How can I make this line work in jest ? => jasmine.clock().install();

Question

I have a unit test that use jasmin.clock.install

I have the following error using jest-cli 20.0.4

TypeError: jasmine.clock is not a function

What package should I have in order to have this line work in my unit test :

jasmine.clock().install();

I managed to make it work by downgrading to jest-cli 19.0.1. it would be nice to know the upgrade procedure.

What are you trying to archive, maybe there is an equivalent for this in Jest — Andreas Köberle, Jun 20 '17 at 20:32

From the docs jasmine.clock().install(); is needed to mock out setTimeout calls. So this can be done in Jest by using jest.useFakeTimers();. Have a look at the docs on how to mock timer in Jest. Also have a look at the announcement of v20 to see why the Jasmine stuff does not work anymore
