TDD for Game Of Life

In this blog, I will demonstrate how to do Test-Driven-Development step by step when solving the Game Of Life. In short, doing TDD means we write test before writing code. In this example, I will use C# and Visual Studio for IDE. To solve the Game Of Life, I want to have the following test. I always run test to have the failing result first before altering implementation,  Add cells to a universe, and get all of them [TestMethod] public void UniverseGetAllLivingCells() {     Universe universe = new Universe();     universe.Add(new Cell(1, 1));     universe.Add(new Cell(2, 1));     universe.Add(new Cell(1, 2));     List<Cell> cells = universe.GetAllLivingCells();     Assert.IsTrue(cells.Count == 3); } Implementation public class Universe{         private List<Cell> _livingCells = new List<Cell>();         public List<Cell> GetAllLivingCells()         {             return _livingCells;         }         public void Add(Cell cell)         {             _livingCells.Add(cell);         } }  public class Cell{         public Cell(int row, int col){             Row = row;             Collumn = col;         }         public int Row { get; set; }         public int Collumn { get; set; }            }   Test to add duplicated cells. [TestMethod]         public void UniverseAddDuplicatedLivingCells()         {             Universe universe = new Universe();             universe.Add(new Cell(1, 1));             universe.Add(new Cell(1, 1));             List<Cell> cells = universe.GetAllLivingCells();             Assert.IsTrue(cells.Count == 1);         }        Implementation public class Universe     {         private HashSet<Cell> _livingCells = new HashSet<Cell>();         public List<Cell> GetAllLivingCells()         {             return _livingCells.ToList();         }         public void Add(Cell cell)         {             _livingCells.Add(cell);         } } public class Cell     {         public Cell(int row, int col)         {             Row = row;             Collumn = col;         }         public int Row { get; set; }         public int Collumn { get; set; }         public override bool Equals(object obj)         {             if (obj is Cell)             {                 return Row == (obj as Cell).Row && Collumn == (obj as Cell).Collumn;             }             return false;         }         public override int GetHashCode()         {             return ToString().GetHashCode();         }         public override string ToString()         {             return Row + "," + Collumn;         }     }   Test to get an empty cell by its address.

How to access some bits in a byte?

"How to access some bits in a byte?" - someone suddenly asked me the question today, and frankly, at first, I have no idea. We all know .Net support some shift operator >>, << to move a number of bit, but that's it. Let's look at a byte, a byte contains 8 bits as: Byte:        1  1  1  1  1  1  1  1 Bit No:      8  7  6  5  4  3  2  1 For some memory optimization reasons, we might want to store several information within one byte (or int, long, byte[]...). It's pretty easy, if you want to access bit Number 8, because all we need to do is byte someByte = new byte(); someByte = Convert.ToByte("01101111", 2); var no8bit = someByte >> 7; Here, we instruct the program to move 7 bit to the right, and voilà, bit number 8 it is. But if we need to get from bit 7, it can be tricky, we need to XOR with bit number 8. byte someByte = new byte(); someByte = Convert.ToByte("11101111", 2); var no8bit = someByte >> 7; //1 var no7bit = someByte >> 6 ^ no8bit << 1; // 11 ^ 10 = 1 Why? Because someByte>>6 returns bit number 7 and bit number 8! Recursively, we can get to a general method static byte GetBits(byte b, int from, int to) { return (byte)((b >> from) ^ ((b >> to) << (to - from))); }  Me be obliged spend a even tribrach on 4 up to 8 weeks.
