Context hierarchy in Spring Boot based tests

Question

My Spring Boot application is started like this:

new SpringApplicationBuilder()
  .sources(ParentCtxConfig.class)
  .child(ChildFirstCtxConfig.class)
  .sibling(

Update: This issue was fixed in Spring Boot 1.5.0 as mentioned by Peter Davis.

This is a limitation of @SpringBootTest. Move accurately, it's a limitation of SpringBootContextLoader. You could work around it by using a custom context loader that configures the parent context or with a ContextCustomizer the factory for which would need to be listed in spring.factories. Here's a rough example of the latter:

src/test/resources/META-INF/spring.factories:

org.springframework.test.context.ContextCustomizerFactory=\
com.alex.demo.ctx.HierarchyContextCustomizerFactory

src/test/java/com/alex/demo/ctx/HierarchyContextCustomizerFactory.java:

package com.alex.demo.ctx;

import java.util.List;

import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.test.context.ContextConfigurationAttributes;
import org.springframework.test.context.ContextCustomizer;
import org.springframework.test.context.ContextCustomizerFactory;
import org.springframework.test.context.MergedContextConfiguration;

public class HierarchyContextCustomizerFactory implements ContextCustomizerFactory {

    @Override
    public ContextCustomizer createContextCustomizer(Class<?> testClass,
            List<ContextConfigurationAttributes> configAttributes) {
        return new ContextCustomizer() {

            @Override
            public void customizeContext(ConfigurableApplicationContext context,
                    MergedContextConfiguration mergedConfig) {
                if (mergedConfig.getParentApplicationContext() != null) {
                    context.setParent(mergedConfig.getParentApplicationContext());
                }

            }

        };
    }

}
