 ==== Auto-configured Data JDBC Tests
 `@DataJdbcTest` is similar to `@JdbcTest` but is for tests that use Spring Data JDBC repositories.
 By default, it configures an in-memory embedded database, a `JdbcTemplate`, and Spring Data JDBC repositories.
-Regular `@Component` and `@ConfigurationProperties` beans are not scanned when the `@DataJdbcTest` annotation is used.
+Only `AbstractJdbcConfiguration` sub-classes are scanned when the `@DataJdbcTest` annotation is used, regular `@Component` and `@ConfigurationProperties` beans are not scanned.
 `@EnableConfigurationProperties` can be used to include `@ConfigurationProperties` beans.
 
 TIP: A list of the auto-configurations that are enabled by `@DataJdbcTest` can be <<test-auto-configuration#test-auto-configuration,found in the appendix>>.
