英文:
Flyway don't clean database correctly, and execute migration files two times
问题
我正在使用Flyway进行数据库迁移,同时我在我的集成测试中使用FlywayTest
,但是当我创建一个测试时:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = APPApplication.class)
@Rollback
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class, FlywayTestExecutionListener.class})
@FlywayTest
public class RolesRepositoryTest {
...
}
我遇到了这个错误:

这是来自FlywayTestExecutionListener.class
的,但它再次迁移数据库。
为什么Flyway会这样做,以及如何停止它。

当我在我的表中不使用模式名称时,不会出现问题。一切都正常工作。
英文:
I'm using flyway for migration database, as well I use FlywayTest
for my integration tests, but When I create a test using :
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = APPApplication.class)
@Rollback
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class, FlywayTestExecutionListener.class})
@FlywayTest
public class RolesRepositoryTest {
...
}
I get this error :

If you not :
---> Start reset database for 'com.name.project.infrastructure.database.jpa.RolesRepositoryTest'.
This comes from FlywayTestExecutionListener.class
but it migrate the database again.
Why flyway do this, and how can stop this.

The problem is not happen when I don't use schema names in my tables. every thing work fine.

如果您在每个测试中都重用FlywayTestExecutionListener
,那么即使使用beforeTestClass
,每个带有@TestExecutionListeners
的类也将执行设置。
在JUnit中,为一组测试设置资源只需定义一个Rule(适用于JUnit 4)和Extensions(适用于JUnit 5)即可执行一次。
英文:
If you're reusing FlywayTestExecutionListener
on every test, then the setup will be executed per every class with the @TestExecutionListeners
, even if you use beforeTestClass
.
In JUnit, a way to setup resources for a set of tests a single time is to define a Rule (for Unit 4) and Extensions (for JUnit 5).
