title: Creating multiple cookies with single frisby.js test file
body: <p>How can I create multiple cookies with a single file?
  All I have to just do is, merge these two file into one single file, to test it for both - valid and invalid cookie.
  How can I achieve this?</p>
  
  <p>First file:</p>
  
  <p>valid cookie
  valid_spec.js</p>
  
  <pre><code> var frisby = require('./lib/frisby');
   // Global setup for all tests
   frisby.globalSetup({
   request: {
   headers:{'Accept': 'application/json,  application/x-httpd-php', 'Cookie': 'authenticationToken=5363; activationID=1'}
   },
    timeout: (30 * 1000)
  });
  
  
  /**
  * Tests -&gt; GET
  */
  frisby.create(' ')
  .get('http://xyz/auto?limit=0')
  .expectStatus(200)
  .expectHeaderContains('content-type', 'application/json')
  .expectJSON('status',{
   message: "SUCCESS",
   code: 1
   })
  .toss(); 
  </code></pre>
  
  <p>Second file:</p>
  
  <p>INVALID cookie
  invalid_spec.js</p>
  
  <pre><code>var frisby = require('./lib/frisby');
  
  // Global setup for all tests
   frisby.globalSetup({
   request: {
   headers:{'Accept': 'application/json,  application/x-httpd-php', 'Cookie': 'authenticationToken=5363; activationID=11123fgf'}
   },
   timeout: (30 * 1000)
   });
  
  
  /**
  * Tests -&gt; GET
  */
  frisby.create(' ')
  .get('http://xyz/auto?limit=0')
  .expectStatus(200)
  .expectHeaderContains('content-type', 'application/json')
  .expectJSON('status',{
  message: "DATABASE_ERROR",
  code: 2
   })
   .toss(); 
  </code></pre>
