> For many cases this would also fall under the free tier since it not that many requests/usage...it kinda seems too good to be true

(since I've ran into the same trap a couple of weeks ago and ended up with USD 650 of unanticipated charges): the free Lambda tier includes

* 1M requests

* 400k GB-seconds

--> the GBsec can be a serious bottleneck. Imagine you're running each Lambda instance with 512MB RAM and each instance takes 2 mins to complete your test. This means that one Lambda instance is ~61.5 GBsec, meaning you can execute ~6,500 of these instances per month to remain in the free tier.

Depending on how extensive your tests are/how often you run them, you might run out of free GBsec well before you'd run out of the requests quota.

Granted that means running ~216 instances per day, or 9 instances per hour (taking 18 minutes per hour to run total). Now you're right, if you're running a screenshot service then this will kill you real fast.

However assuming a 8 hour work day you then get ~27 instances per hour. Each test takes two minutes to run, so for a single user testing, assuming a code - test - code - test routine, you'd be able to do that nearly continuously, for 8 hours a day, every day of the month (no weekends or days off). Seems safe to assume that wouldn't occur.
