Integrating Wiremock with scalatestplus.play

[Abhishek Jain]

Hi,

We are trying to upgrade our code to Play 2.6

But are facing an issue when try to use wiremock. 

I am not sure if it's an issue with 

"org.scalatestplus.play" %% "scalatestplus-play" % "3.0.0-RC1" % IntegrationTest 

or 

"com.github.tomakehurst" % "wiremock" % "2.6.0" % IntegrationTest

Below are my dependencies in  build.sbt.

```

libraryDependencies ++= Seq(

  "com.github.tomakehurst" % "wiremock" % "2.6.0" % IntegrationTest,

  "org.mockito" % "mockito-core" % "1.9.0" % "test",

  "org.jsoup" % "jsoup" % "1.10.2" % "test",

  "org.scalactic" %% "scalactic" % "3.0.1" % "test, it",

  "org.scalatest" %% "scalatest" % "3.0.1" % "test, it",

  "org.scalatestplus.play" %% "scalatestplus-play" % "3.0.0-RC1" % IntegrationTest,

  guice

)

```

and a sample wire mock test

```

import akka.actor.ActorSystem

import akka.http.scaladsl.Http

import akka.http.scaladsl.model.{HttpMethods, HttpRequest}

import akka.stream.ActorMaterializer

import org.scalatest.{BeforeAndAfterEach, FlatSpec, Matchers}

import com.github.tomakehurst.wiremock.WireMockServer

import com.github.tomakehurst.wiremock.client.WireMock

import com.github.tomakehurst.wiremock.client.WireMock._

import com.github.tomakehurst.wiremock.core.WireMockConfiguration._

import org.scalatest.concurrent.ScalaFutures

class ScalaTest extends FlatSpec with Matchers with BeforeAndAfterEach with ScalaFutures {

  implicit val system = ActorSystem("my-system")

  implicit val materializer = ActorMaterializer()

  val Port = 8080

  val Host = "localhost"

  val wireMockServer = new WireMockServer(wireMockConfig().port(Port))

  override def beforeEach {

    wireMockServer.start()

    WireMock.configureFor(Host, Port)

  }

  override def afterEach {

    wireMockServer.stop()

  }

  "WireMock" should "stub get request" in {

    val path = "/my/resource"

    stubFor(get(urlEqualTo(path))

      .willReturn(

        aResponse()

          .withStatus(200)))

    val request = Http().singleRequest(

      HttpRequest(

        HttpMethods.GET,

        uri = s"http://$Host:$Port$path")

    )

    whenReady(request) { response =>

      response.status.intValue() shouldBe 200

    }

  }

}

```

Now when I try to run my test. I get the below error.

```

 needed class was not found. This could be due to an error in your runpath. Missing class: org/eclipse/jetty/http/HttpGenerator$CachedHttpField

```

Strangely when I remove   

"org.scalatestplus.play" %% "scalatestplus-play" % "3.0.0-RC1" % IntegrationTest,

Everything works fine. But I cannot use GuiceOneServerPerSuite.

Please advice me if i have done something wrong or there is a bug.

Hi,

In case of someone is stumbling over this fairly old message and is interested in an answer:

Some Selenium drivers in the transitive dependencies of ScalaTest and/or ScalaTest plus Play comes with a newer version of Jetty which is not compatible with Wiremock. If fixed the issue by overriding jetty versions:

val jettyVersion = "9.2.13.v20150730"
  ...
dependencyOverrides ++= Set(
    "org.eclipse.jetty" % "jetty-server" % jettyVersion,
    "org.eclipse.jetty" % "jetty-servlet" % jettyVersion,
    "org.eclipse.jetty" % "jetty-security" % jettyVersion,
    "org.eclipse.jetty" % "jetty-servlets" % jettyVersion,
    "org.eclipse.jetty" % "jetty-continuation" % jettyVersion,
    "org.eclipse.jetty" % "jetty-webapp" % jettyVersion,
    "org.eclipse.jetty" % "jetty-xml" % jettyVersion,
    "org.eclipse.jetty" % "jetty-client" % jettyVersion,
    "org.eclipse.jetty" % "jetty-http" % jettyVersion,
    "org.eclipse.jetty" % "jetty-io" % jettyVersion,
    "org.eclipse.jetty" % "jetty-util" % jettyVersion,
    "org.eclipse.jetty.websocket" % "websocket-api" % jettyVersion,
    "org.eclipse.jetty.websocket" % "websocket-common" % jettyVersion,
    "org.eclipse.jetty.websocket" % "websocket-client" % jettyVersion
    
  )

Hope this helps.

Best,

 Matthias
