Running Spring Batch test, doesn't initialize database - spring-batch

Question

Trying to create some end-to-end tests for an spring batch application, which works great. I get an sql error because it is not initializing Spring Batch processing tables: org.postgresql.util.PSQLException: ERROR: relation "batch_job_instance" does not exist
I have this code in the src/test/resources/application.properties:
spring.datasource.initialize=true
spring.datasource.initialization-mode=always
spring.datasource.platform=postgresql
spring.batch.initialize-schema=always
Which is the same I have on `src/main/resources/application.properties and works.
This is the code I have for ApplicationTest:
#RunWith(SpringRunner.class)
#ContextConfiguration(classes={
TestConfiguration.class,
JobCompletionNotificationListener.class,
BatchConfiguration.class
})
#SpringBatchTest
public class ApplicationTests {
#Autowired
private JobLauncherTestUtils jobLauncherTestUtils;
#Test
public void testJob() throws Exception {
JobExecution jobExecution = jobLauncherTestUtils.launchJob();
}
}
I have an specific TestConfiguration to generate a Bean with the DataSource.
#Configuration
#PropertySource("application.properties")
public class TestConfiguration {
#Autowired
private Environment env;
#Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getProperty("spring.datasource.driverClassname"));
dataSource.setUrl(env.getProperty("spring.datasource.url"));
dataSource.setUsername(env.getProperty("spring.datasource.username"));
dataSource.setPassword(env.getProperty("spring.datasource.password"));
return dataSource;
}
I was expecting all tables to be created (internal Batch tables and the tables defined in schema-all.sql).
But I get the following error org.postgresql.util.PSQLException: ERROR: relation "batch_job_instance" does not exist.
I don't understand why in the main application all works automagically, and it doesn't in the test.

If a Spring test misses misses the BatchDataSourceInitializer that is being auto-configured by Spring Boot in the actual application, and you don't want to write a full #SpringBootTest, you can selectively add the auto-configuration for Spring Batch by adding the annotation
#ImportAutoConfiguration(BatchAutoConfiguration.class)
This will then provide the initializer for the injected DataSource.
