Testing a directive that has templates all contained within a single file with script tags

I'm struggling to include my directive's templates in my Karma unit tests. The templates are all in one file within different script tags.

The error message I encounter is:

PhantomJS 1.9 (Linux) ERROR
 SyntaxError: Parse error
 at /var/www/html/tweak/core/global/views/js/modules/datable/templates.html:1
PhantomJS 1.9 (Linux): Executed 0 of 0 ERROR (0.313 secs / 0 secs)

Below are the relevant sections of the code:

My directives section:

return {
  scope       : {
    columns : '=',
    config  : '='
  },
  templateUrl : 'datable/table.html',
  restrict    : 'E',
  controller  : 'datableCtrl',
  link        : linkingFunction
};

Template file content:

<script type="text/ng-template" id="datable/table.html">
  <!-- data rows -->
  ...
</script>

<script type="text/ng-template" id="datable/editCell.html">
  ...
</script>

<script type="text/ng-template" id="datable/normalCell.html">
  ...
</script>

Unit tests:

'use strict'

describe("datable", function() {

  describe('directive', function () {
    var $rootScope, $compile, element;

    beforeEach(module('datable'));
    beforeEach(module('/var/www/html/tweak/core/global/views/js/modules/datable/templates.html'));

    beforeEach(inject(function (_$rootScope_, _$compile_) {
      $rootScope = _$rootScope_;
      $compile = _$compile_;

      $rootScope.tableConfig = {
        editable     : true
      };
      $rootScope.columns = [];

      element = angular.element('<datable config="tableConfig" columns="columns"></datable>');

        $compile(element)($rootScope);
        $rootScope.$digest();
    }));

    it('should have ng-scope class', function() {
        expect(element.hasClass('ng-scope')).toBe(true);
    });
  });
});

Karma configuration settings:

var branch = 'tweak';
basePath = '/var/www/html/' + branch + '/';

files = [
  // Dependencies
  JASMINE,
  JASMINE_ADAPTER,
  ...

  // other requirements

  // the project source
  
  // my spec suite
  ...
];

exclude = [

reporters = ['progress'];

runnerPort = 9100;

logLevel = LOG_INFO;
autoWatch = true;
browsers = ['PhantomJS'];

Answer №1

It seems like the error you're encountering is due to attempting to load an HTML file into a file list designed for JavaScript files. However, I have a solution that may help resolve this issue.

Before diving in, I should mention that I am using karma version 0.10.2 while it appears you are on version 0.8.x or below. Although my solution works in 0.10.2, I cannot verify if it will work in 0.8.x. Consider upgrading to the latest version of karma if possible.

Configuration

For 0.10.x:

To load external HTML partials, utilize karma-ng-html2js-preprocessor. This package is typically used for directives with templateUrl in 0.10.2. Ensure the package is installed via npm and add the following code snippet to your karma config:

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

ngHtml2JsPreprocessor: {
    cacheIdFromPath: function(filepath) {
        return 'inlinetemplates';
    },
    moduleName: 'inlinetemplates'
},

plugins: [
    ...,
    'karma-ng-html2js-preprocessor'
],

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

This setup allows you to load a module with module('inlinetemplates') which inserts the main template file's content into $templateCache.

For 0.8.x:

In 0.8.x, use html2js included in karma but less robust compared to 0.10.x. Simply define preprocessors as follows:

preprocessors = { '**/*.html': ['html2js'] }

The generated module and inserted item in $templateCache will be named based on the path referencing the main template html.

Javascript

For 0.10.x:

You can now access the contents of your main template file by loading the relevant module:

var templates = $templateCache.get('inlinetemplates')

To push the inlined templates from the main template file to $templateCache, compile/link the loaded file with angular using:

$compile(templates)(scope);

To implement this, include the following within any describe block where templates need to be loaded.

beforeEach(module('inlinetemplates'));
beforeEach(inject(function($compile, $templateCache, $rootScope) {
    var templatesHTML = $templateCache.get('inlinetemplates');
    $compile(templatesHTML)($rootScope);
}));

For 0.8.x:

var mainTemplateLocation = 'path/used/to/refer/to/main/templates/in/karma/conf.html';
beforeEach(module(mainTemplateLocation));
beforeEach(inject(function($compile, $templateCache, $rootScope) {
    var templatesHTML = $templateCache.get(mainTemplateLocation);
    $compile(templatesHTML)($rootScope);
}));

Conclusion

Note that the instructions for 0.8.x may require adjustments and testing, unlike the compatibility assured for 0.10.x.

Karma offers utilities for incorporating external HTML partials into tests – all that was lacking was the correct interpretation of the main template.
