Answer 1

You can have the pre-processor cache your templates to a module, which can then be included prior to your tests:

karma.conf.js

files: [
  ...
  'app/**/*.html'
],

preprocessors: {
  'app/**/*.html': ['ng-html2js']
},

ngHtml2JsPreprocessor: {
   moduleName: 'templates'
},

directive file

...
templateUrl: 'app/path-to-your/template.html',
...

spec file

describe('My directive', function() {

  beforeEach(module('templates'));
  ...
});
