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

java spring maven-2 surefire spring-test
2022-08-31 09:10:00

我使用JUnit 4和弹簧测试库编写了一些JUnit测试。当我在Eclipse中运行测试时，然后运行良好并通过。但是当我使用Maven运行它们时（在构建过程中），它们会失败，从而导致与弹簧相关的错误。我不确定是什么导致了这个问题，JUnit，Surefire或Spring。这是我的测试代码，弹簧配置以及我从Maven那里得到的异常：

人员服务测试.java

        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());
            }});
    }

答案 1

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），并通过将forkMode设置为始终在pom中的maven surefire配置中解决了这个问题.xml：

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

Surefire 参数：http://maven.apache.org/plugins/maven-surefire-plugin/test-mojo.html

编辑（2014年1月）：

正如Peter Perháč所指出的，forkMode参数自Surefire 2.14起被弃用。从 Surefire 2.14 开始，请使用以下命令：

<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>

有关更多信息，请参见分叉选项和并行测试执行


答案 2

我突然遇到这个错误，我的解决方案是禁用并行运行测试。

您的里程可能会有所不同，因为我可以通过配置sururefire以按“类”运行并行测试来减少失败测试的数量。

            <plugin>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.2</version>
                <configuration>
                    <parallel>classes</parallel>
                    <threadCount>10</threadCount>
                </configuration>
            </plugin>

正如我首先写的那样，这对于我的测试套件来说还不够，所以我通过删除该部分完全禁用了并行。<configuration>
