as a system user, i need a program that allows me to input three lengths resulting in a type of triangle so that i can do my job more efficiently. acceptance criteria: the input boxes only accept integers when all three lengths are equal the result is an equilateral triangle when two of the lengths are equal the result is an isosceles triangle when none of the lengths are equal the result is a scalene triangle the intent of your testing is to find as many bugs as possible; please detail all test scenarios you would use to test this. input1 input 2 input3 expected result 5 5 5 equilateral
