JarCastingTimeMachine
TimeMachine is a small library created to enable easy testing of code using JodaTime for date and time representation and has some logic depending upon getting the current date.
Usage
Suppose you have a ticket that should not be valid three days after its creation. You could write two tests for that:
@Test
public void should_be_valid_after_creation() {
assertTrue(new Ticket().isValid());
}
@Test
public void should_not_be_valid_three_days_after_creation() {
Ticket t = TimeMachine
.goTo(new DateTime().minusDays(3))
.andExecute(new Block<Ticket>() {
public Ticket run() {
return new Ticket();
}
});
assertFalse(t.isValid());
}
Inside the Block, a new instance of DateTime will be created pointing to three days ago, instead of pointing to the current date.
