Angular Protractor with BrowserStack behind a proxy - angularjs

Question

I want to build a Testsuite for an Angular App. The testsuite should use the framework "Protractor".
When I start the testsuite local with protractor local.config.js, then the test are running successful.
When I start the testsuite with BrowserStack without proxy, also everything are okay.
Now my question:
What settings do I have to do if I want to perform the test by local browser stack behind a proxy?
Main BrowserStack configuration:
var
proxy = 'http://proxy.example.com:8888';
exports.config = {
capabilities: {
project: 'BrowserStack (beyond Proxy)',
proxy: {
proxyType: 'manual',
httpProxy: proxy,
sslProxy: proxy,
},
loggingPrefs: {
driver: "FINE",
server: "OFF",
browser: "FINE"
},
'browserstack.user': 'USER_KEY',
'browserstack.key': 'ACCESS_KEY', // show on BrowserStack
// Needed for testing localhost
'browserstack.local' : 'true',
// Settings for the browser you want to test
// (check docs for difference between `browser` and `browserName`
'browserName' : 'chrome',
'version' : '43.0',
'os' : 'OS X',
'os_version' : 'Yosemite',
'resolution' : '1024x768'
},
seleniumAddress: 'http://hub.browserstack.com/wd/hub',
specs: [
'test/e2e/**/*.spec.js'
]
};
I call the script "BrowserStackLocal" with this parameters:
./BrowserStackLocal -v -proxyHost PROXY_DOMAIN -proxyPort PROXY_PORT $ACCESS_KEY localhost,$PORT,0
Stepts:
start the application on my local computer node app.js
start the script "BrowserStackLocal"
start the protractor with the browserstack configuration from above.

Answer 1

When you are behind a proxy server, you need to do two things:
If you are testing your local server, you need to setup the Local Testing connection by passing the proxy details, which I assume you are doing.
You have to make sure the Selenium requests made via Protractor also reach BrowserStack. The easiest option would be to use global-tunnel npm package. If your proxy is behind an Authentication, you can try using the tunnel npm module.

Answer 2

You no longer need to use global-tunnel. There is now a new configuration option webDriverProxy:
exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
webDriverProxy: 'http://127.0.0.1:8888',
capabilities: {
browserName: 'chrome'
},
specs: ['*.spec.js'],
};
