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
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。
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
