My tests are working on my Linux machine, but once I moved to Mac, i’m getting an error.
[ ERROR ] Error. … on line 4: Initializing library ‘SeleniumLibrary’ with arguments [ plugins=SeleniumTestability;True;30 Seconds;True ] failed: Importing test library ‘SeleniumTestability’ failed: AttributeError: type object ‘DesiredCapabilities’ has no attribute ‘OPERA’
Opera is not supported with resent versions of Selenium. You need to find Selenium version which supports Opera and SeleniumLibrary which supports that version of Selenium.
