Spring boot test wrong configuration classes - spring

Question

I am trying to test my repository layer using Spring Boot 2.0.1 but when I run my test class, Spring tries to instantiate a Config class not from the test package.
Here is the test code:
TestConfig.class
#Configuration
#Import(value = {TestDatabaseConfig.class})
#Profile("local")
public class TestConfig {
}
TestDatabaseConfig.class
#Configuration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "logEntityManagerFactory",
transactionManagerRef = "logTransactionManager",
basePackages = { "it.xxx.yyy.repository.log" })
#EntityScan(basePackages = {"it.xxx.yyy.model.log", "it.xxx.yyy.common"})
#Profile("local")
public class TestDatabaseConfig {
#Bean("logDataSourceProperties")
public DataSourceProperties logDataSourceProperties() {
return new DataSourceProperties();
}
#Bean(name = "logDataSource")
public DataSource dataSource(#Qualifier("logDataSourceProperties") DataSourceProperties properties) {
return new EmbeddedDatabaseBuilder()
.setType(EmbeddedDatabaseType.H2)
.addScript("classpath:schema.sql")
.build();
}
#Bean(name = "logEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean logEntityManagerFactory(EntityManagerFactoryBuilder builder,
#Qualifier("logDataSource") DataSource logDataSource) {
return builder.dataSource(logDataSource)
.packages("it.xxx.model.log")
.persistenceUnit("log")
.build();
}
#Bean(name = "logTransactionManager")
public PlatformTransactionManager logTransactionManager(#Qualifier("logEntityManagerFactory")EntityManagerFactory logEntityManagerFactory) {
return new JpaTransactionManager(logEntityManagerFactory);
}
}
When I run this class
#RunWith(SpringRunner.class)
#SpringBootTest
#ActiveProfiles("local")
public class LogRepositoryTest {
#Autowired
private ResultLogRepository resultLogRepository;
#Test
public void init(){
}
}
it says :
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'kafkaProducer': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'kafka.topic.operation' in value "${kafka.topic.operation}"
[...]
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'kafka.topic.operation' in value "${kafka.topic.operation}"
But I cannot understand why it brings up my KafkaProducer.class from my main package (that has #Configuration annotation on it).

Answer 1

In your LogRepositoryTest test class you should indicate the alternate test configuration class that should be taken into account, in your case I think should be the TestConfig.
From Spring Boot documentation:
If you are familiar with the Spring Test Framework, you may be used to using #ContextConfiguration(classes=…​) in order to specify which Spring #Configuration to load. Alternatively, you might have often used nested #Configuration classes within your test.
So annotate LogRepositoryTest with #ContextConfiguration(classes = {TestConfig.class})
#RunWith(SpringRunner.class)
#SpringBootTest
#ActiveProfiles("local")
#ContextConfiguration(classes = {TestConfig.class})
public class LogRepositoryTest {
#Autowired
private ResultLogRepository resultLogRepository;
#Test
public void init(){
}
}
UPDATE
Also annotate your configuration class with:
#EnableAutoConfiguration
Something like:
#Configuration
#EnableAutoConfiguration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "logEntityManagerFactory",
transactionManagerRef = "logTransactionManager",
basePackages = { "it.xxx.yyy.repository.log" })
#EntityScan(basePackages = {"it.xxx.yyy.model.log", "it.xxx.yyy.common"})
#Profile("local")
public class TestDatabaseConfig {
//...
}
UPDATE 2
For error:
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'org.springframework.boot.autoconfigure.jdbc.DataSourceProperties' available: expected single matching bean but found 2: logDataSourceProperties,spring.datasource-org.springframework.boot.autoconfigure.jdbc.DataSourceProperties
Completely remove the method:
#Bean("logDataSourceProperties")
public DataSourceProperties logDataSourceProperties() {
return new DataSourceProperties();
}
and change your:
#Bean(name = "logDataSource")
public DataSource dataSource(#Qualifier("logDataSourceProperties") DataSourceProperties properties) {
// ...
}
to:
#Bean(name = "logDataSource")
public DataSource dataSource(DataSourceProperties properties) {
// ...
}
