the right way test date & time in java
Рет қаралды 46,818
The practice to test applications that use time is to pass a Clock into any method that requires the current instant and a dependency injection framework is one way to achieve this.

In my opinion, the best and practice way is create an DateProvider interface. Then we will use DI for own services, and in the tests we use mocks for DateProvider interface. For DateProvider implementation we use LocalDateTime api

Suggestion: Try to scroll the screen in a way that the code to be added or removed always stays near the center of the page, that will help people that uses the closed caption to be able to see the code while also reading the captions. When you edit a code that is too close to the bottom of the view-port we can't see it because the captions will be overlaying it.

I would also advise to use FixedClock implementation of Clock (which is a inner class of Clock) instead of mocking. Less mocking is always better, just call Clock.fixed()

@karamelkhalfouni4015 2 жыл бұрын
I had the same problem. It seems like Spring expects a bean definition for the autowired Clock class. To solve that I added a class where I defined the bean. I looks like this : @Configuration public class ClockConfig { @Bean public Clock clock() { return Clock.systemDefaultZone(); } }

Why adding clock if there is simpler way: private final DateTimeService dateTimeService; usage: dateTimeService.now() public class DateTimeService { public Date now() { return new Date();} // make your own implementation } p.s. also it seems your code exposes too much data out of confirmation token -> encapsulation issue.
