从单元测试启动和停止 hsqldb
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。我希望能够通过集成测试控制 hsqldb 服务器。我似乎无法从代码中解决所有问题。
更新:
这似乎与类路径中的 hibernate.cfg.xml 文件
org.hsqldb.Server.main(new String[]{});
以及我的 hibernate.cfg.xml 文件中一起工作:
<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 看起来这只是在 Eclipse 中使用 jUnit 和内置测试运行器运行单元测试时才会出现的问题。如果我运行
mvn test
它们会正确执行并且没有异常。就依赖性而言,我是否遗漏了一些东西?我已经使用生成了 eclipse 项目
mvn eclipse:eclipse
,我的 pom 是:

更新 好吧,我不确定这里到底出了什么问题,但我似乎已经修复了它。我删除了 HSQLDB 创建的所有文件,以及 Maven 目标文件夹中创建的所有文件,进行了清理,使用 maven 重新创建了我的 eclipse .project,并在 eclipse 中刷新了该项目。我想我可能有以前的配置遗留下来的东西,导致它失败。
感谢大家的帮助!
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.
Update:
This appears to work along with having a hibernate.cfg.xml file in the classpath:
org.hsqldb.Server.main(new String[]{});
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>
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
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
and my pom is:

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.
Thanks for everyone's help!

我使用以下配置(直接受到 Hibernate 教程)没有任何问题:
使用内存 HSQLDB 时,无需显式启动任何内容。只需使用
mem:
协议,内存数据库就会从 JDBC 启动。另请参阅
I use the following configuration (directly inspired by the Hibernate tutorial) without any problem:
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.See also
尝试将其附加到 jdbc url:
Try appending this to the jdbc url:
在你的关闭方法中只需这样做
In your shutdown method just do
通过 Runtime.getRuntime().exec("shell command here") 启动服务器怎么样?所有测试只需执行一次,因此不会增加太大的延迟。
更新
好的,看起来您已经自己解决了:)
更新 2
要在单元测试之前(或之后)执行一些代码,您可以
然后将您的测试集包装在其中:
new TestWrapper(suite)
What about starting server through
Runtime.getRuntime().exec("shell command here")
? You have to do it only once for all tests, so it won't add too big lag.Update
Ok, looks like you've solved it yourself :)
Update 2
To execute some code once before (or after) unit tests, you can
Then, just wrap your test set in it:
new TestWrapper(suite)
也许这可能有助于在单元测试中以服务器模式启动 HSQL,但在同一个 JVM 中。
示例代码运行org.hsqldb.server.WebServer(即端口80),但您可以使用org.hsqldb.server.Server。您可以在任一端口上调用 setPort 来覆盖默认端口。

Maybe this might help to start HSQL in server mode in a Unit test, but in the same JVM.
Sample code runs org.hsqldb.server.WebServer (i.e. port 80) but you may use org.hsqldb.server.Server. You may call setPort on either to override default port.

检查我的 hsqldb maven 插件:
https://github.com/avianey/hsqldb-maven-plugin
你可以像 jetty-maven-plugin 或 tomee-maven-plugin 一样启动/停止它以进行测试:
check my hsqldb maven plugin :
https://github.com/avianey/hsqldb-maven-plugin
You can just start/stop it like jetty-maven-plugin or tomee-maven-plugin for your tests :
