How do I create and use a spring boot testing utility class? - spring-boot

Question

I want to create a utility class just for my tests that have some methods that all tests will use to reduce code duplication.
Where do I create this class and how do I import it in my tests?
Errors
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'FooTest': Unsatisfied dependency
expressed through field 'myTestUtils'; nested exception is
org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type 'com.utils.MyTestUtils' available: expected
at least 1 bean which qualifies as autowire candidate. Dependency
annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
Files
// src/test/com/example/utils/MyTestUtils.java
public class MyTestUtils {
public String foo = "bar";
}
// src/test/com/example/services/FooTest.java
import com.example.utils.TestUtils;
#SpringBootTest
public class FooTest {
// If I remove this decorator I get that this.testUtils is null
#Autowired
MyTestUtils myTestUtils
#Test
public void testFoo() throws Exception {}
Asserthat(myTestUtils.foo).equals("bar")
}
Update
I solved the problem above with annotating the myTestUtils class with #Service
This works.
// src/test/com/example/utils/MyTestUtils.java
#Service
public class MyTestUtils {
public String foo = "bar";
}
