Data not being retrieved from embedded H2 datasource in springboot test - unit-testing

Question

I've used this technique before and specifying all the configuration explicitly. The log indicates it's creating the datasource and loading the scripts:
o.s.j.d.e.EmbeddedDatabaseFactory - Starting embedded database: url='jdbc:h2:mem:balancer;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=false', username='sa'
o.s.j.d.i.ScriptUtils - Executing SQL script from class path resource [db/migration/V1_0001__create_queue_server_table.sql]
o.s.j.d.i.ScriptUtils - Executed SQL script from class path resource [db/migration/V1_0001__create_queue_server_table.sql] in 20 ms.
o.s.j.d.i.ScriptUtils - Executing SQL script from class path resource [db/migration/V1_0002__queue_server_entries.sql]
o.s.j.d.i.ScriptUtils - Executed SQL script from class path resource [db/migration/V1_0002__queue_server_entries.sql] in 8 ms.
o.s.o.j.LocalContainerEntityManagerFactoryBean - Building JPA container EntityManagerFactory for persistence unit 'default'
I am able to invoke the REST webservice and the call goes through to the Repository but nothing is returned. The application works fine when connecting to mysql and returns data that was loaded. I cannot see what is missing WRT configuration:
Testcase:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = {QueueServiceApplication.class, TestConfig.class})
#WebAppConfiguration
#ActiveProfiles({"test"})
public class QueueServiceApplicationTests {
private static final int EXPECTED_SERVER_COUNT = 10;
#Autowired
private WebApplicationContext webCtx;
private MockMvc mvc;
#Before
public void init() {
mvc = MockMvcBuilders.webAppContextSetup(webCtx).build();
}
#Test
public void successListAll() throws Exception {
mvc.perform(get("/listall")).andExpect(status().isOk())
.andExpect(content().contentType(MediaType.APPLICATION_JSON))
.andExpect(jsonPath("$", hasSize(EXPECTED_SERVER_COUNT)));
}
}
Test configuration object for embedded datasource:
#Configuration
#Profile("test")
public class TestConfig {
#Bean
public DataSource dataSource() {
return new EmbeddedDatabaseBuilder()
.addScript("classpath:/db/migration/V1_0001__create_queue_server_table.sql")
.addScript("classpath:/db/migration/V1_0002__queue_server_entries.sql")
.setType(EmbeddedDatabaseType.H2)
.setName("vitel-balancer")
.setScriptEncoding("UTF8")
.build();
}
}
Launcher:
#SpringBootApplication
public class QueueServiceApplication {
public static void main(String[] args) {
SpringApplication.run(QueueServiceApplication.class, args);
}
}
I'm using spring-boot 1.3.2, java 8 update 72

I have been able to address this by changing my TestConfig class
#Configuration
#Profile("test")
public class TestConfig {
#Bean
public DataSource dataSource() {
return new EmbeddedDatabaseBuilder()
.setType(EmbeddedDatabaseType.H2)
.build();
}
#Bean
public ResourceDatabasePopulator populator() {
ResourceDatabasePopulator pop = new ResourceDatabasePopulator();
pop.addScript(new ClassPathResource("db/migration/V1_0001__create_queue_server_table.sql"));
pop.addScript(new ClassPathResource("db/migration/V1_0002__queue_server_entries.sql"));
pop.setContinueOnError(true);
return pop;
}
#Bean
public DataSourceInitializer dbInit(DataSource ds, ResourceDatabasePopulator populator) {
DataSourceInitializer init = new DataSourceInitializer();
init.setDataSource(ds);
init.setDatabasePopulator(populator);
init.setEnabled(true);
return init;
}
}
I'm not sure why this is different that using the EmbeddedDatabaseBuilder and adding the scripts to it. Would be greatful if there is an explaination
