Object reference not set to an instance of an object.

[harvinders]

I setup my project just like in the example but keep on getting this exception.

I am using VS 2013, Win 8.1 64bit

System.NullReferenceException was unhandled by user code
  HResult=-2147467261

In order to get SpecResults to work across the board, what I did was create a hook class that enherits > ReportingStepDefinitions

Create a static method with an attribute : BeforeTestRun Inside the method you would choose which report structure you want (I use JSON): Reporters.Add(new JsonReporter());

You will need to import > using SpecResults; using SpecResults.Json;

Then, create another static method within the hook class with either attributes: AfterScenario/AfterFeature

For AfterScenario: [AfterScenario] public static void AfterScenarioRun() { Reporters.FinishedScenario += (sender, args) => { //Console.WriteLine(args.Reporter.WriteToString()); var serializedReport = JsonConvert.SerializeObject(args.Reporter); //Console.Write(String.Format("{0}", JsonConvert.DeserializeObject(serializedReport))); //Console.Write("\nEnd."); }; }

For AfterFeature: [AfterFeature] public static void AfterFeatureRun() { Reporters.FinishedFeature += (sender, args) => { //Console.WriteLine(args.Reporter.WriteToString()); var serializedReport = JsonConvert.SerializeObject(args.Reporter); Console.Write(String.Format("{0}", JsonConvert.DeserializeObject(serializedReport))); Console.Write("\nEnd."); }; }

Notice the difference of Reporter.FinishedFeature & Reporter.FinishedScenario

Hope this helps.
