When I start my spring boot application, my database is not initiating

I have one spring-boot test application in which I provide the following configuration in application.yml file. when I start my server using mvn test, it doesn't initiate the database connection, what can be the issue here? Am I missing any dependency in pom.xml?
spring.datasource.driverClassName = com.ibm.db2.jcc.DB2Driver
spring.datasource.url=jdbc:db2://<fullURL>
spring.datasource.username = <uname>
spring.datasource.password = <password>
Following are my dependencies related to spring-boot
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>5.1.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
Here are my boot logs in which I don't see the database connection logs

Couple of things I note:
You are mentioning application.yml but the format of the file is properties
You need to add the Driver in your dependencies for Spring Boot to pick up as well.
If you are running test, and have an applicatio.yml in src/test/resources, it will override the one in src/main/resources

Why spring application is not able to connect to couchbase when running using docker compose

I am trying to run my spring boot application using the docker-compose file but the service running inside the docker container is not able to connect to the database container.
Below is the exception stack trace from docker-compose logs

Docker-Compose Java Springboot and MySQL

I try to use docker-compose to containerize with starting MySQL server container first, and then start a Springboot Container to connect with the MySQL container.
But the Connection is fail(See full version in the terminal log below

How should I make changes to start my MySQL container first, then link it the Springboot Server to MySQL?

Initialization when running Junit Test case in Spring Boot

I'm writing test cases for service and util classes for my spring boot application. Following are snippets from the test cases
FooServiceImplTest.java
#RunWith(SpringRunner.class)
#SpringBootTest
public class FooServiceImplTest {
#Test
//test cases for FooServiceImplTest
}
BarUtilTest.java
#RunWith(SpringRunner.class)
#SpringBootTest
public class BarUtilTest {
#Test
//test cases for BarUtilTest
}
Now, when I run the test cases, I see something like the following in the console
. ____ _ __ _ _
/\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \

So it looks like for every test suite I write, everything is initialized again. That may be one of the reasons that it is taking a lot of time to run the test cases as I add more test suites. Is there anyway to initialize everything once and run all test cases in one go?

How to prevent Spring Tool Suite from adding extra data/details in the console on every compilation

I'm new to Java/Spring and whenever I compile and run a package or class in Spring Tool Suite, I will see the output, but STS will also included a bunch of other information that I'm really not concerned about. How can I make it so that STS only shows me the output and relevant errors and not all the extraneous info like the stuff below:
. ____ _ __ _ _
/\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
\\/ ___)| |_)| | | | | || (_| | ) ) ) )

Apparently you need to change the default logger threshold. This can be done in your application.properties or else directly to your logger config file if you are using any third party logging libraries.
The allowed levels are : ERROR, WARN, INFO, DEBUG, or TRACE.
For Spring Boot the defaults are :
ROOT :
logging.level.root=ERROR
Spring WEB :
logging.level.org.springframework.web: ERROR
In case you are using Hibernate :
logging.level.org.hibernate: ERROR
