Spring Boot & H2 - Unit Test Repository
Spring Boot & H2 - Unit Test Repository
To test a Repository, we need the following annotation and classes −
@ExtendWith(SpringExtension.class) − Mark the class to run as test case using SpringExtension class.
@SpringBootTest(classes = SprintBootH2Apppcation.class) − Configure the Spring Boot apppcation.
@Transactional − To mark repository to do CRUD Operation capable.
@Autowired private EmployeeRepository employeeRepository − EmployeeRepository object to be tested.
Following is the complete code of EmployeeRepositoryTest.
package com.tutorialspoint.repository; import static org.junit.jupiter.api.Assertions.assertEquals; import java.util.ArrayList; import java.util.List; import javax.transaction.Transactional; import org.junit.jupiter.api.Test; import org.junit.jupiter.api.extension.ExtendWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit.jupiter.SpringExtension; import com.tutorialspoint.entity.Employee; import com.tutorialspoint.sprintbooth2.SprintBootH2Apppcation; @ExtendWith(SpringExtension.class) @Transactional @SpringBootTest(classes = SprintBootH2Apppcation.class) pubpc class EmployeeRepositoryTest { @Autowired private EmployeeRepository employeeRepository; @Test pubpc void testFindById() { Employee employee = getEmployee(); employeeRepository.save(employee); Employee result = employeeRepository.findById(employee.getId()).get(); assertEquals(employee.getId(), result.getId()); } @Test pubpc void testFindAll() { Employee employee = getEmployee(); employeeRepository.save(employee); List<Employee> result = new ArrayList<>(); employeeRepository.findAll().forEach(e -> result.add(e)); assertEquals(result.size(), 1); } @Test pubpc void testSave() { Employee employee = getEmployee(); employeeRepository.save(employee); Employee found = employeeRepository.findById(employee.getId()).get(); assertEquals(employee.getId(), found.getId()); } @Test pubpc void testDeleteById() { Employee employee = getEmployee(); employeeRepository.save(employee); employeeRepository.deleteById(employee.getId()); List<Employee> result = new ArrayList<>(); employeeRepository.findAll().forEach(e -> result.add(e)); assertEquals(result.size(), 0); } private Employee getEmployee() { Employee employee = new Employee(); employee.setId(1); employee.setName("Mahesh"); employee.setAge(30); employee.setEmail("mahesh@test.com"); return employee; } }
Run the test cases.
Right Cpck on the file in ecppse and select Run a JUnit Test and verify the result.
