Question

我正在进行一些集成测试，我需要在测试之间清理数据库，以便我可以做出正确的断言，并且测试不会导致Failed while seeding database或Unable to clean database.之类的错误。

pom：

<dependencyManagement>
  <dependencies>
   <dependency>
    <groupId>org.jboss.arquillian</groupId>
    <artifactId>arquillian-bom</artifactId>
    <version>1.1.2.Final</version>
    <scope>import</scope>
    <type>pom</type>
   </dependency>
  </dependencies>
</dependencyManagement>

   <artifactId>arquillian-persistence-impl</artifactId>
   <version>1.0.0.Alpha5</version>
   <scope>test</scope>
</dependency>

一些测试类：

@RunWith(Arquillian.class)
@UsingDataSet("datasets/empty.yml")
public class SomeServiceCase {

 @EJB
 SomeService someService;

 @Deployment
 public static JavaArchive createDeployment() {
     return ShrinkWrap.create(JavaArchive.class)
             .addPackages(true, "vo")
             .addPackages(true, "service")
             .addPackages(true, "domain")
             .addAsManifestResource("test-persistence.xml", ArchivePaths.create("persistence.xml"));
 }


 @Test
 @UsingDataSet("datasets/someModel/someModels.yml")
 @Cleanup(phase = TestExecutionPhase.AFTER, strategy = CleanupStrategy.STRICT)
 public void teastSomething() {
    //modifies database content here
 }

 @Test
 @UsingDataSet("datasets/someModel/someModels.yml")
 @Cleanup(phase = TestExecutionPhase.AFTER, strategy = CleanupStrategy.STRICT)
 public void testSomethingElse() {
    //needs initial database content for tests to work 
 }

严格的清理策略应该清除数据库但由于外键而失败。所以我尝试通过向Referential Integrity

添加属性来禁用arquillian.xml

<property name="initStatement">SET REFERENTIAL_INTEGRITY FALSE</property>

我怎样才能实现我想要的目标？有什么想法吗？

Answer 1

您可以在persistence.xml中设置数据库模式以进行drop-create。这将迫使每次重新部署从头开始重建数据库（它的东西！）

Answer 2

您必须仔细查看错误消息的堆栈跟踪。通常，根据我的经验，由于外键约束，数据库无法清理......但细节应该出现在堆栈跟踪中。

我不知道您对参照完整性的停用是否有效。我使用注释@ApplyScriptBefore来禁用它。

我喜欢使用liquibase来解决这个问题。它很容易用作maven插件，如下所示：

                <plugin>
                    <groupId>org.liquibase</groupId>
                    <artifactId>liquibase-maven-plugin</artifactId>

                    <executions>
                        <execution>
                            <id>update_test</id>
                            <phase>process-test-classes</phase>
                            <configuration>
                                <promptOnNonLocalDatabase>false</promptOnNonLocalDatabase>
                                <url>${test.db.connectionURL}</url>
                                <defaultSchemaName>${test.hibernate.default_schema}</defaultSchemaName>
                                <username>${test.db.username}</username>
                                <password>${test.db.password}</password>
                                <changeLogFile>db/db.changelog.xml</changeLogFile>
                                <contexts>test</contexts>
                                <changelogSchemaName>${test.hibernate.default_schema}</changelogSchemaName>
                            </configuration>
                            <goals>
                                <goal>dropAll</goal>
                                <goal>update</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>

执行删除和更新的目标是：

<goal>dropAll</goal>
<goal>update</goal>

使用Arquillian进行Java集成测试，数据库清理
