该程序主要针对三角形问题，通过输入三角形三条边的取值范围，自动生成边的测试值，并对测试值是否能构成三角形、是否等边三角形、是否等腰三角形、是否直角三角形进行了判定与显示。其中在测试值的生成方式上，采用了两种自动生成方式：一是健壮性测试（所谓的七点法），二是边界值分析（也即五点法）。-The program mainly for the triangle problem, by entering the three sides of the triangle range, automatically generated test edge value, and test whether the value of the triangle pose, whether the equilateral triangle, is it isosceles triangle, right triangle conducted to determine whether and显示. Which the test value is generated, using two types of automatic generation methods: First, robustness testing (the so-called seven-point method), and the other is boundary value analysis (that is, five-point method).
