Test Plan

"Brave.Today.HasEverInteracted",

0. Fresh profile
1. Open NTP
2. Scroll down to see some Brave Today content
3. p3a metric should be 1

"Brave.Today.WeeklySessionCount",

p3a metric should reflect the bucket (as above) of the amount of times Brave Today has been scrolled to.

"Brave.Today.WeeklyMaxCardViewsCount",

Counts how many cards have been scrolled down to per session (i.e. scroll depth)
0. Fresh Profile

1. Open NTP
2. Scroll down a little bit
   --> Observe: p3a metric should show a lower bucket (described above) to describe the amount of cards viewed in this session
3. Start a new Brave Today session and scroll much further
   --> Observe: p3a metric should now show a higher bucket
4. Start a new Brave Today session and only scroll a little amount
   --> Observe: p3a metric should still be at the previous higher bucket

"Brave.Today.WeeklyMaxCardVisitsCount",

Counts how many cards have been clicked per session (either clicking then going back then clicking another, or by cmd/ctrl-clicking more than 1)
0. Fresh Profile

1. Open NTP
2. Click a Brave Today content card
   --> Observe: p3a metric should show a lower bucket (described above) to describe the amount of cards viewed in this session
3. Start a new Brave Today session and click a card
   --> Observe: p3a metric should still show the lower bucket as this is a new session and we've only clicked 1 card
4. Navigate back and click another card
   --> Observe: p3a metric should now show a higher bucket
5. Repeat: Navigate back and click another card
   --> Observe: p3a metric should now show an even higher bucket
