Unable to download a file when chromedriver is in headless mode. How to get it work?

During the test, a file (.html) will be downloaded from the web application & I have to verify that file by opening it on the browser. In the non-headless mode, my test is working fine. But whenever I'm going to headless mode, that file is not getting downloaded to the download path (i.e. pointed in the "user.dir"). My chrome driver version is 2.44.609538 & selenium version is 3.14.

I met same situation.

Headless mode is very faster. So your code might be implemented to detect download(DL).

Solution.

  1. (Current your process?) .click for DL -> Detecting download file generation.
  2. (My solution) Detecting download file generation -> .click for DL.

I implemented the above mechanism using callback function.

This worked for our ruby implementation:

Capybara.register_driver :scrapping_driver do |app|
      options = Selenium::WebDriver::Chrome::Options.new
      options.add_argument('--headless')
      options.add_argument('--disable-popup-blocking')
      options.add_argument('--disable-gpu')
      options.add_argument('--no-sandbox')
      options.add_argument('--disable-dev-shm-usage')
      options.add_argument('--window-size=1366,2000')
      options.add_preference(:download, directory_upgrade: true,
                                prompt_for_download: false,
                                default_directory: "#{Rails.root}/")
      options.add_preference(:browser, set_download_behavior: { behavior: 'allow' })
      Selenium::WebDriver::Service.driver_path = Webdrivers::Chromedriver.driver_path
      driver = Capybara::Selenium::Driver.new(app, browser: :chrome, options: options)
    end

Pay attention at download behaviour

Are you running the test from the command line?

Because, according to an answer to this question and this, when you run it via command line, your user.dir corresponds to your global user directory (C:\users\username).
