Can this be defined inside PrintPreviewWebUITest constructor as a member var
instead of a global?

Done.

It does not have to be in this CL, but eventually we should stop accessing
private member variables. Specifically for NativeLayer,

Approach 1: Using Dependency Injection as folows:

var nativeLayer = new NativeLayerStub();
printPreview = new print_preview.PrintPreview(nativeLayer);

Then instead of
printPreview.nativeLayer_.whenCalled('getInitialSettings')...
we can do
nativeLayer.whenCalled('getInitialSettings')

This way you also don't need to replace the constructor as follows.
print_preview.NativeLayer = NativeLayerStub;


Approach 2: Factory method

// native_layer.js

var instance_ = null;

// Create a static factory method. By default creates a prod NativeLayer.
NativeLayer.getInstance = function() {
 if (!instance_ == null)
   instance_ = new NativeLayer();
 return instance_;
};

NativeLayer.setInstance = function(instance) {
  instance_ = instance;
};

Then you change PrintPreview constructor to call getInstance(). In tests, you
call setInstance() first, before you create a PrintPreview() object.

[rbpotter, 2017/05/18 23:40:57]

Will do this in a follow-up CL. Do we want to change to something like
this for all the member variables accessed? In addition to the two
here we access previewGenerator_, printTicketStore_, destinationStore_,
etc in various tests.

[dpapad, 2017/05/19 00:10:18]

For previewGenerator_, printTicketStore_ and destinationStore_ just exposing a
public getter might be enough. Unlike nativeLayer, I don't think we completely
replace those with stub objects. Even so, let's only do one thing at a time, and
nativeLayer seems of higher importance.

Is getInitialSettisgs() called twice here? Once because of createPrintPreview()

If so, and assuming you want to wait on the 2nd time, we need to call
