实验二+043+杨晨宇
一、实验目的
掌握基于覆盖理论与基本路径的基本白盒测试方法和实践
二、实验要求
运用逻辑覆盖测试的覆盖准则设计被测程序的测试用例，并运行测试用例检查程序的正确与否，给出程序缺陷小结。
三、实验内容
根据各位同学自己的被测程序，分别作出各类白盒测试技术的用例设计和相应的Junit脚本。
所有的覆盖的技术：语句覆盖、判定覆盖、条件覆盖、判定/条件覆盖、组合覆盖、路径覆盖，基本路径测试方法。
包括的内容有：
1) 被测原代码
被测源码：http://www.cnblogs.com/zenghongyu/p/6626206.html
2）依据覆盖技术，测试用例列表：
因为被测程序没有退出功能，以回到1作为终点
则基本路径的独立路径为
121
1 2 3 4 5 9 1
1 2 3 4 6 7 9
1 2 3 4 6 8 9
3）相应Junit测试脚本、执行结果
语句测试
package Java_1;
import static org.junit.Assert.assertEquals;
import org.junit.Test;
public class PhoneSaleTestSentence {
@Test
public void testSentence1() {
assertEquals("49.0", PhoneSale.commission("5", "5", "5"));
}
@Test
public void testSentence2() {
assertEquals("160.0", PhoneSale.commission("10", "20", "50"));
}
@Test
public void testSentence3() {
assertEquals("540.0", PhoneSale.commission("20", "100", "100"));
}
}
语句测试通过
2、判定覆盖
package Java_1;
import static org.junit.Assert.assertEquals;
import org.junit.Before;
import org.junit.Test;
public class PhoneSaleTestJudge {
@Before
public void setUp() throws Exception {
}
@Test
public void testJudeg1() {
assertEquals("-1", PhoneSale.commission("10", "-10", "10"));
}
@Test
public void testJudeg2() {
assertEquals("9.8", PhoneSale.commission("1", "1", "1"));
}
@Test
public void testJudeg3() {
assertEquals("205.0", PhoneSale.commission("10", "10", "100"));
}
@Test
public void testJudeg4() {
assertEquals("460.0", PhoneSale.commission("30", "20", "50"));
}
}
判定覆盖测试通过
条件覆盖和条件/判定 、基本路径选取测试用例相同 如下
package Java_1;
import static org.junit.Assert.assertEquals;
import org.junit.Before;
import org.junit.Test;
public class PhoneSaleTestConditon {
@Before
public void setUp() throws Exception {
}
@Test
public void testCondition1() {
assertEquals("-1", PhoneSale.commission("-10", "-10", "-10"));
}
@Test
public void testCondition2() {
assertEquals("100.0", PhoneSale.commission("0", "100", "0"));
}
@Test
public void testCondition3() {
assertEquals("205.0", PhoneSale.commission("15", "50", "0"));
}
@Test
public void testCondition4() {
assertEquals("840.0", PhoneSale.commission("50", "50", "50"));
}
}
条件测试用例通过
4，组合用例
package Java_1;
import static org.junit.Assert.assertEquals;
import org.junit.Before;
import org.junit.Test;
public class PhoneSaleTestConditon {
@Before
public void setUp() throws Exception {
}
@Test
public void testCondition1() {
assertEquals("-1", PhoneSale.commission("-10", "-10", "-10"));
}
@Test
public void testCondition2() {
assertEquals("100.0", PhoneSale.commission("0", "100", "0"));
}
@Test
public void testCondition3() {
assertEquals("205.0", PhoneSale.commission("15", "50", "0"));
}
@Test
public void testCondition4() {
assertEquals("840.0", PhoneSale.commission("50", "50", "50"));
}
}
组合覆盖测试用例通过
4）给出测试参数化和打包测试的脚本，并生成执行结果
测试参数化
package Java_1;
import static org.junit.Assert.assertEquals;
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 PhoneSaleTest1 {
private String ph;
private String sh;
private String pr;
private String result;
@Parameters
public static Collection<Object[]> data() {
return Arrays.asList(new Object[][] { { "5", "5", "5", "49.0" }, { "10", "20", "50", "160.0" },
{ "20", "100", "100", "540.0" }, { "10", "-10", "10", "-1" }, { "1", "1", "1", "9.8" },
{ "10", "10", "100", "205.0" }, { "30", "20", "50", "460.0" }, { "-10", "-10", "-10", "-1" },
{ "0", "100", "0", "100.0" }, { "15", "50", "0", "205.0" }, { "50", "50", "50", "840.0" },
{ "10", "10", "-10", "-1" }, { "10", "-10", "10", "-1" }, { "-10", "10", "10", "-1" },
{ "10", "-10", "-10", "-1" }, { "-10", "10", "-10", "-1" }, { "-10", "-10", "10", "-1" }, });
}
public PhoneSaleTest1(String ph, String sh, String pr, String result) {
this.ph = ph;
this.sh = sh;
this.pr = pr;
this.result = result;
}
@Test
public void testCommission() {
assertEquals(result, PhoneSale.commission(ph, sh, pr));
}
}
打包测试的脚本，并生成执行结果
package Java_1;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;
@RunWith(Suite.class)
@SuiteClasses({ PhoneSaleTest1.class, PhoneSaleTestConditon.class, PhoneSaleTestGroup.class, PhoneSaleTestJudge.class,
PhoneSaleTestSentence.class })
public class AllTests {
}
全部通过
4、测试小结：
- 测试找到的缺陷清单
- 本次测试没有发现缺陷
- 对源代码的修改建议
- 1、建议添加退出程序的功能
- 2、建议把函数返回值设置浮点型，把参数设置为整型
- 测试总结与心得体会
- 通过本次测试把白盒测试的几种覆盖测试的定义和具体方法复习了一遍，包括语句覆盖、判定覆盖、条件覆盖、判定/条件覆盖、组合覆盖、路径覆盖，基本路径测试方法。同时学习了JUNIT4的几种基本方法，包括参数化测试和打包测试。
