h.getNetYearlyIncome() で失敗し、5k が高すぎるようです。私は一日中それに取り組んでいて、それを理解することはできません.
h.getNetYearlyIncome()= h.getGrossYearlyIncome() - h.getTaxesWithheld() が yearlyIncome-taxesWitheld と等しくないのはなぜですか
public void testSalariedEmployeeMakingOver100K() {
SalariedEmployee h = new SalariedEmployeeImpl("John", "Doe", "Mechanical Turk", 1111, 9166.75);
assertEquals(h.getFirstName(), "John");
assertEquals(h.getLastName(), "Doe");
assertEquals(h.getJobTitle(), "Mechanical Turk");
assertEquals(h.getID(), 1111);
assertEquals(h.getMonthlySalary(), 9166.75, 0.005);
assertEquals(h.getGrossYearlyIncome(), 9166.75*12, 0.005);
assertEquals(h.getTaxableIncome(), h.getGrossYearlyIncome(), 0.005);
assertEquals(h.getTaxesWithheld(), 15000.25, 0.005);
assertEquals(h.getNetYearlyIncome(), h.getGrossYearlyIncome()-h.getTaxesWithheld(), 0.005);
