If you want to set browser specific options for an automation test in Pytest on Lambdatest, you can use the following steps. You can refer to sample test repo here.

You can specify the various browser specific options in the conftest.py file. The following is an example on how to set Chrome specific options using chromeOptions:

capabilities = {
       "build": "Sample PY Build",
       "platformName": "Windows 11",
       "browserName": "Chrome",
       "browserVersion": "latest",
       "chromeOptions" : {
               "args" : ["incognito"]  # ChromeOption to start chrome in incognito mode
 }
}

• The different options available for Chrome can be referred to here.
