Surefire不会选择Junit 4测试

Question

我无法让Maven Surefire执行我的JUnit 4测试，即使我尝试了另一篇文章中的所有建议。

我的POM：

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>maven-test</groupId>
  <artifactId>maven-test</artifactId>
  <version>0.0.1-SNAPSHOT</version>

  <dependencies>
    <dependency>
      <groupId>org.junit</groupId>
      <artifactId>com.springsource.org.junit</artifactId>
      <version>4.4.0</version>
      <scope>test</scope>
    </dependency>  
  </dependencies>

  <build> 
    <plugins> 
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.5</source>
          <target>1.5</target>
        </configuration>
      </plugin>  
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.5</version>
      </plugin> 
    </plugins>
  </build> 
</project>

我的测试：

public class TestSimple {

 public void testSurePass()
 {
  int x = 1;
  Assert.assertEquals(1, x);
 }

 @Test
 public void surePass()
 {
  int x = 1;
  Assert.assertEquals(1, x);  
 }
}

Surefire接走了testSurePass，但从来没见过surePass。我试过mvn -X：

Surefire 2.5会自动将junit-3.8.1添加到其测试类路径中。虽然也添加了junit-4.4.0 (不是为了确保触发测试类路径，但为了测试类路径)，但junit-3.8.1似乎优先。根据http://maven.apache.org/surefire/surefire-providers/dependencies.html的说法，Maven的surefire-api项目依赖于junit-3.8.1。

我是不是遗漏了一些配置？

Answer 1

Surefire有一个junit版本的工件检测机制，你可以使用springsource打包的junit工件来欺骗它。您需要将junitartifactname parameter设置为org.junit:com.springsource.org.junit

Answer 2

我迷路了，我无法重现你的问题。但是确实有一个Jira问题(参见EBR-220)解释说，在使用SpringSource打包的JUnit工件时，您需要将以下内容添加到surefire配置中：

<junitArtifactName>org.junit:com.springsource.org.junit</junitArtifactName>

Answer 3

可以将JUnit 4.x与maven 1.x一起使用：

* add Junit 4.X in your dependencies
* Use the JUnit4TestAdapter in your test classes :
  /**

* @return instance of this as Junit test case
  */
  public static junit.framework.Test suite() { return new JUnit4TestAdapter(MyTestClass.class); }

* run maven with a jdk >= 5
