I test a service class like this. MockDAO is just stub methods and I override the methods (e.g., getMonthRecordsBefore) that I know the service's method is supposed to invoke. I don't test with the method parameters in this case, because they are simply passed through from the service method to the DAO method.
public void testGetBalanceBeforeDate() {
LedgerService service = new LedgerService();
service.setDao(new MockDAO() {
@Override
public List<MonthRecord> getMonthRecordsBefore(Employee emp,
DayType dayType, Date beforeDate) {
return new ArrayList<MonthRecord>() {
{
add(new MonthRecord() {
{
setEarned(21.2);
setUsed(3);
setLost(10);
}
});
add(new MonthRecord() {
{
setEarned(5);
setUsed(0);
setLost(0);
}
});
add(new MonthRecord() {
{
setEarned(0.66);
setUsed(1);
setLost(1);
}
});
}
};
}
});
assertEquals(21.2 - 3 - 10 + 5 + 0.66 - 1 - 1, service
.getBalanceBeforeDate(null, null, null), 0.0001);
}
