軟件測試作業

1、Question

//根據下面三角形程序，結合白盒測試用例設計技術，在Junit工具中編寫對應的單元測試腳本。
package test1;
public class Triangle {
 protected long A, B, C = 0;

 public Triangle(long A, long B, long C) {
  this.A = A;
  this.B = B;
  this.C = C;
 }

 public boolean isTriangle(Triangle tri){
        boolean isTrue = false;
           if((tri.A>0) &&(tri.B>0) &&(tri.C>0)) {
                   if((tri.A<(tri.B+tri.C)) &&(tri.B<(tri.A+tri.C))  
                      &&(tri.C<(tri.A+tri.B)))
          isTrue = true;
         }
          return isTrue;
 }
 public String isType(Triangle tri) {
  String strType = "";
  if (this.isTriangle(tri)) {
   if (tri.A == tri.B && tri.B == tri.C)
    strType = "等邊三角形";

   else if ((tri.A != tri.B) && (tri.B != tri.C) && (tri.A != tri.C))
    strType = "不等邊三角形";

   else
    strType = "等腰三角形";
  }
  return strType;
 }

}

2、Solution

測試代碼如下:

 package test1;

import static org.junit.Assert.*;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

public class TriangleTest {
	
	Triangle triangle;

	@Test
	public void testIsTriangle01() {
		triangle=new Triangle(1, 2, 3);
		assertEquals(false, triangle.isTriangle(triangle));
	}
	
	@Test
	public void testIsTriangle02() {
		triangle=new Triangle(3, 4, 5);
		assertEquals(true, triangle.isTriangle(triangle));
	}
	
	@Test
	public void testIsTriangle03() {
		triangle=new Triangle(3, 4, 5);
		assertEquals(false, triangle.isTriangle(triangle));
	}

	@Test
	public void testIsType01() {
		triangle=new Triangle(2, 2, 3);
		assertEquals("等腰三角形",triangle.isType(triangle));
	}
	
	@Test
	public void testIsType02() {
		triangle=new Triangle(1, 2, 3);
		assertEquals("",triangle.isType(triangle));
	}
	
	@Test
	public void testIsType03() {
		triangle=new Triangle(3, 4, 5);
		assertEquals("不等邊三角形",triangle.isType(triangle));
	}
	
	@Test
	public void testIsType04() {
		triangle=new Triangle(3, 3, 3);
		assertEquals("等邊三角形",triangle.isType(triangle));
	}
	
	@Test
	public void testIsType05() {
		triangle=new Triangle(2, 1, 1);
		assertEquals("等腰三角形",triangle.isType(triangle));
	}

}

測試結果如下：
