我在 Spring Web 应用程序中使用 Liquibase。我有一堆实体，在每个实体（如用户、帐户、发票、许可证等）的集成测试中对 REST API 进行了数百次测试。我的所有集成测试在按类运行时都通过了，但其中很多在使用一起运行时失败了gradle test。测试之间很可能存在数据冲突，而且我现在没有兴趣花时间修复清理数据。我更喜欢在每节课后删除数据库和上下文。我想我可以用@DirtiesContext在课堂上，所以我用它进行了测试注释。
@RunWith(SpringRunner.class)
@SpringBootTest(classes = {Application.class, SecurityConfiguration.class},
webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@DirtiesContext
public class InvoiceResourceIntTest {
我看到添加注释后，Web 应用程序上下文会为每个类启动，但是当 Liquibase 初始化发生时，查询不会运行，因为校验和匹配。由于这是一个内存数据库，我预计数据库会与 spring 上下文一起被销毁，但它没有发生。
我还将 jpa hibernate ddl-auto 设置为create-drop但这没有帮助。我正在考虑的下一个选择是mem，将 h2db 写入文件并删除集成测试类文件的 @BeforeClass 中的该文件。我更喜欢自动将数据库删除到内存中，而不是在测试中管理它，但想在这里尝试作为最后一个选择。谢谢您的帮助。
Update:
我更新了测试如下。
@RunWith(SpringRunner.class)
@SpringBootTest(classes = {Application.class, SecurityConfiguration.class},
webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
properties = "spring.datasource.name=AccountResource")
@DirtiesContext
public class AccountResourceIntTest {
我为每个集成测试设置了唯一的名称。我仍然没有看到数据库是新的，因为我只能在日志中看到 Liquibase 校验和。
这是我的 application.yml 中的应用程序配置
spring:
datasource:
driver-class-name: org.h2.Driver
url: jdbc:h2:mem:myApp;DB_CLOSE_DELAY=-1
name:
username:
password:
jpa:
database-platform: com.neustar.registry.le.domain.util.FixedH2Dialect
database: H2
open-in-view: false

naming-strategy: org.springframework.boot.orm.jpa.hibernate.SpringNamingStrategy
properties:
hibernate.cache.use_second_level_cache: false
hibernate.cache.use_query_cache: false
hibernate.generate_statistics: true
