why didnt the second test fail?

rspec_greeter_spec.rb

require "vertx"
require "java"
include Vertx

Vertx.deploy_verticle('RSpecGreeter.java') {}

describe "RSpec Greeter" do
  it "should say 'Hello RSpec!' when it recieves the greet() message" do
    vessel = ""
    Vertx::EventBus.send("rspecgreeter.greet", "greet") do |message|
      vessel = message.body
    end
    1.should == 3
    sleep(3)
    puts vessel
    vessel.should == "Hello RSpec!"
  end
end
