Is it versatile? B: Product planning Will it sell? D: Test Can it be made easily, Can it be used without any issues?

out a series of test cases needed to test the following program (in other words, a suﬃcient data set). Example: XX test case 1. This program reads 3 integers from a card. 2. These 3 values represent the lengths of the 3 sides of a triangle. 3. The program will print a message determining if the triangle is a scalene triangle, isosceles triangle, or equilateral triangle. Work 2: Myers triangle problem

Example［A=3,B=4,C=5］ 2. Test case expressing a valid equilateral triangle Example［A=1,B=1,C=1］ 3. Test case expressing a valid isosceles triangle Example［A=2,B=2,C=3］ 4. For a valid isosceles triangle, test case that expresses a combination of three types, including two equilateral triangles [A=B, B=C, C=A] Example［A=3,B=3,C=4］［A=3,B=4,C=3］［A=4,B=3,C=3］ Work 2 (answer): Myers triangle problem

0 Example ［3 patterns in which A=0, B=3 , C=4, and one other is 0］ ［3 patterns where A=0, B=0, C=1, and 2 others are 0］ 6. Test case with a negative number input ﬁeld value ［3 patterns where A=1, B=3, C=14 and 1 other is negative］ ［3 patterns where A=-1, B=-1, C=1 and 2 others are negative］ ［A=-1,B=-1,C=-1］ Work 2 (answer): Myers triangle problem

the ﬁelds are integers above 0, and the sum of the two ﬁelds is equal to the remaining ﬁeld Example［A=1,B=2,C=3］ 8. Test case with three combinations of [A+B=C] in ﬁeld 7 Example［A=1,B=2,C=3][A=1,B=3,C=2][A=3,B=2,C=1] Work 2 (answer): Myers triangle problem

the ﬁelds are integers above 0, and the sum of the two ﬁelds is smaller than the remaining ﬁeld Example［A=1,B=2,C=4］ 10. Test case with three combinations of [A+B<C,B+C<A,C+A<B] in ﬁeld 9 Example［A=1,B=2,C=4］,[A=1,B=4,C=2], [A=4,B=2,C=1] Work 2 (answer): Myers triangle problem

are 0 Example［A=0,B=0,C=0］ 12. Test case in which values have been inputted that are not half-width digit integers Example [decimal point, control code, half-width/full-width space, half-width/full with capital/lower-case letters, half-width/full-width kana, full-width digits, kana, kanji, etc.] 13. Test case in which there are less than 3 input values Sample ［3 patterns in which A=null,B=3,C=4, and one other is blank］ [3 patterns in which A=null,B=null,C=1, other other two are blank] [A=null,B=null,C=null] Work 2 (answer): Myers triangle problem http://blog.livedoor.jp/hime78/archives/50980099.html
