Roads concatenation Problem
Consider we have some GIS (Geo Information System) operating
over some road network. Each road represented as array of
two-dimensional geographical points. Road network is a set
of roads.
System has function called Concatenate(). This function
takes raw road network and should return optimized road
network. Optimization lies in concatenating roads with
matching start or end points, i.e. if road AB end point
matches road BC start point, then optimized network should
contain concatenated road AC. Optimized network shouldn’t
contain two roads which can be concatenated.
Your task is to suggest set of test cases for Concatenate()
function in order to make sure it works correctly.
public interface IPoint
{
double Lat { get; }
double Lon { get; }
}
public Road : List<IPoint>
{
}
public RoadNetwork : List<Road>
{
}
public RoadNetwork Concatenate(RoadNetwork roads);

Anyone can please inform me about how to write test cases for any mathematical calculations. Say for example, we have a formula in a given scenario for calculating the interest. The given formula for interest is: (principle * 5)/(12 * 100) In this case, the principle amount may vary. Would like to know how many test cases can be written for this scenario and how can we decide over this. I will be very thankful for the answer....
