AngularJS test a directive with replace set to true

Question

My <custom-directive> has replace:true and template: '<img />'. How can I write a unit test for it? I think I want to test that it actually replaces custom-directive with img.

it('should be transformed to <img>', function(){
  var elm = $compile('<custom-directive></custom-directive>')(scope);
  scope.$digest();

  var t = elm.find('img'); // wrong! it replaces the element. it won't find another one inside
 //expect(elm).toBeAnImgElement ?
});

I can't find the correct matcher. The closest case I've seen is checking the contents (elm.html() or elm.text()) but my tag is empty.

wrap your directive in a div like:

describe('Directive: custom', function () {
  beforeEach(module('App'));

  var element, $scope;

  it('should be transformed to <img>', inject(function ($rootScope, $compile) {
    $scope = $rootScope.$new();
    element = angular.element('<div><custom-directive></custom-directive></div>');
    element = $compile(element)($scope);

    expect(element.children('img').length).toBe(1);
  }));
});
