Error in recorder (2.0.0-RC2)

Gatling (Open-Source)

I set up the recorder, and set up my browser (Safari) to go through it. Then I pointed my browser to http://www.Booker.com and clicked the login link, and I get the following error.

Hi John,

I checked on my machine, It seems to work for me - recorder RC2, safari, www.booker.com.

Looking at the error:
java.nio.channels.UnresolvedAddressException

This suggests that you cannot resolve www.booker.com to an IP address?

I am guessing it might not be as simple as that but currently that is all I see from this.

Can you try a couple of other things like

does it work for other sites?
run “nslookup www.booker.com” from the command prompt, or “grep booker /etc/hosts”, to determine if your machine can resolve booker to an IP address?
point safari to another proxy (eg. charles proxy) as a control test to see if it is the gatling proxy or something in the safari/system set up?
does it work on RC1 or M3?

Thanks,
Alex

I am having more of a look:

  • I do get those errors in the logs. I missed them because of a previous error which I ignored as it related to a control test I did before accessing www.booker.com. However, I haven’t noticed any error with booker.com home page.

  • I got this when accessing the login link through the recorder (works ok direct):
    (going to: https://app.secure-booker.com/App/Admin/Login.aspx)
    no error in the recorder logs.
    do you see this or something different?

Server Error in ‘/’ Application.

… it appears to work with the snapshot I had from the 24th July, but not RC1.

Will have a look to bisect which commit this evening if time.

Let me know what you find, because I could really use the recorder to tell me what is happening between my browser and their server as I navigate around. I’m trying to automate report generation.

I’ll investigate.
In the mean time, if you’re in desperate need of the Recorder, you still have to ability to create a HAR (Http ARchive) file from your navigation and export it to a Gatling simulation with the Recorder.

Cheers,

Pierre

Hi John,
This should be fixed in latest snapshot by a change from James Pickering.
http://gatling.io/docs/2.0.0-RC2/developing_gatling/building_gatling.html?highlight=snapshot

Let us know if there’s any further issues so they can be resolved before 2.0.

Thanks,
Alex
