How do you set the viewport, width, with phantomjs with play 2 framework - scala

Question

I have been struggling with this for a while, I can't find a way to instruct phantomjs about the viewport. I am using play 2.2 (code is based on: Set Accept-Language on PhantomJSDriver in a Play Framework Specification )
package selenium
import org.specs2.mutable.Around
import org.specs2.specification.Scope
import play.api.test.{TestServer, TestBrowser, FakeApplication}
import org.openqa.selenium.remote.DesiredCapabilities
import org.specs2.execute.{Result, AsResult}
import play.api.test.Helpers._
import scala.Some
import org.openqa.selenium.phantomjs.PhantomJSDriver
import org.openqa.selenium.NoSuchElementException
import java.io.File
import java.io.PrintWriter
import java.util.concurrent.TimeUnit
import collection.JavaConversions._
abstract class WithPhantomJS(val additionalOptions: Map[String, String] = Map()) extends Around with Scope {
implicit def app = FakeApplication()
implicit def port = play.api.test.Helpers.testServerPort
// for phantomjs
lazy val browser: TestBrowser = {
val defaultCapabilities = DesiredCapabilities.phantomjs
print(defaultCapabilities.toString)
val additionalCapabilities = new DesiredCapabilities(mapAsJavaMap(additionalOptions))
val capabilities = new DesiredCapabilities(defaultCapabilities, additionalCapabilities)
val driver = new PhantomJSDriver(capabilities)
val br = TestBrowser(driver, Some("http://localhost:" + port))
br.webDriver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS)
br
}
override def around[T: AsResult](body: => T):Result = {
try {
running(TestServer(port, FakeApplication()))(AsResult.effectively(body))
} catch {
case e: Exception => {
val fn: String = "/tmp/test_" + e.getClass.getCanonicalName;
browser.takeScreenShot(fn + ".png")
val out = new PrintWriter(new File(fn + ".html"), "UTF-8");
try {
out.print(browser.pageSource())
} finally {
out.close
}
throw e;
}
} finally {
browser.quit()
}
}
}
and the actual test looks like this:
class ChangeName extends Specification {
"User" should {
"be able to change his name in account settings" in new WithPhantomJS() {
// ... this throws
I'd like the exception handler to render the site, which works, however, i can see the with matching a mobile device (narrow).
How can I change the width?

This seems to work:
import org.openqa.selenium.Dimension
...
browser.webDriver.manage().window().setSize(new Dimension(1280, 800))
