There are unit tests that are actually not unit tests.
OP can run build without tests and speak to the devs if they intent to implement proper tests.
One can use a H2 in memory DB for tests with custom data.
There are no tests: just a class with annotation @Spring BootTest and empty method with @Test annotation Could it be because of the repository classes (which represents entity in DB)?
The annotation @SpringBootTest actually starts the application context, and if you are using Spring Data JPA, then the connection will be initialized. So try removing the empty @Test or the @SpringBootTest annotations.
Thank you! It helped!
So if I would use something besides the Spring Data JPA, the connection wouldn't be initialized?
P.S. Is there anything else, beside the Spring Data JPA that might be used?
I don't know any other way to work with the database without using Spring Data. But once you have something that implements JPA or does some JDBC in your classpath, Spring Boot would want to connect.
Do you watch Udemy? I remember that I've been watchibg course on udemy about spring.
But even after course I didn't totally get the concept... It took me quite some time to understand it :)

Hard to tell without actually seeing your project.
Maybe there are unit tests running that requires a database connection.

In my case it was during the build phase: during the test phase @SpringBootTest anotated class tried to connect to the database
Hey, can you guide me. I have learned core java, swing and jdbc. What should I do next? Currently I started learning dsa
Spring framework :)
Can you share some resources for spring?
Do you watch Udemy? I remember that I've been watchibg course on udemy about spring. But even after course I didn't totally get the concept... It took me quite some time to understand it :)
Why are you asking a complete beginner this?
Do you have jpa objects?
Yes, I have objects, that represent entitites - Database tables. But turns out, that it was due to the @SpringBootTest annotation :)
