Is there a way, to automate file browse and select action of HTML Input FileUpload Object, using chrome extension ?
Like 'sendkeys' in selenium. (driver.FindElement(By.Id("Update_file")).SendKeys(DS_File) )
Also is 'sendkeys' supported in chrome extension?
Do you want to emulate the actions taken by a user to select a file in de file selector? Because that is impossible. The only thing that works is sendKeys, but as you already mentioned it, I am not sure that is what you are asking for.
