def done
  EM.cancel_timer(@timeout)
  EM.stop
end

#timeout_interval ⇒ Object

#wait ⇒ Object Also known as: wait!

wait indicates that the spec is not expected to be completed when the block is finished running. A call to done is required when using wait.

# setup my spec to use EM::MiniTest::Spec
describe MyClass do
  include EM::MiniTest::Spec

  # The call to defer will return immediately, so the spec code
  # needs to keep running until callback is called.
  it "does some async things" do
    defer_me = lambda do
      # some async stuff
    end

    callback = lambda do
      done!
    end

    EM.defer defer_me, callback

    wait!
  end

def wait
  @wait = true
end

#wait_for ⇒ Object

A helper method for the use case of waiting for some operation to complete that is not necessarily under the control of the spec code.

# These are exactly equivalent
it "waits with the helper" do
  wait_for do
    assert true
  end
end

it "waits manually" do
  EM.next_tick do
    assert true
    done!
  end

  wait!
