I try to run DB Integration tests with Spring Boot and Testcontainers but without success
I added testcontainer to my pom.xml
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.testcontainers</groupId>
<artifactId>postgresql</artifactId>
<version>1.10.6</version>
<scope>test</scope>
</dependency>
Here is the extract of application.properties under test/resources folder
spring.datasource.driver-class-name=org.postgresql.Driver
spring.jpa.hibernate.ddl-auto=create-drop
.......
logging.file.name=staffaccess-log.log
spring.jpa.properties.hibernate.default_schema=staffaccess
spring.jpa.show-sql=true
debug=true
logging.level.org.springframework.web=ERROR
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQL94Dialect
........
Here is the class where I create a container definition
@RunWith(SpringRunner.class)
@SpringBootTest
@ContextConfiguration(initializers = {UserRepositoryTCIntegrationTest.Initializer.class})
public class UserRepositoryTCIntegrationTest extends UserRepositoryCommonIntegrationTests {
@ClassRule
public static PostgreSQLContainer postgreSQLContainer = new PostgreSQLContainer("postgres:11.1")
.withDatabaseName("integration-tests-db")
.withUsername("sa")
.withPassword("sa");
static class Initializer
implements ApplicationContextInitializer<ConfigurableApplicationContext> {
public void initialize(ConfigurableApplicationContext configurableApplicationContext) {
TestPropertyValues.of(
"spring.datasource.url=" + postgreSQLContainer.getJdbcUrl(),
"spring.datasource.username=" + postgreSQLContainer.getUsername(),
"spring.datasource.password=" + postgreSQLContainer.getPassword()
).applyTo(configurableApplicationContext.getEnvironment());
}
}
}
But when I run an integration test, I have the following error
java.lang.ExceptionInInitializerError

It seems that there is a problem with docker
I installed docker for windows (I am under windows 10)
as we seem to need a postgres image as the following code suggests
@ClassRule
public static PostgreSQLContainer postgreSQLContainer = new PostgreSQLContainer("postgres:11.1")
I tried to pull the postgres image, but it gives me an error
C:Usersxflamant>docker pull postgres
Using default tag: latest
Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp 34.228.211.243:443: getsockopt: connection refused

I have succeded in pulling docker image of postgres. The issue was that I had to use a proxy for docker.
However, I have another error
My test class is the following
UPDATE
I finally use junit5 and jupiter For debug facility, i modified my test class as follows
And I have an error at the line
the error is
Here is the extract of application.properties
s
UPDATE2
I have hardcoded the datasource.url
And now, I have the following error (Unable to open JDBC Connection for DDL execution)
I found the solution,
in fact I pulled another docker image of Postgres: postgres:13.4-buster. The discussion is closed
