running selenium-side-runner with a chrome profile.

Dear GitHub community,

I have been desperately trying to run selenium-side-runner with a specific Google Chrome profile, using the command line switch user-data-dir

I'm on Windows 7 64 bits.

Unfortunately, after every trial, chrome://version shows that the profile directory is a temporary one (default behaviour of chromedriver).

Here's what I tried :

  • using slashes in data directory path: selenium-side-runner -c "chromeOptions.args=[user-data-dir=C:/Users/LeNoVo/AppData/Local/Google/Chrome/User Data/Profile 1]" -c "chromeOptions.args=[fake-arg]" c:\Users\Me\path\demo.side
  • using back-slashes in data dir path: selenium-side-runner -c "chromeOptions.args=[user-data-dir=C:\Users\LeNoVo\AppData\Local\Google\Chrome\User Data\Profile 1]" -c "chromeOptions.args=[fake-arg]" c:\Users\Me\path\demo.side
  • using two back-slashes: selenium-side-runner -c "chromeOptions.args=[user-data-dir=C:\\Users\\LeNoVo\\AppData\\Local\\Google\\Chrome\\User Data\Profile 1]" -c "chromeOptions.args=[fake-arg]" c:\Users\Me\path\demo.side
  • I also did all of the above, but with the data dir path stopping at \User Data , plus the argument -c "chromeOptions.args=[profile-directory="Profile 1"]"


Note: the "fake-arg" turns out to be necessary, because webdriver (or selenium-side-runner) expects arguments to be an array, not a single string. So I include that fake-arg to overcome that issue.


Any help would be appreciated.

Thank you in advance.

Re: running selenium-side-runner with a chrome profile.

According to this answer on SO, you can also define this profile in the code itself. Wouldn't that be easier to do?

Re: running selenium-side-runner with a chrome profile.

You mean by the command line option profile-directory="Profile 1"  ?

I tried that , it didn't work.


I'm not sure what you mean by "the code itself".

You mean I open the .side file and edit it ?

Re: running selenium-side-runner with a chrome profile.

With "the code itself" I meant your test cases in Selenium which you have written in (for example) Python or JavaScript. I was referring to this code snippet:

m_Options = new ChromeOptions();
m_Options.AddArgument("--user-data-dir=C:/Users/Me/AppData/Local/Google/Chrome/User Data/Default");
m_Driver = new ChromeDriver(@"pathtoexe", m_Options);

on the SO answer. Could you try to incorporate this into your test cases?


Also what's up with the fake-arg?

Thank you.

  • I tried to incorporate that snippet using "execute script" command of Selenium IDE.

However, it did not work.

selenium-side-runner encountered an error : 

WebDriverError: unknown error: ChromeOptions is not defined

  • Concerning "fake-arg" , I found that solution in SO, too :

Well, I can't really tell what is going wrong there then...


If you don't get enough engagement on your post here, you could consider asking your question, for example, here:!forum/selenium-users . You could even link this thread here.
