test. This is my OneTimeTestSuite file. Here is the code in it.

package com.sentrana.mmcore.test

import org.scalatest.{ DoNotDiscover, Suites }
import org.scalatestplus.play.OneAppPerSuite
import play.api.test.FakeApplication
import com.sentrana.mmcore.controllers.MetaDataSpec
import com.sentrana.Global

class OneTimeTestSuite extends Suites(
  new MetaDataSpec
) with OneAppPerSuite {
  implicit override lazy val app: FakeApplication =
    FakeApplication(withGlobal = Some(Global), additionalConfiguration = Map(
      "ConfigSubFolderLocation" -> "/conf/"
    ))
}

Here is the code in MeteDataSpec file.

package com.sentrana.mmcore.controllers

import play.api.Play
import play.api.Play.current
import org.joda.time.DateTime
import org.scalatestplus.play.{ PlaySpec, ConfiguredApp }
import play.api.libs.json.{ JsValue, Json }
import play.api.mvc.Cookie
import play.api.test.FakeRequest
import play.api.test.Helpers._
import org.json4s.native.Serialization._
import play.api.test._

class MetaDataSpec extends PlaySpec with ConfiguredApp {
  "GetCustomers" should {
    "get all the customers" in {
      val response = route(FakeRequest(GET, "/api/shop/v0.1/metadata/customers")).get
    }
  }
}

I am using scalatestplus.

This is the command I am running for testing.

test-only com.sentrana.mmcore.test.OneTimeTestSuite

This is error I am getting

java.lang.NoSuchMethodError: play.core.Router$HandlerDef.<init>(Ljava/lang/Object;Ljava/lang/String;Ljava/lang/String;Lscala/collection/Seq;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)V

I hope I have made my question clear. If there is any confusion, please ask. Thanks in advance.

Answer 1

Your project is marked as scala 2.11 but you're using json4s at 2.10. Scala does not have binary compatibility between major versions.

Change your dependency to something like

"org.json4s" %% "json4s-mongo" % "3.2.10",
"org.json4s" %% "json4s-ext" % "3.2.10",

The %% automatically adds the scala version suffix to the artifact name, which is the convention for scala
