篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了软件测试第一次上机相关的知识,希望对你有一定的参考价值。
一.junit、hamcrest和eclemma的安装:
1.junit和hamcrest在新建了junitHw1工程后在build path里通过add external jars添加junit-4.12.jar和hamcrest-all-1.3.jar。
2.eclemma在eclipse下点击help-eclipse marketplace-find-eclemma安装。
二.编写Triangle以及Triangletest:
1.判断三角形:
package example; /** * Created by Ev_Eraser on 2016/3/18. */ public class Myclass { public String triangle(int a,int b,int c) { if(a + b < c || a + c < b || b+ c < a) return "notTriangle"; if(a == b && b == c) return "isosceles"; if(a == b || b == c || a == c) return "equilateral"; else return "scalene"; } }
2.测试:
package example; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.junit.runners.Parameterized; import java.util.Arrays; import java.util.Collection; import static org.junit.Assert.assertEquals; @RunWith(Parameterized.class) public class MyclassTest { private Myclass myClass; private int input1; private int input2; private int input3; private String expected; public MyclassTest(int input1, int input2, int input3, String expected){ this.input1 = input1; this.input2 = input2; this.input3 = input3; this.expected = expected; } @Before public void setUp() throws Exception { myClass = new Myclass(); } @Parameterized.Parameters public static Collection<Object[]> getData(){ return Arrays.asList(new Object[][]{ {2, 2, 2, "isosceles"}, {2, 2, 3, "equilateral"}, {2, 4, 3, "scalene"}, {2, 9, 2, "notTriangle"} }); } // @After // public void tearDown() throws Exception { // // } @Test public void testTriangle() throws Exception { assertEquals(this.expected, myClass.triangle(input1,input2,input3)); } }
