测试的题目

Write a javaprogram for the triangle problem and test the program with Junit.

Description oftriangle problem:

Functiontriangle takes three integers a,b,cwhich are length of triangle sides; calculates whether the triangle isequilateral, isosceles, or scalene.

程序源代码

public class Triangle {

/**
 * 给定三条边a、b、c
 * 判断是否可以构成一个三角形
 * 若可以构成一个三角形，输出三角形的类型 
 **/
public int f_triangle(int i_a, int i_b, int i_c){
if(i_a+i_b>i_c&&i_b+i_c>i_a&&i_c+i_a>i_b){
if(i_a==i_b&&i_b==i_c){
System.out.println("这是一个等边三角形！");
return 1;
}else if(i_a==i_b||i_b==i_c||i_c==i_a){
System.out.println("这是一个等腰三角形！");
return 2;
}else{
System.out.println("这是一个三角形！");
return 3;
}
}else{
System.out.println("这不是一个三角形！");
return 0;
}
}
}

JUnit编写的测试用例的代码

public class TriangleTest {

Triangle c_t=new Triangle();;

@Test
public void testF_triangle_one() {
assertEquals(0, c_t.f_triangle(1, 2, 3));
}

@Test
public void testF_triangle_one_01() {
assertEquals(0, c_t.f_triangle(1, 3, 2));
}

@Test
public void testF_triangle_one_02() {
assertEquals(0, c_t.f_triangle(2, 1, 3));
}

@Test
public void testF_triangle_one_03() {
assertEquals(0, c_t.f_triangle(2, 3, 1));
}

@Test
public void testF_triangle_one_04() {
assertEquals(0, c_t.f_triangle(3, 1, 2));
}

@Test
public void testF_triangle_one_05() {
assertEquals(0, c_t.f_triangle(3, 2, 1));
}

@Test
public void testF_triangle_two() {
assertEquals(1, c_t.f_triangle(3, 3, 3));
}

@Test
public void testF_triangle_three() {
assertEquals(2, c_t.f_triangle(2, 3, 3));
}

@Test
public void testF_triangle_three_01() {
assertEquals(2, c_t.f_triangle(2, 2, 3));
}

@Test
public void testF_triangle_three_02() {
assertEquals(2, c_t.f_triangle(3, 2, 3));
}

@Test
public void testF_triangle_four() {
assertEquals(3, c_t.f_triangle(3, 4, 5));
}

@Test
public void testF_triangle_four_01() {
assertEquals(3, c_t.f_triangle(3, 5, 4));
}

@Test
public void testF_triangle_four_02() {
assertEquals(3, c_t.f_triangle(4, 3, 5));
}

@Test
public void testF_triangle_four_03() {
assertEquals(3, c_t.f_triangle(4, 5, 3));
}
}
