title: Check response header's value in Postman tests
body: <p>I would like to check the value from a concrete response header ("Location") as Test Results in Postman.
  In the Postman's documentation I found examples of how to check the existance of headers with</p>
  
  <pre><code>pm.test("Content-Type is present", function () {
     pm.response.to.have.header("Content-Type");
  });
  </code></pre>
  
  <p>But what I'm looking for is something like</p>
  
  <pre><code>pm.test("Location value is correct", function () {
     CODE HERE THAT CHECKS "Location" HEADER EQUALS TO SOMETHING;
  });
  </code></pre>
