title: C# Unit testing - assert Json from Http response
body: <p>I am creating web api for a songsDB and I am trying to test API GET
      methods which return a Json string of songs in a list. The get method in
      question uses a linq queries and returns the songs as expected but am
      unable to write a unit test for this method and many like it with a
      concern for code coverage also. The app is hosted on azure and the data
      is being retrieved from an sql db instance in azure.
      The method displays the 5 cheapest albums in the db in ascending order.
      Any help is greatly appreciated.</p>
  
  <pre><code>//API GET Method
  [HttpGet("leastExpensive")]
  [ProducesResponseType(404)]
  [ProducesResponseType(200)]
  public ActionResult&lt;Tunes&gt; GetCheapestAlbums()
  {
      var price = _context.Songs
          .OrderBy(p =&gt; p.Price)
          .Select(g =&gt; new
      {
          g.ChartPosition,
          g.Artist,
          g.Genre,
          g.Price
      }).Take(5)
      .ToList();
      if (price == null)
      {
          return NotFound();
      }
      else
      {
          return Ok(price);
      }
  }
  </code></pre>
  
  <p>//Json response</p>
  
  <pre><code>[{
      "chartPosition":29,"artist":"ABBA","genre":"Pop","price":4.39
  },{
      "chartPosition":60,"artist":"Amy Whinehouse","genre":"Pop","price":5.05
  },{
      "chartPosition":10,"artist":"BB King","genre":"Blues","price":5.5
  },{
      "chartPosition":15,"artist":"Kenny Rogers","genre":"Country","price":5.92
  },{
      "chartPosition":17,"artist":"Pearl Jam","genre":"Rock","price":6.29
  }]
  </code></pre>
  
  <p>I am looking to assert the Json string as equal</p>
