I have some unit test classes in my project that I want to test with mvn test. But whenever I run the command an instance of spring boot starts and opens database connections.

I´m running these tests in a server that doesn´t have access to a database, and none of my tests uses one. I just one to execute the tests as the IDE does.

I think one of them could help you

1 - Disable all tests

mvn clean install -DskipTests

2 - Prepare your test for switching

@ExtendWith(SpringExtension.class)
@EnabledIf(expression = "${tests.spring.enabled:true}")

if you pass -Dtests.spring.enabled= false or true will disable test

3 - Point your test to other configuration

@ExtendWith(SpringExtension.class)
@TestPropertySource(locations = "classpath:application-${spring.profiles.active:test}.properties")

this way you could connect your application into a local database

4 - Change your tests

Use mocks to turn your integration tests into a unit tests or component tests with no connections

The problem I had was an empty class with @SpringBootTest annotation. After deleting it the tests works without spring interfering.
