Nightwatch: Start two browsers

[acroix]

@beatfactor
Do you know if there is a way to start 2 browsers ? I mean with only one command
For example if I need to test a chat, is there a way to test it with a second client ?

I did it with selenium but didn't find a way to do it using nightwatch

_Interesting!_

I don't believe nightwatch supports this yet, testing of two browsers at the same time. What if you had two different nightwatch sessions running at the same time and passed in a different environment with the --env operation?

[beatfactor]

No, it doesn't but it's certainly something to consider for the future.

@beatfactor Yes that would be a really interesting feature. Btw it was possible to do it with the selenium protocol so maybe we can see how implement the feature
@jordan112 To do it I need to open another terminal to start a new nightwatch runner... That's a problem because running a new terminal depend on your system configuration.

I think it might be possible using the cluster module and spawning a new
worker for each target browser.

Ok I did a test with cluster and workers, that's working !
So first, thanks !

Here is the poc:

var cluster = require('cluster');
var exec = require('child_process').exec;

if (cluster.isMaster) {

    cluster.fork().on('online', function () {
        exec('./nightwatch local -e chrome -t tests/chat/client1.js', function (error, stdout, stderr) {
            console.log('stdout: ' + stdout);
            if (error !== null) {
                console.log('exec error: ' + error);
            }
        });

        this.kill();
    });

    cluster.fork().on('online', function () {
        exec('./nightwatch local -e chrome -t tests/chat/client2.js', function (error, stdout, stderr) {
            console.log('stdout: ' + stdout);
            if (error !== null) {
                console.log('exec error: ' + error);
            }
        });

        this.kill();
    });
}

Possible next step can be :

• Target browsers we want to use
  
  
  
  • with nightwatch cli ?
  
  
• If the user want to use "multibrowser"
  
  
  
  • new workers for each target browser
  
  
  • each workers start a new nightwatch runner
  
  

@beatfactor What do you think ?

[beatfactor]

Yes, this is a good start.

            console.log('exec error: ' + error);
        }
    });

    this.kill();
