Uploads a file to the Selenium instance and returns the remote path.

\Behat\Mink\Driver\Selenium2Driver::uploadFile() is a private method so that can't be used inside a test, but we need the remote path that is generated when uploading to make sure the file reference exists on the container running selenium.

Parameters

string $path: The path to the file to upload.

Return value

string The remote path.

Throws

\Behat\Mink\Exception\DriverException When PHP is compiled without zip support, or the file doesn't exist.

\WebDriver\Exception\UnknownError When an unknown error occurred during file upload.

\Exception When a known error occurred during file upload.
