How to Unit Test Private Methods in MS Test

Before we start to see, how a private method can be unit tested using the MS Test? Let us discuss whether it is a good idea to test a private method or not? Often I have seen there are two school of thoughts,

  1. Private methods should be tested.
  2. Private methods should not be tested.

To put these things in perspective, let us consider a system under test (SUT) Salary class as shown in the listing below.


A system under test Salary class has two functions:

  1. The CalculateSal method is a public method and it takes two parameters to calculate the salary
  2. The isValidwd method is a private method and it takes one parameter. This function returns true if the number of working days are more than 8, or else it returns false.
  3. The CalculateSal method first checks whether the number of working days is valid or not using the private method isValidWd.
  4. If the number of working days is valid, then salary is calculated by the multiplication of basic salary and the number of working days, or else it is fixed at $1000.

How to create an Azure-based real time Chat Application using Firebase and jQuery

In this post, we’re going to show you step by step instructions on how to create a Chat application that’s similar to a group chat messenger where many people at any given time can read and send messages with the group. In this example we’re going to use the following technologies:

  1. Firebase
  2. HTML
  3. Bootstrap
  4. jQuery

Eventually we will host the application on the Microsoft Azure website, and we’ll use Visual Studio IDE to develop the application.

You can see the real time chat application we are going to build in this article live at: . Feel free to chat with us at this URL!

Setting up Firebase

Register on and login to access the Firebase portal. In the right hand side, you’ll find the option to create a new app. Give your app a name and the URL to create a new app in Firebase.

About the Topic

SOLID principles are the five basic principles of object-oriented programming and design. Systems created using these principles are easy to extend and maintain over time, making them a wise choice. But where do you begin to learn about them?

In this 2 hrs session, we’ll explore all of the basic SOLID principles, including:

  • The Single responsibility principle;
  • The Open Closed principle;
  • The Liskov substitution principle;
  • The Interface segregation principle; and
  • The Dependency Inversion

Additionally, you’ll learn how to create a system by adhering to the SOLID principles we explore, using C# as a language to understand the principles.

Register here to attend! It’s free!

Hope to see you tomorrow in the event and big thanks to C# corner team for arranging this.
