Testing a custom Angular directive that encapsulates the functionality of SlickGrid

Currently, I am working on testing an angular directive that acts as a wrapper for slickgrid.

'use strict';
describe('Unit: Grid Directive', function() {
  var $scope;
  var element;

  beforeEach(module('grid'));
  beforeEach(inject(function($compile, $rootScope) {
    $scope = $rootScope;    
    element = angular.element('<grid class="slickgrid-table" id="miscGrid" query="query"/>');
    $scope.query = { symbol: 'AAAA' };
    $compile(element)($scope);
    $scope.$digest();
  }));

One issue I encountered is that slickgrid relies on jquery to locate the correct container for inserting its grid.

Error: SlickGrid requires a valid container, #miscGrid does not exist in the DOM.

My main question now is how can I resolve this issue? Is there a way to trick slickgrid into recognizing that the element being compiled is indeed a valid container?

Answer №1

Instead of trying to deceive anything, I have found it more effective to simply add the element to the DOM in most cases. As seen in an example on the project's GitHub page, the control must be present in the DOM for proper initialization ()

I usually include the following lines in all directive specs

var sandbox;
beforeEach(function() { sandbox = angular.element('<div>'); angular.element(document.body).append(sandbox); });
afterEach(function() { sandbox.remove(); sandbox = null; });

Simply add your directive to the sandbox before compiling it.
