@Test public void test_presentValueSensitivityStrike() { double sensi1 = PRODUCT_PRICER.presentValueSensitivityStrike(CMS_ONE_LEG, RATES_PROVIDER, VOLATILITIES); double sensi2 = PRODUCT_PRICER.presentValueSensitivityStrike(CMS_TWO_LEGS, RATES_PROVIDER, VOLATILITIES); double sensiCms = CMS_LEG_PRICER.presentValueSensitivityStrike(CMS_LEG, RATES_PROVIDER, VOLATILITIES); assertThat(sensi1).isEqualTo(sensiCms); assertThat(sensi2).isEqualTo(sensiCms); }
