Play 2.0 routes file for different configurations - configuration

Question

I have a Play 2.0 application with 3 different configurations (application.conf, test.conf and prod.conf)
Now I have a robots.txt file that should be delivered for only test.conf and for the rest environments it should give a 404 if someone tries to access it.
How can I configure my routes file to check if my application is using test.conf? Can I set some variable in test.conf that I can check in the routes file?
Something like this? (pseudo code)
#{if environment = "test"}
GET /robots.txt controllers.Assets.at(path="/public", file="robots.txt")
#{/if}
#{else}
GET /robots.txt controllers.Application.notFoundResult()
#{/else}

You can't add logic in the routes file.
I'd write a controller to serve the robots.txt file. Something like this:
In the routes file:
GET /robots.txt controllers.Application.robots
Then, in the controller, I'll test if I'm in a testing environment :
def robots = Action {
if (environment == "test") { // customize with your method
Redirect(routes.Assets.at("robots.txt"))
} else {
NotFound("")
}
}
I'm using Scala, but it can be easily translated to Java.
Edit - java sample
You can check if application is in one of three states: prod, dev or test, ie, simple method returning current state:
private static String getCurrentMode() {
if (play.Play.isTest()) return "test";
if (play.Play.isDev()) return "dev";
if (play.Play.isProd()) return "prod";
return "unknown";
}
you can use as:
play.Logger.debug("Current mode: "+ getCurrentMode());
of course in your case that's enough to use these condition directly:
public static Result robots() {
return (play.Play.isProd())
? notFound()
: ok("User-agent: *\nDisallow: /");
}
