How to use an angular test file?

I have a test file like what is at the end. I have tried node FILENAME, npm FILENAME, which get me errors. I've also tried npm test which seem to test something else (attached after the testing file). I'm new to angular and looked at the demo but, Im not really sure what I should be doing.

Code from here: https://github.com/vega/vega-lite-ui (not mine)

testing file:

'use strict';

/* global vl:true */

describe('Directive: bookmarkList', function () {
  var element,
    scope;

  afterEach(inject(function(Modals) {
    // Remove any modals registered during the tests
    Modals.empty();
  }));

  beforeEach(module('vlui', function($provide) {
    // mock vega lite
    $provide.constant('vl', vl);
  }));

  beforeEach(inject(function ($rootScope) {
    scope = $rootScope.$new();
    scope.active = true;
  }));

  it('requires a parent modal directive', inject(function ($compile) {
    // This is a side-effect of the modalCloseButton directive inside bookmarkList
    element = angular.element('<bookmark-list></bookmark-list>');
    expect(function() {
      $compile(element)(scope);
    }).to.throw;
    element = angular.element('<modal><bookmark-list></bookmark-list></modal>');
    expect(function() {
      $compile(element)(scope);
    }).not.to.throw;
  }));

  describe('when opened', function() {
    beforeEach(inject(function(Modals, $compile) {
      var template = '<modal id="test-bookmarks"><bookmark-list></bookmark-list></modal>';
      element = $compile(angular.element(template))(scope);
      Modals.open('test-bookmarks');
      scope.$digest();
    }));

    // TODO: Tests that validate the directive works properly
  });
});

npm test results:
