C# Advent calendar post: Ensuring Santa's Success With Automated Testing

[SeanKilleen]

(A take on the "mars rover" kata, to introduce automated testing). Examples in NUnit, xUnit, and SpecFlow.)

General idea: a grid of airspace (x,y coords) that Santa flies over to drop presents from.

• We need a SantaSleigh
• It has an on-board navigation system that tells him whether he's over a house.
• North, East, South, and West
• Sleigh can turn right or left
• Can move forward or backward by x amount
• The world wraps around

Steps (stopping points of multiple tests)

• Sleigh starts at 0,0, starts facing North
• Turn left (1-5 times)
• Turn right (1-5 times)
• Traveling East increases x / West decreases
• Traveling North increases y / South decreases
• Wrap around on different size boards (property-based testing)
