Setting up the karma ng-html2js preprocessor to locate my templates within a specific folder

Currently, I am facing an issue where I need to set the

templateUrl: "partials/my-directive.html"

However, I find that I have to use

templateUrl: "app/partials/my-directive.html
for it to be loaded by Karma.

This is how my folder structure looks like (following a typical Yeoman setup)

app
    partials
        my-directive.template.html
    directives
        my-directive.js
    app.js

karma.conf.js

Below is the directive implementation in code.

   angular.module("exampleApp")
    .directive("adminMod", function () {
        return {
            restrict: "E",
            templateUrl: "app/partials/admin-mod.html",
            scope: {
                props: "="
            }
        }
    });

Here's a snippet of the unit test.

     beforeEach(module("app/partials/admin-mod.html"));

And here's the relevant part from karma.conf.js file.

      files: [
        'app/bower_components/jquery/jquery.js',
        'app/bower_components/angular/angular.js',
        'app/partials/*.html'
    ],

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

    ngHtml2JsPreprocessor: {

       //prependPrefix: ???? what do I make this 
    },

I aim to make the URL relative to the app folder rather than my karma.conf.file. I've tried various path combinations but haven't found a solution yet. Can someone shed some light on how this should ideally work with a Yeoman generated Angular file structure?

Answer №1

The issue arose when I attempted to utilize

ngHtml2JsPreprocessor: {

   prependPrefix: ???? How should I set this 
},

however, the correct approach would have been

ngHtml2JsPreprocessor: {
    stripPrefix: 'app/',
},

This way, I can maintain the route relative to the app/ directory and include the template as a model in the unit tests like so

beforeEach(module("partials/admin-mod.html"));

which corresponds with the path specified in my directive

templateUrl: "partials/admin-mod.html",
