Test a downloaded file assertion allow you to verify that downloadable files from your web application are correctly being served (for example, from your FTP server). With this assertion, downloadable files can be tested to ensure they have the correct file name, size, and data.
To setup a browser test with this assertion:

Test a downloaded file assertion.
Confirm that the file was downloaded and matched the requirements you set up in your assertion by looking at the generated test result:
