Enable spring datasource only for ONE test

I have a project so big in which only 3 tests in a class uses a datasource connection, and this connection is optional, so I am interested in only enable the datasource connection by spring in this test.
Looking for the Spring manual I see the option properties = {} in #SpringBootTest to enable some properties and I thought to enable here,
#SpringBootTest(classes = Application.class, webEnvironment = WebEnvironment.RANDOM_PORT, properties = {
"spring.datasource.url=[url]",
"spring.datasource.username=[user]",
"spring.datasource.password=[password]",
"spring.jpa.database-platform = org.hibernate.dialect.PostgreSQLDialect",
"hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect",
"spring.jpa.database=postgresql"})
But when I execute the tests with mvn clean install, in others test it returns me the error;
org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (the profiles "test" are currently active).

Any help?

The solution that I found and works for me it's to exclude for in the application properties 2 autoconfigures classes,
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration
because in my case, I don't want to connect the database in the rest of the application, and in the test that I want to connect the database I added to run this test with the profile "database" and the following properties in the annotation #SpringBootTest,
#ActiveProfiles("database")
#SpringBootTest(classes = Application.class, webEnvironment = WebEnvironment.RANDOM_PORT, properties = {
"spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration",
"spring.datasource.url=[url]",
"spring.datasource.username=[username]",
"spring.datasource.password=[password]",
"spring.jpa.database-platform = org.hibernate.dialect.PostgreSQLDialect",
"hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect",
"spring.jpa.database=postgresql",
"spring.datasource.driver-class-name = org.postgresql.Driver"})
and in the class that I want to test I have an EntityManagerFactory annotated with #Autowired, inside a #Component class. So when Spring tries to construct all the Components of the application to avoid a failure that can occur here if the databases are not enabled, I put
#Autowired(required = false)
Also, to create the bean of the connection I created a bean to create a DataSource only if the profile "database" is enabled, as I put before in the test to run that test with the profile "database",
#Bean
#Profile("database")
public DataSource dataSourceProfile(Environment env)
{
return DataSourceBuilder.create().url(env.getProperty("spring.datasource.url"))
.driverClassName(env.getProperty("spring.datasource.driver-class-name"))
.password(env.getProperty("spring.datasource.password"))
.username(env.getProperty("spring.datasource.username")).build();
}
So with this configuration, only this test tries to connect with the database and the rest of the test doesn't try.

The test class is in my src/test/java under the root project package -
-com.someproject //SpringApplication.run
--com.someproject.test
And contains some basic MVC test, but the app fails before that in my contextLoad() -
#RunWith(SpringRunner.class)
#SpringBootTest
public class SapConnectionApplicationTests {
#Test
public void contextLoads() {
}
}
///EDIT
Running build without tests(-dSkipTest) works, and running the project works, it is only test classes fail.

Try declaring a mocked DataSource bean in your test class:
#MockBean
DataSource dataSource;
Then just mock its methods using Mockito.when.

Spring is telling you that it's trying to create a bean using com.siemens.plm.it.configurator.DatasourceConfigurator.createDatasourceBean, and that that method requires a string, and it isn't sure where to get the string from. So either you need to provide a string that it can autowire, or you have to figure out why Spring is trying to invoke that method during context load.
You say this is only failing during the test run and not when the application is loaded, which ... suggests that somehow the jndi name is available to the application context auto wiring during application startup but not when the test is running. I don't have a great suggestion as to why that would be. If I were trying to debug at this point, I might put a breakpoint on createDatasourceBean and start the application in a debugger and figure out where Spring is getting the jndiName from and maybe that would tell me why it can't do the same thing when running the test.
Spring has a ton of ways in which it can resolve properties and components, which is uber-flexible, but that flexibility has a cost. It can be pretty hard to guess where something is coming from if you're not somewhat familiar with the application.

I want my spring boot application to make a Connection to a JNDI DataSource (server :wildfly)

I have created an spring boot application which is reading database and server configuration from application.properties file,
but when I deploy on wildfly I want application should read database configuration from wildfly's standalone.xml file but still it reads from Application.properties file.
//Spring boot main Application class
#EnableAutoConfiguration
#SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class,
DataSourceTransactionManagerAutoConfiguration.class })
public class DemoWildFlyApplication extends SpringBootServletInitializer
{
public static void main(String[] args) {
SpringApplication.run(DemoWildFlyApplication.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoWildFlyApplication.class);
}
#Bean
#Primary
public DataSource primaryDataSource() {
JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
DataSource dataSource = dataSourceLookup.getDataSource("java:jboss/datasources/primary");
return dataSource;
}
//application.properties file

please suggest a solution.

You need spring.datasource.jndi-name property.
Define it within your application.properties like
spring.datasource.jndi-name=java:jboss/datasources/YourDS
with JNDI name of the datasource. You can see it in wildfly admin console or in standalone.xml(domain.xml).

Getting "Unable to resolve persistence unit" error when building jar without IDE

When i run maven build command in intellij Idea , everything works perfectly .
But when i try to run "mvn clean package" without IDE using maven console i get an error saying unable to resolve persistence unit.
I'm trying to build a bash file where app jar can automatically build and run.That's why i need to run "mvn clean package" without IDE

I also checked IDE's mvn log . It apply the 'default' persistence unit . That's the reason it won't fail the build.

As per #harshavmb 's answer i added

Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}

This is a known-bug observed on spring-boot 1.4 versions, wasn't seen on 1.3.x versions as it was silently swallowed.
As a workaround, you can switch-off spring-boot auto-configuration of Hibernate by adding the below changes.
Add #EnableAutoConfiguration(exclude = HibernateJpaAutoConfiguration.class) to you application class
spring.data.jpa.repositories.enabled=false to your application.properties/yml file
Refer link for more details
Hope this helps and good luck!

Spring context refresh, Component not reloaded properly on Integration Tests

I am trying to write a small library which is used for failsafe.
Basically I am putting registered CircuitBreakers into a hashmap which is hold by a class annotated with #Component.
When running multiple integration tests by one run command, I am facing the issue, that #PostConstruct methods of Beans are re-called by ApplicationContext.refresh() where the hashmap still holds references to the previous referenced Objects. Therefore the map throws IllegalArgumentException since I designed it liked that.
Nonetheless, I think I just miss something to clean the map before the refresh is called.
Is someone here who can give me a hint? The Project can be found here.
The Bean which needs to be cleaned is this.
Best

I also adjusted locally the CircuitBreakerRegistry so that it implements DisposableBean but actually it makes no difference.

Actually I just found out what caused the issue, the map where I registered the CircuitBreaker was static.
#Component
public class CircuitBreakerRegistry {
private static final Map<String, CircuitBreaker> concurrentBreakerMap = new ConcurrentHashMap<String, CircuitBreaker>();
//More code here...
}
