Question

我有一个JUnit-test，当从mvn测试开始时是成功的，但是从Eclipse开始时失败（参见下面的堆栈跟踪）。我想要做的是使用entityManager.persist（）和entityManager.flush（）将新元素插入数据库（当调用flush时，我收到错误）。

我的config.properties看起来如下：

db.url=jdbc:derby:target/testdb;create=true;territory=en_US;collation=TERRITORY_BASED
db.username=
db.password=

# Hibernate
hibernate.show_sql=true
hibernate.hbm2ddl.auto=create

使用该配置，我的测试在Eclipse中失败，但使用“mvn test”运行;如果我删除“hibernate.hbm2ddl.auto = create”这一行，那么“mvn test”和Eclipse都会成功完成测试。运行应用程序时，它可以工作;在启用“hibernate.hbm2ddl.auto = create”的情况下运行JUnit-Test时，它实际上只会失败。

在我的Test-class中，有一个setup-Method查看以下内容：

  @Before
  @Transactional(propagation = Propagation.REQUIRED, readOnly = false)
  public void setUpDatabase() {
    final Resource deleteScript = applicationContext.getResource("delete.sql");
    final Resource insertScript = applicationContext.getResource("insert.sql");
    SimpleJdbcTestUtils.executeSqlScript(simpleJdbcTemplate, deleteScript, true);
    SimpleJdbcTestUtils.executeSqlScript(simpleJdbcTemplate, insertScript, false);
  }

delete.sql包含“delete from”语句，insert.sql再次插入语句。

Java版本1.6.0_16，maven 2.1.0。

有什么想法吗？

非常感谢，

的Stefan

我忘了：启动时没有错误，但在失败的测试方法中，我在日志中收到以下警告：

Answer 1

基于SQLIntegrityConstraintViolationException看起来你的删除语句没有被执行，你是否有两个delete.sql文件或者没有在Eclipse中配置src / test / resources作为源位置？

applicationContext.getResource("delete.sql")调用将在输出目录中找到delete.sql。在Maven构建中，src / test / resources的内容将被复制到target / test-classes，如果定义了源位置，这只能在Eclipse构建中完成。

第一个true调用结束时的executeSqlScript表示进程将继续运行而不会在发生错误时抛出异常，因此可能是找不到资源，并且删除语句未执行。如果使用设置为false（和现有内容）的选项运行构建，它是否会失败？

注意，您可以配置Eclipse .classpath文件以将测试内容输出到target / test-classes以避免冲突。

执行此操作的步骤如下：

打开项目属性（ alt-enter ）
- 选择 Java构建路径
- 选择来源标签
- 点击允许源文件夹的输出文件夹。这会在源文件夹树中添加一个新条目。
- 展开源文件夹树。
- 双击输出文件夹：条目。
- 会出现一个对话框，询问您是否要使用项目的默认输出文件夹或特定的输出文件夹。选择第二个选项，然后单击浏览...
- 选择所需的文件夹，然后单击“确定”，然后单击“完成”。

您应该在.classpath文件中输入以下条目：

<classpathentry kind="src" output="target/test-classes" path="src/test/java"/>
<classpathentry kind="src" output="target/test-classes" path="src/test/resources"/>

Answer 2

我注意到有时我的单元测试输出会根据使用过的测试工具完成的沙盒级别而变化。例如，Eclipse似乎在相同的上下文中将当前选择（类，包，项目）沙箱放入单个setup-test-teardown周期，而我们的CI似乎将每个单元测试打包为setup-test-teardown周期。

这意味着，如果您的test1有副作用然后在test2中使用，那么可能在Eclipse中工作，但可能< / em>在其他地方失败。如果是这种情况，您需要至少部分重写单元测试以将它们相互分离。

Answer 3

我的评论/问题：

删除行“hibernate.hbm2ddl.auto”时 - 默认操作为无
您使用的基础测试类是什么？尝试扩展类 org.springframework.test.jpa.AbstractJpaTests - 它会在每个方法后回滚
似乎在插入
您的数据库（文件）存储在哪里？也许maven构建干净的数据库文件。
你使用在maven中运行而不是在eclipse中运行的任何maven插件（如hibernate3-maven-plugin）？

编辑：在我看来，测试应该在干净的数据库中运行并保持数据库干净，因此每个测试/方法应该在执行后回滚。查看my qestion和回复。我认为使用hibernate3-maven-plugin是可选的。

Answer 4

这种情况发生在我身上好几个月了，我最终意识到被测试的代码并不像我想象的那样：

如果输入的输入顺序不同，我的代码很容易返回错误的内容
代码迭代了Set而不是List。

因此，在任何给定的会话中，来自Eclipse和Maven的JVM通常会以一致的方式对集合进行排序，但并不总是彼此相同。
