maven2 - 为什么故障安全插件忽略我的junit注释？

Question

我已经建立了一个 java/maven 项目以便以这种方式执行测试：

• 单元测试使用surefire插件执行
• 使用故障安全插件执行集成测试

这里是 POM（丑陋的紧凑格式）：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <groupId>org.sample</groupId>
    <artifactId>sample-service</artifactId>
    <version>0.0.0</version>
    <name>sdp-sample-service</name>

    <build> <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration><debug>true</debug><source>1.6</source><target>1.6</target></configuration>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId><artifactId>maven-surefire-plugin</artifactId><version>2.6</version>
        </plugin>

        <plugin>

                <executions><execution>
                        <id>integration-test</id>
                        <phase>integration-test</phase>
                        <goals>
                            <goal>integration-test</goal>
                            <goal>verify</goal>
                        </goals>
                        <configuration>
                            <junitArtifactName>none:none</junitArtifactName>
                            <failIfNoTests>false</failIfNoTests>
                            <testFailureIgnore>true</testFailureIgnore>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

    <dependencies>
        <dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.8.2</version><scope>test</scope></dependency>                    
    </dependencies>

</project>

我有一个类似这样的示例 UNIT 测试类（又是丑陋的紧凑格式）：

package org.sample;import java.util.logging.Logger;import org.junit.*;
public class SampleUnitTest {
    private static final Logger LOG = Logger.getLogger("SampleUnitTest");    
    @BeforeClass public static void beforeClass() {LOG.info("@BeforeClass");}    
    @Before  public void before() {LOG.info("@Before");}    
    @AfterClass public static void afterClass() { LOG.info("@AfterClass");}    
    @After public  void after() { LOG.info("@After"); }    
    @Test public void test1() { LOG.info("test1");}
    @Test public void test2() { LOG.info("test2");}
}

我有完全相同的集成测试：

package org.sample;import java.util.logging.Logger;import org.junit.*;
public class SampleIT {
    private static final Logger LOG = Logger.getLogger("SampleIT");
    @BeforeClass public static void beforeClass() {LOG.info("@BeforeClass");}
    @Before  public void before() {LOG.info("@Before");}
    @AfterClass public static void afterClass() { LOG.info("@AfterClass");}
    @After public  void after() { LOG.info("@After"); }
    @Test public void test1() { LOG.info("test1");}
    @Test public void test2() { LOG.info("test2");}
}

而maven的输出是：

$ mvn clean install
...
[INFO] [surefire:test {execution: default-test}]
...

问题：为什么故障安全集成测试完全忽略了我的 Junit 注释？

Answer 1

删除

<junitArtifactName>none:none</junitArtifactName> 

来自配置。它强制 Surefire 在 Junit3 模式下运行。
