从单元测试中启动和停止hsqldb [英] starting and stopping hsqldb from unit tests
问题描述
我正在尝试在内存模式下使用hsqldb创建集成测试。目前,我必须在运行单元测试之前从命令行启动hsqldb服务器。我希望能够从我的集成测试中控制hsqldb服务器。我似乎无法通过代码解决这个问题。
I'm trying to create integration tests using hsqldb in an in memory mode. At the moment, I have to start the hsqldb server from the command line before running the unit tests. I would like to be able to control the hsqldb server from my integration tests. I can't seem to get this to all work out though from code.
更新:
这个出现与在类路径中使用hibernate.cfg.xml文件一起工作:
This appears to work along with having a hibernate.cfg.xml file in the classpath:
org.hsqldb.Server.main(new String[]{});
和我的hibernate.cfg.xml文件:
and in my hibernate.cfg.xml file:
<property name="connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="connection.url">jdbc:hsqldb:mem:ww</property>
<property name="connection.username">sa</property>
<property name="connection.password"></property>
<property name="connection.pool_size">1</property>
<property name="dialect">org.hibernate.dialect.HSQLDialect</property>
<property name="current_session_context_class">thread</property>
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<property name="hbm2ddl.auto">update</property>
更新
看来这只是一个问题使用jUnit和内置的测试运行器从Eclipse中运行单元测试。如果我运行
Update It appears that this is only a problem when running the unit tests from within Eclipse using jUnit and the built in test runner. If I run
mvn test
它们被正确执行,没有例外。就依赖性而言,我是否遗漏了一些东西?我使用
they are executed correctly and there is no exception. Am I missing something as far as a dependency goes? I have generated the eclipse project using
mvn eclipse:eclipse

更新
好的,不知道这里究竟出了什么问题,但我好像修好了。我删除了HSQLDB创建的所有文件,以及我的Maven目标文件夹中的所有已创建的文件,使用maven做了一个干净的,重新创建的eclipse .project并在eclipse中刷新了项目。我想我可能已经从以前的配置中遗漏了一些东西。
Update Ok, well not sure what exactly was going wrong here, but I seemed to have fixed it. I deleted all the files that HSQLDB created, as well as all of the created files in my Maven target folder, did a clean, recreated my eclipse .project using maven and refreshed the project in eclipse. I think I may have had something left over from a previous configuration that was throwing it off.
感谢大家的帮助!
推荐答案
我使用以下配置(直接受 Hibernate教程)没有任何问题:
I use the following configuration (directly inspired by the Hibernate tutorial) without any problem:
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/>
<property name="hibernate.connection.url" value="jdbc:hsqldb:mem:foobar"/>
<property name="hibernate.connection.username" value="sa"/>
<property name="hibernate.connection.password" value=""/>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<!-- Enable Hibernate's automatic session context management -->
<property name="current_session_context_class">thread</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hibernate.hbm2ddl.auto" value="update"/>
<mapping resource="..."/>
</session-factory>
</hibernate-configuration>
使用内存中的HSQLDB时,无需显式启动任何内容。只需使用 mem:
协议,内存数据库将从JDBC启动。
When using an in-memory HSQLDB, there is no need to start anything explicitly. Just use the mem:
protocol and the in-memory database will get started from JDBC.
