Karma preprocessor not running

My karma.conf.js includes:

plugins: [
    'karma-jasmine',
    'karma-phantomjs-launcher',
    'karma-ng-html2js-preprocessor'
],
preprocessors: {
    '../../mypath/*.html': ['ng-html2js']
},
ngHtml2JsPreprocessor: {
    moduleName: 'templates'
},

(I've tried without specifying any plugins, too.)

My devDependencies include:

"karma-ng-html2js-preprocessor": "^0.2.0"`

My tests include:

beforeEach(module('templates'));

These give the error:

Module 'templates' is not available!

Running karma with --log-level debug, I do not see any [preprocessor.html2js] entries. (I do get Loading plugin karma-ng-html2js-preprocessor.)

What am I doing wrong?

The issues were that the templates must be listed under files as well, and that the glob pattern in preprocessors must match. This is implied by the documentation.

files: [
  '../../Scripts/angular-app/directives/*.html',
  // .js files
],

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

Note that **/*.html does not match parent directories of the basePath.

karma start --log-level debug will display DEBUG [preprocessor.html2js] entries when everything is correct.

I was also able to remove the plugins section.

To get the correct cache ID, I used:

ngHtml2JsPreprocessor: {
    // Load this module in your tests of directives that have a templateUrl.
    moduleName: 'templates',

    cacheIdFromPath: function (filepath) {
        return filepath.substring(filepath.indexOf('/Scripts/angular-app/'));
    }
},

If a template references a custom filter, the filter must be loaded in files and the filter's module must be loaded in your directive tests.
