How to add a protected configuration with access to properties to a Spring Boot Test context?

Question

i use JUnit 5 with Spring Boot 2.5.2 . Now i want to write a Unit test, that does not load the full Application context. Therefore i annotate my test like that:

@ExtendWith(SpringExtension.class)
@ContextConfiguration(classes = {ConfigurationA.class})
class Test1{
...
}

In ConfigurationA the Bean1 gets created. The Problem is that the ConfigurationA accesses an ConfigurationB for creating Bean1, but ConfigurationB is protected.

Now i get the following Error:

Error creating bean with name 'Bean1' defined in com.package.sample.config.ConfigurationA: Unsatisfied dependency expressed through method 'createBean1' parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.package.sample.config.ConfigurationB available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

When i change @ContextConfiguration... to @SpringBootTest it works but the whole Context gets loaded.

Is there any solution to load not the whole context?

Answer 1

只需让 ConfigurationA 扩展 ConfigurationB
