Junit test for saving data with JPA - spring

Question

Am trying to make a junit test to save data with JPA. Below is my entity class
#Entity
#Table(name="book")
public class test {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="BOOK_REF_ID",nullable=false)
private int bookRefId;
#Column(name="BOOK_CODE",nullable=false)
private String bookCode;
#Column(name="BOOK_NAME",nullable=false)
private String bookDescription;
public int getBookRefId() {
return bookRefId;
}
public void setBookRefId(int bookRefId) {
this.bookRefId = bookRefId;
}
public String getBookCode() {
return bookCode;
}
public void setBookCode(String bookCode) {
this.bookCode = bookCode;
}
public String getBookDescription() {
return bookDescription;
}
public void setBookDescription(String bookDescription) {
this.bookDescription = bookDescription;
}
}
Service class is
public interface BookService()
{
public Book create(Book book);
}
Repository class is
public interface BookRepository extends
JpaRepository<Book,Integer>
{ }
Service Implementation class is
public BookServiceImpli implements BookService()
{
#Resource
BookRepository repository;
#Override
public Book create(Book book) {
// TODO Auto-generated method stub
return repository.save(book);
}
}
Now my test class is
#RunWith(SpringRunner.class)
#DataJpaTest
#SpringBootTest(classes= {JPAConfig.class})
#AutoConfigureTestDatabase(replace=Replace.NONE)
#TestPropertySource(
locations = "classpath:application.properties")
public class TestBook {
#Autowired
private BookService bookService ;
#Test
public void test() {
Book book = new Book();
book.setBookCode("abc");
book.setBookDescription("safd");
bookService.create(book);
}
Application properties contains password and database details and JPAConfig contain JPA configuration details such as entity scan database details. When am trying to run the test case am getting an error like
A component required a bean of type
'com.repository.sample.BookRepository' that could not be found.
I don't have main method in it.Am new to unit testing please anyone help me to solve the issue.
