title: inject controller from different file using same module
body: <p>I have two files </p>
  
  <p>test1.js </p>
  
  <pre><code>angular.module("test1",[]).controller("test1Ctrl",function(){
  // some code
  })
  </code></pre>
  
  <p>and</p>
  
  <p>test2.js</p>
  
  <pre><code>angular.module("test2",[]).controller("test2Ctrl",function(){
  //some code
  })
  </code></pre>
  
  <p>app.js </p>
  
  <pre><code>var app = angular.module("testApp",['test1','test2']);
  </code></pre>
  
  <p>My question is  how I can inject my both controller in app.js from <strong>test1.js</strong> and <strong>test2.js</strong> using same module  and not using module test1 and test2?</p>
