@SpringBootTest 没有声明每个需要的类

Question

At the moment i need to tell the @SpringBootTest annotation which classes i need for so test. If i won't do that, the classes are not found in the test application context. Except of declaring in every test each single class i just want to provide some kind of configuration class, which defines all needed classes for the test.

At the moment the test is working with the following annotations:

@EnableAutoConfiguration
@SpringBootTest(
    properties = {"spring.jpa.hibernate.naming.implicit_strategy: org.hibernate.boot.model.naming.ImplicitNamingStrategyComponentPathImpl"},
    webEnvironment = WebEnvironment.RANDOM_PORT,
    classes = {
        CategoryController.class,
        CategoryService.class,
        CategoryValidationService.class,
        CategoryNameLengthValidator.class,
        CategoryPositionUniquenessValidator.class,
        GlobalExceptionHandler.class
    }
)

I tried to create an Configuration class and removed the classes from the @SpringBootTest annotation, but then the classes weren't found:

@EnableAutoConfiguration
@SpringBootTest(
    properties = {"spring.jpa.hibernate.naming.implicit_strategy: org.hibernate.boot.model.naming.ImplicitNamingStrategyComponentPathImpl"},
    webEnvironment = WebEnvironment.RANDOM_PORT,
)

And the configuration class:

@Configuration
@ComponentScan(basePackages = {"com.it.mypackage"})
public class ContextConfiguration {
}

But it didn't worked if i don't tell the @SpringBootTest annotation which classes i need during test.

Error which appears:

I think that Spring Boot has not discovered the classes. Check if your path of the TestClasses coresponds with your Classes that you want test.

If your class is here:

/src/main/java/com/example/app/MainApplication.java

then the path to the test class must look like this:

/src/test/java/com/example/app/MainApplicationTest.java

If the path is not like this you have import the classes to SpringBootTest with classes=....
