JUnit 5 tests don't work in the Spring Boot project - spring-boot

Question

I'm trying to run a Unit test in a Spring Boot project.
Here pom.xml

At the root of the folder
test
java
there is a file created by Spring itself
#SpringBootTest
#ExtendWith(SpringExtension.class)
class MyFirstDevopsApplicationTests {
// #Test
void contextLoads() {
assertTrue(true);
}
}
And in the folder
test
java
service
My class with a test
import org.junit.jupiter.api.Test;
class UserServiceTest {
private UserService userService;
#Test
void usersEmptyIfNoUserAdded() {
var users = userService.getAll();
assertTrue(users.isEmpty());
}
}
mvn test
does not find any test.
If you run this class from IDEA by selecting run User Service Test, it throws an error:
org.junit.platform.commons.JUnitException: TestEngine with ID 'junit-jupiter' failed to discover tests
I tried to add all the dependencies as shown on this site:
JUnit 5 Maven Dependency
then
mvn test
returns an error:
Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.2:test (default-test) on project my-first-devops: There are test failures.
Change pom.xml

But it didn't help.
mvn test
