Question

Using Play 2.1-RC1 I can’t write simple test.

Here’s the action code:

def echoTestTagFromXml = Action(parse.xml) { request =>
    (request.body \ "test" headOption).map(_.text).map { test =>
        Ok(views.xml.testTag(test))
    }.getOrElse {
      BadRequest("Missing parameter [name]")
    }
}

Here’s testing code:

"Test Tag Xml Echo" in {
    running(FakeApplication()) {
      val req = new FakeRequest(POST, controllers.routes.SimpleResultsController.echoTestTagFromXml().url, FakeHeaders(), Xml("<test>gg</test>"))        
      val result = controllers.SimpleResultsController.echoTestTagFromXml()(req)
      status(result) must equalTo(OK)
    }
}

Test gives the error:

[error]  found   : play.api.libs.iteratee.Iteratee[Array[Byte],play.api.mvc.Result]
[error]  required: play.api.mvc.Result

From Google I know problem is in BodyParser. But I have no idea(after API investigation) how to make the code working.

The following modified testing code should work, but I think there is a bug at the moment when trying to pass a body into a FakeRequest, somewhat a hangover with the Functional tests now deprecated ‘routeAndCall’ function. The body is always empty.

"Test Tag Xml Echo" in {
  running(FakeApplication()) {
    val req = FakeRequest(POST, controllers.routes.SimpleResultsController.echoTestTagFromXml().url, FakeHeaders(), Xml("<test>gg</test>"))
      .withHeaders(CONTENT_TYPE -> "text/xml")
    val result = await(controllers.SimpleResultsController.echoTestTagFromXml()(req).run)
    contentAsString(result) must equalTo("gg")
    status(result) must equalTo(OK)
  }
}

I have a similar issue with passing Json into the body, but tried to get this working for your body parser (note the differences). Also, please set the content-type header.

You can however use the ‘route’ function instead:

"Test Tag Xml Echo Route" in {
  running(FakeApplication()) {
    val result = route(FakeRequest(POST, "/SimpleResultsController").withHeaders(CONTENT_TYPE -> "text/xml"), Xml("<test>gg</test>")).get
    contentAsString(result) must equalTo("gg")
    status(result) must equalTo(OK)
  }
}

This seems to work for me and you should be able to copy/paste this solution.

If you don’t want to repeat your route as a string then you can use the reverse routes as you did before: controllers.routes.SimpleResultsController.echoTestTagFromXml().url
