常见的想当然

differenceInBusinessDays from a weekend start to Monday returns 1 business day, and adding zero business days normalizes a weekend date to the next business day

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• differenceInBusinessDays from Saturday or Sunday to Monday returns 0 because no full business day elapsed, whereas Friday to Saturday returns 1
• differenceInBusinessDays from Friday to Monday returns 1 business day, skipping the intervening weekend
• differenceInBusinessDays preserves signed negative values when earlier date is compared to later date
• addBusinessDays on Saturday with amount 0 preserves the Saturday date instead of advancing to Monday
• addBusinessDays advances weekend dates to Monday for positive amounts and subBusinessDays decrements to Friday for negative steps
• isWeekend identifies Saturday and Sunday while returning false for Monday through Friday
• eachWeekendOfInterval returns descending weekend dates for inverted intervals without throwing RangeError
