No random tests

C# fork

• random tests
• moved the Animal class to preloaded
• overrode Equals to be able to compare Animals directly
• added purity checks, since the description explicitely asks for a new list

Not backwards-compatible, because the Animal class was defined in the user file instead of preloaded, which I think is bad. Feedback is welcome, I'm not proficient in C#

Scala translation

C#:

• Actual and expected in some fixed tests are swapped

• No random tests

There are possible sources of floating point errors in the kata (mostly on AverageLitres), which the tests doesn't account for.

the total distance driven will be the difference between the odometer reading of the last fill-up for the month, and the odometer reading of the first fill-up for the month.

Odometer wraps around at certain values, and there is no guaranteed that it will always be strictly increasing over time for the entire span of input data either (for example, if it is replaced or tampered with). Unless it is strictly increasing there will be a difference in last - first vs. max - min, so either this should be explicitly specified, or it should be specifically tested.

FillUp and MonthlyFillUpSummary should not be defined in user code space. They should be defined in Preloaded.

Description should be language-agnostic

• Node 14 should be enabled (Refer this and this for more info)

• Ruby 3.0 should be enabled (Refer this & this for more detail)

JS: The description is misleading. There's no class here. Just arrays of plain objects.

Tests compare each property of the returned objects separately without any indication of what exactly is being tested.

No random tests.

You might want to merge both the basic tests into one.
