How to test the time-dependent business logic in spring data and spring data rest projects?

Question

What are the best practices to test the time-dependent business logic in Spring Data and Spring Data REST projects? How to set different "system" time in one test method?

For example - we have two different algorithms to solve the same task - one algorithm is used until 11-00, another one - after 11-00.

Or we have a task that must be performed only on Mondays...

If a method depends on the current date or time, add the current time as a parameter:

public void doSomething(LocalDateTime now) {
    // does something time-dependent
}

The real code invokes this method with doSomething(LocalDateTime.now()). The tests invoke this method with "test dates"

doSomething(LocalDateTime.of(2017, 3, 5, 13, 37)); // Sunday
doSomething(LocalDateTime.of(2017, 3, 6, 13, 37)); // Monday

Thanks for your answer, but it is not suitable for this situation. (Do you have an experience in Spring Data or SDR?) – Cepr0 Mar 05 '17 at 17:22
I used some basic functions several times. Do you have an example? – Roland Weisleder Mar 05 '17 at 18:15
