For the test bestStrategy(60, 10, 1), your test is looking for the strategy to be "HSS". The two pitstops take a total of 20 seconds. The 30 laps on soft tires reduce your overall time by 30 seconds. Thus, the "HSS" strategy yields 20 - 30 = -10 seconds savings in your overall time.

If however, you ran a single lap with hard tires and then ran the rest of the race on soft tires you would have an "HSSSS" strategy. The four pitstops take a total of 40 seconds. The 59 laps run on soft tires reduce your overall time by 59 seconds. Thus, the "HSSSS" strategy yields 40 - 59 = -19 seconds savings in you overall time, a far better strategy than "HSS".

I don't think the desired results are always optimal.

Nice kata!
Really enjoyed working through this one — clean, well‑designed, and satisfying to implement.
Thanks for creating it!

Python : Random tests to be updated to avoid solutions like this

The weirdest solutions pass in JS: https://www.codewars.com/kata/reviews/56b5ebb026fd54188b00001a/groups/62b35e53889d9000016ee91c
Tests should be improved.

JS: Random test rarely generate descriptive numbers.
