為什么maven-surefire-plugin跳過帶有日志消息“因為已經為此配置運行了”的測試？

Question

我不明白為什么maven-surefire-plugin不運行jUnit4測試。 我的pom是（無法在此處添加它，因為“它看起來大部分是代碼”）： http : //pastebin.com/Jj3iJZpY

當我執行mvn clean test cmd窗口時顯示：

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

測試類是：

  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);
        }
    }

為什么maven-surefire-plugin：2.19運行兩次並且不想運行我的測試類？ 我該如何進行測試？ 謝謝。

給定您鏈接的pom（實際上應該將其包含在問題中，因為將來鏈接可能會斷開）：

<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插件運行了兩次，因為您配置了插件的額外執行，但未提供id元素，因此默認情況下將其稱為default （ maven-surefire-plugin:2.19:test (default) ）。 此執行在Surefire的現成Maven配置之后運行（ maven-surefire-plugin:2.19:test (default-test) ）。 因此，因此，您有兩個執行（ default和default-test ）。 刪除Surefire插件配置上的executions部分，您將只能執行一次（ default-test ）。
• 您在Surefire配置中也有一個錯字， <include>UtilTest.java</include>配置指向UtilTest.java類，而在您的問題中它被命名為UtilsTest （請注意其他“ s”）。
• 如果測試類位於src/test/java文件夾下，則無需配置其包含，因為它也已經遵循Surefire的默認約定"**/*Test.java" 。
• 您Skipping execution of surefire because it has already been run for this configuration的消息（ Skipping execution of surefire because it has already been run for this configuration ）是因為您的Surefire插件的configuration元素在任何executions元素之外，這意味着將應用於所有插件執行，甚至是默認的（ default-test ）。

因此，您可以從pom中刪除整個Surefire插件部分，並且該問題應已解決。
