Simple BDD API for testing asynchronous Ruby/EventMachine code
(c) 2008 Aman Gupta (tmm1)
The API is identical to Bacon, except that you must explicitly call 'done' after all the current behavior's assertions have been made:
require 'em/spec'
EM.describe EventMachine do
should 'have timers' do
start = Time.now
EM.add_timer(0.5){
(Time.now-start).should.be.close 0.5, 0.1
done
}
end
should 'have periodic timers' do
num = 0
start = Time.now
timer = EM.add_periodic_timer(0.5){
if (num += 1) == 2
(Time.now-start).should.be.close 1.0, 0.1
EM.__send__ :cancel_timer, timer
done
end
}
end
end
