You have installed the Katalon TestCloud Keywords plugin from Katalon Store. If you have not, visit: Katalon TestCloud Keywords.
When executing WebUI tests with TestCloud, in some scenarios, you may want to download files and verify them. The following is a ready-to-use FileExecutor class that contains custom keywords for downloading and verify files. The keyword file should be placed under the com.katalon.testcloud package.
In Katalon Studio, click the Profile drop-down and select Reload Plugins to make sure the plugin is installed.
Add the FileExecutor.pushFiletoDevice keyword to your test case.
Configure your TestCloud mobile environment and run the test.
