I am trying to write a JUnit test case for a method to insert timesheet which takes a parameter as employee Id. How should I try?

Question

I tried to create a new object in timesheet type and assign values.But I have a method call insertTimesheet which takes employeeId. As there is no such value for employeeId in timesheet object , the test gets fail.

@Test
public void testInsertTimesheet() {
    Timesheet expectedToSave = new Timesheet( 1001 ,"2019-01-10", "2019-01-05", "comment section is this ", "saved", null, null);  
    int actualInsertData = timesheetRepository.insertTimesheet(expectedToSave, 100789);
    Assertions.assertEquals(expectedToSave, actualInsertData);
}

Answer 1

JdbcTemplate.update() method will return number of rows effected. if not inserted successfully it will throw DataAccessException exception.

@Test
public void testInsertTimesheet() {
    Timesheet expectedToSave = new Timesheet( 1001 ,"2019-01-10", "2019-01-05", "comment section is this ", "saved", null, null);  
    int actualInsertData = timesheetRepository.insertTimesheet(expectedToSave, 100789); //In here number of effected rows is 1 so insertTimeSheet() will return 1
    Assert.assertEquals(1, actualInsertData); //expected value is 1
}
