Test Cases
Serial number	Test input: Three edges (a,b,c)	Test Prophecy (Oracle: Right angle, isosceles, equilateral triangle)
1	Input (1,1,1)	Equilateral triangle
2	Input (3, 4,5)	Right triangle
3	Input (2, 2,1)	Isosceles Triangle
4	Input (3, 3,6)	Not a triangle.
5	Input (3, -3,6)	Illegal
6	Input (-3, 3,6)	Illegal

Sentiment: Equivalence class partitioning is a typical, important black-box test method that divides all possible input data (valid and invalid) into a number of equivalence classes. Then select representative data from each section as a reasonable classification of test cases. Reasonable use of good equivalence class partitioning method can save the test time.
