Problem with DB container in TestContainers using SpringBootTest - spring

Question

I have an abstract class BaseIntegrationTest that use TestContainers. The problem is when I'm trying to run a simple DB test like UserRepositoryIntSpec I have an exception, which means that count starts from 114, but not from 1 as expected. Why index not starts from 1? Why every time setup is executed my local db user table is clear, since I expect test to be runned in container with container db usage, so only container table will be cleared.
It's definetly should be something easy I just missed or didn't understand. I will be appreciate for help.
For migrations I'm using Flyway, for testing Spock.
Condition not satisfied:
user1.getId() == 1 && user1.getRiskcustomerid() == 1 && user1.getDateCreated() != null
| | | | |
| 114 | false false
| false
BaseIntegrationTest
#ContextConfiguration
#SpringBootTest(webEnvironment = DEFINED_PORT)
#Testcontainers
#Slf4j
abstract class BaseIntegrationTest extends Specification {
protected static PostgreSQLContainer postgres = new PostgreSQLContainer()
.withDatabaseName("db")
.withUsername("root")
.withPassword("root")
def setupSpec() {
startPostgresIfNeeded()
['spring.datasource.url' : postgres.getJdbcUrl(),
'spring.datasource.username': postgres.getUsername(),
'spring.datasource.password': postgres.getPassword()
].each { k, v ->
System.setProperty(k, v)
}
}
private static void startPostgresIfNeeded() {
if (!postgres.isRunning()) {
log.info("[BASE-INTEGRATION-TEST] - Postgres is not started. Running...")
postgres.start()
}
}
def cleanupSpec() {
if (postgres.isRunning()) {
log.info("[BASE-INTEGRATION-TEST] - Stopping Postgres...")
postgres.stop()
}
}
}
UserRepositoryIntSpec
class UserRepositoryIntSpec extends BaseIntegrationTest {
#Autowired
private UserRepository UserRepository
def setup() {
UserRepository.deleteAll()
}
def "FindAll returns all users correctly"() {
given:
List<Integer> friends = [1,2]
User User1 = User.builder()
.riskcustomerid(1)
.possibleids([1000, 1001])
.preferableid(1000)
.totalfriendscount(2)
.friends(friends)
.build()
User User2 = User.builder()
.riskcustomerid(2)
.possibleids([8000, 8001])
.preferableid(8000)
.totalfriendscount(3)
.friends(friends)
.build()
when:
UserRepository.saveAll([User1, User2])
then:
List<User> Users = UserRepository.findAll()
assert Users.size() == 2
User user1 = Users.get(0)
User user2 = Users.get(1)
assert user1.getId() == 1 && user1.getRiskcustomerid() == 1 && user1.getDateCreated() != null
assert user2.getId() == 2 && user2.getRiskcustomerid() == 2 && user2.getDateCreated() != null
}

I see that you're using url: jdbc:postgresql://localhost:5432/db. You're literally saying "please run against my local DB" :)
For your use case, I suggest using JDBC-based containers in Testcontainers. It will start the container automatically and destroy it when you close your last connection to it.
