How to pass language setting to Chrome webdriver?

[Tset Noitamotua]

Hi guys!

Does somebody know how to pass the chomeOption '--lang=xx' to Chrome webdriver?

I have made this keyword:

| Open URL in Google Chrome | [Arguments] | ${url}
| | [Documentation] | Starts the Google Chrome browser.
| | ${options}= | Evaluate | sys.modules['selenium.webdriver'].ChromeOptions() | sys, selenium.webdriver
| | Call Method | ${options} | add_argument | --lang=de
| | Create WebDriver | Chrome | chrome_options=${options}
| | Go To | ${url}

When I use this keyword I get this error:

TRACE: Arguments: [ <selenium.webdriver.chrome.options.Options object at 0x03307270> | 'add_argument' | --lang='de' ]

FAIL: Calling method 'add_argument' failed: TypeError: add_argument() got an unexpected keyword argument '--lang'

How can I make chromedriver to start with German locale instead of it's default English?

My solution so far in Python interactive shell:

from selenium import webdriver
lang_de = webdriver.ChromeOptions()
lang_de.add_argument("--lang=de")
chrome = webdriver.Chrome(chrome_options=lang_de)


This starts a Chrome browser with German locale.

Now I need to translate this into Robot Framework syntax.

Final solution in Robot Framework syntax:

| Open URL in Google Chrome | [Arguments] | ${url}
| | [Documentation] | Starts the Google Chrome browser.
| | ${options}= | Evaluate | sys.modules['selenium.webdriver'].ChromeOptions() | sys

| | Call Method | ${options} | add_argument | --lang\=de

| | Create WebDriver | Chrome | chrome_options=${options}
| | Go To | ${url}

Actually I just needed to escape the equal sign: instead '--lang=de' one need to write '--lang\=de'

Thanks, for sharing the problem, hypothesis, experimentation and conclusion.

Gallileu Gallilei would be proud of you!

(really, that example would be nice to have in an advanced blog or wiki about RF/S2L)

Ugh

That would be nice example to the keyword documentation.

Ugh

Did open a issue [1], so that we actually remember to decide and perhaps implemented the improvement.

Regarding your python code - do you need to return something from python?
Because for me browser is opened, language is correct but that's all. No possible more interaction with browser.
If I try robotcode then I can't set user-data-dir (iI need also user data dir)
Some help?

@Igor: What do you meen by "No possible more interaction with browser"?

Try all these steps in Python interactive shell:

from selenium import webdriver
lang_de = webdriver.ChromeOptions()
lang_de.add_argument("--lang=de")
chrome = webdriver.Chrome(chrome_options=lang_de)

chrome.get("http://www.google.com")
search_input = chrome.find_element_by_xpath("//input[@class='gsfi']")
search_input.send_keys("I love Python!")
search_button = chrome.find_element_by_xpath("//button[@class='lsb']")
search_button.click()

See the magic? ;-)

I am using this mainly to check whether the locator or xpath expression I´m planning to use in test code is working correctly.

Ok. My mistake. I forget to mention that I'm using robot framework to write test, but Ii have some, let's say, a custom library from where I execute python code calling it from ROBOT.
So I call this method, to run chrome and then I want to continue with robot keywords execution...
Like when you have in robot:

Open Browser  url   browser
GoTo   google2.com

Thank you so much!

Thanks Alot!

It works also for --user-data-dir\=,  --log-path\=.

This solution should work for any argument which throw the given error:  FAIL: Calling method 'add_argument' failed: TypeError: add_argument() got an unexpected keyword argument.
