/* This is jasmine's implementation of a mock clock, lifted from the depths of
|
|
* jasmine-core and exposed as a standalone module. The interface is just the
|
|
* same as that of jasmine.clock. For example:
|
|
*
|
|
* var mock_clock = require("mock-clock").clock();
|
|
* mock_clock.install();
|
|
* setTimeout(function() {
|
|
* timerCallback();
|
|
* }, 100);
|
|
*
|
|
* expect(timerCallback).not.toHaveBeenCalled();
|
|
* mock_clock.tick(101);
|
|
* expect(timerCallback).toHaveBeenCalled();
|
|
*
|
|
* mock_clock.uninstall();
|
|
*
|
|
*
|
|
* The reason for C&Ping jasmine's clock here is that jasmine itself is
|
|
* difficult to webpack, and we don't really want all of it. Sinon also has a
|
|
* mock-clock implementation, but again, it is difficult to webpack.
