Test with anotation @DataJpaTest - EmbeddedDatabaseType is required

I want to create test with in memory DB using Spring Boot 1.4.RELEASE. When I added anotation @DataJpaTest to the test and executed the test I'm getting following error:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'dataSource': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: EmbeddedDatabaseType is required; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: EmbeddedDatabaseType is required

My Spring boot properties:

spring.jpa.database=ORACLE
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=validate

spring.datasource.driverClassName=oracle.jdbc.OracleDriver
spring.datasource.url=..
spring.datasource.username=..
spring.datasource.password=..

spring.datasource.max-active=20
spring.datasource.max-idle=5
spring.datasource.min-idle=1
spring.datasource.initial-size=5


spring.datasource.testWhileIdle = true
spring.datasource.timeBetweenEvictionRunsMillis = 20000
#spring.datasource.test-on-borrow=true
spring.datasource.validation-query=select 1 from dual;

spring.jpa.properties.hibernate.order_inserts=true
spring.jpa.properties.hibernate.order_updates=true
spring.jpa.properties.hibernate.jdbc.batch_size=100
spring.jpa.properties.hibernate.cache.use_second_level_cache=false

I was expecting that this annotation will replace my real DB with in memory DB.
