Trait that helps you provide different fixtures to different tests: a Application, a TestServer, or one of the Selenium WebDriverss.

Trait MixedFixtures can be mixed into any fixture.Suite. For convenience it is mixed into MixedPlaySpec. In a fixture.Suite, tests can take a no-arg function. MixedFixtures provides several no-arg function classes (classes extending Function0) that can be used to provide different fixtures for different tests.

If a test needs a Application, use the App function, like this:

"provide an Application" in new App(fakeApp("ehcacheplugin" -> "disabled")) {
  app.configuration.getOptional[String]("ehcacheplugin") mustBe Some("disabled")
}

If a test needs an Application and running TestServer, use the Server function, like this:

"send 404 on a bad request" in new Server {
  import java.net._
  val url = new URL("http://localhost:" + port + "/boom")
  val con = url.openConnection().asInstanceOf[HttpURLConnection]
  try con.getResponseCode mustBe 404
  finally con.disconnect()
}

If a test needs an Application, running TestServer, and Selenium driver, use one of functions Chrome, Firefox, HtmlUnit, InternetExplorer, or Safari. If the chosen Selenium driver is unavailable on the host platform, the test will be automatically canceled. Here's an example that uses the Safari function:

"provide a web driver" in new Safari(fakeApp()) {
  go to ("http://localhost:" + port + "/testing")
  pageTitle mustBe "Test Page"
  click on find(name("b")).value
  eventually { pageTitle mustBe "scalatest" }
}
