No need for the extra nesting, it can be replaced by chaining, which is always
preferred over nesting.

return nativeLayer.whenCalled('getInitialSettings').then(function() {
  setLocalDestinations();
  return nativeLayer.whenCalled('getPrinters');
}).then(function() {
  var recentList = ...;
  ...
});

[rbpotter, 2017/06/01 22:31:12]

Mostly replaced instances of this sequence with a
helper function, since it is repeated in almost all
of the tests. Thanks for the recommendation though;
will use chaining in future instead of nesting.

[dpapad, 2017/06/01 23:02:33]

We should do this for this CL. Nesting and chaining have slightly different
behavior when it comes to errors. The way the code is now an error in the inner
callback will not be surfaced correctly to the outer. You can verify this with a
minimal example in the dev console.

Try the following:
function foo() {
  return Promise.resolve('foo').then(function() {
    Promise.reject('error');
  });
}
foo().then(function() {console.log('resolved success')}, function(e) {
console.log('resolved with error')})

It erroneously thinks that the outer Promise succeeded.

Now try the following

function foo() {
  return Promise.resolve('foo').then(function() {
    return Promise.reject('error');
  });
}
foo().then(function() {console.log('resolved success')}, function(e) {
console.log('resolved with error')})

It correctly detects that foo() failed. In our case, Mocha relies on the Promise
we return from the test to detect whether the test succeeded or failed. If we
don't get that Promise to properly reject for any inner error, we are breaking
Mocha's contract.
