That would be coming from this class, which also contains the defaults for other flavours of in-mem DBs.

https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot/src/main/java/org/springframework/boot/jdbc/EmbeddedDatabaseConnection.java

H2(EmbeddedDatabaseType.H2, "org.h2.Driver", "jdbc:h2:mem:%s;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE"),

Which get's loaded via, the DataSourceAutoConfiguration if it meets the criteria,

https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration.java

The default for the database name, testdb, comes from a default set in the Datasourceproperties,

https://github.com/spring-projects/spring-boot/blob/master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/jdbc/DataSourceProperties.java

private String name = "testdb";
