title: coveralls.io and error handling in Golang
body: <p>I wrote a <a href="https://github.com/ahmdrz/goinsta" rel="nofollow">library for Instagram API</a> and tell coveralls.io to check my repository</p>
  
  <p>but coveralls.io tell me that all of the error handlers in my source code isn't Good. <a href="https://coveralls.io/builds/8405457/source?filename=request.go" rel="nofollow">see this</a></p>
  
  <p>How can I handle errors perfectly and coveralls.io say it's good :smile:</p>
