Screenplay - How to switch window in a multi-method Task? - serenity-bdd

Question

I am expanding from the Slideshare tutorial
On slide 164, we replace a bunch of code lines with:
connie.attemptsTo(
PlanAjourney.from("Waterloo").to("CanaryWharf").departingAt("09:00")
);
PlanAJourney class with only first method from should look something like:
public class PlanAjourney
{
public static PlanAjourney from(String departure)
{
return Task.where("{0} chooses #departure as a departure station",
Enter.theValue(departure).into(JourneyPlanner.DEPARTURE_STATION)
)
}
}
Now imagine this is not a single page application but a multiwindow appl. Imagine Connie needs to switch to another window to see JourneyPlanner.DEPARTURE_STATION.
Now I would like to get the actor to be able to get the current window handle. This would be something like:
import net.serenitybdd.screenplay.Actor;
import net.serenitybdd.screenplay.Task;
import net.serenitybdd.screenplay.abilities.BrowseTheWeb;
import net.serenitybdd.screenplay.actions.Click;
import net.serenitybdd.screenplay.actions.Enter;
import net.serenitybdd.screenplay.actions.Switch;
public class PlanAjourney
{
public static PlanAjourney from(String departure)
{
String currentWindowHandle = BrowseTheWeb.as(actor).getWindowHandle();
return Task.where("{0} chooses #departure as a departure station",
Click.on(HomePage.JOURNEY_PLANNER_LINK),
Switch.to(getNewWindowHandle(actor, currentWindowHandle)),
Enter.theValue(departure).into(JourneyPlanner.DEPARTURE_STATION)
)
}
private static String getNewWindowHandle(Actor actor, String currentWindowHandle)
{
for (String windowHandle : BrowseTheWeb.as(actor).getDriver().getWindowHandles())
{
if (!windowHandle.equals(currentWindowHandle))
{
return windowHandle;
}
}
return null;
}
}
But of course this doesn't compile because actor is not known.
How could I get the actor ? Or is there another way ?

Answer 1

Okay, I found a solution.
First we have a method in a StepDefinition calling:
public class PlanAJourneyStepDefinitions {
#When("^(.*) plans a journey from (.*) to (.*) departing at (.*)$")
public void plan_a_journey(String name, String departure,
String destination, String departureTime) throws Throwable {
Actor theUser = theActorCalled(name);
theUser.attemptsTo(
PlanAjourney.from(departure, theUser)
.to(destination)
.departingAt(departureTime)
);
}
}
We isolate the user to be able to pass him/her to the from method of PlanAjourney class.
Then it's easy to cope with the window switch:
public class PlanAjourney {
public static PlanAjourney from(String departure, Actor theUser) {
String currentHandle = BrowseTheWeb.as(theUser).getDriver().getWindowHandle();
return Task.where("{0} chooses #departure as a departure station",
Click.on(HomePage.JOURNEY_PLANNER_LINK),
Switch.toWindow(getNewWindowHandle(theUser, currentHandle)),
Enter.theValue(departure).into(JourneyPlanner.DEPARTURE_STATION)
);
}
private static String getNewWindowHandle(Actor actor, String currentWindowHandle){
for (String windowHandle : BrowseTheWeb.as(actor).getDriver().getWindowHandles()) {
if (!windowHandle.equals(currentWindowHandle)) {
return windowHandle;
}
}
return null;
}
}
But what I still don't get is how to make "from" method return an instance of PlanAJourney class. But that's a different question, so I will ask another one.
