This application is free to use for training purpose. You are not authorized to publish answers in public on blogs, forums, groups, or any other public medium.

I have created this small application in order to provide as an exercise in finding bugs and patterns. It is a little bit weird but so does some applications to test in real environment.

So please add comments or sent an email if you detected some of the patterns or bugs.

Hint:
pattern: There is a regular star polygon drawn that has the number of sides equal to number entered
bug Entering values like “6.” draws a triangle instead of 6 sided star polygon

Edit: I removed the comments with solutions to give opportunity to others to test themselves. If you really want to give the solution please sent at eusebiu.blindu@testalways.com

   Nice puzzle. What’s the mission, though?

   Without a mission, it’s hard to know if I’ve solved the puzzle. But I’ve learned a lot about it.

   I detected the next bugs(?):
   - Entering values not numeric always draw a 3-side triangle.
   - Entering integer values less five don’t draw a star.

   Interesting puzzle, I think there are many traps to think complexly, but simplicity is always best.

   Perhaps too late in responding, but never late to attempt a puzzle, I’ve emailed you my observations… Your feedback is much appreciated.
