Additional Auto-configuration and Slicing

Each slice provides one or more @AutoConfigure… annotations that namely defines the auto-configurations that should be included as part of a slice. Additional auto-configurations can be added on a test-by-test basis by creating a custom @AutoConfigure… annotation or by adding @ImportAutoConfiguration to the test as shown in the following example:

Java
Kotlin

import org.springframework.boot.autoconfigure.ImportAutoConfiguration;
import org.springframework.boot.autoconfigure.integration.IntegrationAutoConfiguration;
import org.springframework.boot.test.autoconfigure.jdbc.JdbcTest;

@JdbcTest
@ImportAutoConfiguration(IntegrationAutoConfiguration.class)
class MyJdbcTests {

}

import org.springframework.boot.autoconfigure.ImportAutoConfiguration
import org.springframework.boot.autoconfigure.integration.IntegrationAutoConfiguration
import org.springframework.boot.test.autoconfigure.jdbc.JdbcTest

@JdbcTest
@ImportAutoConfiguration(IntegrationAutoConfiguration::class)
class MyJdbcTests

Make sure to not use the regular @Import annotation to import auto-configurations as they are handled in a specific way by Spring Boot.

Alternatively, additional auto-configurations can be added for any use of a slice annotation by registering them in a file stored in META-INF/spring as shown in the following example:

META-INF/spring/org.springframework.boot.test.autoconfigure.jdbc.JdbcTest.imports

com.example.IntegrationAutoConfiguration

In this example, the com.example.IntegrationAutoConfiguration is enabled on every test annotated with @JdbcTest.

You can use comments with # in this file.

A slice or @AutoConfigure… annotation can be customized this way as long as it is meta-annotated with @ImportAutoConfiguration.
