How to mock angular translate filter in unit tests for directives

Question

In my directive templates, I need to use the angular translate filter as such:

Answer 1

This is the ES6 way:

beforeEach(angular.mock.module('myModule'), ($provide) => {
    $provide.value('$translate', t => ({ then: cb => cb(t) }));
}));   

This does not mock the $translate.instant method. For this you could assign the function to a variable and then assign the angular.identity method to the instantproperty.
