### Question:
FaultInfoBuilder { public static StepFaultCause blame(Blame blame) { return new Builder(blame); }  static StepFaultCause blame(Blame blame);  }### Answer:
@Test public void testBlame() throws Exception { FaultInfo faultInfo = FaultInfoBuilder .blame(Blame.CLIENT) .faultCause("InvalidInput") .applicationErrorCode(null) .message("Invalid input") .retrySameLocation(Retry.no()) .retryOtherLocations(Retry.no()) .incidentId(null); assertEquals(faultInfo.getBlame(), Blame.CLIENT); assertEquals(faultInfo.getFaultCause(), "InvalidInput"); assertEquals(faultInfo.getApplicationErrorCode().orNull(), null); assertEquals(faultInfo.getMessage(), "Invalid input"); assertEquals(faultInfo.getRetrySameLocation().orNull(), Retry.no()); assertEquals(faultInfo.getRetryOtherLocations().orNull(), Retry.no()); assertEquals(faultInfo.getIncidentId().orNull(), null); }
