# Artifacts in Device Farm desktop browser testing
<a name="managing-artifacts"></a>

 Artifacts are created automatically in Device Farm when your tests perform actions like opening or closing a session. 

The following kinds of artifacts are produced:
+ Video recording of your test. Recording starts when your session starts and ends when your session times out or is closed.
**Note**  
For long-running test sessions, videos are split at even intervals. Even test runs that go just over one of these intervals are still split. 
+ Selenium logs produced by the Selenium WebDriver.

Session artifacts have the following properties:
+ Type (video, log, other).
+ File name.
+ Limited lifetime S3-signed URL that can be used to retrieve the artifact.

A new URL is generated whenever the artifact is requested as a part of an API request. This URL expires after an hour.
