I am not sure why I am getting one of my variables testlog is null. I am able to initialize and start the test but at the teardown method in my test class its not able to flush the reports and log it because testlog is null.. Any help would be great...

//Here is my ExtentReport class
```
public class ExtentReport
    {
        public static ExtentReports extent;
        public static ExtentTest testlog;
        public static bool testStarted = false;

        public static void StartReport()
        {
            //To obtain the current solution path/project path
            string path = System.Reflection.Assembly.GetCallingAssembly().CodeBase;
            string actualPath = path.Substring(0, path.LastIndexOf("bin"));
            string projectPath = new Uri(actualPath).LocalPath;

            string reportPath = projectPath + "Reports\\" + DateTime.Now.ToString("MM_dd_yyyy_HH_mm_ss") + ".html";

            ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter(reportPath);
            extent = new ExtentReports();
            extent.AttachReporter(htmlReporter);

            //Add QA system info to html report
            extent.AddSystemInfo("Tester", Environment.UserName);
            extent.AddSystemInfo("Environment", ConfigurationManager.AppSettings["TestEnvironment"]);
            extent.AddSystemInfo("MachineName", Environment.MachineName);
        }

        public static void StartExtentTest(string testsToStart)
        {
            testlog = extent.CreateTest(testsToStart);
            testlog.Log(Status.Pass, "Test steps start for test case " + TestContext.CurrentContext.Test.Name);
        }

         public static void LoggingTestStatusExtentReport()
         {
            try
            {
                var status = TestContext.CurrentContext.Result.Outcome.Status;
                var stacktrace = string.Empty + TestContext.CurrentContext.Result.StackTrace + string.Empty;
                var errorMessage = TestContext.CurrentContext.Result.Message;
                Status logstatus;
                switch (status)
                {
                    case TestStatus.Failed:
                        logstatus = Status.Fail;
                        testlog.Log(Status.Fail, "Test steps NOT Completed for Test case " + TestContext.CurrentContext.Test.Name + " ");
                        testlog.Log(Status.Fail, "Test ended with " + Status.Fail + " – " + errorMessage);
                        break;
                    case TestStatus.Skipped:
                        logstatus = Status.Skip;
                        testlog.Log(Status.Skip, "Test ended with " + Status.Skip);
                        break;
                    default:

                        testlog.Log(Status.Pass, "Test steps finished for test case " + TestContext.CurrentContext.Test.Name + " ");
                        testlog.Log(Status.Pass, "Test ended with " + Status.Pass);
                        break;
                }
            }
            catch (Exception e)
            {
                throw e;
            }

         }

        public void TestReportInitialize()
        {
            if (GetType().Name != typeof(BaseCrudHandler).Name)
            {
                if (testStarted == false)
                    ExtentReport.StartReport();
                testStarted = true;
            }
        }

        public void LogReport()
        {
            ExtentReport.LoggingTestStatusExtentReport();
            ExtentReport.extent.Flush();
        }


    }

//Here is my Test class 
public class ReportTest
{
    static ExtentReport report = new ExtentReport();

        [SetUp]
        public void SetUp()
        {
            //calling the method to start the test
            report.TestReportInitialize();
        }    

     [Test]
     public void GetTest()
  {
     Console.WriteLine("MyTest");
  }


        [TearDown]
        public void EndOfExecution()
        {
            report.LogReport();
        }


}

This is one of the most common problems we get asked, and it's also the one we are least equipped to answer, but you are most equipped to answer yourself.

Let me just explain what the error means: You have tried to use a variable, property, or a method return value but it contains null - which means that there is no instance of a class in the variable.
It's a bit like a pocket: you have a pocket in your shirt, which you use to hold a pen. If you reach into the pocket and find there isn't a pen there, you can't sign your name on a piece of paper - and you will get very funny looks if you try! The empty pocket is giving you a null value (no pen here!) so you can't do anything that you would normally do once you retrieved your pen. Why is it empty? That's the question - it may be that you forgot to pick up your pen when you left the house this morning, or possibly you left the pen in the pocket of yesterdays shirt when you took it off last night.

We can't tell, because we weren't there, and even more importantly, we can't even see your shirt, much less what is in the pocket!

Back to computers, and you have done the same thing, somehow - and we can't see your code, much less run it and find out what contains null when it shouldn't.
But you can - and Visual Studio will help you here. Run your program in the debugger and when it fails, VS will show you the line it found the problem on. You can then start looking at the various parts of it to see what value is null and start looking back through your code to find out why. So put a breakpoint at the beginning of the method containing the error line, and run your program from the start again. This time, VS will stop before the error, and let you examine what is going on by stepping through the code looking at your values.

But we can't do that - we don't have your code, we don't know how to use it if we did have it, we don't have your data. So try it - and see how much information you can find out!
