CodeShip rspec controller test failed
<p>I'm trying to make make my app buildable via CodeShip.</p>

<p>It builds nicely when using Travis CI (except some integration tests, but this is an another story) and, of course, on my local machine. However, the same code is failed to be tested just in one certain place if CodeShipping. I wouldn't be suprised if the fail was about feature testing, but it fails within a controller spec!</p>

<p><strong>CodeShip error:</strong></p>

<pre><code>Failures:

1) ParrotsController GET #index with filters returns by id
Failure/Error: expect(json.count).to eq 1

  expected: 1
       got: 0

  (compared using ==)

# ./spec/controllers/parrots_controller_spec.rb:117:in `block (4 levels) in &lt;top (required)&gt;'
</code></pre>

<p>It's so weird, because there are nearly the same tests below and upper that one. I wouldn't be surprised if the problem was about javascript and features, but it's just a controller test! I'm really frustrated.</p>
