【问题描述】:
我正在使用 DbUnit 框架对我的 JPA 实体 bean 进行单元测试。我已经从数据库表中生成了实体。并且还将 DB 数据导出到 xml 文件中,DbUnit 在执行测试时可以使用这些文件。
但是对于每个测试,我都会收到以下错误:
Caused by: org.hsqldb.HsqlException: integrity constraint violation: unique constraint or index violation; UK_25T4P9GXGVRCC8R3VL93JKAJE table: NEW_TAB
at org.hsqldb.error.Error.error(Unknown Source)

我的测试persistence.xml如下:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="testPU" transaction-type="RESOURCE_LOCAL">

<class>com.dummy.entity.NewTab</class>
<properties>
<property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver"/>
<property name="javax.persistence.jdbc.url" value="jdbc:hsqldb:mem:UNITTEST"/>

<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
</properties>
</persistence-unit>
</persistence>
每个测试用例都使用:
try {
final DatabaseConnection connection = new DatabaseConnection(jdbcConnection);
//connection.getConnection().prepareStatement("SET DATABASE REFERENTIAL INTEGRITY FALSE").execute();
final DatabaseConfig config = connection.getConfig();
// config.setProperty(FEATURE_QUALIFIED_TABLE_NAMES, true);
config.setProperty(PROPERTY_ESCAPE_PATTERN, "\"?\"");
config.setProperty(PROPERTY_DATATYPE_FACTORY, new HsqldbDataTypeFactory());
final List<IDataSet> dataSets = getDataSets();
if (dataSets != null) {
for (IDataSet dataSet : dataSets) {
dbOperation.execute(connection, dataSet);
}
}
} catch (Exception e) {
throw new RuntimeException(e);
}
对于多个实体的每次测试,我都会收到此错误。所以我不知何故觉得我的配置有问题。如果您有任何想法,请告诉我。
【问题讨论】:
-
所以 NEW_TAB 有一个独特的约束,你尝试做一个 INSERT 并且它违反了这一点。那么为什么不包括实体呢?什么是 UNIQUE 约束?
-
我不知道为什么这个问题被否决了 :( 似乎 DbUnit 存在一些严重的问题。它不尊重数据库限制。所以问题是合法的!
