AngularJS + Karma + Ng-html2js => Failed to instantiate module …html

Question

I can\'t make Karma working for directives that have external templates.

Here is my karma configuration file :

Answer 1

This may not be your exact issue, but in our application we needed to add the following to karma.conf.js:

ngHtml2JsPreprocessor: {
    cacheIdFromPath: function(filepath) {
        return '/vision/assets/' + filepath;
    }
}

The corresponding preprocessors setting looks like:

preprocessors: {
    'views/**/*.html': 'html2js'
},

My understanding was that this was due to using absolute URLs in AngularJS when specifying templates - which karma was rewriting when running tests?

Anyway hope this helps.
