Example of an Data Factory with hard-coded data inside each factory method

LoanDataFactory.java

public class LoanDataFactory {

    private LoanDataFactory() {}

    public static Loan createLoan() {
        return new LoanBuilder().name("Elias").email("elias@eliasnogueira.com")
                .amount(new BigDecimal("10.000")).installments(8).build();
    }

    public static Loan createLoanWithoutName() {
        return new LoanBuilder().email("elias@eliasnogueira.com")
                .amount(new BigDecimal("10.000")).installments(8).build();
    }

    public static Loan createLoanWithNotValidEmail() {
        return new LoanBuilder().name("Elias").email("not-valid-email")
                .amount(new BigDecimal("10.000")).installments(8).build();
    }

    public static Loan createLoanWithAmountLessThan() {
        return new LoanBuilder().name("Elias").email("elias@eliasnogueira.com")
                .amount(new BigDecimal("900.00")).installments(8).build();
    }

    // other data factories ignored
}
