【问题描述】：
我在我的 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，但在使用gradle test。测试之间很可能存在数据冲突，到目前为止，我对花时间修复清理数据不感兴趣。我更喜欢在每节课后删除数据库和上下文。我想我可以在课堂上使用@DirtiesContext，所以我通过测试对其进行了注释。
@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，每个类都会启动 Web 应用程序上下文，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项是代替mem，将h2db 写入文件并在我的集成测试类文件的@BeforeClass 中删除该文件。我更喜欢在内存中自动删除 db 而不是在测试中管理它，但想在这里尝试作为最后的选择。感谢您的帮助。
更新：
我更新了如下测试。
@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。我仍然看不到数据库是新的，因为我只能在日志中看到 Liquibase 校验和。
这是我在 application.yml 中的应用配置
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
show_sql: true
hibernate:
ddl-auto: create-drop
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
hibernate.hbm2ddl.auto: validate
