Test case for 2 dimension (integer) Convex Hull algorithm

I did a 2 dimension Convex Hull algorithm that takes in input a file of points called filename.csv where every point is on a row, and X and Y coordinates are separated by a tab, now I need some test files and their correct results, so i'll understand if my algorithm is doing well. I need some boundary case, so i'll be sure if this algorithm is working. My algorithm accepts only INTEGER points. Can anyone tell me a website or a software to generate auto test-files and their correct result ?
