+    A workload to perform standard productivity tasks within YouTube.
+
+    The workload plays a video from the app, determined by the ``video_source`` parameter.
+    While the video is playing, a some common actions are done such as video seeking, pausing
+    playback and navigating the comments section.
+
+    Test description:
+    The ``video_source`` parameter determines where the video to be played will be found
+    in the app. Possible values are ``search``, ``home``, ``my_videos``, and ``trending``.
+
+    -A. search - Goes to the search view, does a search for the given term, and plays the
+        first video in the results. The parameter ``search_term`` must also be provided
+        in the agenda for this to work. This is the default mode.
+    -B. home - Scrolls down once on the app's home page to avoid ads (if present, would be
+        first video), then select and plays the video that appears at the top of the list.
+    -C. my_videos - Goes to the 'My Videos' section of the user's account page and plays a
+        video from there. The user must have at least one uploaded video for this to work.
+    -D. trending - Goes to the 'Trending Videos' section of the app, and plays the first
+        video in the trending videos list.
+
+    For the selected video source, the following test steps are performed:
+
+    1.  Navigate to the general app settings page to disable autoplay. This improves test
+        stability and predictability by preventing screen transition to load a new video
+        while in the middle of the test.
+    2.  Select the video from the source specified above, and dismiss any potential embedded
+        advert that may pop-up before the actual video.
+    3.  Let the video play for a few seconds, pause it, then resume.
+    4.  Expand the info card that shows video metadata, then collapse it again.
+    5.  Scroll down to the end of related videos and comments under the info card, and then
+        back up to the start. A maximum of 5 swipe actions is performed in either direction.
