为什么 maven-surefire-plugin 跳过带有日志消息的测试“因为它已经为此配置运行”？

Question

我不明白为什么 maven-surefire-plugin 不运行 jUnit4 测试。我的 pom 是（无法在此处添加，因为“看起来帖子主要是代码”）：http://pastebin.com/Jj3iJZpY

当我执行mvn clean test cmd 窗口显示：

C:\Users\maya\git\services>mvn clean test

测试类是：

  package com.comp.utils.UtilsTest;

    import static org.junit.Assert.assertTrue;
    import org.apache.log4j.Logger;
    import org.junit.Test;



    public class UtilsTest {
         private static final Logger LOG = Logger.getLogger(UtilsTest.class.getName());


        @Test
        public void testHasPersonSameProd() {


             boolean hasSameProduct = false;

            assertTrue("Should be True", hasSameProduct);
        }
    }

为什么 maven-surefire-plugin:2.19 运行两次并且不想运行我的测试类？如何在我的情况下运行测试？谢谢。

鉴于您链接的 pom（实际上应该包含在问题中，因为将来链接可能会断开）：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19</version>
    <executions>
            <execution>
                    <goals>
                            <goal>test</goal>
                    </goals>
            </execution>
    </executions>


    <dependencies>
            <dependency>
                    <groupId>org.apache.maven.surefire</groupId>
                    <artifactId>surefire-junit47</artifactId>
                    <version>2.19</version>
            </dependency>
    </dependencies>

    <configuration>
            <includes>
                    <include>UtilTest.java</include>
            </includes>
    </configuration>
</plugin>

• Maven Surefire 插件运行两次，因为您配置了插件的额外执行，但未提供 id 元素，因此默认情况下它称为 default (maven-surefire-plugin:2.19:test (default))。此执行在 Surefire (maven-surefire-plugin:2.19:test (default-test)) 的开箱即用 Maven 配置之后运行。因此，因此，您有两次执行（default 和 default-test）。删除 Surefire 插件配置中的 executions 部分，您将只有一次执行（default-test）。
• 您在 Surefire 配置中也有一个错字，<include>UtilTest.java</include> 配置指向 UtilTest.java 类，而在您的问题中它被命名为 UtilsTest（注意附加的 's'）。
• 如果测试类位于src/test/java 文件夹下，则无需配置它的包含，因为它也已遵循 Surefire 的默认约定 "**/*Test.java"。
• 您收到的消息 (Skipping execution of surefire because it has already been run for this configuration) 是因为 Surefire 插件的 configuration 元素位于任何 executions 元素之外，这意味着适用于所有插件执行，即使是默认的 (default-test) .

所以你可能会从你的 pom 中删除整个 Surefire 插件部分，问题应该得到解决。
