It was nearly 10 years ago I picked up a book called Agile Principles, Patterns and Practises in C# by Robert C. Martin which revolutionised the way I thought about Object Orientated Programming. In this book he discussed SOLID Principles. In this blog series I will discuss each principle with code examples. This will prevent … More SOLID Principles – Part 01 – Overview
In this blog we will continue testing our Scorer class by adding some statistics. Get the Number of Strikes and Spares We need to keep track of the number of Strikes and Spares thrown in a game. Let’s write the tests. [Test] public void Check10SparesWereThrown() { for (int _bowl = 1; _bowl <= 10; _bowl++) … More Unit Testing – C# – Part 06 – Building Out the Class 4
In this blog we will continue testing our Scorer class by adding Spares and Strikes. Adding Spares Looking at the rules for spares. If we knock down 10 pins with 2 bowls, we add 10 plus the value of the next bowl. Here is our failing test. [Test] public void CalculateScoreWithSpares() { _scorer.FrameScore(0, 0); Assert.That(_scorer.Score, … More Unit Testing – C# – Part 05 – Building Out the Class 3
This is a continuation of the last blog where we continue to create tests and code for our Tenpin Bowling Scorer class. Refactoring If you look at the code below you will notice we are instantiating the Scorer class in each test. [TestFixture] public class Scorer_NUnit_Tests { [Test] public void ShouldReturnPlayersName() { var _player = … More Unit Testing – C# – Part 04 – Building Out the Class 2
In the last blog I discussed the project structure and the unit testing frameworks I will use. In this blog I will begin building out the class and tests based on our business requirements. Players Name I need to enter a player’s name and have the ability to get it. I always start our defining … More Unit Testing – C# – Part 03 – Building Out the Class 1
In the last blog I explained the class we are building and its business rules. In this blog I will show you how we setup the visual studio project before we begin writing our tests. Source Code You can find the source for this blog series here. Visual Studio Project The project is developed in … More Unit Testing – C# – Part 02 – Project Structure
In this tutorial series I will be showing how we can develop a ten pin bowling class to calculate a players score using Unit Testing. This makes a difference from the usual calculator demos you normally see. There are myriad of sources that explain Unit Testing and implementing classes using Test Driven Development (TDD), so … More Unit Testing – C# – Part 01 – Tenpin Bowling Scorer
Here is something that is not documented very well. In SQL Server Data Tools projects we have the ability to include SQLCMD variables. The idea is to allow access to a different set of resources at development time without getting compile time errors. In the example below I have variable called LinkedServer that points to … More SQL Server Data Tools – Local SQLCMD Variables
In the last blog I showed you how to create a Logical SQL Server and create a SQL Database. These two operation ran asynchronously therefore the REST API call finished immediately. In this blog I will explain how we monitor asynchronous operations from the REST API. Tracking Asynchronous Azure Operations Some Azure REST operations run … More Azure REST API – Part 06 – Monitoring Async Operations in Postman
In the last blog I should how to retrieve an Azure resource. In this blog I’ll show you how to create one. Creating an Azure Resource Group All Azure resources are created in a resource group so this is a good one to begin with. First of all let’s check if our Resource Group exists. … More Azure REST API – Part 05 – Creating Azure Resources in Postman
