Add file upload test for Selenium driver
Is your feature request related to a problem? Please describe.
Selenium driver rocks! But upload file does not work properly when working with remote files. Add an example test for this.
Describe the solution you'd like
Unfortunately, we can not use \Behat\Mink\Driver\Selenium2Driver::uploadFile()
for get remote path to file. Drupal added Drupal\Tests\Traits\Core\SeleniumUploadRemoteFileTrait
for that we should add test using that.
Describe alternatives you've considered N/A
