title: How do I use the normal controller test assertions in Minitest Spec DSL
body: <p>I usually write my specs in RSpec but I use Minitest too.
  Recently I learnt that there is a minitest dsl that could read like RSpec. They call it Minitest::Spec. I have checked it out and I think I like it. The <code>gem 'minitest-rails'</code> makes the setup configuration easy. There is however one limitation I have faced and that is in the integration specs. What is the equivalent for assertions like <code>assert_response</code>, <code>assert_no_difference</code>, and <code>assert_template</code>?</p>
