Trait that provides a new Application instance for each test.

This TestSuiteMixin trait's overridden withFixture method creates a new Application before each test and ensures it is cleaned up after the test has completed. You can access the Application from your tests as method app (which is marked implicit).

By default, this trait creates a new Application for each test using default parameter values, which is returned by the newAppForTest method defined in this trait. If your tests need a Application with non-default parameters, override newAppForTest to return it.

Here's an example that demonstrates some of the services provided by this trait:

package org.scalatestplus.play.examples.oneapppertest

import org.scalatest._
import org.scalatestplus.play._
import org.scalatestplus.play.guice.GuiceOneAppPerTest
import play.api.{Play, Application}
import play.api.inject.guice._

class ExampleSpec extends PlaySpec with GuiceOneAppPerTest {

  // Override newAppForTest if you need an Application with other than non-default parameters.
  implicit override def newAppForTest(testData: TestData): Application =
    new GuiceApplicationBuilder().configure(Map("ehcacheplugin" -> "disabled")).build()

  "The OneAppPerTest trait" must {
    "provide an Application" in {
      app.configuration.getOptional[String]("ehcacheplugin") mustBe Some("disabled")
    }
    "make the Application available implicitly" in {
      def getConfig(key: String)(implicit app: Application) = app.configuration.getOptional[String](key)
      getConfig("ehcacheplugin") mustBe Some("disabled")
    }
    "start the Application" in {
      Play.maybeApplication mustBe Some(app)
    }
  }
}
