Hello,

Can anyone please provide some guidance in how to go about writing test code coverage for Webservices API Calls to a 3rd party application.

Following is the code, that I am trying to get code coverage for:

 String datumapp = '{'
      + '"serial_number":"'+SerialNumber + '",'
      + '"model":"A20-R-500",'
      + '"reseller":"'+ SFDCResellerID +'",'
      + '"client":"' + SFDCClientID +'",'
      + '"package":"'+ PackageType +'",'
      + '"offsite":"'+ Offsite +'",'
      + '"data_center":"'+ DataCenter +'",'
      + '"status":"active"'
      + '}';
      
             
      Http httpProtocolInsertAppliance = new Http();       // Create HTTP request to send.
      HttpRequest requestapp = new HttpRequest(); // Set the endpoint URL.
      String endpointapp = 'https://rmc01.asdsdt.net/sfapi/appliance/';
      requestapp.setEndPoint(endpointapp);
      requestapp.setBody(datumapp);
      requestapp.setMethod('POST');
      requestapp.setHeader('X-API-KEY','abczyx');
      requestapp.setHeader('Content-length', String.valueOf(datumapp.length()));

      
      try
      {
      
      HttpResponse responseapp = httpProtocolInsertAppliance.send(requestapp);
      System.debug(responseapp.getBody()+'APPLIANCE INSERTION CHECK 1');
      System.debug(responseapp.getHeader('Location')+'APPLIANCE INSERTION CHECK 1');
     
      
      if(String.valueof(responseapp.getStatus())=='400')
      {
      
      throw new IntegrationException('Already exists');
      }
