我正在使用 JUnit、PowerMock、Spring Test 和内存中的 H2 数据库编写我的单元测试。当我从 Intellij 运行测试时，一切运行正常。但是当我从 maven(从 Intellij 或从命令行)运行测试时，它们失败了。

这是我的配置:

   @EnableTransactionManagement
   @EnableJpaRepositories("my.app.repository")
   public class ApplicationTestConfiguration {
      @Bean
      public SimpleDriverDataSource dataSource() {
         SimpleDriverDataSource simpleDriverDataSource = new SimpleDriverDataSource();
         simpleDriverDataSource.setDriverClass(org.h2.Driver.class);
         simpleDriverDataSource.setUrl("jdbc:h2:mem:./ScenarioService;DATABASE_TO_UPPER=false;DB_CLOSE_DELAY=-1");
         simpleDriverDataSource.setUsername("sa");
         simpleDriverDataSource.setPassword("sa");
         return simpleDriverDataSource;
      }
      (...)
      private Properties hibernateProperties() {
         Properties props = new Properties();
         props.setProperty("hibernate.dialect","org.hibernate.dialect.H2Dialect");
         props.setProperty("hibernate.hbm2ddl.auto", "create-drop");
         props.setProperty("hibernate.show_sql","true");
         return props;
      }
   }

这是一个示例测试:

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {WebAppInitializer.class,ApplicationTestConfiguration.class, DirtiesContextTestExecutionListener.class})
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
public final class ReadTicketsTest {

    @Autowired //this is a spring JPARepository
    protected TestRepository testRepository;

    @Before
    public void init() {
         testRepository.save(engineConfig);
    }

    @Test
    public void ticketShouldBeRead() {
        //assertion code
    }
}

当我从 intelliJ 运行测试并且它们成功时，在 hibernate 日志中我看到类似这样的内容:

Hibernate: drop table EngineConfigs if exists
Hibernate: create table EngineConfigs (id binary(16) not null, created datetime(6) DEFAULT NULL, customData MEDIUMTEXT, customerId binary(16) not null, signature varchar(255), signatureVersion integer, updated datetime(6) DEFAULT NULL, advancedConfiguration TEXT, engineConfigName varchar(255) not null, engineServiceName varchar(255) not null, locked boolean, probabilityMaximum integer not null, primary key (id))

Hibernate: insert into EngineConfigs (created, customData, customerId, signature, signatureVersion, updated, advancedConfiguration, engineConfigName, engineServiceName, locked, probabilityMaximum, id) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
Hibernate: drop table EngineConfigs if exists

这是有道理的，因为预计它将创建数据库，执行测试(因此插入)，然后由于@DirtiesContextAnnotation 而删除所有表。 但是当我从 maven 运行测试时，在 hibernate 日志中我看到类似这样的内容:

Hibernate: drop table EngineConfigs if exists
Hibernate: create table EngineConfigs (id binary(16) not null, created datetime(6) DEFAULT NULL, customData MEDIUMTEXT, customerId binary(16) not null, signature varchar(255), signatureVersion integer, updated datetime(6) DEFAULT NULL, advancedConfiguration TEXT, engineConfigName varchar(255) not null, engineServiceName varchar(255) not null, locked boolean, probabilityMaximum integer not null, primary key (id))

Hibernate: drop table EngineConfigs if exists

后面是实际错误:

此错误与我从连接 URL 中删除参数 ;DB_CLOSE_DELAY=-1 并从 IntelliJ 运行测试时发生的错误完全相同。但是有了这个参数，测试就可以从 IntelliJ 工作，而不是从 maven 工作!我不知道是什么原因造成的，AFAIK maven 不应该影响测试的执行。似乎在执行测试之前关闭了与数据库的连接。帮助!

最佳答案

问题出在我使用的库上。由于我已将库项目加载到 IntelliJ 中，因此当我手动运行测试时，正在使用库代码。但是 Maven 使用了 .m2 存储库中的库，它没有最新的 .jar。这个过时的 jar 有一些东西导致表 EngineConfigs 的创建失败。 如果有人遇到同样的问题，一个有用的技巧是从数据库连接 URL 中删除“:mem”并检查运行测试时生成的 *.trace.db 文件。该跟踪文件将为您提供有关真正的潜在问题的信息。

关于java - 从 maven 但不是从 Intellij 执行时测试失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42679319/
