Why is $httpBackend.flush() resulting in an "Unexpected request" error for a UI template?

ionic-v1
#1

I have simplified a jasmine test here which should mock FooResource.query(). I know in this example nothing is done with the data but the point is when I do $httpBackend.flush() I get an error about a UI template and I can’t figure out why. :confused:

describe("foo", function() {
  beforeEach(module("acme"));
  beforeEach(inject(function($injector) {
    var $httpBackend, FooResource;
    $httpBackend = $injector.get('$httpBackend');
    FooResource = $injector.get('FooResource');
    $httpBackend.when('GET', /.*\/api\/genre/).respond({});
    console.log('about to query genres');
    FooResource.query();
    $httpBackend.flush();
  }));
  it("should do foo", function() {
    return console.log('foo');
  });
});

Results in this error:

Found this fix (by jdart at https://github.com/angular-ui/ui-router/issues/212) : whitelist all templates:

 $httpBackend.whenGET(/views.*/).respond(200, '');
