如何模拟当前日期？ [英] How to mock current date?

问题描述

我的代码中有一个方法可以验证当日营业。

I have a method in my code which verifies that current day is business. it checks database calendar for this.

方法如下：

public boolean iBusinessDayToday() {
      LocalDate today = LocalDate.now();
      //logic with today
}

我需要为

我希望单元测试不依赖于工作日。

I want that unit test doesn't depends in week day.

您认为需要什么使用powerMockito模拟 LocalDate.now（）的问题？

What do you think need this issue to use powerMockito to mock LocalDate.now() ?

推荐答案

另一种方法是将时钟传递给该方法：

An alternative would be to pass the clock to the method:

public boolean iBusinessDayToday() {
  return iBusinessDayToday(Clock.systemDefaultZone());
}

@VisibleForTesting
boolean iBusinessDayToday(Clock clock) {
      LocalDate today = LocalDate.now(clock);
      //logic with today
}

现在您可以测试第二种方法并传递固定时钟-无需使用模拟框架。

Now you can test the second method and pass a a fixed clock - no need to use a mocking framework.
