I answered Matthew Heusser’s Testing Challenge in my last post. I figured it was my turn to issue one.
This version of the program takes as input three numbers representing the size of the sides of a triangle. When the user clicks “Draw” the program draws a picture of the triangle with the size of the sides shown in proportion and also displays the type of triangle.
Given that description, and whatever wacky (or realistic) test cases you can imagine, I challenge you to go forth and test! And if you feel so inclined, I invite you to report bugs you find here in the comments. (Remember to document your bugs well enough that someone else can reproduce them.)
