In my original PR (#9647) I attempted to solve the problem of
using fake timers in acceptance tests by using the new sinon
clock.tickAsync methods. This way of doing things seems to be flawed,
however, as we are getting random spec timeouts starting with the
bookmark acceptance test where this was introduced.
I think I was going about things the wrong way. This commit introduces
a new function with callback (acceptanceUseFakeClock) that sets up the
fake timers using sinon.useFakeTimers with the shouldAdvanceTime option
set to true. This advances time at a normal rate of 20ms per tick, which
means that we are not freezing any time and existing setTimeout funcs.
should proceed as normal. Along with this the callback passed will
run clock.reset() at the end to make sure all the timers are cleaned
up correctly.
There is an optional third parameter after the callback, which is the
timezone. If the user is logged in for the acceptance test then their
timezone is used, otherwise we default to America/Denver.
Usage is (inside an acceptance test):
```
test("Name of the test", async assert => {
// first parameter is time to start fake clock at
await acceptanceUseFakeClock("2020-05-04T13:00:00", async () => {
// test code goes here e.g. await visit("/url");
});
});
```
Update sinon.js to 9.0.2 to access async fake timers https://sinonjs.org/releases/v9.0.2/fake-timers/ which can then be used with acceptance tests (previously useFakeTimers didn't work with await, e.g. for visit).
Fix the bookmark acceptance test that was time based to use these new fake timers.
Add a fakeTime function that uses moment and the provided date string + timezone to freeze time using useFakeTimers and return a clock.
Add a timeStep function that accepts a clock from fakeTime and a function to run. Once the function is run we call clock.tickAsync(1000) to progress the fake clock forward 1s to progress promises/callbacks.
