Read Private Type using Visual Studio Unit Testing in C#

small things can make a different

I want to read my class  private values to verify the unit testing using MS unit test.

Here is the sample code

Created the sample class named NumberChecker, it contains two private property and public method.
The method going to check, the passed number is greater than zero or not. based on that it's going to pass a different message back the client.

namespace PrivateTypeDemo
{
    public class NumberChecker
    {
        private const string Validmessage = "The Number is Greater than Zero";
        private const string DefaultMessage = "The Number is Zero or Less than Zero";
        public string ValidateNumber(int number)
        {
            return number > 0 ? Validmessage : DefaultMessage;
        }
    }
}

Here is the console application which consumes the library

namespace PrivateTypeDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            var numcheck = new NumberChecker();
            Console.WriteLine("Please Enter your Number");
            var  number = Convert.ToInt32(Console.ReadLine());
            var result = numcheck.ValidateNumber(number);
            Console.WriteLine(result);
 
 
        }
    }
}

Unit Test for the NumberCheck class

 [TestClass]
    public class NumberCheckerTest
    {
        [TestMethod]
        public void ValidateNumberTest()
        {
            var target = new NumberChecker();
            const int number = 15;
            var privateType = new PrivateType(target.GetType());
            var expected = privateType.GetStaticFieldOrProperty("Validmessage");
            string actual = target.ValidateNumber(number);
            Assert.AreEqual(expected, actual);
        }
        [TestMethod]
        public void ValidateNumber2Test()
        {
            var target = new NumberChecker();
            const int number = -5;
            var privateType = new PrivateType(target.GetType());
            var expected = privateType.GetStaticFieldOrProperty("DefaultMessage");
            string actual = target.ValidateNumber(number);
            Assert.AreEqual(expected, actual);
        }
        [TestMethod]
        public void NumberCheckerConstructorTest()
        {
            var target = new NumberChecker();
            Assert.IsNotNull(target);
        }
    }
The below lines does the magic of accessing the private type of the classes.This class is shipped part of the 
Microsoft.VisualStudio.TestTools.UnitTesting Assembly  which support this functionality in unit Testing

var privateType = new PrivateType(target.GetType());
var expected = privateType.GetStaticFieldOrProperty("DefaultMessage");

Here i am reading the value of DefaultMessage through the GetStaticFieldOrProperty Method in the PrivateType class

Enable Wifi without the Wireless Router for Home Usage

Recently I bought a Samsung mobile phone Y Series. To activate the Samsung app store and Google play store, it's asking me to connect via  WiFi . But i don't have a WiFi router with me. but i have 10 Mbps Airtel Broadband Connection

Now i have two options

• I have to activate Air tel 3 G in my mobile to access all the Samsung apps
• I need to buy the WiFi Router , so i could use my existing broad band connection

I don't want to spend extra money to activate 3G also WiFi router is extra overhead for me

I found this useful software for Windows 7, it will act as Virtual WiFi Router

Download the WiFi Router from here Download

 You can create a WiFi hotspot for WiFi Reverse Tethering for wifi supported mobiles and other wifi enabled computer to create a network and to share internet. Convert your PC into a WiFi hot spot for free.

Follow this instructions to configure it for the first time

Read Event Log Information using LINQ PAD

Anyone tried the LINQ PAD. I found this is very useful to execute for query any short of information from different sources like database, xml, event logs, iis logs with the minimal code

In this blog, i am going to show a example, how we could pull the summary of the events using the LINQ PAD

Link to download LINQ PAD http://www.linqpad.net/

LINQPad is a free software utility for Microsoft .NET to interactively query SQL databases and other data sources such as OData or WCF Data Services using LINQ. LINQPad supports the following LINQ dialects:

• LINQ to Objects
• LINQ to SQL
• Entity Framework
• LINQ to XML

It also supports writing queries in SQL as well.

Download and install the LINQ PAD. Open the LINQ PAD and select a new query and select the language as C# Program

Code

void Main()
{
var serverList = new List
  {
  //List of Servers Name
  };
var eventCollection = new Dictionary();

int count = 0;
foreach (var list in serverList)
{
var eventLog = new EventLog(EVENTLOGNAME, list, SOURCENAME);
        foreach (EventLogEntry logEntry in eventLog.Entries)
        {
if (logEntry.TimeGenerated  >=  DateTime.Today)
{
if (eventCollection.ContainsKey(logEntry.InstanceId))
{
eventCollection[logEntry.InstanceId]++;
}
else
{
eventCollection.Add(logEntry.InstanceId, 1);
}
}

        }
Console.WriteLine("Summary of Server " + list);
foreach (var logs in eventCollection)
{
Console.WriteLine(logs.Key + "  " + logs.Value);
}
eventCollection.Clear();
}

}

// Define other methods and classes here


Sample Output

Summary of the Server "ServerName1"
Event ID   Number Of Times
100            7
106            15

Summary of the Server "ServerName2"
Event ID   Number Of Times
100            70
106            8

One Way Contract in WCF

In this post, i am going to explain the benefit of the One way contract. I have a page which collect the feedback from the customer. it internally calls web service and send the feed back information to the DB via Wcf service

Created the simple Asp.NET web application which accept the feedback from the users

when the user enter the feedback and click the submit button it's going to call the FeedBackService and the service is not going to return back anything

For demo purpose, in WCF service side, i put thread to sleep for 5 seconds

[ServiceContract]
    public interface IService1
    {
 
        [OperationContract]
        void SendFeedBack(string Name, string Message);
 
       
 
    }

 public class FeedBackService : IService1
    {
        public void SendFeedBack(string Name, String Message)
        {
            Thread.Sleep(5000);
        }
 
        
    }

Let's look at the response time

Http Watch report for the response time

Before

Response time is 5.2 seconds

Adding the OneWay is true in  the service side and updating the proxy class from the client side

Server Side

 [ServiceContract]
    public interface IService1
    {
 
        [OperationContract(IsOneWay=true)]
        void SendFeedBack(string Name, string Message);
 
       
 
    }

Client Side

The following piece of code added part of the proxy

 [System.ServiceModel.OperationContractAttribute(IsOneWay=true, Action="http://tempuri.org/IService1/SendFeedBack")]
        void SendFeedBack(string Name, string Message);

After

The response time is comes down to 0.2 seconds

MSDN Description on Oneway call

There are cases when an operation has no returned values and the client does not care about the success or failure of the invocation. To support this sort of fire-and-forget invocation, Windows Communication Foundation offers one-way operations. After the client issues the call, Windows Communication Foundation generates a request message, but no correlated reply message will ever return to the client. As a result, one-way operations can't return values, and any exception thrown on the service side will not make its way to the client. One-way calls do not equate to asynchronous calls. When one-way calls reach the service, they may not be dispatched all at once and may be queued up on the service side to be dispatched one at a time, all according to the service configured concurrency mode behavior and session mode. How many messages (whether one-way or request-reply) the service is willing to queue up is a product of the configured channel and the reliability mode. If the number of queued messages has exceeded the queue's capacity, then the client will block, even when issuing a one-way call. However, once the call is queued, the client is unblocked and can continue executing while the service processes the operation in the background. This usually gives the appearance of asynchronous calls.

Enhanced Project Template in MVC4

Project Template is gives us the predefined, customized and reusable components. So It accelerates the development process  instead of starting the project from scratch.

Install the ASP.NET MVC 4 from the following Location MVC4 Setup

MVC 4 Enables list of following built in Template.

• Internet Application
• Intranet Application
• Mobile Application
• Web API
• Basic Template 
• Empty Template

MVC 4 Built In Templates

Go to Visual studio 2010 click File -> New Project and Select ASP.NET MVC 4 and click OK. this will popup another window,

This will list out Project Template and the option for the View Engine and whether to include the unit project or not



Internet Application

This templates help us to create a web application using asp.net MVC 4

For the first demo i am going to select the Internet Application,  if you notice the bottom of the visual studio while loading the first application in MVC 4, it will load all the dependent packages through Nuget. This is one of the new functionality which is added part of the MVC 4

How do i check the list of package installed part of my application?


In Solution Explorer, select your project and open the Package.Config File, This file contains the list of the Nuget Package used in this project.

This is my package.config file

 
 


I selected the internet application and the View Engine as Razor and i didn't check in the Unit Test Project
and click OK, it creates My Project with the list of predefined files. To run the application i hit Ctrl +F5

It loads my first application

In addition to cosmetic improvements, there’s improved functionality in the new template. The template employs a technique called adaptive rendering to look good in both desktop browsers and mobile browsers without any customization.

Intranet Application


This template look similar to the internet application, It uses the windows authentication instead of the forms authentication which is used by the Internet Application

Mobile Template


This template used to develop the project specific to the mobile and tablets browsers

This template contains the same application structure as the Internet Application template (and the controller code is virtually identical), but it's styled using jQuery Mobile to look good and behave well on touch-based mobile devices. To learn more about how to structure and style mobile UI, see the jQuery Mobile project website.
