### Question:
SolverHandlerContext { public boolean isCurrentChangeSetProcessed() { return isProcessedChangeSet(currentChangeSetId); } SolverHandlerContext(Duration queryShift); long getCurrentChangeSetId(); void setCurrentChangeSetId(long currentChangeSetId); long nextChangeSetId(); boolean isProcessedChangeSet(long changeSetId); boolean isCurrentChangeSetProcessed(); void setProcessedChangeSet(long changeSetId); void clearProcessedChangeSet(); void setTaskChangeTime(long taskId, LocalDateTime changeTime); boolean isProcessedTaskChange(long taskId, LocalDateTime changeTime); void clearTaskChangeTimes(LocalDateTime untilLocalDateTime); void clearTaskChangeTimes(); LocalDateTime getPreviousQueryTime(); void setPreviousQueryTime(LocalDateTime previousQueryTime); LocalDateTime getNextQueryTime(); void setNextQueryTime(LocalDateTime nextQueryTime); LocalDateTime shiftQueryTime(LocalDateTime queryTime);  }### Answer:
@Test public void isCurrentChangeSetProcessed() { context.setCurrentChangeSetId(5); assertThat(context.isCurrentChangeSetProcessed()).isFalse(); context.setProcessedChangeSet(5); assertThat(context.isCurrentChangeSetProcessed()).isTrue(); }
