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所有问题。
更新
这似乎与在类路径中包含hibernate.cfg.xml文件一起工作:
org.hsqldb.Server.main(new String[]{});
并在我的hibernate.cfg.xml文件中:
<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,使用jUnit和内置测试运行器从Eclipse中运行单元测试时,这只是一个问题。如果我跑
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
生成了eclipse项目mvn eclipse:eclipse

更新 好吧,不知道这里究竟出了什么问题,但我似乎已经修好了。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创建文件,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留了一些东西而已经把它扔掉了。
感谢大家的帮助!

我使用以下配置(直接受Hibernate tutorial启发)没有任何问题:
<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开始。

在关机方法中,只需执行

通过Runtime.getRuntime().exec("shell command here")
启动服务器怎么样?对于所有测试,您只需要执行一次,因此不会增加太大的延迟。

好吧,看起来你自己解决了这个问题:)
更新2
要在单元测试之前(或之后)执行一次代码,您可以
static class TestWrapper extends TestSetup {
TestWrapper(TestSuite suite) {
super(suite);
}
protected void setUp() throws Exception {
// start db
}
protected void tearDown() throws Exception {
// kill db
}
}
然后,只需将测试集包装在其中:new TestWrapper(suite)

检查我的hsqldb maven插件: https://github.com/avianey/hsqldb-maven-plugin
您可以像测试中的jetty-maven-plugin或tomee-maven-plugin一样启动/停止它:
<plugin>
<!-- current version -->
<groupId>fr.avianey.mojo</groupId>
<artifactId>hsqldb-maven-plugin</artifactId>
<version>1.0.0</version>
<!--
default value for in memory jdbc:hsqldb:hsql://localhost/xdb
override only values you want to change
-->
<configuration>
<driver>org.hsqldb.jdbcDriver</driver>
<path>mem:test</path>
<address>localhost</address>
<name>xdb</name>
<username>sa</username>
<password></password>
<validationQuery>SELECT 1 FROM INFORMATION_SCHEMA.SYSTEM_USERS</validationQuery>
</configuration>
<!-- call start and stop -->
<executions>
<execution>
<id>start-hsqldb</id>
<phase>pre-integration-test</phase>
<goals>
<goal>start</goal>
</goals>
</execution>
<execution>
<id>stop-hsqldb</id>
<phase>post-integration-test</phase>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>
</plugin>

也许这可能有助于在单元测试中以服务器模式启动HSQL,但是在同一个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。您可以在上面调用setPort来覆盖默认端口。
