JUnit测试在Eclipse中传递但在Maven Surefire中失败

Abh*_*kar 86 java spring maven-2 spring-test surefire

我已经使用JUnit 4和spring-test库编写了一些JUnit测试.当我在Eclipse中运行测试然后运行正常并通过.但是当我使用Maven运行它们时(在构建过程中),它们无法给出与弹簧相关的错误.我不确定导致问题的是什么,JUnit,Surefire或Spring.这是我的测试代码,弹簧配置和我从Maven获得的异常:

我遇到了同样的问题(JUnit测试在Maven Surefire中失败但在Eclipse中传递)并设法通过将forkMode设置为总是在pom.xml中的maven surefire配置来解决它:

<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PeterPerháč指出的那样,自Surefire 2.14以来,forkMode参数已被弃用.从Surefire 2.14开始使用此代替:

<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,请参阅Fork选项和并行测试执行

  • 很高兴听到.在我的情况下,问题很可能是JUnit测试读取的配置文件留在内存中,破坏了后续测试的结果.当forkMode设置为true时,每个测试类完全独立于另一个测试类,保证执行测试时没有副作用. (5认同)
  • 刚尝试使用surefire 2.16并得到:"自2.14版以来,参数forkMode已被弃用.请改用forkCount和reuseForks." 所以要注意这只适用于2.14之前 (4认同)
  • 加一个用于在两年后更新您的答案 (2认同)

我突然遇到这个错误,我的解决方案是禁用并行运行测试.

你的milage可能会有所不同,因为我可以通过配置surefire以'class'运行并行测试来降低失败测试的数量:

            <plugin>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.7.2</version>
                <configuration>
                    <parallel>classes</parallel>
                    <threadCount>10</threadCount>
                </configuration>
            </plugin>

正如我先写的那样,这对我的测试套件来说还不够,所以我通过删除该<configuration>部分完全禁用了parallel .

我有一个类似的问题,@Autowired测试代码中的注释在使用Maven命令行时不起作用,而它在Eclipse中工作正常.我只是将我的JUnit版本从4.4更新到4.9,问题解决了.

从不同的测试执行结果JUnit run和maven install似乎是一些问题的症状。

在我们的案例中，禁用线程重用测试执行也消除了症状，但代码不是线程安全的印象仍然很强烈。

在我们的例子中，差异是由于存在修改测试行为的 bean。只运行 JUnit 测试会很好，但运行项目install目标会导致测试用例失败。既然是正在开发的测试用例，立马就起了疑心。

这导致另一个测试用例通过 Spring 实例化一个 bean，该 bean 将一直存在，直到执行新的测试用例。bean 的存在正在修改某些类的行为并产生失败的结果。

在我们的案例中，解决方案是去掉 bean，这首先是不需要的（这是复制+粘贴枪的另一个奖品）。

我建议每个有这种症状的人调查根本原因是什么。在测试执行中禁用线程重用可能只会隐藏它。

我有类似的问题,但使用IntelliJ IDEA + Maven + TestNG + spring-test.(弹簧测试当然是必不可少的:))当我更改maven-surefire-plugin的配置以并行禁用运行测试时,它已得到修复.像这样:

这并不完全适合您的情况，但是我有同样的想法-运行Maven的测试目标时，在Eclipse中通过的测试失败。

原来，这是我套件中使用其他软件包进行的测试。这花了我一周的时间来解决！

较早的测试是测试一些Logback类，并从配置文件创建Logback上下文。

后来的测试正在测试Spring的SimpleRestTemplate的子类，并且以某种方式保留了早期的Logback上下文，并启用了DEBUG。这导致在RestTemplate中进行额外的调用以记录HttpStatus等。

检查是否有人遇到过这种情况是另一回事。我通过在Logback测试类中注入一些Mocks来解决了问题，因此没有创建真正的Logback上下文。

您不需要在 JpaTransactionManager 中注入数据源，因为 EntityManagerFactory 已经有一个数据源。请尝试以下操作：

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
   <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
