Testing custom validators with rspec. Why do I get Proc?

Question

As the title suggest I am trying to test a custom validator with Rspec. I get an error and I don't understand why... If you can shed some light I would really appreciate it. Here we go:

Validator spec

require 'spec_helper'

describe GraphDateValidator do

  it "should not validate activity with empty start time" do
    expect { Graph.new( {start_time: ''}).valid? }.to eq(false)
  end
end

If I print Graph.new( {start_time: ''}).valid? it prints false

However when it goes through the spec it returns a Proc object:

expected: false
            got: #<Proc:0x007fe5853fdd48@/Users/MLP/...

Can anybody tell me why I am getting that proc object? Thank you!

By using {} in your expect, then you really aren't executing the expect method --- instead you're sending expect a block. So rename to

it "should not validate activity with empty start time" do
  expect( Graph.new( {start_time: ''}).valid? ).to eq(false)
end
