How to access the downloaded file and verifying its content within Virtuoso.

Problem Statement:

In automated testing scenarios, it is often necessary to verify the content of a file that has been downloaded during a test. Manually checking the downloaded file for specific content, format, or file properties can be both time-consuming and inefficient. Users require a streamlined way to not only download files as part of a test but also validate the file’s content directly within Virtuoso.

This article provides a solution for accessing and verifying the details and content of downloaded files within Virtuoso using built-in variables and extensions.

Solution:

When a file is downloaded as a result of a test step (e.g., clicking a download link), it is automatically stored in Virtuoso for easy access and validation. The file or its details can be accessed by using two newly created variables:

1. LAST_DOWNLOADED_FILE
2. LAST_DOWNLOADED_FILE_DETAILS

How to access the properties of a downloaded file : 

Steps:

1. Execute the Download Step:

• Perform the test step to download the file (e.g., clicking the "Download" button). The file will be downloaded and stored in the Virtuoso browser.

2. Check Download Details:

• Navigate to the Side Effects tab for this test step to view the details of downloaded files.
• LAST_DOWNLOADED_FILE: Stores the URL of the downloaded file.
• LAST_DOWNLOADED_FILE_DETAILS: Stores the details associated with the downloaded file.

3. Verify File Properties:

• You can verify the filename, size, and length of the downloaded file using the variable $LAST_DOWNLOADED_FILE_DETAILS along with the "Assert" command to ensure the accuracy of all aspects of the downloaded file.
