title: Rspec expect(method) vs expect(method).to be_true
body: <p>I've just started diving into TDD with RSpec and Rails and I've found that if I'm testing a method that should come out to be true that the test will work if i use expect(method) instead of expect(method).to be_true.</p>
  
  <pre><code>it "is true" do
    expect(subject).to be_true
    #Works the same as...
    expect(subject)
  end
  </code></pre>
  
  <p>Is there any reason to not use the expect without .to, will it break the tests or not catch certain failures? Just wondering.</p>
