/**
|
|
* Note about testing
|
|
* It is difficult to test file downloads as Selenuim and javascript do not provide
|
|
* an easy way to control native dialogs.
|
|
* One approach would be to configure the test browser to automatically start the download and
|
|
* save the file in a specific place. Then check that the file exists at that location.
|
|
* Firefox documentation: http://kb.mozillazine.org/File_types_and_download_actions
|
|
* Approach detailed here in java: https://www.seleniumeasy.com/selenium-tutorials/verify-file-after-downloading-using-webdriver-java
