JUnit测试在Eclipse中通过，但在Maven Surefire中失败

我已经使用JUnit 4和spring-test库编写了一些JUnit测试。当我在Eclipse中运行测试时，可以正常运行并通过。但是，当我使用Maven运行它们（在构建过程中）时，它们无法给出与Spring相关的错误。我不确定是什么引起了问题，JUnit，Surefire或Spring。这是我的测试代码，spring配置以及从Maven获得的异常：

PersonServiceTest.java

public class PersonServiceTest {
    @Autowired
    private PersonService service;
    @Test
    @Transactional
    public void testCreatePerson() {
        Person person = new Person();
        person.setName("abhinav");
        service.createPerson(person);
        assertNotNull(person.getId());
    }
    @Test
    @Transactional
    public void testFindPersons() {
        Person person = new Person();
        person.setName("abhinav");
        service.createPerson(person);
        List<Person> persons = service.findPersons("abhinav");
        toFjList(persons).foreach(new Effect<Person>() {
            public void e(final Person p) {
                assertEquals("abhinav", p.getName());
            }});
    }
}

回答：

我遇到了同样的问题（JUnit测试在Maven Surefire中失败，但在Eclipse中通过了），并设法通过将forkMode 始终设置为pom.xml中的maven surefire配置来解决了这个问题：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.12</version>
    <configuration>
        <forkMode>always</forkMode>
    </configuration>
</plugin>

正如PeterPerháč所指出的那样，自Surefire 2.14开始不推荐使用forkMode参数。从Surefire 2.14开始，请改用此命令：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.16</version>
    <configuration>
        <reuseForks>false</reuseForks>
        <forkCount>1</forkCount>
    </configuration>
</plugin>

以上是 JUnit测试在Eclipse中通过，但在Maven Surefire中失败 的全部内容， 来源链接： utcz.com/qa/405702.html
