How to connect and re-use an already opened browser window in Protractor

Question

In general, the protractor scripts are executed in a new browser instance with the following capabilities

capabilities: {
'browserName': 'firefox'
}

Is there any snippets or ways to tweak this; so that our scripts make use of an already opened browser through protractor.

you meant, you just want to open a browser one time and use it for executing all scripts? — Optimworks, Jul 19 '16 at 07:48
@SureshSalloju I open a browser, quits the driver; again I want the same browser to execute my other test. — Prashanth Sams, Jul 19 '16 at 08:09
use beforeAll()- for browser opening and afterAll() - for quit the driver — Optimworks, Jul 19 '16 at 08:11
No, I want to re-use the existing browser; how to achieve it. — Prashanth Sams, Jul 19 '16 at 08:12

What worked for me, for angular2:

Go to WebDriverHub and click on Create Session, copy the generated id (eg: 2919ed90-efac-48ee-83df-46f8e98ebce7), you'll need it in step#2.
Add/Modify protractor.conf.js to reflect the following.

exports.config.seleniumAddress: 'http://localhost:4444/wd/hub', exports.config.seleniumSessionId: '2919ed90-efac-48ee-83df-46f8e98ebce7', exports.config.directConnect: false

Observe:

Setting directConnect to false is important.
seleniumSessionId will need to be updated everytime u create new session (wish there was a way to tell, use current running browser window without updating seleniumSessionId everytime)

On this line you have an example on how it's passed on the command line to Protractor: https://github.com/angular/protractor/commit/3f3805f9496fb130ae01b3e3278ee1ea7684d8e7#diff-b61b72dbab31e232fdb8466ebf733c4dR54 You can use the same parameter in your config to pass the current session ID. You can usually get the current sessionId by browser.getSessionId Example 1:

var runProtractor = spawn('bin/protractor',
     ['spec/attachSession.js', '--seleniumSessionId=' + currentSessionId]);

Example 2 using your config:

var checkOptions = {
     hostname: 'localhost',
     port: 4444,
     seleniumSessionId: yourCurrentSessionId
....
}

Use browser.getCapabilities() to get the debugger address. Using the debugger address we can communicate with the existing browser. In the below link I've written an article on this, take a look into this.
