AngularJS e2e testing in Rails stack: [object Object] has no method 'resumeBootstrap' - ruby-on-rails

Question

It seems quite hard to get the AngularJS/Karma end-to-end testing environment working with a Rails backend.
I have Karma installed and running with the following config file:
basePath = '../';
files = [
ANGULAR_SCENARIO,
ANGULAR_SCENARIO_ADAPTER,
'test/e2e/**/*.js'
];
autoWatch = false;
browsers = ['Chrome'];
// singleRun = true;
proxies = {
'/': 'http://local.mywebsite.com:3000/'
};
urlRoot = 'e2e';
junitReporter = {
outputFile: 'test_out/e2e.xml',
suite: 'e2e'
};
Where http://local.mywebsite.com:3000/ is my rails application.
I try a very simple test:
it('should redirect to /', function() {
expect(browser().location().url()).toBe("/");
});
But I am stuck with the following error:
http://localhost:9876/base/test/e2e/scenarios.js:8:5
TypeError: Object [object Object] has no method 'resumeBootstrap'
at HTMLIFrameElement.<anonymous> (http://localhost:9876/adapter/lib/angular-scenario.js:26285:27)
at HTMLIFrameElement.jQuery.event.dispatch (http://localhost:9876/adapter/lib/angular-scenario.js:3064:9)
at HTMLIFrameElement.elemData.handle.eventHandle (http://localhost:9876/adapter/lib/angular-scenario.js:2682:28)
at k (http://connect.facebook.net/en_US/all.js:48:745)
Where scenarios.js comes from https://github.com/angular/angular-seed.
Any idea how to make it work?

Answer 1

Try
it('should redirect to /', function() {
browser().navigateTo("/");
expect(browser().window().path()).toBe("/");
});

I would get the most up-to-date version of angular scenario runner. You can find the unstable version at
http://code.angularjs.org/1.1.4/angular-scenario.js
and the stable version at
http://code.angularjs.org/1.0.6/angular-scenario.js
Then, be sure to update your karma configuration to use the newest scenario runner
files = [
'path/to/angular-scenario.js',
ANGULAR_SCENARIO_ADAPTER,
'test/e2e/**/*.js'
];
Hopefully that helps.

The solution above is correct. This link covers the problem: https://github.com/karma-runner/karma/issues/470
I hit the same issue while running the excellent examples on: http://www.yearofmoo.com/2013/01/full-spectrum-testing-with-angularjs-and-testacular.html
That's a great resource if you're getting started, but you will need to update from testacular to karma and update angularjs to 1.0.6
