Software Testing, Lab 1
1. Install Junit(4.12), Hamcrest(1.3) with Eclipse
1.在github上下载两个jar包junit-4.12.jar和hamcrest-all-1.3.jar地址为https://github.com/junit-team/junit4/wiki/Download-and-Install
2.打开eclipse,新建项目,点击Project,选择Properties;
弹出如下界面,点击Add External JARs...,添加如上两个jar包。
2. Install Eclemma with Eclipse
将eclemma-2.3.3.zip解压缩到eclipse下的dropins文件夹中,我的路径为:D:\\Download\\eclipse\\eclipse\\dropins\\eclemma-2.3.3。
3. Write a java program for the triangle problem and test the program with Junit.
3.1 Description of triangle problem:
Function triangle takes three integers a,b,c which are length of triangle sides; calculates whether the triangle is equilateral, isosceles, or scalene.
3.2 创建triangles类,编写代码,首先检测三条边是否可以构成三角形,如果构成,那是等边三角形还是等腰三角形或者是不等边三角形。代码如下:
package triangle; public class triangles { public static String triangles(int a,int b,int c){ if(a <= 0 || b <= 0 || c <= 0 || a + b <= c || a + c <= b || b + c <= a) return "Not a triangle"; else { if(a == b && a == c) return "equilateral"; else if(a == b || b == c || a == c) return "isosceles"; else return "scalene"; } } }
3.3 创建测试类,及测试用例,利用JUnit进行测试,代码如下:
package triangle; import static org.junit.Assert.*; import java.util.Arrays; import java.util.Collection; import org.junit.Test; import org.junit.runner.RunWith; import org.junit.runners.Parameterized; import org.junit.runners.Parameterized.Parameters; @RunWith(Parameterized.class) public class testTriangle { private int a; private int b; private int c; private String expected; public testTriangle(int a,int b, int c, String expected){ this.a = a; this.b = b; this.c = c; this.expected= expected; } @Parameters public static Collection<Object[]> getData(){ return Arrays.asList(new Object[][]{ {-1, 1, 2, "Not a triangle"}, {3, 2, 5, "Not a triangle"}, {6, 6, 6, "equilateral"}, {2, 5, 5, "isosceles"}, {7, 8, 9, "scalene"} }); } @Test public void test() { assertEquals(this.expected,triangles.triangles(a,b,c)); } }
3.4 利用JUnit进行测试,如下图,在testTriangle类上点击右键,选择run as, 然后选择JUnit Test。
测试结果如下:
3.5 点击如下图标,利用Eclemma进行覆盖统计。
结果如下图:
可见,对于测试类的覆盖率为100%。
